The oil-collecting structures of these bees are situated on the forebasitarsus and show interspecific variation related to the type of flower they visit (Roig Alsina 1997; Cocucci et al. 2000).

Although serious outbreaks of the tea-infesting whitefly in China, Taiwan and Japan have been attributed to this species overthe last 20 years, recent research has shown different host preferences between the two whiteflies. Hence, the two pests have tentatively been differentiated as tea-infesting and citrus-infesting populations. We further compared morphological, acousticand genomic features between the two populations in Japan. Morphological differences were recognised in the arrangement of spines, porettes and papillae on the dorsal disc and number of marginal crenulations and marginal waxy fringe of 4th-instar nymphs,as well as wing maculation and genitalic organs of adults. In courtship behaviour, the acoustic properties of male vibratory signals also differed between the two. Furthermore, genetic analysis of mtCOI sequences (759 bp) showed that the tea-infesting population was clearly distinct from the citrus-infesting group, with high bootstrap values. The mtCOI sequence identities were 76.2% between the two populations. Genetic differentiation between the two populations was shown by the high value (0.99650) ofpairwise Fst, indicating the sexual isolation of the two populations. Consequently, these two populations are regarded as different representatives, consisting of a sibling relationship, but clearly distinguished from each other as independent genomic populations. Here, we describe the tea-infesting population and propose a new scientific name, Aleurocanthus camelliae Kanmiya & Kasai sp. nov., and a new common name, camellia spiny whitefly, thus distinguishing it from A. spiniferus (Quaintance), the citrus spiny whitefly that constitutes the citrus-infesting population.
查看更多>>摘要：Species of the genus Scolothrips are re-assessed based on examination of type material together with many other specimens, and a key is provided to identify the 14 species recognised. The possibility is discussed that the three North American species,hoodi, pallidus and sexmaculatus are colour variants of a single species. Three apparently Old World species, dilongicornis, longicornis and takahashii, cannot be distinguished satisfactorily. Three new synonyms are established: quadrinotata is a synonym of asura; hartwigi is a synonym of brevipilis; priesneri is a synonym of takahashii. Two species from the Canary Islands are considered nomina dubia: quadrimaculatus and lanzarotensis. Two species are here recorded for the first time from Australia, latipennis and rhagebianus, and Australian records of sexmaculatus are considered to be based on misidentifications.
查看更多>>摘要：Brachodidae are a small family of fewer than 140 described species that are distributed worldwide except in North America. They reach their greatest diversity in the tropical regions of Asia and South America; however, many species occur in the Palaearctic region and in Australia, but these are restricted to a small number of genera. More than 40 species are known from the Oriental region and many more await description (Kallies 1998, 2000, 2004). We recently described a new species of Nigilgia Walker, 1863 (Phycodinae) from the Nanling Mts. in the province of Guangdong, China, and briefly discussed the Brachodidae known from China (Kallies et al. 2007). Here we describe a striking new species of Phycodes Guenee, 1852 from Guangdong that shows somesimilarities with Phycodes maculata Moore, 1881 from northeastern India. The new species can be readily distinguished from the latter and all other congeners by the distinct orange spots on the forewings.

Twenty species are recorded from Brazil, and three of them from Rio de Janeiro State. Here three new species of Cylloepus are described—Cylloepus quinquecarinatus sp. nov., Cylloepus nessimiani sp. nov., and Cylloepus friburguensis sp. nov. All were collected in the Rio Macae Basin, Rio de Janeiro State, southeastern Brazil.
