The Andean cloud forests of western Colombia and Ecuador are home to several endemic mammals; members of the Oryzomyini, the largest Sigmodontinae tribe, are extensively represented in the region. However, our knowledge about this diversity is still incomplete, as evidenced by several new taxa that have been described in recent years. Extensive field work in two protected areas enclosing remnants of Chocó montane forest recovered a high diversity of small mammals. Among them, a medium-sized oryzomyine is here described as a new genus having at least three new species, two of them are named and diagnosed. Although externally similar to members of the genera Nephelomys and Tanyuromys, the new genus has a unique molar pattern within the tribe, being characterized by a noticeable degree of hypsodonty, simplification, lamination, and third molar compression. A phylogeny based on a combination of molecular markers, including nuclear and mitochondrial genes, and morphological data recovered the new genus as sister to Mindomys, and sequentially to Nephelomys. The new genus seems to be another example of a sigmodontine rodent unique to the Chocó biogeographic region. Its type species inhabits cloud forest between 1,600 and 2,300 m in northernmost Ecuador (Carchi Province); a second species is restricted to lower montane forest, 1,200 m, in northern Ecuador (Imbabura Province); a third putative species, here highlighted exclusively by molecular evidence from one immature specimen, is recorded in the montane forest of Reserva Otonga, northern Ecuador (Cotopaxi Province). Finally, the new genus is also recorded in southernmost Colombia (Nariño Department), probably represented there also by a new species. These species are spatially separated by deep river canyons through Andean forests, resulting in marked environmental discontinuities. Unfortunately, Colombian and Ecuadorian Pacific cloud forests are under rapid anthropic transformation. Although the populations of the type species are moderately abundant and occur in protected areas, the other two persist in threatened forest fragments.

The genus Concavetettix Deng, gen. nov. (type species: Concavetettix yunnanensis Deng, sp. nov.) is described from Daweishan, Pingbian County, Yunnan Province, China. The genus Macromotettix Günther, 1939 is reviewed. Three new species of the genus, M. microptera Deng, sp. nov., M. zhengi Deng, sp. nov. and M. brachyptera Deng, sp. nov. are described with detailed illustrations of external morphology. One new name is proposed: Macromotettix napoensis Deng, nom. nov.. Additionally, an updated key to species of the genus Macromotettix is given.

Studies on the Agalliini leafhoppers collected from the Terrestrial Arthropods of Madagascar inventory project of the Cal-ifornia Academy of Sciences, resulted in the discovery of one new genus Agallidwipa gen. nov. (type-species: A. biramosa sp. nov.) with three new species, A. biramosa sp. nov., A. bispinosa sp. nov. and A. webbi sp. nov. and three new species of the genus Igerna Kirkaldy, I. delta sp. nov., I. flavocosta sp. nov. and I. malagasica sp. nov. Two new combinations proposed are Agallidwipa pauliana (Evans) comb. nov. (from genus Agalliana Oman) and Igerna neosa (Webb) comb. nov. (from genus Stonasla White), a species previously recorded from Aldabra Islands. A previous record of Igerna bi-maculicollis (Stål) from Madagascar is shown most likely to be a case of misidentification. All the taxa are described and illustrated. Keys to species of Agalliini from Madagascar are included along with notes on the distinction between Agal-liana and Agallidwipa.

AbstractAngilovelia n.gen. is described with Velia y-alba Paiva, 1918, from Burma as type-species and only included species. It has stridulatory devices similar to those found in species of the Neotropical genus Stridulivelia Hungerford. Three new species of Angilia Stål subgenus Adriennella Poisson are described, A. orientalis n.sp. (Thailand, Hong Kong), A. bispinosa n.sp. (Thailand), and A. trispinosa n.sp. (Malayan Peninsula?). The Palaearctic genus Velia Latreille reaches the border zone between this region and the Oriental region. V. (Plesiovelia) affinis Kolenati ssp. marussii Tamanini, described from Hindukush (Afghanistan, Pakistan), is here recorded from Kashmir (India) and the first species of the genus is described from China, V. (Haldwania) sinensis n.sp. A key is given to the genera and subgenera of Veliinae of the world.

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.

AbstractThe Oriental genus Baptista Distant is redescribed and compared with other genera of Old World Microveliinae. The type-species, B. gesiroi Distant, hitherto only known from the type specimens (from Burma), is redescribed and recorded from Thailand. Three new speeies are described: B. femoralis sp. n. (Thailand, West Malaysia), B. digitata sp. n. (Thailand), and B. angulata sp. n. (southern India). These species all live in very cryptic and secluded habitats, like wet litter, small watery holes in rocks, or small cavities under turf along streams. The males of the new species exhibit a remarkable polymorphism in the structure of fore Iegs and pregenital abdomen. A closely related genus, Lathriovelia gen. n., is described with two species, L. capitata sp. n. and L. collaris sp. n., both from West Malaysia. This genus has a head structure which is quite unique within the subfamily.

The genus Amberana Distant is revised. Three new species, A. attei Soulier-Perkins sp. n., A. ouvrardi Soulier-Perkinssp. n. and A. pascali Soulier-Perkins sp. n. are described. Lectotypes are designated for A. dimidiata (Signoret, 1960), A.fissurata Jacobi, 1917, A. noualhieri (Lallemand, 1920), A. sexguttata (Melichar, 1915) and A. uncinata Jacobi, 1917. Am-berana tripunctata var. completa Lallemand, 1949 and A. tripunctata Lallemand, 1920 are synonymised with A. bergevini(Lallemand, 1920). A new genus, Bourgoinrana Soulier-Perkins gen. n., is erected for B. perinetana (Synave, 1957),comb. n. (type species), B. rubescens (Synave, 1957), comb. n. and B. sandrangatensis (Synave, 1957), comb. n. Keysto species of Amberana and Bourgoinrana Soulier-Perkins gen. n. are provided. Drawings of the male genitalia for all species with exception of A. lemuria (Distant, 1908) are included.

AbstractAll Oriental and Australasian/Oceanic species of Pegadomyia are re-examined. A detailed study of the generic characters shows that Pegadomyia actually contains two easily diagnosed genera: Pegadomyia Kertész, 1916 and Pseudopegadomyia gen. n. Pegadomyia now includes the type species P. pruinosa Kertész, 1916 (occurring in Malaysia, Taiwan and Thailand) and three new species: P. ceylonica sp.n. (from Sri Lanka), P. nana sp.n. (from Laos) and P. nasuta sp.n. (from Malaysia). Pseudopegadomyia contains Ps. jamesi sp.n. (based on a type series from the Philippines) and two species originally belonging to Pegadomyia: Ps. glabra (Bezzi, 1928), comb.n. (Fiji Is.) and Ps. nuda (James, 1948), comb.n. (Australasian Region and Philippine Is.). Figures of the diagnostic characters of all treated species are included. Identification keys and a map showing the distribution of all species of both genera are presented.

The choniostomatids parasitic on Crustacea have been exhaustively studied by Hansen. To the six genera and forty-three species he had described in 1897, he added a new genus and three more species in 1904, and seven more species in 1923. Scott (1904, 1905, 1907) described seven more species, Fraenkel (1915) three new species, Monod (1930) one, and Blake (1929) two. In 1929, however, Connolly described a new genus Choniosphaera and its type species C. cancrorum, from parasites found on American crabs Cancer amoenas, C. irroratus and C. borealis. In the present paper a new species Choniosphaera indica, parasitic on the edible crab Neptunus sanguinolentus of Madras, is described.
