Triteleia Kieffer is a little known scelionid genus. Two species, viz., flagellata Abhilash and Rajmohana sp. nov. and T. robusta Abhilash and Rajmohana sp. nov. are described as new to science. Further T. bengalensis (Saraswat), the only species known under Triteleia in India, is redescribed and a dichotomous key to the three Indian species of Triteleia is provided.

Two New Species

Unclear boundaries between species hinder identification in the field and in herbaria, especially in species groups that can only be distinguished on the basis of subtle morphological and ecological features. One such taxon is Ficinia indica, widespread in the Greater Cape Floristic Region, growing on deep sandy soils between sea level and 1000 m elevation. Within its range, several phylogenetically related and morphologically similar species co-occur or occupy distinct habitats. Studies in herbaria show species in the Ficinia indica complex to be largely misidentified based on the use of qualitative information. Here, we investigate whether the six taxa recognized, based on one or a few characters, are supported as distinct species based on multivariate analysis of macro-morphological data. Two of the taxa were mostly separated whereas the other four taxa overlapped in multivariate space, but all the taxa could be distinguished using a single or a combination of morphological and ecological characters. We uphold the four previously recognized taxa (Ficinia argyropus, F. elatior, F. indica, F. laevis) as species, describe two new species (F. arnoldii and F. montana), and provide a dichotomous key for their identification.

Genus Two

Okubasca Dworakowska, 1982, formerly treated as a subgenus of Empoasca Walsh, 1862, is elevated to status as a separate genus. Two new species of Okubasca from China are described and illustrated: Okubasca convoluta Yu & Yang sp. nov.; Okubasca paracalvata Yu & Yang sp. nov. Okubasca convoluta is similar to O. okubella in having the aedeagal shaft about as long as the preatrium but differs in having the aedeagus of uniform thickness in lateral view, the anal tube process straight and the face mostly black. Okubasca paracalvata resembles Okubasca calvata in aedeagal shape, but differs in having a lamellar swelling and a small tooth on the dorsal side of the aedeagus, and the vertex anterior margin rounded.

The genus Cephaloscyllium Gill 1862 (Chondrichthyes, Carcharhiniformes, Scyliorhinidae) until recently had only two species recognized, C. isabellum [= C. umbratile (Jordan & Fowler 1903)] and C. fasciatum Chan 1966, from the western North Pacific (WNP), with one dubious species, C. formosanum, having been described by Teng in 1962. Recently, three additional species were described, C. circulopullum Yano et al. 2005, C. sarawakensis Yano et al. 2005, and C. parvum Inoue & Nakaya 2006 from this region. Here we present a revision of this genus for the WNP, including redescriptions of C. fasciatum and C. umbratile based on the holotypes, a re-examination of the recently described species, and descriptions of two new species from Taiwan. Cephaloscyllium umbratile can be distinguished from its congeners based on maximum size, length of first dorsal-fin base, anal–caudal space, and dorsal–caudal space. We conclude, based on a comparison of C. parvum and C. sarawakensis, that the former is a junior synonym of the latter species. The two new Taiwanese species can be separated from other WNP species by color pattern, shape of the anterior nasal flap, anal and dorsal-fin size, internarial width, and mouth size. Finally, we present a revised dichotomous key to the WNP Cephaloscyllium recognizing six contemporary taxa: C. circulopullum, C. fasciatum, C. sarawakensis, C. umbratile, C. pardelotum sp. nov. and C. maculatum sp. nov.

Unknown Male

The genus Ajothrips was erected for two new species from India (Bhatti 1967), although subsequently a third Indian species was added (Bhatti 1997). All three species have remained known only from females, although Mound (2009) recorded the presence of sternal pore plates in unspecified males of this genus. The purpose of this note is to record the type species, A. karma, from China, and to describe the unknown male. The systematic position of the genus has a confusing history. Considered by Bhatti (1967) as related to Scirtothrips, it was subsequently excluded from the Scirtothrips genus-group (Masumoto & Okajima 2007). However, more recent studies (Ng & Mound 2015; Lima & Mound 2016) have retained the systematic relationship proposed by Bhatti.

Emended Diagnosis

Two new species of free-living nematodes discovered from the sediments in the East China Sea are described: Linhystera breviapophysis sp. nov. and L. longiapophysis sp. nov. Both species possess a dorso-caudally directed gubernacular apophysis, which makes them distinctly different from the two already known species of Linhystera. Linhystera breviapophysis is characterized by a gubernacular apophysis about 3.3 μm long, the presence of a crown of cervical setae and a filiform tail. Linhystera longiapophysis is characterized by a prominent gubernacular apophysis about 10 μm long, sparse cervical setae and a long filiform tail. An emended diagnosis of Linhystera and a pictorial dichotomous key to the species are given.

This contribution aims to revise the taxonomy of the genus Heptodonta Hope, 1838, and provides a dichotomous key to the 15 species of this genus. Each species is described in detail with colour photographs of habitus and diagnostic characters. Information on distribution and biology of each species is provided. Heptodonta abasileia sp. nov., H. halensis sp. nov., H. horii sp. nov., H. schuelei sp. nov., H. tempesta sp. nov. and H. wiesneri sp. nov. are described. Heptodonta nigrosericea (W. Horn, 1930), stat. nov. is raised to species rank. Heptodonta ferrarii Gestro, 1893, syn. nov. and H. ferrarii shooki Wiesner, 1986, syn. nov. are placed into synonymy under H. pulchella (Hope, 1831). Heptodonta lumawigi Wiesner, 1980, syn. nov. is placed into synonymy under H. nigrosericea stat. nov. Females of H. vermifera W. Horn, 1908, and males of H. mindoroensis Cassola, 2000, are described for the first time. Lectotypes are designated for H. analis (Fabricius, 1801), H. arrowi W. Horn, 1900, H. ferrarii Gestro, 1893, H. hopei Parry, 1844, H. melanopyga (Schaum, 1862), H. nigrosericea (W. Horn, 1930), H. posticalis (White, 1844), H. pulchella (Hope, 1831), H. thongdii Fleutiaux, 1919, H. variipes (Chaudoir, 1850), H. vermifera W. Horn, 1908, and H. yunnana (Fairmaire, 1887). Holotype is designated by monotypy for H. eugenia Chaudoir, 1865. Regionally restricted records of two new species from the Philippine island Negros and one new species from the northeast Indian Garo Hills highlight the high conservation value of these rather small-scale regions.
