Diagnosis
The structure of the spermathecae of Raveniola nana sp. nov. resembles that of R. turcica sp. nov. (the female of R. birecikensis sp. nov. is unknown), but differs in having the median and lateral receptacles situated considerably closer to each other (Fig. 204; cf. Fig. 205). Additionally, R. nana sp. nov. is considerably smaller and has a paler coloration than both the latter species.
Etymology
The specific epithet (a variable adjective from Ancient Greek νᾶνος, meaning ‘dwarf’) refers to the very small size of this species.

SPERMATHECAE. Moderately broad with receptacles close to each other (Fig. 204).
SPINNERETS. PMS: length 0.36; diameter 0.16. PLS: maximal diameter 0.31; length of basal, medial and apical segments 0.55, 0.35, 0.34; total length 1.24; apical segment shortly digitiform.
Ecology
The holotypic female was found in open forest under a stone.
Distribution
South-Eastern Turkey (Fig. 221).
Note
There is a possibility that the holotype of Raveniola nana sp. nov. is the unknown female of the allopatric R. biresekensis sp. nov. However, both these species differ in size and colouration (R. nana sp. nov. is noticeably smaller and considerably paler than the latter species), as well as in the relative size of AMEs and PMEs (larger vs smaller, respectively). We thus prefer to consider these names as belonging to different species, until the currently missing males of R. nana sp. nov. and the unknown females of R. biresekensis sp. nov. are collected and identified.
