Dorsal habitus, head, pronotum, elytra and male genitalia of all species are figured and a distribution map is included. Incadorcus cuzcoensis Arnaud, Noguchi & Bomans is elevated to species status and Incadorcus kirchneri Schenk is synonymized with Incadorcus michellae Arnaud & Bomans. The species Metadorcus rufolineatus Nagel and Aegognathus nigrosuturalis Weinreich are transferred to the genus Onorelucanus.

查看更多>>摘要：Augochlora is a genus of mainly tropical bees, with few representatives in both North and South American temperate areas. In this contribution we present a taxonomic review of the species with southernmost distribution. Only five species occur in central Argentina and Uruguay, between 30° and 40° south latitude: A. iphigenia Holmberg, A. amphitrite (Schrottky), A. nausicaa (Schrottky), A. phoemonoe (Schrottky) and A. daphnis Smith. The first four species are common elements in the bee assemblages of the area. The fifth species, from Montevideo, Uruguay, is known from the type specimen only. Re-descriptions of all species, as well as illustrations, distributional data, and taxonomic keys are presented. A lectotype is designated fox Augochlora iphigenia Holmberg, 1886. Oxystoglossa semiramis Schrottky, 1911, and Halictus brochidens Vachal, 1911, are new synonyms of A. iphigenia Holmberg. Odontochlora thebe Schrottky, 1909, is a new synonym of Odontochlora amphitrite Schrottky, 1909.
查看更多>>摘要：A new species of Asthenopus, A. crenulatus sp. nov. is described from adults of both sexes from Brazil and Colombia. The new species is diagnosed by: male foreleg length 0.7-0.9 times the length of fore wing, marginal intercalary veins on the entire margin of fore and hind wings generally shorter than distance between longitudinal veins, forceps and penes long and slender, penes with many subapical spines. This new species is closely related with A. picteti (Hubbard). A key to the male adults of Asthenopus is included.

Corypho-rus aquilus (Coryphoridae), Amanahyphes saguassu and Tricorythopsis yucupe (Leptohyphidae) are newly recorded for Venezuela, the adults ofthe last species are described for the first time. Macunahyphes pemonensis sp. nov. and Macuna-hyphes incognitus sp. nov. (Leptohyphidae) are described from adults from Venezuela and Brazil, respectively. Both new species of Macunahyphes are very nearlyrelated, and are characterized among other features, by the absence of forceps, and the great development of large paired projections on the styliger plate. Caenis teipunensis sp. nov. (Caenidae) is also described from adults, its diagnostic charactersinclude: forceps apically sharp and sclerotized, and very large apophyses of the styliger sclerite. We give fiew locality records for Tricorythopsis volsellus, previously known from other localities in Venezuela.
查看更多>>摘要：Aleuropleurocelus hyptisemoryi Gill sp.n. (Hemiptera: Aleyrodidae) and its parasitoid, Encarsia heratyi Polaszek sp.n. (Hymenoptera: Aphelinidae) are described. Both species are known so far only from desert lavender (Hyptis emoryi) in California, butare likely to be more widely distributed. Encarsia heratyi, a member of the Encarsia parvella-gvoup, is separated from apparently closely-related species in that group.
查看更多>>摘要：Pristapenesia asiatica sp. nov, is described and illustrated from two female specimens collected in China and Thailand. This species is readily recognized by the absence of a tubular radial vein in the fore wings. A key to world fossil and living species of Pristapenesia is provided. Pristapenesia was originally described .by Brues (1933) to accommodate P. primaeva, an Eocene fossil species from the Baltic region and based on a series of males and a single female "with extremely long, slender abdomenand prothorax much produced anteriorly". At that time he classified the genus in the Bethylidae. Subsequently, Prentice et al. (1996) described Dominibythus, which was later synonymized with Pristapenesia by Brothers and Janzen (1999), and properly assigned the latter to Scolebythidae. Two species were described m Dominibythus and later transferred to Pristapenesia, the Miocene fossil P. inopinata (Prentice & Poinar 1996) in Early Miocene amber from the Dominican Republic, and the extant P. striata (Azevedo 1999) from Brazil.
查看更多>>摘要：Terellia korneyevorum sp. nov., reared from flower heads of Echinops spp. is described from Iran. It is similar to T. tarbinskiorum Komeyev and T. bushi Komeyev in its mesonotum pattern and male genitalia structure, differing by its narrow, widely separated preapical and apical crossbands. The three species are separated from the quadratula group of species to form a new group; the diagnosis of the tarbinskiorum group of species is given. All the species of this group share presence of three pairs ofblack shining spots on the scutum, one on the transverse suture, one at the dorsocentral and one at prescutellar acrostichal seta base. They also share such a pattern with the species of Orellia Robineau-Desvoidy 1830, differing by the structure of malegenitalia and different host plants. A key to the species of tarbinskiorum group is given.
