ETYMOLOGY. The specific epithet honors Deshabhushan Bastawade ( India) for his friendship and contribution to understanding Indian scorpions.

DIAGNOSIS (♀). Total length 58 mm. Base color uniformly reddish black to black, telson and legs yellow. Pectine teeth 10–11 in female; fulcra absent; 3 marginal and 4–5 middle lamellae. Patella of pedipalp with 57–75 external and 22– 26 ventral trichobothria. Chela of pedipalp with 4 V series trichobothria located on ventral surface. Chelal trichobothrium Eb 3 located in distal half of manus between trichobothria Dt and Est. Fingers of pedipalps undulate in female. Chela length to width ratio 3.8–4.4 in females. Pedipalp movable finger with ca. 50 IAD, which have the same size as MD (ca. 85 in number) and create a second row; there are also 5 ID and 15 OD present. Tarsomere II of leg III with 4–6 stout median ventral spinules in a single row, and two pairs of flanking setae. Metasoma I with 10 carinae, metasoma II–IV with 8 carinae. Telson elongate and very finely granulate, length to depth ratio 3.7 in female; annular ring developed.

DESCRIPTION (♀). Total length 58–59 mm. Male unknown. Habitus as shown in Figs. 299–300 View Figures 299–304 . For position and distribution of trichobothria on pedipalps, see Figs. 309a–314a View Figures 305–317 . Fingers of pedipalps undulate in female ( Fig. 310 View Figures 305–317 ).

Coloration ( Figs. 299–300 View Figures 299–304 , 328 View Figures 327–328 ). Base color uniformly reddish black. Telson, legs, and sternites are yellow. Chelicerae yellowish brown and reticulate, fingers black.

Carapace and mesosoma ( Figs. 299–300 View Figures 299–304 , 318–321 View Figures 318–326 ). Entire carapace covered with large granules; carinae absent. Anterior margin of carapace with a deep median notch. Carapace with 3 pairs of lateral eyes of which two are normal and one is reduced. Mesosoma granulated, with one median carina. Tergite VII is pentacarinate. Sternites smooth with two parallel furrows except sternite VII which has four granulate carinae. Pectine teeth number 10–11 in females. Pectines with 3 marginal and 4–5 middle lamellae; fulcra absent.

Metasoma and telson ( Figs. 301–304 View Figures 299–304 ). Metasoma sparsely hirsute and granulated, with sparse, relatively large granules. Metasomal segment I with 10 carinae, II–IV with 8 carinae, and V with 5 carinae. Median lateral carina of metasoma I incomplete, that of metasoma II represented by several posterior granules. Dorsolateral carinae of the second to fourth segments terminate posteriorly in a pronounced tooth. Telson elongate and very finely granulate with annular ring developed.

Pedipalps ( Figs. 309–317 View Figures 305–317 ). Pedipalps very sparsely hirsute. Patella with 57–75 external and 22–26 ventral trichobothria. Chela with 4 V series trichobothria located on the ventral surface. Femur and patella granulated. Femur with 5–6 granulose carinae, and patella with 5 carinae with dorsal and ventral patellar spurs pronounced. Manus dorsally with fine, rounded reticulated granules, which in the central area form an irregular dorsal secondary carina. External surface of chela densely covered by minute granules, with an almost regular external secondary carina. Movable fingers with ca. 50 IAD, which have the same size as MD (ca. 85 in number) and create a second row; there are also 5 ID and 15 OD present.

Legs ( Figs. 322–325 View Figures 318–326 ). Tibia and tarsomeres of legs with several setae not arranged into bristle combs on dorsal surfaces, but with rows of spinules on dorsolateral surfaces and on legs I – II also on ventrolateral surface. Tarsomere II of legs I–IV with row of 4–6 stout median ventral spinules, and two pairs of flanking setae. Femur with 3–4 and patella 4–5 carinae; both femur and patella granulated.

Measurements. See Table 2.

AFFINITIES. The most similar species is S. grandjeani in which the pedipalp chela has 4 V trichobothria located on the ventral surface, and the pedipalp patella has 54–59 external and 22–23 ventral trichobothria. This unique combination was the key character for the genus Dasyscorpiops which is herein synonymized with the genus Scorpiops . These two species could be easily differentiated by the shape of the pedipalp segments which are in the female (male is unknown in both these species) more narrow in S. grandjeani than in S. bastawadei sp. n. ( Figs. 327–328 View Figures 327–328 , Table 2, and fig. 12 in Lourenço, 1998: 251). In the females, pedipalp chela length to width ratio is 5.1–5.2 in S. grandjeani , vs. 3.8–4.4 in S. bastawadei sp. n.; pedipalp patella length to width ratio is 2.8–2.9 in S. grandjeani , vs. 2.4–2.6 in S. bastawadei sp. n.; and pedipalp femur length to width ratio is 3.6–3.7 in S. grandjeani , vs. 3.1–3.4 in S. bastawadei sp. n.
