Most physical descriptions on Troutnut are direct or slightly edited quotes from the original scientific sources describing or updating the species, although there may be errors in copying them to this website. Such descriptions aren't always definitive, because species often turn out to be more variable than the original describers observed. In some cases, only a single specimen was described! However, they are useful starting points.
Abdominal tergites of male imago brown, sternites pale yellowish white; venation wholly pale.
Head and thorax brown; thoracic sternum pale brown. Legs pale yellowish white. Wings hyaline, venation wholly pale. Abdominal tergites brown; sternites pale yellowish white, contrasting strongly with the dark upper surface. Forceps yellowish white. Tails whitish, not darker at joinings.
The nymph has lateral but no dorsal spines on the mesonotal shield; the genae are not produced into spines; the frontal projections are small and rounded. The lateral mesonotal spines are very long and sharp. This species is distinguished from others in the genus by the wholly pale venation and the striking contrast in color between the dorsal and ventral surfaces of the abdomen.
