Figs 88, 121, 203, 221, 235
Diagnosis
The holotypic female differs from females in other species of the same group by having long and wide, highly arched spermathecae with median and lateral receptacles located ventrally (not laterally as in other species, Fig. 203; cf. Figs 198–202).
Etymology
The specific epithet is a patronym honoring Dr. Sinan Anlaş, a Turkish entomologist and a friend of the authors.
Material examined
Holotype TURKEY: ♀, Siirt province, Baykan District, ca 10 km NE of Baykan, 38°10′29.64″ N, 41°49′20.06″ E, 738 m, 18 May 2009, E.A. Yağmur and M. Uslu leg. (AUZM).

SPERMATHECAE. Very long and wide, strongly arched, with receptacles set close to each other on ventral sides of spermathecae (Fig. 203).
SPINNERETS. PMS: length 0.44; diameter 0.17. PLS: maximal diameter 0.40; length of basal, medial and apical segments 0.80, 0.55, 0.48; total length 1.83; apical segment shortly digitiform.
Male
Unknown.
Ecology
The female holotype was collected in an open steppe biotope covered with shrubs (Fig. 231). The only known representative of this species was found inhabiting a shallow and weakly lined cavity under a stone (Figs 232–235).
Distribution
Known only from the type locality.
