Karnyothrips alpha Pitkin, 1976: 261–262 View in CoL .

This species was described from India based on six females and seven males collected mainly from bamboo. Unfortunately, specimens of it have not been available for this study. The following diagnosis is based on the original description and figures, but the conditions of the mesopresternum, prospinasternum and the terminal tube setae are uncertain. Moreover, Pitkin did not indicate the wing form of the type series, but possibly they are macropterae. The bicolored color pattern of this species is unique among the genus .

Diagnosis. Bicolored species, head and tube brown, thorax and abdominal segments I–IX largely yellowish; antennal segments I and VII–VIII brown, segments II–VI largely yellow, but VI with distal half brownish. Antennal segment VIII 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. Notopleural sutures complete. Fore wing without duplicated cilia. Tube about 0.5 times as long as head.
