Diagnosis

The only known pair of Raveniola concolor clearly differs from all other congeners belonging to the same species group by their uniformly dark brown body and legs (seen in dorsal aspect) vs an ornamented abdomen, or palps and legs lighter than the carapace. In having a similar body size and proportions of the male leg I (see Figs 262 View Figs 256–264 and 271–272 View Figs 265–273 ), this species resembles P. pamira sp. nov. However, the holotype male differs from males of the latter species in possessing a considerably longer and more sharply twisted distal section of the embolus ( Fig. 388 View Figs 379–388 cf. Figs 418–428 View Figs 418–428 ), while the paratype female can be distinguished from females of P. pamira in having dissimilarly conformed spermathecae, with considerably higher and narrower bases ( Fig. 494 View Figs 487–503 cf. Figs 520–523 View Figs 504–521 View Figs 522–536 ).
