In the present study, we successfully amplified the 28S ribosomal DNA of 3 species of the Psilotrema genus (Psilotrema oschmarini Besprozvannykh, 2007, P. acutirostris Oschmarin, 1963 and P. simillimum Muhling, 1989) from the Russian Far East. The genetic divergence between these species was estimated, and the phylogenetic relationships of the Psilotrema genus and the Psilostomatidae family wer...

The identification of parasites from ancient cultures expands our list of parasites infective to extant humans. A partially mummified human body from the archeological site of Lapa do Boquete, Minas Gerais State, Brazil, was recently discovered. It was interred between 600 and 1,200 yr ago. Dietary analysis showed that the mummified body was from a society that had a mixed subsistence of agricu...

The following acanthocolpid species are reported from New Caledonia. Acaenodera nautili sp. n. from Conger cinereus Rüppel differs from other Acaenodera species in details of the body-spination, the sucker-ratio and the bipartite seminal vesicle; Stephanostomum murielae sp. n. from Carangoides hedlandensis (Whitley) differs from most species of Stephanostomum in the average of 36 circum-oral sp...

Several dozens of small trematodes were found in the small intestine of a Japanese monkey, Macaca fuscata, that was captured in Sendai City, Miyagi Prefecture, Japan. The trematode was identified as Ogmocotyle ailuri. This is the first case of a Japanese monkey infected with Ogmocotyle trematodes, and a new host record for O. ailuri.

During a regular veterinary inspection of fishes from Lake Balaton, Hungary, echinostomatid metacercariae (Digenea), with collar spines characteristic of species of the genera Petasiger Dietz, 1909 and Paryphostomum Dietz, 1909, were found in the lateral line scales of a roach Rutilus rutilus (Linnaeus), an apparently unique site. In a subsequent examination of 586 fishes from 20 different spec...

A large-scale molecular survey of Clinostomum (Digenea, Clinostomidae). —Zoologica Scripta, 44, 203–217. Members of the genus Clinostomum Leidy, 1856 are parasites that mature in birds, with occasional reports in humans. Because morphological characters for r...

A survey of the parasites of Indo-West Pacific Haemulidae revealed the presence of three new cryptogonimid (Digenea: Cryptogonimidae) species warranting two new genera, Beluesca littlewoodi n. gen., n. sp. and B. longicolla n. sp. from the intestine and pyloric caeca of Plectorhinchus gibbosus and Chelediadema marjoriae n. gen., n. sp. from the intestine and pyloric caeca of Diagramma labiosum,...

Monitoring studies of the species diversity in marine ecosystems provide important data on ecological changes caused by global warming and anthropogenic influence. The present work was aimed to analyze helminths parasitic teleost fishes inhabiting area near Ukrainian Antarctic Station “Akademik Vernadsky” (Galindez Island, Argentine Islands, West Antarctica). During April–January 2014–2015 2019...

An unnamed microcercous cercaria (Digenea: Monorchiidae), a parasite of Amiantis purpurata (Lamarck, 1818) (Bivalvia: Veneridae) and its corresponding metacercaria from the province of Buenos Aires and the Patagonian coast of the Southwest Atlantic Ocean, are described. The cercaria described in this paper differs from the three other monorchiid microcercous cercariae, i.e., Lasiotocus minutus ...

The maintenance of strict host specificity by parasites when several closely related host species live in sympatry is poorly understood. Species of intertidal trochid snails in the genera Diloma, Melagraphia and Austrocochlea often occur together and are parasitised by a single digenean morphotype (Platyhelminthes, Trematoda), tentatively placed in Opecoelidae. Of the 10 trochid species (6 from...
