Abstract Two new species of diplogastrid nematodes from India are described and illustrated. Diplogasteroides uriceus sp. n. has a medium-sized body, monoprodelphic reproductive system lacking a post-uterine sac, anteriorly directed muscular vagina and vulva located far posterior; long, slender, arcuate spicules; gubernaculum with proximal thread-like flexible part and nine pairs of genital papillae of which four pairs are precloacal and five pairs postcloacal. The new species resembles D. crassus but can be most easily differentiated by the structure of the cheilorhabdions, shape and structure of the gubernaculum, arrangement of the genital papillae and the complete absence of a bursa. The new species also resembles D. proprius but can be differentiated by stoma structure, more anteriorly located vulva, longer spicules, gubernaculum shape and tail form. Rhabditidoides papillatus sp. n. is characterised by the presence of three pairs of post-deirids in the lateral fields, posteriorly curved tubular stoma, amphidelphic female reproductive system, strongly developed, arcuate spicules with bilobed capitulum and a slender gubernaculum provided with a sleeve distally and anteriorly directed bifid ends proximally. It can be distinguished from R. stigmatus by the structure of the spicule head, gubernaculum shape and arrangement of the genital papillae; from R. mastigurus by spicule structure and the gubernaculum shape; and from R. quercophilus by a more slender female body, stoma structure, absence of a male bursa, spicule form and arrangement of the genital papillae.

The Stenothemus harmandi species-group has 10 species at present. They are S. harmandi (Bourgeois, 1902) (located in N. India, Nepal); S. holosericus Švihla, 2005, S. orbiculatus Švihla, 2005 and S. subnitidus Švihla, 2005 (N. India); S. distortirudis Y. Yang & X. Yang, 2014, S. laticollis Y. Yang & X. Yang, 2014, S. parallelus Y. Yang & X. Yang, 2014 and S. septimus Y. Yang & X. Yang, 2014 (China: Xizang); S. fugongensis Y. Yang & X. Yang, 2014 (China: Yunnan) and S. leishanensis Y. Yang & X. Yang, 2014 (China: Guizhou). In the present study, two previously-known species are classified into this species-group, S. dentatus Wittmer, 1974 and S. alexandrae Švihla, 2004, of which the latter as a subspecies of the former is upgraded to the specific level and another two new species are discovered and described. Two new species of the Stenothemus harmandi species-group are described, S. acuticollis sp. n. (China: Yunnan) and S. nigricolor sp. n. (China: Xizang), which are illustrated with habitus photos and aedeagi of males, abdominal sternites VIII and internal genitalia of females. S. alexandrae Švihla, 2004 stat. n. is upgraded from a subspecies of S. dentatus Wittmer, 1974 and the two species are classified into this species-group. Characters of the female reproductive system are described for the first time for the following species: S. distortirudis Y. Yang & X. Yang, 2014; S. laticollis Y. Yang & X. Yang, 2014; S. leishanensis Y. Yang & X. Yang, 2014; S. orbiculatus Švihla, 2005; S. septimus Y. Yang & X. Yang, 2014 and S. subnitidus Švihla, 2005. Meanwhile, some additional distribution information is added for previously-described species. A key for the identification of all species is updated.

AbstractThree known and two new species of Aphanolaimus are described, viz. A. louisae, A. seshadrii, A. brasiliensis, A. aberrans sp. n. and A. vietnamicus sp. n. New data on the morphology and distribution of A. louisae, A. seshadrii and A. brasiliensis are given. The male of A. brasiliensis is described for the first time: it is characterised by the presence of one pair of neck setae, four tubular supplements, two precloacal and six caudal setae, 13-18 μm long spicules with oval manubrium and gradually narrowing shaft, platelike gubernaculum. Aphanolaimus aberrans sp. n. is characterised by a 495-681 μm long body, longitudinally striated cuticle, presence of 24-34 lateral epidermal glands, weakly sclerotised stoma, amphid with central elevation, lateral field starting on the third to seventh annule, oval ventral gland cell; female reproductive system with developed spermathecae, straight vagina without sclerotisations; male with one pair of neck setae, with two or three small tubular supplements and three or four caudal setae, 13-18 μm long spicules with oval manubrium and gradually narrowing shaft, plate-like gubernaculum. Aphanolaimus vietnamicus sp. n. is characterised by a 544-569 μm long body, longitudinally striated cuticle, presence of 19 lateral epidermal glands, weakly sclerotised stoma, amphid with central elevation, lateral field starting on 14th-18th annule, oval ventral gland cell; female reproductive system with developed spermathecae, straight vagina without sclerotisations; male with one pair of neck setae, with two tubular supplements and four caudal setae, 12 μm long spicules with oval manubrium and gradually narrowing shaft.

A new species of mouthless nematode Parastomonema papillosum sp. nov. was described based on specimens collected in muddy sediments of a mangrove forest in Samut Songkhram, Thailand. Parastomonema papillosum sp. nov. is the second species of the genus and differs from the type species P. fijiense Kito, 1989 in having short body length (1.5–3.0 mm), short cephalic setae (1.5–2.6 µm), and a weakly cuticularized gubernacular apophysis in the male. Astomonematinae subfam. nov. was erected for the two mouthless genera Astomonema and Parastomonema in the Siphonolaimidae based on the diagnostic feature of a degenerate alimentary canal and female reproductive system with paired ovaries.

AbstractTwo new nematode species of the genus Mesacanthion, M. obscurum sp. n. and M. propinquum sp. n., both isolated from sediment in the Mediterranean Sea off the coast of Israel, are described and illustrated. Mesacanthion obscurum sp. n. is similar to M. diplechma and M. southerni, but differs from the first species by having a narrower labial region, shorter outer labial setae, shorter right spiculum, and shorter distance from supplement to cloacal aperture; and from the second species by a shorter female body, shorter outer labial setae, shorter distance from supplement to cloacal aperture, and the presence of a ventral protuberance on the male tail. Mesacanthion propinquum sp. n. resembles M. southerni and M. obscurum sp. n., but differs from the first species by having a shorter female body, less slender tail, narrower labial region, shorter outer labial setae, shorter distance from supplement to cloacal aperture, and absence of transverse striations on the right spicule; and from M. obscurum sp. n. by the shorter outer labial setae (10-15 vs 37-44 μm), shorter distance from supplement to cloacal aperture (28-31 vs 36-59 μm) and absence of transverse striations on the surface of the right spicule. A key is provided for those Mesacanthion species possessing anisomorphic and anisometric spicules.

The new species is characterised by a female body length of 630-946 μm, lateral field with four lines, a short 12.6-13.9 μm long stylet with small basal swellings, excretory pore located posterior to nerve ring, outstretched reproductive system with amoeboid sperm inside the spermatheca, a well-developed vulval flap, tail conical and straight with a 1.9-4.8 μm long mucron at the tip, and lacking males in both the wild type and fungal-cultured populations. In a concatenated tree, reconstructed on the basis of the partial 18S, full length ITS and partial 28S rDNA D2-D3 sequences, the new species occupied a basal placement to the clade of xylophilus-group and africanus-group species.

Paraphanolaimus paraguayensis sp. n. is characterised by 0.84-0.94 mm long body, presence of 37-44 lateral epidermal glands, strongly sclerotised and broad cylindrical stoma, swollen tail tip; female reproductive system with developed spermathecae, straight vagina; male without neck setae, 16-19 tubular supplements, two precloacal and nine to ten caudal setae, spicules 32-33 μm long, arcuate, with oval manubrium and fusiform shaft, platelike gubernaculum. Paraphanolaimus indicus and P.micoletzkyi are considered as species inquirendae. An emended diagnosis and a revised classification of Paraphanolaimus are proposed and a key to the species of the genus is provided. Aphanonchus bayensis (Keppner, 1988) comb. n. is proposed for Paraphanolaimus bayensis Keppner, 1988.
