Trichothyse hamipalpis ( Kroneberg, 1875) comb. nov.

Melanophora hamipalpis Kroneberg, 1875: 24 , plate II, fig. 3.

Leptodrassus hamipalpis (Kroneberg) : Simon, 1893: 363.

Echemus hamipalpis (Kroneberg) : Dalmas, 1919: 250.

Poecilochroa hamipalpis (Kroneberg) : Fomichev & Marusik, 2021: 448 , figs 22–29.

Remarks. The repository of the type (s) is unknown. They are not in the Zoological Museum of the Moscow State University ( Mikhailov 2018), in whose journal the species was described ( Kroneberg 1875), nor were they mentioned in subsequent taxonomic papers published since its description ( Simon 1893; Dalmas 1919; Fomichev & Marusik 2021). The illustrations of the palp provided in Fomichev & Marusik (2021: figs 22–27) are diagnostic and were used for comparison.

Description. Male. For description of the male, see Fomichev & Marusik (2021).

Female. Unknown.

Justification of transfer. Although we could not examine the holotype of P. hamipalpis , the illustrations of the palp provided for this species are diagnostic and present all typical features of the male Trichothyse species: distomedially originating broad conductor with prolateral fold, apically originating claw-like embolus with broad embolic base, medially contiguous sperm duct with single loop, and robust RTA with apical bifurcation (cf. Fomichev & Marusik 2021: figs 22–27 and Figs 1–8 , 54–55 , 109–112 , 116–117 ). Based on the similarity in genitalic structure and somatic morphology of this species to Trichothyse , we propose the transfer of P. hamipalpis .

Distribution. Known only from Tajikistan and Uzbekistan in western Asia ( Fig. 121 ).
