A New Species

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.

Summary Aphelenchoides kheirii n. sp. was isolated during a survey of nematodes associated with bark samples of pine trees (Pinus nigra) in West Azerbaijan province, north-western Iran. The new species has a body length of 500 (448-520) μm in the female and 442 (402-480) μm in the male. The cuticle is weakly annulated with four lateral lines and the lip region is offset. The stylet is 10.4 (10-11) μm long with small basal swellings and the excretory pore located immediately posterior to base of metacorpus; hemizonid invisible. The post-vulval uterine sac length 37.7 (28-45) μm. Spicules are relatively short (18-20 μm in dorsal limb) and the end of the dorsal limb clearly curved ventrally like a hook. The male tail has usual three pairs of caudal papillae (2 + 2 + 2) and a well-developed mucron. The female tail is conical, terminating in a complicated step-like projection, usually with many tiny nodular protuberances. The new species belongs to the Group 2 category of Aphelenchoides species sensu Shahina in which ten known species among Groups 2 and 4 sensu Shahina, namely: A. arcticus, A. blastophthorus, A. fuchsi, A. parasaprophilus, A. paraxui, A. xui, A. dactylocercus, A. gynotylurus, A. iranicus and A. saprophilus are the most similar species. Phylogenetic analysis based on small subunit (SSU) and partial large subunit (LSU) sequences of rRNA supported the morphological results.

Sterlet Acipenser Ruthenus

Abstract A new species, Skrjabinopsolus nudidorsalis sp. nov. is described from the sterlet Acipenser ruthenus, caught in the River Volga basin (Russia). This species differs from previously described congeners by the absence of vitelline follicles on the dorsal side of the body. The complete 18S rRNA and partial 28S rRNA gene sequences obtained for S. nudidorsalis are the first molecular data for the family Deropristidae. The results of phylogenetic analysis indicate that Deropristidae is sister to the Monorchiidae + Lissorchiidae group. The results of the phylogenetic study contradict the current taxonomic hypothesis that Deropristidae belongs to the superfamily Lepocreadioidea and allow inclusion of this family in Monorchioidea. The morphological similarity of deropristids to other monorchioids is recognizable from the presence of a bipartite internal seminal vesicle, spinous cirrus and a voluminous, armed metraterm.

A New Species

Summary A new species of pin nematode, Paratylenchus jasmineae sp. n., was isolated and described from the rhizosphere of jasmine in India. The new species can be diagnosed by having a relatively larger body length of 248-355 μm, stylet length of 24.6-28.5 μm, lateral field with four lateral lines, the presence of small post-vulval uterine sac and absence of advulval flaps in the females. Additional morphological characters included continuous lip region with small projected submedian lobes, large and oblong-shaped spermatheca, the presence of prevulval swelling, and arcuate conoid tail with finely rounded terminus. Molecular characterisation of the species was carried out based on internal transcribed spacer sequence (ITS rRNA) and D2-D3 expansion segment of 28S rRNA subunit. Phylogenetic analyses based on ITS and D2-D3 molecular markers resulted in clear separation of P. jasmineae sp. n. from other Paratylenchus species.
