(Hymenoptera: Eulophidae: Entedoninae), is described from the northern part of the Neotropical region, from Costa Rica to Ecuador and Brazil, and the Caribbean (Trinidad & Tobago), It comprises eleven new species: D. alveum, D. ambonatum, D. apertum, D. apon, D. crassicornis, D.jimenezi, D. mischum, D. noyesi, D. pinguicornis, D. pnigaliae, D. quadrifer. These species are diagnosed, described and illustrated, and a key for their identification is provided. Dentalion is characterized by two putative autapomorphies and two synapomorphies. The phylogenetic implications of these apomorphies are discussed briefly.
查看更多>>摘要：The taxonomic position of some of the Binna-like species of Afrotropical Spilosoma Curtis (1825) and Radiarctia Dubatolov (2006) are reviewed. Historical and current problems associated with determining taxa by comparison with old or faded type material are highlighted. A new genus Pseudoradiarctia is established for P. rhodesiana comb, nov., P. lenti-fasciata comb, nov., P. afflnis comb, nov., and P. scita comb. nov. A new rank is proposed for and subspecies is described in Radiarctia screabile, andthree new species are described in Pseudoradiarctia. R. screabile (Wallengren) and Binna penicillata Walker (1866) are redescribed. Lectotypes are designated fox rhodesiana, lentifasciata, affinis and scita. Notes on a defence mechanism of screabile arepresented.

Both new species induce galls on Quercus bumelioides Liebm. (Fagaceae, sect. Quercus, White Oaks). The diagnostic characters, gall descriptions, distribution, biological data and a key for the identification of the new species are given. The new species represent the first records of the genus Loxaulus outside North America.
查看更多>>摘要：Lithohypna chifengensis, new genus and species of the family Glaphyridae MacLeay, 1819 is described and illustrated from the Lower Cretaceous Yixian Formation of Liutiaogou of Inner Mongolia, China. The extant Glaphyridae MacLeay, 1819 is comprised ofabout 200 species and subspecies in six genera (Carlson 2002; Nikodym 2005; Nikodym & Bezdek 2006; Nikodym & Keith 2007; Keith 2007, 2008a, 2008b; Keith & Uli-ana 2008; Sabatinelli & Uliana 2009; Uliana & Sabatinelli 2010). Most extant Glaphyridae genera are restricted to the Palaearctic (Medvedev 1960). The Nearctic region is home to only nine species within a single endemic genus, Lichnanthe Burmeister, 1844 (Carlson 2002). Species of the genus Amphicoma Latreille, 1807 occur in the Palaearctic and Oriental regions. The South American tribe Lichniini Burmeister, 1844 (Scarabaeidae: Melolonthinae) was recently transferred out of the family Glaphyridae based on morphological and DNA analysis (see Hawkins 2006).
查看更多>>摘要：A new subgenus of Ischalia, Nitidischalia, and new species, Ischalia (Nitidischalia) barclayi, is described and illustrated from Sabah, Malaysia. Subgeneric concepts are discussed and an updated world checklist of subgenera and species is presented. Arevised key to the Southeast Asian Ischalia species exhibiting blue elytra is also presented, as is a key to the subgenera of Ischalia.Due in part to a number of autapomorphies expressed by both larvae and adults, Nikitsky (1992) proposed elevating members of Ischalia to familial status. Until a more thorough phylogenetic analysis of heteromerous Coleoptera is completed, the question offamilial placement for Ischalia will remain open. However, the position of Nikitsky has been followed in recent publications, including this paper.

查看更多>>摘要：The new genus Striatovertex is described to accomodate a distinct group of eucoiline wasps (Hymenoptera: Cynipoidea: Figitidae) currently included in the nominate genus Eucoila Westwood, but known among specialists to not belong there for decades. They are characteristically large wasps with reduced wing pubescence, parasitizing dung-breeding Diptera, and are common in North and South America, but also present in Australia and Hawaii. Their diagnostic characters place them in what is currently Ganaspini rather than very close to Eucoila in Eucoilini, and this has been confirmed by earlier phylogenetic analyses. Diagnostic and other distinctive characters are reviewed, and thirteen new combinations are made for species belonging to this group.
查看更多>>摘要：A single species of the nominate genus Buprestis Linnaeus 1758 (Coleoptera: Buprestidae) was described from South America: B. bruchi Obenberger 1928. Recently, in response to a request, images of the type specimen (Fig. 1) and attendant labels were sent by colleagues at the Museo Argentino de Ciencias Naturales, Buenos Aires, Argentina, where the type is housed. Although subgeneric placement was not given in the recent world catalogue (Bellamy 2008), it is clear from this photograph that it should beplaced in the subgenus B. (Cypriacis) Casey 1909 and in fact is conspecific with B. striata Fabricius 1775. The two color forms of B. striata (Figs. 2, 3) are from specimens in the first authors' collection.
