Both genera are of Asian\/Indomalayan origin, the latter with a diversity hotspot in the subtropical valleys of the Himalayas. Based on morphological data, we propose three new species of <jats:italic>Epeus<\/jats:italic> (<jats:italic>Epeus daiqini<\/jats:italic> sp. nov. (\u2642\u2640), <jats:italic>Epeus pallidus<\/jats:italic> sp. nov. (\u2640), <jats:italic>Epeus szirakii<\/jats:italic> sp. nov.

Additionally, we redescribed <jats:italic>E<\/jats:italic>. <jats:italic>tener<\/jats:italic> (Simon, 1877) and added photographs of morphological characters. The genus <jats:italic>Ptocasius<\/jats:italic> is redefined due to the inclusion of 37 species, previously included in <jats:italic>Yaginumaella<\/jats:italic> Pr\u00f3szy\u0144ski, 1979.
