Abstract: In 1985, Amin presented a new system for the classification of the Acanthocephala in Crompton and Nickol's (1985) book 'Biology of the Acanthocephala' and recognized the concepts of Meyer (1931, 1932, 1933) and Van Cleave (1936, 1941, 1947, 1948, 1949, 1951, 1952). This system became the standard for the taxonomy of this group and remains so to date. Many changes have taken place and many new genera and species, as well as higher taxa, have been described since. An updated version of the 1985 scheme incorporating new concepts in molecular taxonomy, gene sequencing and phylogenetic studies is presented. The hierarchy has undergone a total...

Folia Parasitologica 60 306-320 (2013) | DOI: 10.14411/fp.2013.032
Abstract: Three new species of dicyemid mesozoans are described for the first time from Australian octopus and cuttlefish species. Dicyemennea floscephalum sp. n. is described from Octopus berrima Stranks et Norman (southern keeled octopus) collected from Spencer Gulf and Gulf St. Vincent, South Australia, Australia and represents the first description of a species of Dicyemennea Whitman, 1883 from Australian waters. Dicyema papuceum sp. n. and D. furuyi sp. n. are described from Sepia papuensis Hoyle (Papuan cuttlefish) collected from Shark Bay, Western Australia, Australia. Dicyemennea floscephalum...
Two new species of Halysioncum Caira, Marques, Jensen, Kuchta et Ivanov, 2013 (Cestoda, Diphyllidea) from Indo-Pacific rays of the genus Aetomylaeus Garman (Myliobatiformes, Myliobatidae)

Abstract: Recent collections of cestode parasites from two species of the myliobatid genus Aetomylaeus Garman from several localities in the Pacific Ocean resulted in the discovery of two new species of Halysioncum Caira, Marques, Jensen, Kuchta et Ivanov, 2013. Halysioncum gibsoni sp. n. from Aetomylaeus maculatus (Gray) in the South China Sea off Borneo differs from all of its congeners in having the following combination of characters: 27 apical hooks (14 type A and 13 type B hooks), 11-12 lateral hooklets, 22-28 spines per column on the cephalic peduncle, testes distributed in a single column and an internal seminal...
Digenean parasites of the great antshrike, Taraba major (Aves: Thamnophilidae), from Argentina, with a description of a new species of the genus Strigea (Strigeidae)

Folia Parasitologica 60 331-338 (2013) | DOI: 10.14411/fp.2013.034
Abstract: During a survey of birds from Argentina, two species of Digenea, one of them new, were found parasitizing the great antshrike, Taraba major (Vieillot) (Aves: Thamnophilidae). The strigeid, Strigea orbiculata sp. n. is characterized by having a body plump, a copulatory bursa without a membraneous fold ('Ringnapf'), entire testes, eggs with miracidia with eye-spots, by the arrangement of vitelline follicles in the forebody, which are densely distributed from its anterior edge, and by the absence of a neck region in the hindbody. Among the known Neotropical species of Strigea Abildgaard, 1790, only five share with...
Two new species of Cylicospirura Vevers, 1922 (Nematoda: Spirocercidae) from carnivores in southern Africa, with validation of the related genera Gastronodus Singh, 1934 and Skrjabinocercina Matschulsky, 1952

Abstract: Two new species of Cylicospirura Vevers, 1922 are described from carnivores from southern Africa. Cylicospirura crocutae Junker et Mutafchiev sp. n. from Crocuta crocuta (Erxleben) in Zimbabwe is distinguished from its congeners by combinations of characters, including the presence of four cephalic and four external labial papillae, while internal labial papillae were not distinct, the presence of groups of small accessory teeth between the six large tricuspid teeth, the fifth and the sixth pairs of the caudal papillae being equidistant from the cloaca, and a large ratio of length of the muscular oesophagus to that of...
Huffmanela markgracei sp. n. (Nematoda: Trichosomoididae) from buccal cavity of Atlantic sharpnose shark, Rhizoprionodon terraenovae (Carcharhiniformes: Carcharhinidae), in the northwestern Gulf of Mexico off Texas

Folia Parasitologica 60 353-358 (2013) | DOI: 10.14411/fp.2013.036
Abstract: Eggs of Huffmanela markgracei sp. n. infected one of three Atlantic sharpnose sharks, Rhizoprionodon terraenovae (Richardson) (Carcharhiniformes: Carcharhinidae) captured by bottom long-line in the northwestern Gulf of Mexico off Padre Island, Texas. Eggs in the skin formed sinuous tracks (1-8 eggs wide; 1-4 eggs deep; 150 eggs/mm2) occupying a swath of the skin 22 cm × 2 cm on the tongue, branchial arches and the dorsal surface of the buccal cavity. Eggs had transverse eggshell ridges (branching and non-branching), had shells that were clear, amber or brown, and measured 90-113 µm (x = 102...

Folia Parasitologica 60 359-364 (2013) | DOI: 10.14411/fp.2013.037
Abstract: A new species of parasitic copepod, Chondracanthus hoi sp. n. (Copepoda: Chondracanthidae), is described based on specimens of both sexes collected from the buccal cavity and gill arches of the silvery john dory, Zenopsis conchifer (Lowe) (Zeiformes: Zeidae), from waters off northern Argentina (35-36°S, 53-54°W). Female of C. hoi differs from its congeners by the following combination of characters: presence of five pairs of trunk processes, antennule with four knobs tipped with small setae and absence of denticles on the terminal process of maxilla. Chondracanthids and zeiform fishes have been proposed as an example...
A new species of Heterochondria (Copepoda: Chondracanthidae) parasitic on many-banded sole, Zebrias fasciatus (Pleuronectiformes: Soleidae) from Korea, with a key to the species of the genus
Seong Yong Moon, Ho Young Soh
Folia Parasitologica 60 365-371 (2013) | DOI: 10.14411/fp.2013.038
Abstract: A new species of Chondracanthidae (Copepoda: Cyclopoida), Heterochondria orientalis sp. n., is described based on specimens of both sexes collected from the gill rakers and the inner side of the operculum of the many-banded sole, Zebrias fasciatus (Basilewsky), from the Yellow Sea, Korea. The new species resembles most closely H. zebriae (Ho, Kim et Kuman, 2000), but can be distinguished from this species and other congeners by the shape of the trunk and length of the antenna, the number of teeth on the mandible and the terminal process of the maxilla, and the structure of the male antennule and maxilliped. Heterochondria...

Abstract: Therapeutic efficacy of sulfadoxine-pyrimethamine (SP), which is commonly used to treat falciparum malaria, was assessed in isolates of Plasmodium falciparum (Welch, 1897) and Plasmodium vivax (Grassi et Feletti, 1890) of Aligarh, Uttar Pradesh, North India and Taif, Saudi Arabia during 2011-2012. Both the species showed mutations in dihydrofolate reductase (DHFR) enzyme as they have common biochemical drug targets. Mutation rate for pfdhfr was higher compared to pvdhfr because the drug was mainly given to treat falciparum malaria. Since both the species coexist, P. vivax was also exposed to SP due to faulty species diagnosis...
