Comments
This species is currently recognizable only by the combination of habitus (Fig. 77) and the following sexual characters: median lobe of aedeagus in lateral view with tubus narrowed toward apex and sharply pointed apically (not rounded) (Figs 158–159); spermatheca with large, spherical and basally narrowed capsule bearing a small apical invagination, stem relatively straight, looped and twisted posteriad (Fig. 160).
Unlike Trichiusa robustula, Trichiusa hirsuta was collected from upland forested or semi-forested habitats on sandy soil. More collections will help elucidate the habitat requirements of this species.
