ETYMOLOGY. Named after Dr. Scott A. Stockwell, who has contributed to our knowledge of scorpions in many areas.

DIAGNOSIS. Total length 41–50 mm. For habitus see Figs. 112–113 View Figure 112 View Figure 113 . Trichobothrium db on the fixed finger of pedipalp situated between trichobothria et and est, near est. Male with fingers proximally twisted, manus and metasomal segments wider than female, Pectinal teeth number 24–25. Chelicerae yellow to green, without reticulation. Entire body only sparsely hirsute, especially metasomal segments. The hairs on patella of pedipalps are short. Color uniformly yellow to yellowish brown. Metasomal carinae may be black. Femur of pedipalp with 5 carinae. Dorsal surfaces of femur and internal surface of patella granulated. Patella with 2 or 4 carinae on internal surface, no other carinae. Chela lacks carinae. Movable fingers of pedipalps with 14 rows of granules and 5 terminal granules. Seventh metasomal segment with 4 well marked ventral granulated carinae. Dorsal surfaces of mesosoma and carapace densely granulated. First to third metasomal segments with 10 carinae; fourth segment with eight carinae and a short row of granules in the center of lateral part; fifth segment with 5 carinae. Metasoma granulated between carinae except dorsal surface, which is sparsely granulated, usually smooth at center and often bears 2 short, inconspicuous carinae. Telson also granulated. Dorsal carinae of metasomal segments bear larger terminal granules. First metasomal segment of adults wider than long, but second and third metasomal segment longer than wide in both sexes. Second to fourth metasomal segment width ratio is around 1.1. Length to width ratio of fourth metasomal segment around 1.4–1.5.

DESCRIPTION: Total length 41 (male allotype)–50 (female holotype) mm. The habitus is shown in Figs. 1 12–113 View Figures 1–4 View Figures 5–8 View Figures 9–12 View Figures 13–16 View Figures 17–20 View Figure 21 View Figure 22 View Figure 23 View Figure 24 View Figure 25 View Figure 26 View Figure 27 View Figure 28 View Figure 29 View Figure 30 View Figure 31 View Figure 32 View Figure 33 View Figure 34 View Figure 35 View Figure 36 View Figure 37 View Figure 38 View Figure 39 View Figure 40 View Figure 41 View Figure 42 View Figure 43 View Figure 44 View Figure 45 View Figure 46 View Figure 47 View Figure 48 View Figure 49 View Figure 50 View Figure 51 View Figure 52 View Figure 53 View Figure 54 View Figure 55 View Figures 56–59 View Figure 60 View Figure 61 View Figure 62 View Figure 63 View Figure 64 View Figure 65 View Figure 66 View Figure 67 View Figure 68 View Figure 69 View Figure 70 View Figure 71 View Figure 72 View Figure 73 View Figure 74 View Figure 75 View Figure 76 View Figure 77 View Figure 78 View Figure 79 View Figure 80 View Figure 81 View Figure 82 View Figure 83 View Figure 84 View Figure 85 View Figure 86 View Figure 87 View Figure 88 View Figure 89 View Figure 90 View Figure 91 View Figure 92 View Figure 93 View Figure 94 View Figure 95 View Figure 96 View Figure 97 View Figure 98 View Figure 99 View Figure 100 View Figure 101 View Figure 102 View Figure 103 View Figure 104 View Figure 105 View Figure 106 View Figure 107 View Figure 108 View Figure 109 View Figure 110 View Figure 111 View Figure 112 View Figure 113 . Measurements of the carapace, telson, segments of the metasoma and of the pedipalps, and numbers of pectinal teeth in the holotype and allotype are given in Table 1. Trichobothrium db on the fixed finger of pedipalp is situated between trichobothria et and est ( Fig. 1 View Figures 1–4 ), nearly on the same level as trichobothrium est. Pectinal teeth number 24–25 in male and 24– 24 in female. Chelicerae yellow to green, without reticulation, only tips of teeth on fingers of chelicerae are black. The male with fingers proximally twisted, manus and metasomal segments wider than female, long of the metasomal segments is the same in both sexes.

COLORATION: Color uniformly yellow to yellowish brown. Mesosomal segments usually with orange posterior band. Metasomal carinae may be black as well.

MESOSOMA AND CARAPACE: The mesosoma has three carinae on the dorsal surface and two carinae on the ventral surface with the exception of the seventh segment, whose ventral surface bears four well marked carinae. The dorsal surface is densely granulated (granules take up more space than the gaps between them), whereas the ventral surface is smooth.

PEDIPALPS: The pedipalps are hirsute, but not densely. The hairs are short. The femur of pedipalps has five carinae and the dorsal surface is covered by granules. Patella with 2 or 4 carinae and granules on internal surface, no other carinae. Chela lacks carinae. Movable fingers of pedipalps with 14 rows of granules and 5 terminal granules.

METASOMA AND TELSON: The first metasomal segment of both sexes is always wider than long, but the second and third metasomal segments longer than wide in both sexes. The first to third segments bear 10 carinae, the fourth segment bears eight carinae and a short row of granules in the center of lateral part, and the fifth segment bears only five carinae. Metasoma granulated between carinae except dorsal surface, which is sparsely granulated, usually smooth at center and often bears 2 short, inconspicuous carinae. Telson also granulated. Dorsal carinae of metasomal segments bear larger terminal granules. Second to fourth metasomal segment width ratio is around 1.1. Length to width ratio of fourth metasomal segment around 1.4–1.5 (see Table 1).

COMMENTS. Since the examined male is mounted dry, I therefore designate a female preserved in alcohol as the holotype.

AFFINITIES. The described features distinguish H. stockwelli sp. n. from all other species of the genus. They are recounted in the key below. H. stockwelli sp. n. is closest to H. finneganae sp. n. from Pakistan. Apart from the number of rows of granules on the movable fingers (see key), which may be found to some degree to be variable in newly discovered specimens, the two species differ in the granulation of mesosomal segments, with the granules markedly larger and much more dense in H. stockwelli (granules take up more space than the gaps between them). Also the hair cover of the pedipalps is different, denser and much shorter in H. stockwelli sp. n. These two species are similar to the widely distributed H. rugiscutis , with which they share size and number of teeth in the pecten. However, they have markedly narrower metasoma, in which the second segment of both sexes is longer than wide (see Table 1 and Figs. 88 View Figure 88 and 112 View Figure 112 ).

As to the pubescence of pedipalps, it should be added that three Indian species ( H. rugiscutis , H. stockwelli sp. n. and H. tamulus ) have the patella densely covered by short hairs with scattered sparse long hairs. All other species of Hottentotta have only long hairs on the patella, either dense or sparse.
