Remarks. Uchida & Isobe (1988) redescribed this small brown species in all life stages. Males have an acute, straight or slightly curved, usually pigmented spur on the basal cercal segment and the inner margin of this segment bears a fringe of setae along the apical half of the segment. The female forewing length is generally less than 11 mm and the egg has a distinctive “pine cone” appearance ( Figs. 1-4 View Figs ).
