Diagnosis
In the structure of its embolus, this species is similar to Raveniola arthuri, but differs from the latter by having a considerably longer and less wide proximal part of the embolus (Figs 187–188; cf. Fig. 184). In the shape of their spermathecae, however, females of R. micropa resemble those of R. zaitzevi from another species group (the female of R. arthuri is unknown), differing from them in having noticeably broader spermathecal bases and shorter median and smaller lateral receptacles (Figs 206–207; cf. Figs 208–209).
