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.

Each cheliceral furrow with 9 promarginal teeth and 9 mesobasal denticles. Maxillae with 9–10 cuspules each.

LEGS. Scopula: distal on metatarsi I–II, narrowly divided on tarsus I and palpal tarsus, widely divided on tarsus II, elsewhere absent. Trichobothria: 2 rows of 8–9 each on tibiae, 12–14 on metatarsi, 11–13 on tarsi, 9 on palpal tarsus. Paired tarsal claws I–IV: outer and inner margins with 7–8 teeth each. Palpal claw with 4 teeth on inner margin.

LEG MEASUREMENTS.

SPINATION. Palpal femur and femora I–II with 4–5 dorsal bristles (weak spines) arranged in longitudinal dorsal row; femora III–IV with one basodorsal spine and 3–4 dorsal bristles; palpal patella and patellae I–II aspinose. Palp: femur pd1; tibia p1–1, v1–2–3; tarsus v2–0–0. Leg I: femur pd1; tibia v1–1–2; metatarsus v2(3)–2–2. Leg II: femur pd1; tibia v1–1–2(3); metatarsus v2–2–2. Leg III: femur pd0–0–1, rd0–0–1; patella p1, r1; tibia d1–0–0, p1–1, r1–1, v2–2–3; metatarsus d1–1–0, p1–1–1–1, r1–1–1–1, v2–2–3.

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.
