Hoplandrothrips coloratus Okajima

Hoplandrothrips coloratus Okajima, 2006 , 311–312.

Described from the Ryukyu Islands (Ishigaki Is. and Iriomote Is.), Japan, this species was recorded subsequently from Taiwan ( Dang & Qiao 2014). Most specimens of the type series were collected from subtropical forest litter. It has the head entirely reticulate dorsally, the sub-basal cheek setae small, antennal segment VIII pedicellate with the base distinctly constricted, the fore tarsal tooth minute in female, the pelta with rather slender lateral wings, the intermediate seta between S1 and S2 on the tergite IX rather long, and sternite VIII of males with no pore plate. Because these character states are shared, this species may be closely related to H. flavipes together with H. brunneicinctus from Australia and H. aseanae newly described above from Southeast Asia (they are named tentatively flavipes -group here). However, flavipes has four stout sense cones on antennal segment III, whereas coloratus has unusually only two sense cones on that segment. However, brunneicinctus and aseanae have morphological structures something intermediate between coloratus and flavipes with three sense cones on the antennal segment III. In addition to this species, at least three species, such as H. elongatus from Japan, H. hemiflavus from Australia and H. tumiceps from New York, North America, also have only two sense cones on antennal segment III, but these species may be not closely related to each other. Unfortunately, specimens from Taiwan have not been available for this study.
