Gemmellaroia is a conical Permian brachiopod that traditionally has been assigned to the superfamily Richthofeniacea [sic] on the basis of its conical shape and a myocoelidium in the ventral valve. It has been considered unique among brachiopods in opening the shell by having the dorsal valve move straight up, rather than rotating around a hinge axis. Evidence is adduced to warrant transfer of the genus and its cohorts to the superfamily Derbyoidea (totally unrelated to the richthofenioids) and to demonstrate that it was capable of opening in the normal manner, rotating the dorsal valve about a hinge axis. Members of the family include Gemmellaroia (Cossmann, 1898), Loczyella Frech, 1901, Tectaria (Likharev, 1928), and Cyndalia (new genus with type species C. rudistiformis new species).

A new genus, Platnickgen. n., with three new species, P. shablyaisp. n. (♂, type species), P. astanasp. n. (♀) and P. sangloksp. n. (♀), are described from Tajikistan. The male of the type species has a unique pair of longitudinal ventral postgastral scuta. Females have such scuta also, but they are much shorter. The new genus is placed in Liocranidae Simon, 1897. A discussion on the subfamilies of Liocranidae and comments on the family-group names are provided.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.

A new genus of odiniids (Odiniidae: Traginopinae) is described from Brazil, Pauximyia gen. nov., with two species, P. oliveirai sp. nov. (type species) and P. vidali sp. nov. A modified key to the Neotropical genera of the family and for the two Pauximyia gen. nov. species is provided.

A new candonid genus,Schornikovdonagen. nov., with its type speciesSchornikovdona bellensissp. nov., is described from rheocrene springs of Bell County, Texas. It is designated to the tribe Candonini due to the smooth carapace surface, normal pore openings with sensory seta, the presence of a 5-segmented first antenna, two long sexual bristles on the second antenna in males, the narrowly fused terminal segment of the Md palp, a long penultimate segment of the Mxl palp, two long and one short setae on the terminal segment of T3, the absence of an “e” seta on T3, the presence of a posterior seta on the uropod, the presence of 5 + 2 rows of spines on Zenker’s organ, and other characteristics found in the tribe. The main diagnostic characteristics separating the new genus from the other genera in the tribe are the shape of the carapace, the reduced numbers of segments in the first antenna, reduction or absence of exopodial setae in the second antenna, asymmetrical clasping organs, the uropod with one rod-shaped claw, the different shape of the hemipenis, and differences in parts of the chaetotaxy. Based on these differences, we proposeSchornikovdonagen. nov. as a new genus, with the new speciesS. bellensissp. nov., in the subfamily Candoninae in the family Candonidae.

Three new Oriental Issidae genera and two new species identified by a previous molecular phylogeny analysis are described. Two new genera belong to the tribe Kodaianellini: Kodaianellissus gen. nov., type species: K. intorqueus sp. nov. from China and Tetricissus gen. nov., type species: T. philo (Fennah, 1978) from Vietnam. Another new genus representing Sarimini: Longieusarima gen. nov., type species: L. lunulia sp. nov. is described from China.

Species previously attributed to Necrotauliidae are revised from the Late Triassic and Early Jurassic of England based on examination of type specimens and non-type material. The necrotauliids have been considered as a basal family of caddisflies (Trichoptera) or as a paraphyletic assemblage of stem-amphiesmenopterans. Herein a new genus, Austaulius, is erected which includes all Lilstock Formation∖Lower Lias material from England; the previously described species are synonymized with A. furcatus and a new species, A. haustrum, is described from the Dorset Coast, the holotype of which preserves synapomorphic traits of the Trichoptera not previously described suggesting that the family is trichopteran. The type genus remains Necrotaulius and type species N. parvulus (Geinitz, 1884) from the type locality of Dobbertin, Germany. One species of Necrotaulius is represented in the UK, N. parvulus, which is found in the Upper Lias.

In the fourth part of the revision on the Asian Metarbelidae we describe the new genus Tagoria Yakovlev & Zolotuhin, gen. nov. (type species, by original designation: Arbela watsoni Hampson, 1900). The male and female of Tagoria watsoni (Hampson, 1900) comb. nov. are redescribed, the new species Tagoria dierli Yakovlev & Zolotuhin, sp. nov. (type locality: Nepal, Rapti Tal, Monahari Khola, Belwa) is described.

The genus Ukamenia Oku (1981) was proposed with Simaethis sapporensis Matsumura (1931) from Japan as its type species, which had been originally described in the family Choreutidae. Oku (1981) based the new genus on characters of S. sapporensis that were typical of Tortricidae rather than Choreutidae, notably the naked haustellum (scaled in Choreutidae), among many other characters differing between the two families, such as wing venation, head morphology, and genital form. Oku (1981) assigned his new genus to the tribe Olethreu­tini, but mentioned that it resembled the genus Gatesclarkeana Diakonoff, 1966. In her extensive study of Australian Olethreutinae, Horak (2006) briefly noted Ukamenia as being referable to Gateclark­eanini.

A new genus of mylagaluid rodent from the Miocene of the Great Basin, Hesperogaulus, is described, and to it two new species, H. gazini and H. wilsoni (type species) are referred. This genus differs from all other genera of later Tertiary mylagaulines in having: large bosses of rugose bone on the anterior end of the nasal bones; lower slope of the occipital bone; and unique separation of the anterior branches of the forked parafossette on the upper premolar.Hepserogaulus n. gen. represents a distinct lineage of mylagaulids that has been separate from other members of the family since the early Barstovian. This genus is geographically limited to the Great Basin. Other later Tertiary genera of mylagaulids show geographic limitations to other parts of the continent as well.

Bicaubittacus gen. nov., the second genus of the family Bittacidae from the Oriental Region, is erected with Bittacus appendiculatus Esben-Petersen, 1927 as its type species. A key to the 17 extant genera of Bittacidae is compiled to include the new genus. Two new species, Bicaubittacus yangi sp. nov. and Bi. mengyangicus sp. nov. are described and illustrated from China. Three new combinations, Bicaubittacus appendiculatus (Esben-Petersen, 1927) and Bi. longiprocessus (Huang & Hua, 2005) from China, and Bi. burmanus (Tjeder, 1974) from Myanmar (formerly Burma), are transferred from the genus Bittacus Latreille. A key to the five species of Bicaubittacus is provided. The validity of Neobittacus and Thyridates is briefly discussed
