Hoplothrips Amyot & Serville

( Fig. 62 )

Hoplothrips Amyot & Serville, 1843: 640 . Type species: Thrips corticis De Geer , by subsequent designation of Karny, 1912a.

This is a large genus of 128 fungus-feeding species. As in Hoplandrothrips , many of these are known to exhibit sexual dimorphism as well as male allometry, leading to problems both in defining the genus and in distinguishing the species. These two genera are probably more closely related to each other than previous authors have considered (Mound et al. 2013). In the north temperate part of the world, Hoplothrips species are often common on dead branches, with six species recorded from China, but only a single one listed from Indonesia.

Diagnosis: Often sexually dimorphic, also wing-length polymorphic; head usually slightly longer than wide; postocular setae usually well developed ( Fig. 62 ), pointed or capitate; stylets usually long and close together medially; antennae 8-segmented, VIII usually constricted basally, III with 3 sensoria, IV with 4; pronotum with major setae variable, notopleural sutures usually complete, sometimes incomplete or nearly complete; basantra absent, rarely present; mesopresternum variable, often divided into three plates; sternopleural sutures present; fore tarsal tooth usually present in both sexes; fore wings if present parallel-sided, with duplicated cilia; pelta usually bell-shaped; tergites II–VII usually each with 2 pairs of wing retaining setae; tube variable in shape, anal setae usually shorter than tube, often longer; male sternites often with paired reticulated areas, sternite VIII with pore plate.
