Raveniola afghana Zonstein, 2024, sp. nov.

Raveniola afghana sp. nov. urn:lsid:zoobank.org:act: 4CC0D56D-66E1-4890-8A23-AC5529B927BB Figs 37, 111, 167, 230, 310, 489–490, 559, 750 Anemesia tubifex – Denis 1958: 82 (♀; misidentified, not Nemesia tubifex Pocock, 1889). Raveniola sp. aff. concolor – Zonstein 2018b: 48 (♀). Diagnosis The new species shares with Raveniola alajensis sp. nov., R. hirta sp. nov. and R. karategensis sp. nov. the presence of modified long hairs on the female tibia and metatarsus IV (Fig. 310 cf. Figs 311, 314, 316–317). Females of R. afghana sp. nov. are well distinguishable by the long twisted branches of their spermathecae vs dissimilarly arranged spermathecal branches in all other species included in the same group known from females (Figs 489, 490 cf. Figs 491–525). Etymology The specific epithet is derived from the name of the country (among the meanings of ‘Afghan’, one corresponds to a native or inhabitant of Afghanistan); the gender is feminine.

F-shaped, with moderately low and narrow bases broadly spaced from each other, each with two long, narrow, diverged and twisted stalks, and slightly dilated inner and outer terminal heads (Fig. 490). SPINNERETS. See Fig. 559. PMS: length 0.83, diameter 0.39. PLS: maximal diameter 1.04; length of basal, medial and apical segments 1.90, 0.97, 0.91; total length 3.78; apical segment triangular. Male Unknown. Variation Carapace length in females (n =8) varies from 9.31 to 11.96. The variation in the shape of the spermathecae as shown in Figs 489–490. Ecology The species inhabits woodless slopes in the alpine zone at an altitude of 3000–3400 m a.s.l. According to Denis (1958), the spiders were collected from their burrows with an open (unprotected) entrance. Distribution Central Afghanistan: Koh-i-Baba Mts. See Fig. 750. Notes Denis (1958) estimated the carapace length in the collected females as ranging from 10 to 14 mm. The measured actual length of the carapace in these females is somewhat shorter, as noted above.
