Ranops tharinae   sp. nov.

Figures 4 View FIGURE 4 A–D, 5A–C, 6A –C

Diagnosis. Males of R. tharinae   sp. nov. are recognized by the shape of the MA, with a widened incurved tip ( Figs 5A View FIGURE 5 , 6A View FIGURE 6 ), and a long distal tegular apophysis accompanying the E. The female is characterized by the epigyne without a sclerotized central plate ( Figs 5 View FIGURE 5 C–D, 6C).

Etymology. The species name is a matronym for Tharina Bird (Pretoria, South Africa), in recognition of her work on Solifugae and for her collections in remote areas of Namibia and Botswana, allowing the discovery of this new species.

Description. Male (Holotype, NCA 2020/541). Total length: 2.24. Carapace: length 1.25, width 1.06, height 0.58.

Colour ( Figs 4 View FIGURE 4 A–B). Carapace medium brown, darker along margin and with dark, inverted arrowhead mark in front of fovea; eye region black; chelicerae, labium and endites brown; sternum medium brown; legs: cx and tr yellow, Fe brown, remaining leg parts yellowish brown; palps yellowish brown; abdomen with dark grey dorsum with two faint brownish blotches in centre, followed by brownish transverse bars, venter medium brown.

Carapace ( Fig. 4A View FIGURE 4 ). Cephalic area with cover of silvery setae; thoracic area with setae cover less dense.

Eyes. ALE 0.11; AME 0.10; PLE 0.06; PME 0.06; ALE-AME 0.05; AME-AME 0.03; PME-PME 0.12; MOQ 0.30 wide in front, 0.33 wide at posterior end, 0.21 long. Clypeus 0.12 high.

Sternum ( Fig. 4B View FIGURE 4 ). 0.64 long, 0.70 wide, shield shaped, with straight anterior margin, lateral margins with intracoxal triangular sclerites.

Legs. With dense cover of flattened incised setae. Fe with one dorsal spine near base.

Leg measurements.

Abdomen ( Figs 4 View FIGURE 4 A–B). Oval, venter slightly sclerotized.

Palp ( Figs 5 View FIGURE 5 A–B, 6A–B): Cymbium flat, with small patch of chemosensitive setae, one distal spine and one prolateral modified seta; RTA thin triangle, with large base and down-curved, tapered, blunt tip; subtegulum large, visible over entire length of bulbus; MA massive, strongly curved, distal part widened, directed backward, with tip mesally concave; tegulum at base of E with short, blunt projection; E parallel-sided, slightly curved outward; distal tegular apophysis as long as E, hook-shaped at tip.

Female (Paratype, NCA 2020/542). Total length 3.39. Carapace: length 1.60, width 1.28, height 0.64.

Colour ( Figs 4 View FIGURE 4 C–D). Carapace brown, with darker radiating striae; eye region black; chelicerae brown, sternum medium brown with darker margin; legs: cx and tr yellow, Fe medium brown with paler proximal end, remainder yellowish brown; palp femora medium brown, remaining segments yellowish brown; abdomen dorsum dark grey with pair of roundish brown spots followed by pair of adjacent spots, 5 transverse bars and pale patch around anal tubercle; venter pale, light grey to cream anteriorly, gradually darkened towards dark grey sides; spinnerets pale.

Carapace ( Fig. 4C View FIGURE 4 ). Pear-shaped, with sparse cover of dark setae.

Eyes. ALE 0.10; AME 0.15; PLE 0.10; PME 0.08; ALE-AME 0.03; AME-AME 0.08; PME-PME 0.23; MOQ 0.38 wide in front, 0.39 wide at posterior end, 0.39 long. Clypeus 0.15 high.

Sternum ( Fig. 4D View FIGURE 4 ). 1.10 long and 0.94 wide, roughly shield-shaped, straight at anterior margin, with black setae at margins but without setae centrally.

Legs. Densely covered with flattened incised setae. Fe with one dorsal spine near base.

Leg measurements

Abdomen ( Figs 4 View FIGURE 4 C–D). Ovoid, with short uniform black setae throughout, only marginally longer at posterior end.

Epigyne ( Figs 5 View FIGURE 5 C–E, 6C). Posterior median lobe twice as wide as long, widest at lateral midpoint. Vulva: spermathecae twisted cylindrical provided internally with spiral of 3 turns. Anterior median duct of spermathecae converging slightly forward at anterior apex.
