TYPE MATERIAL EXAMINED. Somaliland , Sahil region, Laas Dhuure Village, 10.176807°N 45.983479°E, ca 540 m a.s.l. (LocalitY No. 21SK, Fig. 32 ), 11-12 October 2021, 1♂ (holotYpe, DNA 1999), leg. F. KovařÍk.

ETYMOLOGY. The specific epithet is a patronYm honoring Hassan Sh Abdirahman Elmi (Somaliland, Amoud UniversitY), who helped with Somaliland expeditions and collecting scorpions.

DIAGNOSIS. See generic diagnosis.

DESCRIPTION (♂). The male holotYpe is 28 mm long. The habitus is shown in Figs. 1–2 . For position and distribution of trichobothria of pedipalp see Figs. 15–19 , and 21–22.

Coloration ( Figs. 2–3 ). The base color is uniformlY Yellow to Yellowish orange, with two sYmmetrical dark spots in anterior part of carapace; two sYmmetrical dark stripes on tergites I–VI and metasoma I–IV dorsal. Tergite VII with three dark stripes. Other dark reduced spots and stripes are on metasoma dorsal and metasoma IV–V also on lateral and ventral surfaces and on femur of legs posteriorlY.

Carapace ( Figs. 11 , 13 ). Trapezoidal, anterior margin almost straight, with 6 marginal macrosetae; surface with dense, coarse granulation, weaker laterallY; carinae absent; median ocular tubercle granulate, median eYes large, well separated; 5 lateral eYes (3 larger, 2 reduced).

Chelicera ( Figs. 30–31 ). Fingers complY with the basic pattern of buthid dentition (Vachon, 1963); fixed finger with large distal denticle, one subdistal denticle and two basal denticles fused into bicusp, two denticles on ventral surface; dorsal margin of movable finger with 5 denticles: one large distal denticle, medium-sized subdistal denticle, large medial denticle, and two small basal denticles; ventral margin with 3 denticles: one large distal denticle, and two smaller denticles in medial and basal positions.

Mesosoma ( Figs. 11–14 ). Tergites I–VI tricarinate with a median carina, and an anteriorlY diverging pair of lateral carinae; carinae coarselY granular, the lateral pair on tergites I–II rather indistinct; all carinae short with onlY ca. 2–5 granules, confined to posterior third of tergite; entire tergites sparselY covered with coarse granulation; pretergites smooth; tergite VII pentacarinate, median carina indicated, lateral carinae well developed, coarselY granular; sternites with slit-like spiracles; with smooth surfaces locallY finelY granulated, on sternite III and laterallY on sternite VII; sternite III–VII without carinae; sternal chaetotaxy: sternite III–VI posterior margins bearing 3–5 macrosetae, III without macrosetae on medial surface, IV–VII with 2–4 macrosetae; pectines with margins extending to quarter of sternite V, with 3 marginal lamellae, 12 middle lamellae; lamellae and fulcra bear numerous short, fine, dark macrosetae; pectine basal piece and genital opercula smooth with fine macrosetae; pectinal tooth counts 24–25 in male. Sternum tYpe 1, relativelY small, and triangular to subpentagonal in shape; posterior depression verY large and deep.

Metasoma and telson ( Figs. 4–10 ). Metasoma I–IV with 10 granulated carinae, median lateral carinae on segments I–II complete, median lateral carinae on segments I–IV incomplete, indicated bY ca. 7–11 granules on posterior part; ventromedian and ventrolateral carinae stronger on segments II–III, with conspicuouslY enlarged, dentate granules increasing in size posteriorlY; metasoma V with 3 granulated ventral carinae, dorsolateral carinae granulated on IV and reduced to absent on V, ventrolateral carinae strong, irregularlY crenulated on V with several enlarged, lobate granules that become larger posteriorlY; intercarinal surfaces predominantlY smooth and partlY irregularlY granulated; lateral anal arch divided into 4 lobes; ventral anal arch armed with a regular series of coarse granules; telson with distinctlY elongated smooth vesicle; aculeus robust, equal to or shorter than vesicle in length, moderatelY curved; subaculear tubercle absent; chaetotaxy: metasomal segments and telson sparselY setose; long macrosetae dispersed irregularlY on lateral and ventral surface.

Pedipalps ( Figs. 15–25 ). Segments slender, with patella slightlY narrower than chelae; femur with 3 strong, granulated carinae: dorsoexternal, dorsointernal, and ventrointernal; ventromedial carina indicated bY several strong granules; dorsal, lateral and ventral surfaces smooth except for a few small solitarY granules, internal surface granulated; patella with two granulated and 5 smooth, obsolete carinae; setation sparse, with large solitarY macrosetae; chela smooth, carinae obsolete, rather denselY covered bY large macrosetae; dentate margins of fingers with 7 (movable finger) or 8 (fixed finger) rows of granules, 6 of them flanked bY a single external and internal accessorY granule, 7 th row with a single external granule, 8 th row of fixed finger without accessorY granule; distal ends of movable finger with 5 subterminal granules; trichobothrial pattern neobothriotaxic tYpe A-β (femur petite d 2 absent), fixed finger with db situated near base of finger and distal to est, dt at anterior part of finger distal to et (et is between dt and est).

Legs ( Figs. 26–29 ). Legs with robust patellae, tibiae and tarsi; femora with a few solitarY macrosetae; tibiae I–III with 5–7 long macrosetae in dorsal (retrosuperior) series, rather not forming a tibial ‘bristle comb’; basitarsi I–III compressed, with two irregular series of shorter ventral (proinferior and retroinferior) macrosetae, and a single linear series of 6–8 longer dorsal macrosetae (forming a basitarsal ‘bristle comb’); leg IV without basitarsal compression, longer than legs I–III; tibial spur on legs III–IV moderate; prolateral and retrolateral pedal spurs well-developed.

Measurements. See Table 1.
