查看更多>>摘要：The family Baetidae is still poorly known from Venezuela, particularly in the South of this country. Three field trips were carried out in La Gran Sabana region (Bolivar State). As a result of these trips, four genera {Cryptonympha, Harpagobae-tis, Spiritiops and Zelusid) and nine species are reported for the first time from this region. A discussion of each taxon is included as well as drawings when it is necessary. Keys with all known genera of Baetidae and all known species of Cam-elobaetidius from Venezuela are included too. With this analysis, the number of the genera and species reported is duplicated improving the knowledge of this family from this country.

查看更多>>摘要：This paper describes the nymphal development of Ceroplastes janeirensis (Gray), which develops its wax test differently to that currently known for other Ceroplastinae. Macroscopic and microscopic characters of the three immature female stages are described and illustrated for the first time. An identification key to the female instars is provided and a brief discussion is also included comparing their morphology with those of other Ceroplastinae.
查看更多>>摘要：We review and update species of Coenagrion recorded from China, including distributional information. A key to the males is provided including figures of the genital ligula and caudal appendages. A distributional record of Coenagrion armatum is excluded from China. Coenagrion bifurcatum Zhu & Ou-yan, 2000, is assigned as a junior synonym of Coenagrion johanssoni (Wallengren, 1894). Coenagrion chusanicum Navas, 1933 is assigned as a junior synonym of Par-acercion hieroglyphicum (Brauer, 1865). Coenagrion dorothea Fraser, 1924 is newly combined as Paracercion dorothea (Fraser, 1924) comb. nov. Coenagrion impar Needham, 1930 and Cercionyunnanensis Zhu & Han, 2000 are both treated as junior synonyms of Paracercion dorothea. Coenagrion holdereri (Forster, 1900) is redescribed here based on fresh specimens.

Yemmatropis hsiaoi sp. nov. and Yemmatropis nigrovittatus sp. nov. are described. Photographs of head and pronotum and drawings of openings of male genital capsules and parameres of all four species, and a key to all Yemmatropis species, are provided to assist in identification. The type specimens of the new species are deposited in the Institute of Entomology, College of Life Sciences, Nankai University, Tianjin, China.

查看更多>>摘要：The generic name Wulpisca Lopes is placed as a junior synonym of a redefined Panava Dodge, a Neotropical taxon characterized by short apical spines on the male surstylus, a single phallotreme, presence of proclinate frontorbital bristles in the male,and setose wing vein Rr The species W. imbecilla (Wulp) and W. arnaudi Lopes are transferred to Panava and a new species, P. amazonica sp. nov., is described from Brazil. A key to males of the seven species of Panava is given. The subgenus Bezzisca Lopesof the predominantly Neotropical genus Dexosarcophaga Townsend comprises 17 species, including a new one described herein, D. (B.) tracua sp. nov. from Brazil. The key to species of D. (Bezzisca) by Silva and Mello-Patius (2010) is modified to include this new species.
查看更多>>摘要：Larvae of Potamophilops cinereus (Blanchard, 1841) from Brazil, Sao Paulo, Ribeirao Grande (Fazenda Intervales, Rio Carmo) are described for the first time and illustrated. The larvae were found associated with adults. The larva of P. cinereus is mostsimilar to larvae of species of the Mexican and Central American genera Disersus Sharp and Hispaniolara Brown, but can be easily distinguished chiefly by the head being not visible when seen from above, due to being concealed by the anterior projectionof the pronotum. Comparisons of the three genera are presented. Photographs of the adult habitus of P. cinereus are also furnished. A key to the larvae of the genera of Larainae of Brazil is included.
