This bicolored species was described based on macropterous one female, micropterous three females and one male collected from dead branches in Amami Is., the Ryukyu Islands , and Kyushu, Japan. It is peculiar in having antennal segment III extremely short, and the maxillary stylets closer together medially .

Diagnosis. Bicolored yellow and brown; head and metathorax yellow, prothorax pale brown, mesothorax and abdomen largely yellow, but partly shaded with pale brown; all legs yellow; antennal segments I to III yellow, segments IV to VIII pale brown to brown. Antennal segment III extremely short; segment VIII slightly constricted at base; segments III and IV with two (1+1) and four (2+2) sense cones respectively. Maxillary stylets close together medially. Notopleural sutures complete. Mesopresternum divided into two lateral plates. Prospinasternum large, fan-shaped. Tergite IX S1 setae expanded, shorter than tube. Tube about 0.6 times as long as head; terminal setae 1.7–1.8 times as long as tube.

Specimen-examined. Japan, holotype macropterous female and paratype micropterous three females and one male (see Okajima 2006, p. 391).
