Figs 135–147
Gen.n. Om6: Eberle et al. 2018 (molecular data); Huber et al. 2018: fig. 2.
Type material. OMAN: ♂ holotype, ZFMK (Ar 20623), Ash Sharqiyah South, rock desert between Sur and Kamil (22.4616°N, 59.3870°E), 95 m a.s.l., 18.ii.2018 (B.A. Huber).
Other material examined. OMAN: 1♂, ZFMK (Ar 20624), and 3♀ 1 juv. in pure ethanol, ZFMK (Om118), same data as holotype. 4♂ 4♀, ZFMK (Ar 20625), and 2♀ 2 juvs in pure ethanol, ZFMK (Om29), same locality at 22.462°N, 59.388°E, 90 m a.s.l., under rocks in desert, 23.iii.2017 (B.A. Huber).
Etymology. The species name is an adjective, Latin velox = swift, quick, fast, and refers to the rapid running of this species.
Diagnosis. Males are easily distinguished from other Old World Ninetinae (representatives of Ninetis) by distinctively curved procursus (Figs 143–144; left palp in dorsal view: clockwise); also by absence of pair of anterior humps on male sternum (Fig. 145) and by short prolateral apophysis on male palpal femur proximally (Fig. 143). Females with trapezoidal anterior epigynal plate with slightly protruding anterior part provided with stronger hairs, and internal genitalia with pair of small dark receptacle-like structures and larger transparent median sac (Figs 142, 147).
Description. Male (holotype). MEASUREMENTS. Total length 0.97, carapace width 0.43. Distance PME-PME 40 µm; diameter PME 50 µm; distance PME-ALE 20 µm; distance AME-AME 10 µm, diameter AME 30 µm. Leg 1: 2.07 (0.60 + 0.13 + 0.57 + 0.50 + 0.27), tibia 2: 0.45, tibia 3: 0.42, tibia 4: 0.60; tibia 1 L/d: 8.8.
COLOR (in ethanol). Prosoma and legs pale ochre-yellow. Abdomen monochromous pale ochre-gray.
BODY. Habitus as in Figs 135–136, 138–139. Ocular area barely elevated; thoracic furrow absent; clypeus barely modified, slightly bulging (Fig. 146). Sternum slightly wider than long (0.30/0.28), unmodified.
CHELICERAE. With pair of pointed frontal apophyses and stridulatory ridges (Figs 145–146).
PALPS. As in Figs 143–144; coxa unmodified, trochanter with low ventral process; femur proximally with short prolateral apophysis proximally; tibia globular, procursus distinctively curved towards prolateral (circular in dorsal view); bulb with slightly sclerotized ventral apophysis and semitransparent dorsal process (presumably carrying opening of sperm duct—not seen).
Legs. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium of tibia 1 at 54%; tibia 1 without prolateral trichobothrium (present on other tibiae); tarsus 1 with few pseudosegments (~4, poorly visible in dissecting microscope).
Male (variation). Tibia 1 in 5 other males: 0.47–0.53 (mean 0.49).
Female. In general similar to male (Fig. 137), but clypeus not bulging. Tibia 1 in 9 females: 0.45–0.60 (mean 0.52). Epigynum simple externally (Fig. 140), trapezoidal anterior plate with variably distinct and slightly protruding anterior part provided with stronger hairs, short posterior plate. Internal genitalia with pair of small dark receptacle-like structures and larger transparent median sac; apparently without pore plates (Figs 142, 147).
Distribution. Known from type locality only (Fig. 342).
Natural history. This species was found in a rocky desert (Fig. 339), under rocks and small stones. When disturbed, it ran away very quickly. In small glass vials it built flimsy webs with small platforms on which the spider rested.
