The male genitalia of " T . sensilis " are symmetrical and overall only lightly sclerotized ( hardened ) except for the stout aedeagus, which has a heavily sclerotized rod on the underside.

An "'aedeagus "'( plural "'aedeagi "') is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female insect.
33.
It appears to resemble " Enteucha " in various ways, such as the shape of the valva and uncus, the absence of a transverse bar of the transtilla and possibly the thickening in the aedeagus.
34.
In advanced groups of insects, the male uses its aedeagus, a structure formed from the terminal segments of the abdomen, to deposit sperm directly ( though sometimes in a capsule called a " spermatophore " ) into the female's reproductive tract.

Features of the adults which are more or less exclusive to this subfamily are the male genitalia which have an elongate, strap-like valve with a simple corona in conjunction with an aedeagus vesica that is often spiralled and tending to have isolated or small clusters of cornuti ( Hardwick, 1970 ).
37.
The aedeagus is part of the male insect's phallus, a complex and often species-specific arrangement of more or less sclerotized ( hardened ) flaps and hooks which also includes in some species the valvae ( clasper ), which are paired organs which help the male hold on to the female during copulation.
38.
Diagnostic features are : uniformity, rather than asymmetry, of the rings of the ocelli; an undivided, dorsally domed uncus in the male genitalia; a short broad aedeagus with two apical fields of scobination, and a densely and robustly scobinate apex to the conical vesica; strong pouches lateral to the ostium in the female genitalia; a signum consisting of a single spine in the bursa copulatrix.
