Description. Male and female. For description of the male and female, see Levy (1999).

Justification of transfer. The illustrations of the male and female genitalia in Levy(1999:figs 6–9) are diagnostic and were used for comparison. Even though we did not examine the types of P. senilis, subsequent illustrations of its genitalia are diagnostic and share all of the diagnostic features of male and female Trichothyse species, instead of Poecilochroa sensu stricto and Macarophaeus: distomedially originating broad conductor with prolateral fold, apically originating claw-like embolus with broad embolic base, medially contiguous sperm duct with single loop, robust RTA with apical bifurcation, epigyne with median extension and vulva with short copulatory ducts, large, bean-shaped primary, and small secondary spermathecae (cf. Figs 1–20, 54–57, 109–119 and Levy 1999: figs 6–9). Based on these observations, we propose transferring P. senilis to Trichothyse .

Distribution. Known from Asia, Africa and Europe (Fig. 121). This is the only Palaearctic species that has a distribution extending into Africa.
