Diagnosis
Within the concolor species group of Raveniola , the holotype male of R. hirta sp. nov. is well distinguishable, because it possesses the shortest embolus, compared to other species ( Figs 400–402 View Figs 400–408 cf. Figs 385–399 View Figs 379–388 View Figs 389–399 , 403–428 View Figs 400–408 View Figs 409–417 View Figs 418–428 ); it also has long modified hairs on the tibia and metatarsus IV, as shown in Fig. 313 View Figs 310–318 (vs their presence in those species, where these hairs are known, only in females).Considering the last character, this new species shares with R. afghana sp. nov., R. alajensis sp. nov. and R. karategensis sp. nov. the presence of long modified hairs on the female tibia and metatarsus IV. Females of R. hirta can be distinguished from those of R. alajensis and R. karategensis by having a uniformly coloured (vs fairly ornamented) abdomen ( Figs 42 View Figs 36–44 , 67–68 View Figs 63–68 cf. Figs 38, 44 View Figs 36–44 , 65 View Figs 63–68 ), and from those of R. afghana sp. nov. in possessing much shorter spermathecae provided with clearly wider inner branches ( Figs 504–508 View Figs 504–521 cf. Figs 489–490 View Figs 487–503 ).
Etymology
The specific epithet is an adjective referring to a hirsute (Latin: ‘ hirt-us/-a/-um ’) leg IV in this species, densely covered with elongated fine hairs in females and to a lesser extent in males; the gender is feminine.
