Karnyothrips nigriflavus Ramakrishna, 1934: 496 View in CoL .

This species was described from Coimbatore, India, based on ‘numerous specimens’ collected on bamboo and possibly of the macropterous. Unfortunately, the type specimens have not been available in this study, but one female and one male identified by Ananthakrishnan as this species were examined. The bicolorous color pattern of this species is unique in Asian species of the genus .

Diagnosis. Bicolorous species ( Fig. 152 View FIGURES 152–157 ); head, prothorax and tube brown, the rest of body largely yellow; legs yellow, but fore femora brownish in male; antennal segments I–II and VII–VIII brown, III–VI yellow. Antennal segment VIII conical ( Fig. 156 View FIGURES 152–157 ), not constricted basally; segments III and IV with one (0+1) and three (1+2) sense cones respectively. Maxillary stylets about one-fifth of head width apart ( Fig. 153 View FIGURES 152–157 ). Notopleural sutures complete or almost complete. Mesopresternum reduced, divided into two lateral triangular plates; prospinasternum large. Tergite IX S1 setae expanded, shorter than tube, S2 pointed, longer than tube. Tube ( Fig. 154 View FIGURES 152–157 ) a little longer than 0.5 times as long as head; terminal setae about 1.5 times as long as tube.

Specimens-examined. India, 1 female (mac.) and 1 male (mac.), Palghat, on bamboo, 28.ix.1965, T. N. Ananthakrishnan .
