查看更多>>摘要：Sweta gen. n. is described and illustrated based on type species S. hallucinata sp. n. from northeast India and Thailand and placed in the typhlocybine tribe Dikraneurini. The new genus is unique among known Typhlocybinae in having the pronotum enlarged and extended to the scutellar suture. This feature is characteristic of the related subfamily Signoretiinae, but among other subfamilies is restricted to a few brachypterous forms.

The description includes all life stages: egg, larva, pupa and adult, and covers special structures such as the female bursa plates and male copulatory clamp. Details of habitat, male courtship flash patterns and male-female courtship behaviour are described. This species is the second in the genus Pteroptyx found to use a copulatory clamp, which functions to wedge the mating pair together. A complete clamp however does not appear necessary for successful insemination. Bursa plates hold the spermatophore partially projecting into a spermatophore-digesting gland. Other functions for the plates are investigated and discussed. The deflexed elytral apex appears after eclosion in the adult male. Mechanisms for the loss of ventrite 8 in the male abdomen are explored. A list of the 30 Pteroptyx species recognised here, with habitats, some morphological characteristics and a key to species of the Oriental Pteroptyx are provided.
查看更多>>摘要：Inclusion of the tribe Holochlorini has been questionable, for its complicated history and its controversial important diagnostic character about structure of tibial tympana. Here we briefly introduce its history and summarize its inclusion in the world and in China. We also introduce a newly recorded genus from China, Arnobia, and other two genera in the tribe, Psyrana and Phaulula, provide a list of Chinese species for the three genera, separately, together with the key to species of the three genera. At the same time, we describe seven new species to science in the Holochlorini, i.e., Arnobia hainanensis sp. nov., Arnobia guangxiensis sp. nov., Phaulula apicalis sp. nov., Psyrana magna sp. nov., Psyrana heptagona sp. nov., Parapsyra brevicauda sp. nov., and Sinochlora semicircula sp. nov. Diagnostic illustrations are presented.

Its subspecies S. tricerata compacta Evans, 1937 is raised to species rank. The host plant is Dalbergia armata (Fabaceae) and it is the only known member of the African Celaenorrhinini that does not have Acanthaceae as host-plant and the pupa is the only one known without a free proboscis sheath.

As with other anthocorid flower bugs, the members of the Cardiastethini prey on small arthropods. The predaceous habits of many anthocorids have attracted the attention of researchers who work in agro-ecosystems (e.g., biological control; Lattin 1999). The tribe Cardiastethini Carayon 1972 had been synonymized under the Dufouriellini Van Duzee 1916 (Stys 1975). Recently, Carpintero and Dellape (2008)transferred the genus Dufouriellius Kirkaldy 1906 (type genus for the tribe Dufouriellini) to the tribe Anthocorini Fieber 1836. Therefore, they reestablished the Cardiastethini (nom. restit), and proposed Dufouriellini as a junior synonym of the tribeAnthocorini Fieber 1836. Following this taxonomic change, all genera of the Dufouriellini, except for the Dufouriellius, were restored in the tribe Cardiastethini. After that revision, the Cardiastethini is now re-assigned at the tribal level, and is composed of 15 genera with a primarily tropical distribution (Carpintero and Dellape 2008).
