The Old-World genus Ceratothripoides (Thysanoptera: Thripidae) with a new genus for related New-World species

摘要

A key is provided to five Old World species that comprise the genus Ceratothripoides Bagnall, and the species C. revelatus (Priesner) is recalled from synonymy with C. brunneus Bagnall. Five New World species previously placed in this genus are here allocated to Retanathrips Mound & Nickle gen.n., with Physothrips funestus Hood as type species. The genus Ceratothripoides was proposed by Bagnall (1918a) for one African species from Ghana, based on a single female specimen with distinctive antennae. Subsequent collecting indicated that the antennae of this specimen were deformed, and the species was discovered in several additional African countries. Since 1918, fourteen more species have been described in, or referred to, Ceratothripoides, although six of them have been placed into synonymy. Full nomenclatural information concerning all of these taxa is available in the web-based checklist to world Thysanoptera (Mound 2009a). However, the genus itself has remained poorly defined. Mound & Marullo (1996) discussed the five New World species that have been referred to this genus, but listed them as "Ceratothripoides", indicating that these five were not congeneric with the Old World species. As a result these five species have remained with no formalgeneric assignment.
