Terthrothrips Karny

Terthrothrips Karny, 1925: 78 .

The genus Terthrothrips is a member of the Glyptothrips lineage (Okajima, 2006), an informal assemblage of taxa within the Phlaeothripinae that has previously been referred to as a weakly defined tribe Glyptothripini (Priesner, 1961; Mound, 1977). The genus was established by Karny for a single species from Brazil, Phlaeothrips sanguinolentus Bergroth. Currently 25 species are listed in the genus (Mound, 2010), all from the New World apart from three that are described from Japan (Kudô, 1978; Okajima & Urushihara, 1992; Okajima, 2006). No member of the genus has been reported previously from China.

Diagnosis. Polymorphic species with macropterous, micropterous and apterous adults. Head longer than wide, dorsal surface strongly or weakly sculptured, produced in front of eyes; eyes usually large; postocular setae welldeveloped with apex expanded; antennae long and slender, maxillary stylets short, usually wide apart and V-shaped in head; pronotal anteromarginal (am) and anteroangular (aa) setae reduced or well developed, rarely aa and am setae both greatly reduced; fore tarsal tooth present in both sexes; fore wing if developed, almost parallel sided, without duplicated cilia (Karny, 1925; Okajima, 2006).
