M. Stockmann , FKCP . ETYMOLOGY. The species epithet is a patronym honoring Renate Scheibe from University Osnadrück who assisted one of authors (MS) with a venom extraction project. DIAGNOSIS ( ♂ ). Total length 70 mm . Base color uniformly reddish black to black. Telson and tarsomere II of legs reddish brown. Pectine teeth number 12 in male; fulcra reduced to absent; 3 marginal and 5 middle lamellae. Patella of pedipalp with 58 external and 24 ventral trichobothria. Chela of pedipalp with 14 V series trichobothria, of which the 3 most proximal are located on external surface near Eb 1 . Chelal trichobothrium Eb 3 located in distal half of manus between trichobothria Dt and Est . Fingers of pedipalps undulate in male. Chela length to width ratio 4. Pedipalp movable finger with 68 IAD, which have the same size as MD (> 100 in number) and create a second row; there are also 5 ID and 15 OD present. Tarsomere II of leg III with four stout median ventral spinules and two pairs of flanking setae. Metasoma I with 10 carinae and metasoma II–IV with 8 carinae. Telson elongate and granulate, length to depth ratio 3.56 in male; annular ring developed. DESCRIPTION ( ♂ holotype ). Total length 70 mm . Female unknown. Habitus as shown in Figs. 634–635 . For position and distribution of trichobothria on pedipalps, see Figs. 639– 641 . Fingers of pedipalps undulate in male ( Fig. 640 ). Coloration ( Figs. 634–635 , 652 ). Base color uniformly reddish black to black. Telson, legs, and sternites are reddish brown. Chelicerae reddish brown and reticulate, fingers black. Carapace and mesosoma ( Figs. 634–635 , 647–648 ). 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 to very finely granulated with two parallel furrows except sternite VII which has four granulate carinae. Pectine teeth number 12 in male holotype . Pectines with 3 marginal and 4 middle lamellae, fulcra reduced or absent. Metasoma and telson ( Figs. 636–638 , 651 ). 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 which is on metasoma IV wide with three peaks. Telson elongate and granulate with annular ring developed. Pedipalps ( Figs. 639–642 ). Pedipalps very sparsely hirsute. Patella with 58 external trichobothria (which cannot be assigned to standard eb , esb , em , est , and et territories) and 24 ventral trichobothria. Chela with 14 V series trichobothria, of which the 3 most proximal are located on external surface near Eb 1 . Femur and patella granulated. Femur with 5 granulose carinae, and patella with 5 carinae, with dorsal and ventral patellar spurs pronounced. Manus dorsally with fine, rounded granules, which in the central area form an irregular dorsal secondary carina. External surface of chela densely covered by minute granules, with an irregular external secondary carina. Movable fingers bear 68 IAD, which have the same size as MD (more than 100 in number) and create a second row; there are also 5 ID and 15 OD present. Legs ( Figs. 643–646 ). 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–II, IV with 5 stout median ventral spinules and two pairs of flanking setae, leg III with 4 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 7 .
