ETYMOLOGY. Named after the country of occurence.

DIAGNOSIS. Total length 42–55 mm. Base color yellow dark pattern reduced; telson orange; chelicerae pale yellow without reticulation. Pedipalp movable fingers bear 10–11 rows of granules, with 11 outer and inner denticles and fixed finger with 9 outer and 10 inner denticles. Chela of pedipalp narrower in male, its length to width ratio 3.6–3.9 in females and 4.2–4.4 in males. Telson bulbous, with aculeus shorter than vesicle. Pectinal teeth number 23–26 in females and 30–35 in males.

DESCRIPTION. The adults are 42 mm (male) – 55 mm (female) long. The habitus is shown in Figs. 102–105 View Figures 102–105 , 193 View Figures 191–194 . For position and distribution of trichobothria of pedipalps see Figs. 114– 118 View Figures 114–131 , and 120. Sexual dimorphism minor: adult males with pedipalp chela broader. Female with a wide basal middle lamella ( Fig. 134 View Figures 132–139 ).

Coloration ( Figs. 102–105 View Figures 102–105 , 193 View Figures 191–194 ). The base color is uniformly yellow with dark pattern reduced in juveniles and often absent in adults, tergites yellow. The pedipalps and legs are yellow without dark carina in adults. Telson is orange.

Carapace and mesosoma ( Figs. 102–105 View Figures 102–105 , 132–135 View Figures 132–139 ). The entire carapace is covered with granules small along much of the middline and large anteriorly, posteriorly and laterally. The carinae are typical for genus Buthus , strongly developed and composed of large, round granules. The anterior margin of the carapace is straight, and bears 10–12 long, symmetrically placed macrosetae. The tergites are granulated in posterior parts and bear very strong median carinae. A pair of denticulate lateral carinae is strong on tergites II–VI. Tergite VII is pentacarinate, with all carinae strong and granulated. The pectinal tooth count is 23–26 (1x23, 6x24, 6x25, 1x26) in the females and 30–35 (2x30, 4x31, 5x33, 3x34, 2x35) in the males.

The pectinal marginal tips extend to the end of the fourth sternite or to the quoter of the fifth sternite in males and to the end of the third sternite in females. The pectines have three marginal lamellae and seven or eight middle lamellae. The lamellae bear numerous dark setae, each fulcrum with three to six dark setae. All sternites are smooth or finely granulated. The seventh sternite bears four strongly developed ventral crenulate carinae.

Metasoma and telson ( Figs. 106–113 View Figures 106–113 ). The first metasomal segment bears 10 carinae, the second throught fourth segments bear eight to 10 carinae (the lateral surface of the second and third segments bears a row of granules that exceeds three-quarters of the second and one-half of the third segment length). The fourth segment bear eight carinae and the fifth segment bears five carinae. The ventrolateral carinae of the fifth segment terminate in two lobes. The ventral keels on the second and third segments posteriorly bear two to four large granules. The surface between the carinae is smooth. All segments are sparsely setose. The telson is bulbous, with aculeus shorter than the vesicle. The surface of the telson is unevenly granulated and bears an incomplete lateral carina.

Pedipalps ( Figs. 114–131 View Figures 114–131 ). The pedipalps are smooth or finely granulated. The femur bears four to five carinae; the ventroexternal carina is incomplete, the other carinae are coarsely granular. The patella bears seven coarsely granular carinae. The chela bears five carinae, which may be weak and incomplete. The movable and fixed fingers bear 10–11 rows of granules, with 11 outer and inner denticles and fixed finger with 9 outer and 10 inner denticles.

Legs ( Figs. 136–139 View Figures 132–139 ). Pairs III and IV bear long tibial spurs. Retrolateral and prolateral pedal spurs are present on all legs. The tarsomeres bear two rows of macrosetae on the ventral surface and numerous macrosetae on the other surfaces. Bristlecombs are present on the first to third legs. The femur bears four carinae and the patella bears four to six carinae. The femur and patella bear only solitary macrosetae.

AFFINITIES. The described features distinguish B. somalilandus sp. n. from all other species of the genus. They are recounted in the key below. B. somalilandus sp. n. is similar to B. zeylensis . It is possible to mainly differentiate these two species mainly according to pedipalp movable finger dentition (see key below).
