Identification

In much of its range, mature males of T. furva are easily confused with those of the similar T. dorsalis. The key difference between the species is the shape of the hamule of the secondary genitalia. Also, in most specimens of T. furva, the outermost antenodal cross-veins do not cross the subcostal vein to join the radial vein, whereas in T. dorsalis they do.[2]
