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.

Based on nymphs collected in Espírito Santo and Amazonas, Southeastern and Northern Brazil, two new species of the genus Rivudiva Lugo-Ortiz & McCafferty, 1998 (Ephemeroptera: Baetidae) are described. Rivudiva inma sp. nov. shares several characteristics with R. minantenna Lugo-Ortiz & McCafferty, 1998, but can be distinguished by details of leg setation, such as length and shape of robust setae and presence of setae on trochanter. Rivudiva oonirikoperi sp. nov. is more similar to R. trichobasis Lugo-Ortiz & McCafferty, 1998, but can be separated by the absence of setae on scape and pedicel, shape of distal margin of labrum, and length of maxillary palp. New diagnoses and illustrations are provided for R. minantenna and R. trichobasis, as well as a key to the known nymphs of Rivudiva species.

Two new species of Diplura C. L. Koch 1850 are described from Brazil: Dipluramapinguari sp. n., from the state of Rondônia in southeastern Amazonia, northern Brazil, and Diplurarodrigoi sp. n., known from southeastern and central west regions of Brazil. Diplurarodrigoi sp. n. is morphologically similar to D.lineata (Lucas, 1857), D.sanguinea (F. O. Pickard-Cambridge, 1896), and D.mapinguari sp. n. Comments on diagnostic characters of Diplura are included. The synonymy of D.maculata (Mello-Leitão, 1927) with D.catharinensis (Mello-Leitão, 1923) is corroborated. A classification of color pattern of the dorsum of the abdomen is given.

Middle Pair

Isosoma Allynii, n. s.Female.—Average length .10 of an inch. Color of body and antennæ uniform black, the first with a slight greenish lustre. Head about .025 of an inch wide, about two thirds as long; the antennæ a little enlarged at the ends, hairy, microscopic hairs moderately scattered over the head and thorax. Thorax, as well as head, punctured; wings hyaline, dotted over with microscopic hairs, the thorax in its widest part about the width of the head. Abdomen gradually tapering from near the base, the ovipositor slightly exserted. The color of the legs vary slightly; in five specimens the anterior and posterior legs have the femurs fuscous except at the ends; the tibiæ with basal half fuscous, the rest yellow; the terminal joint of tarsi fuscous, the rest yellow; the middle pair of legs are yellow throughout except the terminal tarsi. Two specimens have all the femurs fuscous, yellow at the ends. One specimen has all the femurs pale red, and the tibiæ fuscous, but this is probably a change from yellow by the poison bottle used in killing. One is marked like the first five, with the yellow replaced by pale red; another is like the first five, except that the middle tibiæ are a little clouded at base.

Two New Species

The genus Thyridosmylus Krüger (Neuroptera: Osmylidae) belongs to the subfamily Spilosmylinae based on the type species Osmylus langii Mclachlan 1870 (Krüger 1913). The genus has 19 species mainly distributed in Asia, especially in China where there are 14 species: Thyridosmylus polyacanthus sp. nov., Thyridosmylus trimaculatus sp. nov., Thyridosmylus minoroides Yang, 1987, Thyridosmylus laetus Yang, 1988, Thyridosmylus pulchrus Yang, 1988, Thyridosmylus medoganus Yang, 1988, Thyridosmylus similaminor Yang, 1992, Thyridosmylus trifasciatus Yang, 1993, Thyridosmylus triypsiloneurus Yang, 1995, Thyridosmylus maolanus Yang, 1993, Thyridosmylus qianus Yang, 1993, Thyridosmylus fuscus Yang, 1999, Thyridosmylus vulgatus Yang, 1999 and Thyridomsylus pallidius Yang, 2002. Three species are described from India (Thyridosmylus langii (McLachlan 1870), Thyridosmylus perspicillaris (Gerstaecker, 1885), Thyridosmylus pustulatus Kimmis 1942) while another two species are known from Madagascar (Thyridosmylus marmoratus Fraser, 1955 and Thyridosmylus punctulatus (Navás, 1933)). Gerstaecker (1885) described one subspecies Thyridosmylus perspicillaris perspicillaris Gerstaecker and Kimmins (1942) erected three additional subspecies, Thyridosmylus langii angustus Kimmins, 1942, Thyridosmylus perspicillaris fenestratus Kimmins, 1942, Thyridosmylus perspicillaris minor Kimmins, 1942. However due to rampant variation in colouration and venation, the valid status of these subspecies is doubted and they are provisionally treated as synonyms herein. Thyridosmylus is characterised by fuscous and maculate forewings and largely hyaline hind wings, moderately sized and usually ochreous body, costal cross-veins simple and radial field with numerous cross veins (not including gradates). In the male genitalia, the anal plate generally elevates into a fingerlike process on the dorsal margin, and parameres are commonly arcuate in lateral view. Female genitalia usually have a broad anal plate, while the gonapophysis lateralis is finger-like or coniform in lateral view. In this paper, two new species are described from China. Terminology follows Tjeder (1957) and New (1986). All the type specimens are deposited in the Entomological Museum of China Agricultural University (CAU), Beijing.

Of the 69 Neotropical species of Stylogaster, only one record was previously known from Northeastern Brazil (from Bahia state in 1985—S. brasilia Camras & Parrillo). Several specimens from this region housed at the MNRJ collection were studied, mostly from Bahia, Ceará and Pernambuco states. Two new records were obtained: S. macrura Lopes, 1938, previously known from São Paulo state (Southeastern Brazil), and S. souzai Monteiro, 1960, from Amapá and Pará (Northern Brazil). Descriptions of two new species, S. hugoi sp. nov. and  S. planitarsis sp. nov. are presented, as well as that of the previously unknown female of S. souzai. Illustrations and geographic distribution of the species are also provided.

Two new species of Hemiosus (Coleoptera: Hydrophilidae) from the central cordillera of the Colombian Andes are described. Hemiosus molanoi González-Rodríguez & García-Hernández sp. nov. and H. quindiensis González-Rodríguez & Clarkson sp. nov. are described based in 56 adult specimens collected in river-associated sandy puddles (26 specimens of H. molanoi sp. nov.) and temporary puddles near crops (26 specimens of H. quindiensis sp. nov.). Both species are identified mainly by characteristics of the aedeagus: Hemiosus molanoi sp. nov. has subtriangular parameres, median lobe shorter than parameres and longer than appendices which are acuminate and phallobase shorter than parameres, strongly asymmetrical in basal two-fifths; H. quindiensis sp. nov. has parameres gradually tapering towards rounded apices, median lobe shorter than parameres and longer than appendices which are acuminate and phallobase shorter than parameres, strongly asymmetrical in basal half. Dorsal coloration pattern, overall shape of the meso- and metaventral process and abdominal ventrites are also informative to distinguish the new species from remaining described Hemiosus. Diagnoses, illustrations and habitat characteristics are provided.

Two New Species

Two new species of the genus Pristaulacus, P. ohishii sp. nov. and P. uenoi sp. nov. are described from Japan. The former species belongs to the comptipennis species group in having the strongly concaved occipital margin, and is peculiar in the species group in having the combination of the interrupted occipital carina and a broadly rounded and shallow occipital medial groove. The latter species resembles P. ryukyuensis in having the occipital carina not interrupted, the anterior margin of mesoscutum in lateral view acute and veins M+Cu, r-m and Cu of hind wing not pigmented, but they can be easily distinguished by the coloration of mesosoma and the dark spots of fore wing.
