Aoruroides chubudaigaku n. sp. (Nematoda: Oxyuridomorpha: Thelastomatidae) is described from the wood-burrowing cockroach Panesthia angustipennis spadica (Shiraki, 1906) (Blattodea: Blaberidae: Panesthiinae) from Aichi prefecture, Japan. Females of A. chubudaigaku n. sp. are similar to A. costaricensis Carreno & Tuhela, 2011 by the position of the nerve ring at level of the first third of the isthmus, the body length and the comparative measurements of the oesophagus and tail. They differ by the position of the excretory pore and the vulva. The males of A. chubudaigaku n. sp. are characterized by the absence of ornamentations in the cervical cuticle and the nerve ring located at the posterior third of the corpus. In addition, the males of the new species can be differentiated by the length of the body and the comparative lengths of the oesophagus and the tail. The phylogeny of A. chubudaigaku n. sp. is inferred by the D2-D3 domains of the LSU rDNA and the validity of the genus Aoruroides Travassos & Kloss, 1958 is discussed on the basis of both molecular and morphological data. This constitutes the first species of the genus Aoruroides described from the Japanese archipelago.

A New Species

During a survey of soil nematodes in Iran, a new species of Ditylenchus Filipjev, 1936 was discovered. Ditylenchus sarvarae sp. n. is characterised by its body length (1.0–1.4 mm), lateral field with seven incisures and without areolation, long postuterine sac (1.8–2.8 times the corresponding body diameter) and conical female tail with pointed tip (68–89 μm long, c = 13.7–18.2, c' = 4.2–5.1). Male specimens have conical tails (64–70 μm long, c = 14.5–16.7, c' = 4.0–4.5), spicules (22–26 μm long) and gubernaculum (8–10 μm long). Measurements and illustrations are provided for this new species. A molecular study of the 28S rDNA region of D. sarvarae sp. n. demonstrates that the Iranian species belongs to a separate group compared with the other molecularly characterized species of genus Ditylenchus.

A New Species

AbstractA new species of Skrjabinolecithum (Digenea: Waretrematinae), Skrjabinolecithum pyriforme n. sp., has been found in the intestines of Liza haematocheila and Mugil cephalus from the Primorsky Region, Russia. These worms differ from S. vitellosum and S. lobolecithum by the presence of two caeca, as do S. spasskii, S. indicum and S. bengalensis. These species differ morphologically from S. pyriforme n. sp. by a number of features, including body width, oral sucker, pharynx, eggs and ratio of length and width of the body. The most similar species to S. pyriforme n. sp. is Platydidymus flecterotestis (Zhukov, 1971) with some differences in maximal body length, testis and egg sizes. The results of molecular analysis confirmed that this new species belongs to Skrjabinolecithum on the basis of close relationships with S. spasskii-type species.

A New Species

The first finding of the genus Greeffiella Cobb 1922 (Greeffiellinae, Desmoscolecidae) in the Black Sea is presented. Two mature females were collected in Northwestern Shelf of Crimea in strongly silted fine sand with detritus at a water depth of 56 m. Greeffiella sp. is described and illustrated. The absence of males in the collections does not allow the authors to present it as a new species for science or to identify it as one of the known species of the genus Greeffiella. Black sea specimen is distinguished from the other known species of the genus Greeffiella with the presence of 8 pairs of thicker specific setae along the body, the basis of which looks like a small lamina, but without hairs, which was previously described for G. pierri Schrage & Gerlach, 1975 and G. australis Schrage & Gerlach, 1975. The short esophagus at the base has two salivary glands and a cardia. Cardia has not been mentioned before for the known species of the genus Greeffiella.

In this paper we describe a new genus and a new species of Chiridotidae based on specimens collected in shallow water off the South-eastern Brazilian coast. Gymnopipina ikamiaba gen. nov. et sp. nov. is characterized by the complete absence of dermal ossicles in the body, and it differs from the other ossicleless apodids in the number of tentacles and of Polian vesicles, and in the morphology of the calcareous ring. Although not formally tested with a phylogenetic framework, apodids have apparently lost their dermal ossicles multiple times. If these reversions hold true, Gymnopipina gen. nov. represents the fourth independent loss of dermal ossicles in the class Holothuroidea. An identification key to the Brazilian apodid species is also provided.

Abstract Rhabdias stomatica sp. nov. from the lungs of Duttaphrynus stomaticus (Lutken, 1864) from Dehradun, Uttarakhand, India is described and illustrated. Rhabdias stomatica sp. nov. is the 16th species described from the Oriental biogeographical region and the 8th species from India. The new species is differentiated from the closely related Oriental species in having 4 weakly developed lips, a trapezoidal shaped buccal cavity, different position of nerve ring and in the esophagus/body length ratio. In addition, to the new species found in the lungs, mature specimens of Aplectana macintoshii (Stewart, 1914) Travassos, 1931 and larvae representing two unidentified species of nematode were found in the large intestine of the D. stomaticus.

AbstractA new species and genus of nematodes (Ungellidae, Drilonematoidea) parasitic in the coelomic cavity of Notiodrilus bovei deposited in the collection of the Museum für Naturkunde in Berlin, is described and illustrated. Malvinia crassa gen. n., sp. n. is characterised by its short, bloated, curved body tapering to both ends, paired, superficially attached cephalic hooks, short infundibular stoma, a pharynx comprising a pre-corpal bulb-like swelling, procorpus, isthmus and basal bulb, nerve ring encircling isthmus, excretory pore located posterior to the nerve ring, weakly cuticularised excretory duct, vulva, slightly post-median, short precloacal process in males, large grain-like spermatids, sperm in spermatheca ball-shaped, ca 20 μm diam., composed of smaller particles resembling spermatids; symmetrically placed, large, fimbriate caudal organs lacking a cavity, and absence of amphids, cephalic and male cloacal sensilla and post-uterine sac. Malvinia gen. n. is differentiated from all genera of the Ungellinae on the basis of its small size, vesiculate vs vermiform body shape, very long reflexed portion of testis and highly modified sperm. From the closest species of the genus Ungella, the new species differs by the presence vs absence of a stoma and pre-corpal swelling of the pharynx, structure of fimbriate caudal organs, larger spermatids in male and sperm in female spermatheca, and absence of lateral differentiation of the cuticle. A key to the genera of Ungellinae is proposed.
