ETYMOLOGY. Named after the Haud area, a region of thornbush and grasslands in the Horn of Africa characterized by red sands, see Fig. 136 View Figures 136–137 .

DIAGNOSIS. Total length of males 27–31 mm, of females 31–33.5 mm. Trichobothrium db on fixed finger of pedipalp situated between trichobothria et and est. Sexual dimorphism not pronounced; manus of pedipalp about the same width in both sexes. Pectine teeth number 16–19 in males, 14–16 in females. Chelicerae yellow, anterior manus reticulated. Pedipalps sparsely hirsute. Metasoma with only a few setae. Base color yellowish to orange brown. Dorsal surfaces of pedipalps and ventral surfaces of metasoma with numerous dark spots. Mesosoma yellowish to reddish brown, with black spots. Femur of pedipalp with 5 carinae that may be incomplete. Patella with 8 granulated carinae. Chela lacks carinae except dorsal carinae which are present or indicated, surfaces usually granulate. Movable fingers of pedipalps with 10–11 rows of denticles and 4 terminal and one basal terminal denticles. Sternite VII bears 4 well marked carinae, usually granulated. Metasoma I–IV with 10 carinae; metasoma V with 5 carinae. All carinae granulated, dorsal carinae bear larger posterior terminal granules. Metasoma narrow; metasomal segment I of adults usually longer than wide or as long as wide; metasomal segment II always longer than wide; metasomal segment IV length/width ratio 1.5–1.7 in both sexes. Telson vesicle bulbous, telson length/depth ratio 2.28 in female.

DESCRIPTION. Total length of adult males 27–31 mm, females 31–33.5 mm. Trichobothrium db on fixed finger of pedipalp is situated between trichobothria et and est. Pedipalp fingers proximally rather straight in both sexes. Female has more bulbous telson vesicle than male. Chelicerae yellow, anterior manus reticulated. For the position and distribution of trichobothria see Figs. 69–73, 75–76 View Figures 68–88 .

Coloration ( Figs. 19–24 View Figures 15–22 View Figures 23–43 ). Whole body yellowish or orange brown; carapace, tergites, metasoma, telson, dorsal surfaces of pedipalps and legs with black spots; tarsomeres of legs yellow without spots.

Carapace and mesosoma ( Figs. 46–53 View Figures 46–49 View Figures 50–59 ). Carapace carinate and unevenly covered by granules of varying size; much of the granulation is fine, but some granules are larger and distinctly rounded. Tergites I–VI bear three carinae and are granulated, with some intercarinal granules small and others larger and rounded. Tergite VII is pentacarinate. Pectinal tooth count is 16–19 (1x16, 1x17, 4x18, 4x19) in males and 14–16 (2x14, 2x16) in females. Pectinal marginal tips extend to the posterior end of sternite III in males and to the proximal ¾ of sternite III in females. Pectines have 3 marginal lamellae and 7–9 middle lamellae. Lamellae bear numerous dark long setae, each fulcrum with 3–5 setae. All sternites sparsely hirsute and finely granulated with smooth parts mainly in medial area. Sternite VII with four granulate carinae, other sternites have two furrows.

Metasoma and telson ( Figs. 60–67 View Figures 60–67 ). All metasomal segments only very sparsely hirsute. Metasoma I–IV with 10 carinae, metasoma V with 5 carinae. All carinae granulated, dorsal carinae bear larger posterior terminal granules. First metasomal segment of adults usually longer than wide or as long as wide, second metasomal segment always longer than wide. Telson vesicle bulbous and sparsely granulated. Telson length/depth ratio 2.28 in female.

Pedipalps ( Figs. 68–88 View Figures 68–88 ). Pedipalps sparsely hirsute and granulated. Femur with five granulate carinae, patella with eight granulate carinae and chela with dorsal carinae present or indicated, other carinae absent. Movable fingers of pedipalps bear 10–11 rows of denticles and 4 terminal and one basal terminal denticles.

Legs ( Figs. 54–57 View Figures 50–59 ). Tarsomeres have two rows of macrosetae on the ventral surface and numerous macrosetae on the other surfaces; bristle combs absent. Femur coarsely granulose with only several macrosetae, femur and patella with carinae well developed. Moderate tibial spurs present on legs III–IV and absent on other legs.

Hemispermatophore ( Figs. 144–146 View Figures 140–146 ). Flagelliform; flagellum folded into pars recta and pars reflecta. Pars recta shorter, with fin-like expansion of anterior margin; pars reflecta about twice as long as pars recta, narrow, hyaline. Trunk long, narrow, basally widened with attached pedicel. Capsule short, sperm hemiduct divided into 3 laminate lobes: posterior lobe longest, with rounded apex; median lobe shortest, tapered, apically acuminate, concave side connected to posterior lobe along proximal half of midline rib or median lobe carina; anterior lobe of intermediate length, distal portion narrower but not tapered, with blunt apex. Basal lobe short, strong, hook-like, located at base of median lobe. Morphology was similar in both left and right hemispermatophores examined from paratype 1198. Measurements of left hemispermatophore (mm): trunk L, 3.76; capsule L 0.33; flagellum pars recta L 0.90, pars reflecta L 2.04, total L 2.94.

Measurements. See Table 1.

AFFINITIES. The described features distinguish H. haudensis   sp. n. from all other species of the genus. It is the smallest species of the genus. Certain morphological features (characteristic spots and narrow metasoma) are shared with H. polystictus   , suggesting a close affinity with this species. These two species can be differentiated by: 1) total length 27–31 (males), 31–33.5 (females) mm in H. haudensis   sp. n., vs. total length 35–45 (males), 40–55 (females) mm in H. polystictus   ; 2) pectinal tooth counts of 16–19 in males, 14– 16 in females of H. haudensis   sp. n., vs. counts of 22–24 in males, 18–20 in females of H. polystictus   , with pectines being distinctly shorter in H. haudensis   sp. n.; 3) movable fingers of pedipalps with 10–11 rows of denticles in H. haudensis   sp. n., vs. 12–14 rows of denticles in H. polystictus   .

COMMENTS ON LOCALITIES AND LIFE STRATEGY. The type locality of Hottentotta haudensis   sp. n., (Somaliland, Shanshade Village, 08°39'35"N 45°55'49"E, 790 m a. s. l., 18SJ), in a red sandy semidesert ( Fig. 136 View Figures 136–137 and figs. 60–61 in KovařÍk & Lowe, 2019), is also the type locality of three other buthid scorpions, Gint banfasae KovařÍk & Lowe, 2019   (the numerically dominant scorpion species at this locality), Parabuthus kabateki KovařÍk et al., 2019   , and Parabuthus mazuchi KovařÍk et al., 2019   . All scorpions were recorded at night during UV collecting together with another rare buthid, Lanzatus somalilandus KovařÍk & Lowe, 2016   . We visited this locality on 29–31 August 2018 and recorded a maximum daytime temperature of 40 ºC, and a minimum nighttime temperature of 23 ºC. The recorded humidity was between 24% (minimum at day) and 65% (maximum at night).
