T7 polymerase-driven transcription is downregulated in metacyclic promastigotes and amastigotes of Leishmania mexicana

Aygul Ishemgulova, Natalya Kraeva, Drahomíra Faktorová, Lucie Podešvová, Julius Lukeš, Vyacheslav Yurchenko

Folia Parasitologica 63:016 (2016) | DOI: 10.14411/fp.2016.016

In our previous work we established a T7 polymerase-driven Tetracycline-inducible protein expression system in Leishmania mexicana (Biagi, 1953). We used this system to analyse gene expression profiles during development of L. mexicana in procyclic and metacyclic promastigotes and amastigotes. The transcription of the gene of interest and the T7 polymerase genes was significantly reduced upon cell differentiation. This regulation is not locus-specific. It depends on untranslated regions flanking open reading frames of the genes analysed. In this paper, we report that the previously established conventional inducible protein expression...

Two new species of Rhabdias Stiles et Hassall, 1905 (Nematoda: Rhabdiasidae) from anuran amphibians in Pará, Brazil

Yuriy Kuzmin, Francisco Tiago de Vasconcelos Melo, Heriberto Figueira da Silva Filho, Jeannie Nascimento dos Santos

Folia Parasitologica 63:015 (2016) | DOI: 10.14411/fp.2016.015

Two new lung-dwelling nematode species of the genus Rhabdias Stiles et Hassall, 1905 were discovered in Caxiuanã National Forest, Pará state, Brazil. Rhabdias galactonoti sp. n. was found in a dendrobatid frog Adelphobates galactonotus (Steindachner). The species is characterised by the regularly folded inner surface of the anterior part of the buccal capsule seen in apical view, flask-shaped oesophageal bulb and narrow, elongated tail. Rhabdias stenocephala sp. n. from two species of leptodactylid frogs, Leptodactylus pentadactylus (Laurenti) (type host) and L. paraensis (Heyer), is characterised by...

Morphological and molecular descriptions of Moniliformis saudi sp. n. (Acanthocephala: Moniliformidae) from the desert hedgehog, Paraechinus aethiopicus (Ehrenberg) in Saudi Arabia, with a key to species and notes on histopathology

Omar M. Amin, Richard A. Heckmann, Osama Mohammed, R. Paul Evans

Folia Parasitologica 63:014 (2016) | DOI: 10.14411/fp.2016.014

A new acanthocepohalan species, Moniliformis saudi sp. n. is described from the desert hedgehog, Paraechinus aethiopicus (Ehrenberg), in central Saudi Arabia. Fourteen other valid species of Moniliformis Travassos, 1915 are recognised. The new species of Moniliformis is distinguished by having a small proboscis (315-520 µm long and 130-208 µm wide) with two apical pores, 14 rows of 8 hooks each and small hooks, thre largest being 25-31 µm long anteriorly. Distinguishing features are incorporated in a dichotomous key to the species of Moniliformis. The description is augmented by scanning electron...

The molecular phylogeny of the digenean family Opecoelidae Ozaki, 1925 and the value of morphological characters, with the erection of a new subfamily

Rodney A. Bray, Thomas H. Cribb, D. Timothy J. Littlewood, Andrea Waeschenbach

Folia Parasitologica 63:013 (2016) | DOI: 10.14411/fp.2016.013

Large and small rDNA sequences of 41 species of the family Opecoelidae are utilised to produce phylogenetic inference trees, using brachycladioids and lepocreadioids as outgroups. Sequences were newly generated for 13 species. The resulting Bayesian trees show a monophyletic Opecoelidae. The earliest divergent group is the Stenakrinae, based on two species which are not of the type-genus. The next well-supported clade to diverge is constituted of three species of Helicometra Odhner, 1902. Based on this tree and the characters of the egg and uterus, a new subfamily, the Helicometrinae, is erected and defined to include the genera Helicometra,...

Seroprevalence and risk factors of infections with Neospora caninum and Toxoplasma gondii in hunting dogs from Campania region, southern Italy

Tereza Machačová, Eva Bártová, Kamil Sedlák, Radka Slezáková, Marie Budíková, Diego Piantedosi, Vincenzo Veneziano

Folia Parasitologica 63:012 (2016) | DOI: 10.14411/fp.2016.012

Hunting dogs have probably a higher level of exposure to Neospora caninum Dubey, Carpenter, Speer, Topper et Uggla, 1988 and Toxoplasma gondii Nicolle et Manceaux, 1908 than other canine populations for their different lifestyle. The aim of our survey was to determine the seroprevalence of N. caninum and T. gondii in hunting dogs from southern Italy and assess risk factors related to these protozoan infections. Blood samples were collected from 398 hunting dogs (19 different breeds, aged from 5 month to 14 years). The sera were screened by indirect fluorescence antibody test; a titre ≥ 50 was considered positive. Antibodies...

Intraspecific morphometric variation in myxosporeans

Yanhua Zhai, Christopher M. Whipps, Zemao Gu, Qingxiang Guo, Zizhen Wu, Hongmei Wang, Yang Liu

Folia Parasitologica 63:011 (2016) | DOI: 10.14411/fp.2016.011

Morphometric data from spores of ten myxosporean species were statistically analysed to explore myxosporean intraspecific variation in measurements when obtained from a sample from: (1) the same plasmodium, (2) different plasmodia from the same host and (3) different host individuals and localities. In some cases, significant differences in spore dimensions were found between samples from the same plasmodium, highlighting the difficulty of obtaining representative measurements of myxosporean spore. In addition, significant differences in spore dimensions were found when plasmodia from the same site of infection were compared, suggesting that measurements...

Bacillus Calmette-Guérin-inoculation at different time points influences the outcome of C57BL/6 mice infected with Plasmodium chabaudi chabaudi AS

Dong-Hua Cao, Ji-Chun Wang, Jun Liu, Yun-Ting Du, Li-Wang Cui, Ya-Ming Cao

Folia Parasitologica 63:010 (2016) | DOI: 10.14411/fp.2016.010

Bacillus Calmette-Guérin (BCG) is an attenuated Mycobacterium tuberculosis vaccine. We performed a series of co-infection experiments with BCG-Plasmodium chabaudi chabaudi Landau, 1965 AS using C57BL/6 mice to analyse whether BCG can affect the development of protective immunity to infection with Plasmodium spp. and the mechanism of this protection. We divided mice into four groups: BCG-inoculation 4 weeks prior to P. c. chabaudi AS infection (B-4w-Pc); simultaneous BCG-inoculation and P. c. chabaudi AS infection (Pc+B); BCG-inoculation 3 days post P. c. chabaudi AS (Pc-3-B) infection; and mono-P. c. chabaudi...

The first detection of species of Babesia Starcovici, 1893 in moose, Alces alces (Linnaeus), in Norway

Irma Pūraitė, Olav Rosef, Jana Radzijevskaja, Indrė Lipatova, Algimantas Paulauskas

Folia Parasitologica 63:009 (2016) | DOI: 10.14411/fp.2016.009

Babesiosis is an emerging zoonotic disease and various wildlife species are reservoir hosts for zoonotic species of Babesia Starcovici, 1893. The objective of the present study was to investigate the presence and prevalence of Babesia spp. in moose Alces alces (Linnaeus) in two regions of Norway. A total of 99 spleen samples were collected from animals of various ages from an area with the occurrence of the tick Ixodes ricinus (Linnaeus, 1758), and from an area where the ticks are known to be absent. Infection was detected by the amplification of different regions of the 18S rRNA gene by using two different PCR primer sets...

A synoptic review of Promonobothrium Mackiewicz, 1968 (Cestoda: Caryophyllidea), parasites of suckers (Catostomidae) in North America, with description of two new species

Mikuláš Oros, Jan Brabec, Roman Kuchta, Anindo Choudhury, Tomáš Scholz

Folia Parasitologica 63:008 (2016) | DOI: 10.14411/fp.2016.008

Monozoic cestodes of the recently amended genus Promonobothrium Mackiewicz, 1968 (Cestoda: Caryophyllidea), parasites of suckers (Cypriniformes: Catostomidae) in North America, are reviewed, with information on their host specificity, distribution and data on the scolex morphology of seven species studied for the first time using scanning electron microscopy (SEM). Evaluation of type and voucher specimens from museum collections and newly collected material of most species indicated the following valid nominal species: Promonobothrium minytremi Mackiewicz, 1968 (type species); P. ingens (Hunter, 1927); P. hunteri...

A new species of Paraberrapex Jensen, 2001 (Cestoda: Lecanicephalidea) from Squatina guggenheim Marini (Squatiniformes: Squatinidae) off Argentina

Leonardo D. Mutti, Verónica A. Ivanov

Folia Parasitologica 63:007 (2016) | DOI: 10.14411/fp.2016.007

Paraberrapex atlanticus sp. n. (Cestoda: Lecanicephalidea) is described from the spiral intestine of the angel shark Squatina guggenheim Marini from coastal waters off Buenos Aires Province, Argentina. Paraberrapex atlanticus sp. n. can be distinguished from the only species described in the genus, P. manifestus Jensen, 2001 in having cocoons 5-6 times longer with more eggs per cocoon, the extension of the uterine duct, the distribution of vitelline follicles, and the size and density of microtriches on the bothridial surfaces. The presence of P. atlanticus sp. n. in S. guggenheim confirms the specificity of Paraberrapex...

Two new species of Euryhaliotrema Kritsky et Boeger, 2002 (Monogenea: Dactylogyridae) from Lutjanus russellii (Bleeker) and L. argentimaculatus (Forsskål) (Teleostei: Lutjanidae) in the South China Sea

Andre V. Bochkov

Folia Parasitologica 63:005 (2016) | DOI: 10.14411/fp.2016.005

A new mite species Schizocoptes daberti sp. n. (Acariformes: Chirodiscidae) from Chrysochloris stuhlmanni Matsche (Afrosoricida: Chrysochloridae) from the Democratic Republic of the Congo is described. It differs from the closely related species S. conjugatus Lawrence, 1944 in both sexes by distance si-si at least twice longer than si-se (vs these distances are subequal in S. conjugatus); in females by setae cp 30-40 µm long (vs about 65 µm long), and in males by the very weakly sclerotised posterior parts of the hysteronotal shield (vs strongly sclerotised),...

Seasonal occurrence and microhabitat specificity of Paradiplozoon ichthyoxanthon Avenant-Oldewage in Avenant-Oldewage et al., 2014 (Monogenea: Diplozoidae) infecting Labeobarbus aeneus (Burchell) (Teleostei: Cyprinidae) from the Vaal Dam, South Africa: water quality and host size as determining factors?

Beric M. Gilbert, Annemariè Avenant-Oldewage

Folia Parasitologica 63:004 (2016) | DOI: 10.14411/fp.2016.004

This is the first study detailing the microhabitat specificity of the monogenean parasite, Paradiplozoon ichthyoxanthon Avenant-Oldewage in Avenant-Oldewage et al., 2014. Samples of the monogenean were collected from the gills of the smallmouth yellowfish Labeobarbus aeneus (Burchell) from the Vaal Dam, South Africa, over four seasons with the use of gill nets. Host condition factor fluctuated between the different seasons, with the highest values recorded in summer. Adults and diporpas of P. ichthyoxanthon were found in all four seasons. Adult parasites predominantly infect the first gill arch, whereas diporpas were...

Folia Parasitologica 63:003 (2016) | DOI: 10.14411/fp.2016.003

A total of 269 faecal samples of various game animals, including 136 red deer (Cervus elaphus Linnaeus), 64 European fallow deer (Dama dama [Linnaeus]), 26 white-tailed deer (Odocoileus virginianus [Zimmermann]), and 43 mouflon sheep (Ovis orientalis musimon Pallas) were collected at 15 game preserves across the Czech Republic and examined for infection with species of Cryptosporidium Tyzzer, 1910 using microscopy (following aniline-carbol-methyl violet staining) and molecular tools. Oocysts of Cryptosporidium spp. were detected in one faecal sample originating from red deer. Ten positive cases of infection...

Molecular phylogenetic confirmation of Gnathostoma spinigerum Owen, 1836 (Nematoda: Gnathostomatidae) in Laos and Thailand

Jurairat Jongthawin, Pewpan M. Intapan, Oranuch Sanpool, Penchom Janwan, Lakkhana Sadaow, Tongjit Thanchomnang, Sakhone Laymanivong, Wanchai Maleewong

Folia Parasitologica 63:002 (2016) | DOI: 10.14411/fp.2016.002

We report the molecular-phylogenetic identification of larvae of the nematode genus Gnathostoma Owen, 1836 collected from a snake, Ptyas koros Schlegel, in Laos and adult worms from the stomach of a dog in Thailand. DNA was extracted and amplified targeting the partial cox1 gene and the ITS-2 region of ribosomal DNA. Phylogenetic analyses indicated that all five advanced third-stage larvae and seven adult worms were Gnathostoma spinigerum Owen, 1836. This is also the first molecular evidence of infection with G. spinigerum in a snake from Laos.

Ceratomyxa bohari sp. n. (Myxozoa: Ceratomyxidae) from the gall bladder of Lutjanus bohar Forsskål from the Red Sea coast off Saudi Arabia: morphology, seasonality and SSU rDNA sequence

Lamjed Mansour, Abdel-Azeem S. Abdel-Baki, Ahmad F. Tamihi, Saleh Al-Quraishy

Folia Parasitologica 63:001 (2016) | DOI: 10.14411/fp.2016.001

A new myxozoan, Ceratomyxa bohari sp. n., infecting the gall bladder of two-spot red snapper, Lutjanus bohar Forsskål, in the Red Sea off Saudi Arabia, is described using light microscopy and characterised genetically. The infection was recorded as mature spores floating free in the bile. The overall prevalence of infection of the type host was 19% (67 fish infected of 360 examined), with the highest prevalence in autumn (31%; 28/90) and the lowest in winter at 12% (11/90). Mature spores are slender and slightly crescent-shaped in the frontal view, with anterior and posterior margins tapered gradually to rounded valvular tips. Spore...

Self-sustaining infrapopulation or colony? Redial clonal groups of Himasthla elongata (Mehlis, 1831) (Trematoda: Echinostomatidae) in Littorina littorea (Linnaeus) (Gastropoda: Littorinidae) do not support the concept of eusocial colonies in trematodes

Kirill V. Galaktionov, Irina M. Podvyaznaya, Kirill E. Nikolaev, Ivan A. Levakin

Folia Parasitologica 62:067 (2015) | DOI: 10.14411/fp.2015.067

Trematode sporocysts and rediae reproduce by parthenogenesis, forming clonal groups in the molluscan host. It has recently become popular to consider these groups as eusocial colonies, with division of labour between rediae morphs: small 'soldiers' incapable of reproduction defend the colony, while large rediae reproduce. Alternatively, clonal groups can be considered as self-sustaining infrapopulations. We tested these two hypotheses in the light of new data on rediae of Himasthla elongata (Mehlis, 1831) from snails Littorina littorea (Linnaeus) concerning ultrastructure, growth character and composition of their groups. Clonal groups...

Tuncay Çelik, Cem Gökçen, Özgür Aytaş, Aysima Özçelik, Mustafa Çelik, Nurdan Çoban

Folia Parasitologica 62:066 (2015) | DOI: 10.14411/fp.2015.066

The purpose of this study was to investigate the possible relationship between Toxoplasma gondii (Nicolle et Manceaux, 1908) and stuttering. We investigated the seropositivity rate for anti-T. gondii IgG and antibodies by enzyme-linked immunosorbent assay (ELISA) in stuttering children to ascertain a possible relationship between T. gondii infection and stuttering. We selected 65 stuttering children and 65 control children (non-stutterers) to investigate the seropositivity rate of anti-T. gondii antibodies by ELISA. Cranial magnetic resonance imaging (MRI) and scalp electroencephalography (EEG) were also performed in stuttering...

Evaluating the role of intestinal parasites in the high rates of irritable bowel syndrome in South America: a pilot study

George Vasquez-Rios, Jorge D. Machicado, Maria T. Gamero, Adriana Pezua, Angel B. Betancourt, Angelica Terashima, Luis A. Marcos

Folia Parasitologica 62:065 (2015) | DOI: 10.14411/fp.2015.065

There is limited data on the role of intestinal parasites in irritable bowel syndrome (IBS) in South America. We evaluated the association between intestinal parasitism and IBS status in Peru. Intestinal parasites were detected in 43% of the IBS cases and in 51% of the controls (P = 0.4). After excluding those infected by any parasite, the IBS prevalence remained high (22%; P = 0.7). No statistically significant difference was noted between IBS cases and controls in terms of monoparasitism, biparasitism or multiparasitism. Furthermore, the protist Blastocystis sp. was inversely associated with IBS.

Presence of potential pathogenic genotypes of free-living amoebae isolated from sandboxes in children's playgrounds

Marcin Cholewiński, Piotr Solarczyk, Monika Derda, Agnieszka Wojtkowiak-Giera, Edward Hadaś

Folia Parasitologica 62:064 (2015) | DOI: 10.14411/fp.2015.064

Some free-living amoebae are a potential threat to human health. The best known species are those of the genus Acanthamoeba Volkonsky, 1931, which cause Acanthamoeba keratitis, granulomatous amoebic encephalitis and other forms of tissue inflammation. The aim of the present study was to search for potential pathogenic genotypes of free-living amoeba in the sand in children's playgrounds. Our results confirmed that free-living amoebae were present in all examined playgrounds. Sequences of the 18S rDNA have shown that all isolated potentially pathogenic strains of amoebae belong to genotype T4 of Acanthamoeba. The potential...

How many species of whipworms do we share? Whipworms from man and other primates form two phylogenetic lineages

Jana Doležalová, Miroslav Oborník, Eva Hajdušková, Milan Jirků, Klára J. Petrželková, Petra Bolechová, Cristina Cutillas, Rocio Callejón, Jozef Jaroš, Zuzana Beránková, David Modrý

Folia Parasitologica 62:063 (2015) | DOI: 10.14411/fp.2015.063

The whipworms, i.e. parasitic nematodes of the genus Trichuris Roederer, 1761, infect a variety of mammals. Apparently low diversity of primate-infecting species of Trichuris strongly contrasts with the high number of species described in other mammalian hosts. The present study addresses the diversity of whipworms in captive and free-ranging primates and humans by analysing nuclear (18S rRNA, ITS2) and mitochondrial (cox1) DNA. Phylogenetic analyses revealed that primate whipworms form two independent lineages: (i) the Trichuris trichiura (Linnaeus, 1771) clade comprised of genetically almost identical whipworms from human...

Multilocus genotyping of Giardia duodenalis (Lambl, 1859) from symptomatic human infections in Slovenia

Barbara Šoba, Sabina Islamović, Miha Skvarč, Simone M. Cacciò

Folia Parasitologica 62:062 (2015) | DOI: 10.14411/fp.2015.062

Giardiasis is a common gastrointestinal infection of humans and animals with a worldwide distribution. Eight genetic groups (known as assemblages A to H) are currently recognised within the species complex of Giardia duodenalis (Lambl, 1859), of which assemblages A and B are responsible for infection of humans and other mammalian hosts. Genotyping data on giardiasis are not available from Slovenia. In this work, we have characterised isolates of G. duodenalis from 85 human symptomatic cases collected during 2002-2013. Genomic DNAs were first tested by a real-time (rt) PCR assay and then by conventional PCR at three loci (beta-giardin,...

Sexual segregation of Echinorhynchus borealis von Linstow, 1901 (Acanthocephala) in the gut of burbot (Lota lota Linnaeus)

Arto Tuomainen, E. Tellervo Valtonen, Daniel P. Benesh

Folia Parasitologica 62:061 (2015) | DOI: 10.14411/fp.2015.061

Helminths often occupy defined niches in the gut of their definitive hosts. In the dioecious acanthocephalans, adult males and females usually have similar gut distributions, but sexual site segregation has been reported in at least some species. We studied the intestinal distribution of the acanthocephalan Echinorhynchus borealis von Linstow, 1901 (syn. of E. cinctulus Porta, 1905) in its definitive host, burbot (Lota lota Linnaeus). Over 80% of female worms were found in the pyloric caeca, whereas the majority of males were in the anterior two-thirds of the intestine. This difference was relatively consistent between individual...

Influence of life history traits on the population genetic structure of parasitic helminths: a minireview

Severo Vázquez-Prieto, Román Vilas, Esperanza Paniagua, Florencio M. Ubeira

Folia Parasitologica 62:060 (2015) | DOI: 10.14411/fp.2015.060

Parasite life history traits influence the rate of gene flow between populations and the effective population size, both of which determine the levels of genetic variability and the geographic distribution of such variability. In this short review targeted to parasitologists, we summarise how life history traits influence the population genetic structure of parasitic helminths. These organisms are characterised by a wide variety of life cycles and are ecologically different from microparasites, which have been studied in more detail. In order to provide the reader a concise review that illustrates key aspects of the subject matter, we have limited...

During investigations of gill ectoparasites (Platyhelminthes) parasitising freshwater fish from Central America (Guatemala, Honduras, El Salvador and Panama) and southeastern Mexico (Guerrero, Oaxaca and Chiapas), the following dactylogyrid monogenoidean were found: Urocleidoides simonae sp. n. from Profundulus punctatus (Günther) (type host), Profundulus balsanus Ahl, Profundulus guatemalensis (Günther), Profundulus kreiseri Matamoros, Shaefer, Hernández et Chakrabarty, Profundulus labialis (Günther), Profundulus oaxacae (Meek), Profundulus sp. 1 and Profundulus sp. 2 (all Profundulidae);...

Trypanorhynch cestodes (Eutetrarhynchidae) from batoids along the coast of Argentina, including the description of new species in Dollfusiella Campbell et Beveridge, 1994 and Mecistobothrium Heinz et Dailey, 1974

Adriana Menoret, Verónica A. Ivanov

Folia Parasitologica 62:058 (2015) | DOI: 10.14411/fp.2015.058

During a recent parasitological survey of elasmobranchs along the coast of Argentina, two new species of eutetrarhynchid cestodes of the genera Dollfusiella Campbell et Beveridge, 1994 and Mecistobothrium Heinz et Dailey, 1974 were collected from batoids. Dollfusiella acuta sp. n. was found in four arhynchobatid skates, i.e. Sympterygia acuta Garman (type host), Sympterygia bonapartii Müller et Henle, Atlantoraja castelnaui (Miranda Ribeiro) and Atlantoraja platana (Günther), and Mecistobothrium oblongum sp. n. in the eagle ray Myliobatis goodei Garman. Dollfusiella...

Rhinebothrium jaimei sp. n. (Eucestoda: Rhinebothriidea: Rhinebothriidae): a new species from Neotropical freshwater stingrays (Potamotrygonidae)

Fernando P. L. Marques, Florian B. Reyda

Folia Parasitologica 62:057 (2015) | DOI: 10.14411/fp.2015.057

Neotropical freshwater stingrays (Batoidea: Potamotrygonidae) host a diversity of parasites, including some, like their hosts, that are marine-derived. Among the parasites of potamotrygonids, the cestode fauna is the most diverse, with multiple genera having been reported, including genera endemic to the freshwaters of the Neotropics and genera that have cosmopolitan distributions. Recent efforts have been made to document the diversity of cestodes of this host-parasite system and to refine the taxonomy of parasite lineages. The present study contributes to our knowledge of Rhinebothrium Linton, 1890, a diverse cosmopolitan genus of rhinebothriidean...

An elevated blood glucose level and increased incidence of gestational diabetes mellitus in pregnant women with latent toxoplasmosis

Šárka Kaňková, Jaroslav Flegr, Pavel Calda

Folia Parasitologica 62:056 (2015) | DOI: 10.14411/fp.2015.056

About 30-50% of the world human population are infected with the protozoan parasite Toxoplasma gondii (Nicolle et Manceaux, 1908). Latent toxoplasmosis has many specific behavioural and physiological effects on the human body and influences the course of pregnancy, including secondary sex ratio of children of infected mothers. It was suggested that an increased concentration of glucose could be the proximate cause of increased sex ratio. There are some indirect indications of possible association between toxoplasmosis and certain forms of diabetes. Here we searched for a possible link between latent toxoplasmosis and the level of glucose in...

The aim of the present work was to determine whether Dermacentor reticulatus (Fabricius), tick species common in eastern Poland could be infected with Toxoplasma gondii (Nicolle et Manceaux, 1908). A total of 664 unfed D. reticulatus ticks were collected from six localities of Lublin province (eastern Poland) within the framework of study for the presence of bacterial, viral and parasitological infections, with use of PCR and confirmed by sequencing analysis. The prevalence of T. gondii DNA of B1 gene in the total examined D. reticulatus ticks was 3.2%. The infection varies greatly depending on the locality of tick...

Caligus brevicaudatus Scott, 1901, a common but poorly known species of parasitic copepod, is redescribed from newly collected specimens of both sexes. The new material was collected from the body surface of tub gurnards, Chelidonichthys lucerna (Linnaeus), caught in eastern Mediterranean waters off the Turkish coast. Inadequately described female structures from earlier descriptions are redescribed and illustrated in detail and the male of C. brevicaudatus is described for the first time. The new material of C. brevicaudatus is compared with material collected by A. Scott and stored in the collections of the Natural History Museum,...
