EMENDED DIAGNOSIS (♂ ♀). Total length 95–110 mm. Color uniformly reddish brown to black, legs yellow. Chelicerae brown, reticulate, with black fingers and anterior margins. Carapace lacking carinae and finely (♀) or coarsely (♂) granulated. External trichobothria on patella number 15 (5 eb, 3–4 esb, 2 em, 1–2 est, 3 et); ventral trichobothria on patella number 41–46; internal trichobothria on chela number 2, ventral trichobothria on chela number 10–11. Pedipalp chela densely hirsute. Pedipalp chela dorsally with evenly-sized conspicuous granules. Dorsoexternal surface of chela with four carinae indicated by rows of granules mainly in females. Chela internally with two longitudinal carinae covered by granules. Chela of male length/ width ratio 1.89. Pectinal teeth number 19–20 in male, 19–23 in females. Dorsal carinae on first through fourth metasomal segments denticulate, usually with smooth (♀) or sharp (♂) denticles. Spiniform formula of tarsomere II = 6-7/5: 6-7/5: 7/5: 7/5. Tarsomere II with 3 spines on inclined anteroventral surface. Length to width ratio of metasoma V of male 2.43.

TAXONOMIC REMARKS. P. somalilandus was based solely on the holotype and paratype females. The male described herein is the first known male belonging to this species. Sexual dimorphism is one of the important characters in the taxonomy of Pandininae .

KovařÍk et al. (2017c) defined three key morphological characters for differentiation of genera Pandiborellius Rossi, 2015 and Pandinurus Fet, 1997 : (1) patella external surface with 3 or 4 trichobothria in est series in Pandinurus ( Fig. 58 View Figures 54–66 and figs. 194–203 in KovařÍk et al., 2017c: 41) vs. 1 or 2 trichobothria in Pandiborellius ( Fig. 16 View Figures 12–24 and figs. 189–193 in KovařÍk et al., 2017c: 41); (2) dentate margin of pedipalp chela fixed and movable fingers with distinct granules in two parallel rows present in anterior half of fingers in Pandinurus ( Figs. 23–24 View Figures 12–24 ) vs. dentate margin of pedipalp chela fixed and movable fingers with distinct granules in a row in Pandiborellius ( Figs. 21–22 View Figures 12–24 ); (3) male with more strongly pronounced lobate tooth on pedipalp movable finger than female in Pandinurus (figs. 144–167 in KovařÍk et al., 2017c: 37) vs. male with usually slightly more pronounced lobate tooth on pedipalp movable finger than female in Pandiborellius (figs. 126–143 in KovařÍk et al., 2017c: 37).

The herein described male of Pandiborelius somalilandus complies with the first two of these key characters for Pandiborellius . However,itpossessesamorestronglypronounced tooth on the pedipalp movable finger than female ( Figs. 62–64 View Figures 54–66 ), a character previously used to diagnose Pandinurus . This condition can assist in differentiating P. somalilandus from all other known Pandiborellius species, but it demonstrates that this character cannot be used at the generic level.
