Chelal trichobothrium Eb 3 located in middle of manus at same level as Dt . Fingers of pedipalps slightly straight in both sexes; male has small internal apophysis on movable finger. Chela length to width ratio 3.6–3.7 in male and 3.2 in female. Pedipalp movable finger with 25–30 IAD, ca. 55 MD which create 10 straight rows in a line and there are also 4–5 ID and 11 OD present. Tarsomere II of legs with row of 6–7 stout median ventral spinules and two pairs of flanking setae. Metasoma I–II with 10 carinae, and metasoma III–IV with 8 carinae. Telson rather elongate, sparsely granulate, more so in male, length to depth ratio 2.8 in male and 3 in female; annular ring present. DESCRIPTION ( ♂ ♀ ). Total length 23–28 mm . Habitus as shown in Figs. 754–757 . For position and distribution of trichobothria on pedipalps, see Figs. 766a–771a . Sexual dimorphism: adult males have larger pectines than females; pedipalp chela and patella are more narrow in male; fingers of pedipalps are straight in both sexes ( Figs. 767 and 774 ); male has the small apophysis on the internal surface of the movable finger reduced in size ( Fig. 791 ). Coloration ( Figs. 754–757 , 793–797 ). Base color uniformly reddish black to black. Legs and telson are yellow to reddish brown, sternites lighter, yellowish to reddish brown. Chelicerae yellowish brown and reticulate, fingers reddish brown. Figures 754–757 : Scorpiops thailandus sp . n . Figures 754–755 . Male holotype in dorsal (754) and ventral (755) views.

Pedipalp chela internal views. Figures 790–792 . Movable finger dentition under UV light. Carapace and mesosoma ( Figs. 754–757 , 780–783 ). Entire carapace covered with minute granules; carinae absent. Anterior margin of carapace with a deep median notch. Carapace with two, or two normal and one reduced pairs of lateral eyes. Mesosoma granulated, with one median carina developed. Tergite VII is pentacarinate. Sternites smooth or finely granulated with two parallel furrows except sternite VII which is strongly granulated with two carinae incomplete. Pectine teeth number 6–7 in males and 5–6 in females. Pectines with 2 marginal and 1–3 middle lamellae; fulcra absent. Metasoma and telson ( Figs. 758–765 ). 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 carinae of metasoma II and V indicated by isolated granules that may coalesce into carinae. Dorsolateral carinae of segments II–IV terminate posteriorly in a pronounced tooth. Telson elongate and granulate, more so in males, with annular ring developed in both sexes. Pedipalps ( Figs. 766–778 ). Pedipalps very sparsely hirsute. Patella with 17 (5 eb , 2 esb , 2 em , 4 est , 4 et ) external and 8–9 ventral trichobothria. Chela with 4 V series trichobothria located on the ventral surface. Femur and patella are finely granulated. Femur with 3–4 granulose carinae, and patella with 5 carinae, with dorsal patellar spurs reduced and ventral patellar spurs pronounced. Manus dorsally with fine reticulated, rounded granules, which in the central area form an irregular dorsal secondary carina. External surface of chela covered by minute granules, with an almost complete external secondary carina with larger sparse granules. Movable fingers with ca. 25–30 IAD, ca. 55 MD which create 10 straight rows in a line and there are also 4–5 ID and 8 OD present. Legs ( Figs. 784–787 ).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 with row of 6–7 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 .
