First report of Ascarophis Van Beneden, 1871: A. Brasiliensis n.sp. (Nematoda, Ascarophidinae) and Procamallanus (Spirocamallanus) Pereira/Annereaux, 1946 (Nematoda, Procamallaninae) in South America

Ascarophis brasiliensis recovered from the stomach of Trachinotus carolinus (L. 1766), is proposed as a new species and Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 is redescribed from a new host: Paralonchurus brasiliensis (Steind., 1875). A. brasiliensis is more closely related to A. crassicolis Dollfus & Campana-Rouget, 1956, from which it differs mainly by the absence of cervical cuticular expansion and size of the eggs. The new species is also compared to A. cooperi johnston & Mawson, 1945 and A. girellae (Yamaguti, 1935) Campana-rouget, 1955. The validity of the proposed species is discussed.

Adults and nymphs of Cavernicola lenti, new species, from Amazonas state, Brazil, are described and illustrated. Observations on the biology of the new species are presented. Preliminaty findings indicate that C. lenti is a probable vector of bat trypanosomes.

Nematodes of Amazonian birds, with a description of Hoazinstrongylus amazonensis n.gen.n.sp. (Trichostrongylidae, Libyostrongylinae)

During recent studies of the parasites of birds from the Amazonian Regio, the following nematodes were recovered: Hoazinstrongylus amazonensis n.gen.n.sp. from Opisthocomus hoazin (Muller, 1776); Ascaridia columbae (Gmel., 1790) Travassos, 1913, from Leptotila r. rufaxilla (Richard & Bernard, 1712) representing a new host record; Inglisakis ibanezi Freitas, Vicente & Santos, 1969, Cyrnea (C.) semilunaris (Molin, 1860) Seurat, 1914 and Thelazia digitata Travassos, 1918.

Helminths parasites of freshwater fishes from Pirassununga, SP, Brazil

Twelve species of parasitic helminths, seven trematodes, four nematodes and one acanthocephalan are reported from various hosts. Creptotrema lynchi, a parasite from Bufo marinus in Colombia, is described for the first time in fish and from Brazil, parasitizing two different species. A list of the host species, measurements and figures of most parasites are included with particular reference to the tegument of Bellumcorpus major recovered from a new host. The genus Zonocotyloides Padilha, 1978 is considered a synonym of Zonocotyle and the new combination: Zonocotyle haroltravassosi is proposed to the species Zonocotyloides haroltravassosi Padilha, 1978. The nematodes Cucullanus pinnai and Procamallanus (Spirocamallanus) inopinatus and the trematode Pararhipidocotyle jeffersoni are reported in new hosts. The description of the acanthocephalan Neoechinorhynchus curemais (new locality record) is supplemented. Other parasites recovered include the nematodes Travnema travnema (new locality record), Rondonia rondoni and the digenetic trematodes Cladocystis intestinalis, Pseudosellacotyla lutzi (new locality record), Teratotrema sp. and Zonocotyle bicaecata.

Saccocoelioides godoyi n.sp. (Haploporidae) and other trematodes parasites of fishes from the Guaiba estuary, RS, Brazil

One hundred and fourteen specimens of eleven different species of freshwater fishes from the Guaiba estuary, were examined for digenetic flukes. Saccocoelioides godoyi n.sp. proposed herein, is closest to S. magniovatus and to S. szidati; S. magniovatus is much smaller with comparably larger eggs and S. szidati has larger hermaphroditic sac and considerably larger testis. Creptotrema creptotrema is referred to a new host; Acanthostomum gnerii, Crepidostomum platense, Eocreadium intermedium (immature form), Parspina argentinensis and Zonocotyle bicaecata are reported. This paper confirms the similatary between the parasites of freshwater fishes from Argentina and Brazil. Measurements and original figures of all species are given.

Bolivian phlebotomines. II Psychodopygus Yucumensis n.sp., a new man-biting phlebotomine sandfly from subandean region (Diptera, Psychodidae)

Psychodopygus yucumensis n.sp., a new species of Phlebotomine sandfly belonging in genus Psychodopygus mang., is described from specimens collected from human bait, in Beni dept., Bolivia. The male is characteristic of the series panamensis, but the female, closely related to P. carrerai carrerai, can be confused with this species ("cryptic species"). Isozyme characterization can determine any specimen of either species, while morphometric analysis shows statistical differences between the two species. P. yucumensis is strongly anthropophilic. A Leishmania braziliensis braziliensis stock was isolated from this new species, indicating that it is one of the vectors of mucocutaneous Leishmaniasis in the lowland subandean area.
