(Figs. 34–47)  
TYPE LOCALITY AND TYPE REPOSITORY. Indonesia, Borneo Island; RMNH.  
TYPE MATERIAL. Indonesia, Borneo Island, Exped. Dr. Nieuwenhuis, 1894, 2♂ 1♀ 3juvs. (holotype, allotype and paratypes), RMNH Nos. 279 and 280; Malaysia, Borneo Island, Sabah, Sepilok, 1♂ (paratype), III.2012, leg. M. Černička, FKCP; Malaysia, Borneo Island, Sabah, Kinabatangan, 1♂ 1♀ 12 juveniles (paratypes, still alive), III.2012, leg. J. Severa, FKCP.  
ETYMOLOGY. Named after my colleague and friend Michael Soleglad, who has contributed to our knowledge of scorpions in many ways.  
DIAGNOSIS. Total length 42–45 mm. Two pairs of lateral eyes and one pair of median eyes. Movable finger of pedipalp with 7 or 8 cutting edges composed of granules. Fingers straight in both sexes. Manus of pedipalp in male robust. Chela of pedipalp with 7 or 8 carinae, patella with 5 carinae, femur with 4 carinae. Pectinal teeth number 4–5. Chela of pedipalp wide and ampullar, identical in both sexes or wider in male than in female. Entire carapace granulated. Even larger granules form two symmetrical, longitudinal carinae, which may reach posterior margin of carapace. Mesosomal tergites granulated, but without carinae. Sternites smooth, without carinae. First metasomal segments lack ventral carinae; ventral side of first metasomal segment usually smooth, but may bear several solitary granules. First through fourth metasomal segments with 6–8 carinae. All metasomal segments dorsally with a pair of rows of granules, which may form incomplete carinae. Fifth metasomal segment bears 7 carinae and is densely granulated.  
 DESCRIPTION. Total length 42–45 mm. Two pairs of lateral eyes and one pair of median eyes. The male has relatively larger pectens. Pectinal teeth number four (female) or five (male). For the position and distribution of trichobothria see Figs. 38–45. Trichobothrium d2 of the pedipalp patella is located on the edge between dorsal and internal surfaces. Trichobothrium d3 is located on the internal surface. (Fig. 41). The chelicerae are granulated.   
COLORATION. The color is dark brown to black.  
MESOSOMA AND CARAPACE. The entire carapace is covered by large granules, the larger of which form two longitudinal, symmetrical carinae. The anterior margin of carapace is straight. The mesosomal tergites are granulated, but without carinae. The sternites are smooth, without carinae and without glossy zones in the middle of the posterior margin.  
METASOMA AND TELSON. The first through fourth metasomal segments bear six to eight carinae (two ventral carinae and main lateral carinae may be poorly developed or absent); the fifth segment bears seven carinae of which one ventral carina posteriorly branches to form the letter “Y“. All carinae are composed of posteriorly inclined, denticulate granules. The spaces between carinae are irregularly granulated on lateral and ventral surfaces; the dorsal surface is smooth but bears pair rows of granules, which may form incomplete carinae. All segments are sparsely hirsute. The telson is elongate, smooth and sparsely hirsute.  
PEDIPALPS. The movable finger has seven or eight cutting edges composed of granules. The chela has seven or eight granulated carinae. The patella has five carinae and the femur has four carinae. All carinae consist of widely spaced, rounded granules. The spaces between carinae are covered by unevenly spaced small granules, which on the chela form a reticulate pattern.  
LEGS. The legs are hirsute, without bristlecombs and carinae.  
 MEASUREMENTS IN MM. Total length of male holotype 45; carapace length 6.4, width 6.6; metasoma and telson length 26.9; first metasomal segment length 2.7, width 3.7; second metasomal segment length 3.3, width 3.3; third metasomal segment length 3.4, width 3.3; fourth metasomal segment length 3.6, width 3; fifth metasomal segment length 6.7, width 2.9; telson length 7.2; pedipalp femur length 5.2, width 2.3; pedipalp patella length 5.6, width 2.7; chela length 12.2; manus width 6.1; movable finger length 6.3.   
 Total length of female allotype 42; carapace length 5.2, width 6.3; metasoma and telson length 23.5; first metasomal segment length 2.3, width 2.6; second metasomal segment length 2.4, width 2.5; third metasomal segment length 2.4, width 2.4; fourth metasomal segment length 3.5, width 2.8; fifth metasomal segment length 6.2, width 2.7; telson length 6.7; pedipalp femur length 4.5, width 1.9; pedipalp patella length 4.8, width 2.2; chela length 9.3; manus width 4; movable finger length 4.6.   
 AFFINITIES. The described features distinguish C. solegladi sp. n. from all other species of the genus. They are recounted in the key. The female of C. solegladi sp. n. is very similar to C. laevimanus, but the males of these two species are quite different. Whereas the male of C. laevimanus has longer and narower chela of pedipalps, the male of C. solegladi sp. n. has the chela robust (Fig. 38) like the male of C. variegatus. However, these two species cannot be confused, because C. variegatus has the movable finger of pedipalp with 13–15 cutting edges composed of granules, whereas C. solegladi sp. n. has the movable finger with 7 or 8 cutting edges composed of granules.
