Review of Chirothrips and related genera (Thysanoptera: Thripidae) of the Americas, with descriptions of one new genus and four new species.

The species of Chirothrips and related genera occurring in the Americas are reviewed. Seventeen species from the area are retained in Chirothrips , 15 species are treated in Arorathrips, two species in Konothrips, one species in Oelschlaegera and one species in the new genus Unilobothrips. The generic concepts of the four previously described genera are revised. Four new species, Arorathrips childersi, Chirothrips hemingi, Konothrips colei, and Unilobothrips cornuatus are described. Chirothrips moultoni Post is synomymized with C. aculeatus Bagnall, and C. spinosus Moulton with Arorathrips texanus (Andre). The following new combinations are proposed: Arorathrips crassus (Hinds), A. crenulatus (Hood), A. dorsalis (Hood), A. lenape (Hood), A. oneillae (Watts), A. sericatus (Hood), A. texanus (Andre), A. vestis (Hood) and Oelschlaegeria priesneri (Hood) (all from Chirothrips ). Chirothrips mongolicus zur Strassen is returned to Chirothrips from Arorathrips. Identification keys to genera and species, and known distributions of the species, are provided.
