A tylenchid nematode parasite of a male long-legged fly, Tachytrechus sanus Osten Sacken (Diptera: Dolichopodidae) from Montana, USA is described as Parasitylenchus myiophagus n. sp. (Nematoda: Parasitylenchidae). The new species is characterized by the presence of an extremely long first generation female and numerous short and wide second generation males and females produced in “enclosed” clusters in the host’s body cavity. Both generation female nematodes are ovoviviparous, with short stylets lacking knobs and simple tails lacking spikes, palps or mucrons. The second generation males have paired, separate spicules, short stylets, and a bursa but no visible gubernaculum. The fly host shows evidence of demasculinization, which is attributed to nematode parasitism. The gonads of the second generation adults are infected with a microsporidium (Microsporidia), which is a new host record for tylenchid nematodes. A tylenchid-infected Baltic amber dolichopodid shows that associations between these two organisms extend back at least to the Eocene.

AbstractIn total, 2097 individuals of Trachelipus squamuliger and 20 individuals of Armadillidium vulgare from four habitats (three woodland sites and one pasture) in the region of Stara Zagora, Bulgaria, were examined for the presence of cystacanths of Plagiorhynchus cylindraceus, a common acanthocephalan parasite of passerine birds. In T. squamuliger from woodland habitats, cystacanths were found with prevalence 4.0–9.3%, intensity 1–5 (mean 1.22–1.57) and mean abundance 0.057–0.113. No significant differences were observed between infections in males and females of T. squamuliger. None of the T. squamuliger individuals from the pasture examined was infected. Out of 48 infected females of T. squamuliger, only one had developed eggs (in agreement with previous studies revealing the negative effect of the cystacanths on the development of female gonads of woodlice). One individual of A. vulgare was infected with a single cystacanth. The occurrence of P. cylindraceus in T. squamuliger is a new host record.

Arapaima Gigas

AbstractFemale specimens of a little-known philometrid nematode, Nilonema senticosum (Baylis, 1927), were collected from the swimbladder of the arapaima, Arapaima gigas, from the Amazon River basin (Iquitos, Loreto District) in Peru. Scanning electron microscopical (SEM) examination, used for the first time in this species, made it possible to reveal some taxonomically important, previously unreported features of N. senticosum, such as the presence of minute cephalic papillae (10 papillae in 2 circles) and amphids surrounding the small oral aperture, and to confirm the absence of an anal opening in this species. Males and females of another philometrid, Alinema amazonicum (Travassos, 1960), were recovered from the body cavity of the pimelodid catfishes Calophysus macropterus and Brachyplatystoma juruense (a new host record) from the Amazon River basin (fish market in Iquitos, Loreto District) in Peru. SEM examination, not previously used in the male of A. amazonicum, enabled to study in detail the male cephalic and caudal structures.

Meteterakis Singaporensis

AbstractOswaldofilaria acanthosauri sp. nov. from the body cavity of the Cardamom Mountain horned agamid, Acanthosaura cardamomensis (Sauria: Agamidae), collected in Pursat Province, Cambodia is described. Of the 14 species assigned to Oswaldofilaria, O. acanthosauri sp. nov. is most similar to those species with spicular ratio of less than 2, namely, O. brevicaudata and O. chlamydosauri. Oswaldofilaria acanthosauri sp. nov. is easily separated from these 2 species in that O. brevicaudata is a South American species and in O. chlamydosauri the distal ends of the spicules are pointed not blunt. Mature individuals of 2 additional species of Nematoda, Meteterakis singaporensis and Orneoascaris sandoshami, as well as larvae assignable to Ascariidae were found. Acanthosaura cardamomensis represents a new host record for Meteterakis singaporensis, Orneoascaris sandoshami and Ascariidae (larvae).

A novel species, Micropeltis goniothalamicola and a new record Scolecopeltidium menglaense were collected from Mae Fah Luang Botanical Gardens, Thailand. Our new taxon is different from other species in Micropeltis in having relatively smaller ascomata, 6–8-spored asci and 4–5-septate ascospores covering with mucilaginous sheath. Our new record, S. menglaense is the first host recorded from Jasmine grandiflorum (Oleaceae). Morphological comparison coupled with phylogenetic analysis of combined LSU and ITS sequence data provide evidence for the new species and new host record.

Rhipidocotyle pentagonum (Ozaki, 1924) is reported for the first time in South America parasitizing Auxis thazard and in a new host Katsuwonus pelamis. Tergestia laticollis (Rudolphi, 1819) is reported for the first time in South America and in Thunnus albacares, representing a new host record. Copiatestes filiferus (Leuckart, in Sars, 1885) is recorded for the first time in Brazil and in Thunnus albacares, another new host record. Tetrochetus coryphaenae (Yamaguti, 1934) is presented for the first time in Brazil parasitizing Thunnus albacares.
