Comments
The species of Trichiusa are currently under revision by V. Gusarov and so Trichiusa compacta is currently best recognized by the combination of habitus and the following sexual characters: median lobe of aedeagus in lateral view with tubus narrow, evenly subparallel and narrowly rounded apically (not sharp) (Fig. 156); spermatheca with moderately large, spherical and basally narrowed capsule bearing a deep apical invagination, stem C-shaped, looped and twisted posteriad (Fig. 157).
Trichiusa compacta appears to be forest inhabiting and was collected from a variety of passive traps and by sifting litter near vernal and semi-permanent forest pools.
