ETYMOLOGY. It is a pleasure to name this species after Stefan Friedrich (Munich, Germany).

DIAGNOSIS. Total length 61–80 mm. Base color uniformly reddish brown to black, legs and telson yellow, pedipalp chela orange to reddish brown. Carapace smooth in middle, covered by granules along margins. External trichobothria on patella number 14–15 (5 eb, 3 esb, 2 em, 1–2 est, 3 et); ventral trichobothria on patella number 22–28; internal trichobothria on chela number 6–7, ventral trichobothria on chela number 9–12. Pedipalp chela hirsute rather sparsely. Pedipalp chela dorsally smooth to bumpy, without pointed granules, lobe smooth. Chela internal smooth sparsely granulated mainly in anterior part, with two longitudinal carinae indicated by 4–6 granules. Chela of male length/ width ratio is 1.62–1.69. Pectinal teeth number 15–16 in males. Sternite VII densely granulated. Metasomal segments I– V ventrally densely granulated; metasomal segments I– IV with ventral carinae absent. Spiniform formula of tarsomere II = 3/4: 3/4: 3/5: 3/5. Tarsomere II with 2 spines on inclined anteroventral surface. Length to width ratio of male metasomal segment V is 2.14–2.17.

DESCRIPTION. The adult males are 61–80 mm long, female unknown. The habitus is shown in Figs. 9–10. For position and distribution of the trichobothria of pedipalps see Figs. 14–20. External trichobothria on patella number 14–15 (5 eb, 3 esb, 2 em, 1–2 est, 3 et); ventral trichobothria on patella number 22–28; internal trichobothria on chela number 6–7, ventral trichobothria on chela number 9–12.

Coloration ( Figs. 9–10). The base color is uniformly reddish brown to black, legs and telson are yellow, pedipalp chela is orange to reddish brown, chelicerae are yellow to orange, and carapace is reddish brown to black, lighter in the anterior part.

Carapace and mesosoma ( Figs. 9–10). The entire carapace is smooth in the middle, covered by granules along margins. The anterior margin of the carapace is symmetrically concave, medially strongly convex, and it bears several macrosetae. The tergites are smooth and can be very finely granulated, mainly tergite VI; tergite VII is strongly granulated. The pectinal tooth count is 15–16 in males, female unknown. The pectine marginal tips extend to quarter of the fourth sternite in the male. The sternites are smooth, without carinae, but with two longitudinal furrows; sternite VII is densely granulated.

Metasoma and telson ( Figs. 11–13). The metasomal segments I–IV bear a total of 6 sparsely granulated carinae. The ventral carinae are absent. The fifth segment has five variously developed and granulated carinae. The dorsal and lateral surfaces of the segments are smooth with several solitary granules. The metasomal segments I–V ventrally densely granulated with the same intensity on all segments. The entire metasoma and telson are sparsely hirsute. The telson is smooth, elongate, with the aculeus approximately as long as vesicle or shorter.

Pedipalps ( Figs. 14–21). The pedipalps are hirsute. The femur is granulated dorsally and bears four carinae composed of several strong granules. The patella is smooth, finely granulated on internal surface only, there are two externo lateral smooth carinae and one internal carina is indicated by 5–7 big granules. Pedipalp chela is dorsally smooth to bumpy, without carinae and pointed granules, lobe smooth. Several well defined granules are present on external suface. The chela internal is smooth, sparsely granulated mainly in anterior part, with two short characteristic smooth longitudinal carinae indicated by 4–6 granules. The movable and fixed fingers of the pedipalp with distinct granules in a row divided into 5–7 rows by big concave granules.

Legs. All legs are without distinct carinae and smooth. The tarsomeres are hirsute with setae and macrosetae more densely on legs I–II. For spiniform formula of tarsomeres of legs see paragraph under Pandinops section.

Measurements. See Table 1.

AFFINITIES. The described features distinguish P. friedrichi sp. n. from all other species of the genus. They are recounted in the key below. Kovařík (2009: 53, 118, figs. 323–324) misidentified the specimen from MZUF collection as P. peeli , which has also granulated metasomal segments I–II ventrally but differently than P. friedrichi sp. n. (see the key below and Figs. 64 versus 66). These two species occur in different areas of distribution. P. peeli is known from the northern Somaliland, and P. friedrichi sp. n. from south Somalia ( Fig.

69) where it represents the southern limits of the genus Pandinops distribution.
