TYPE LOCALITY AND TYPE REPOSITORY. Thailand, Phetchaburi Province, 2 km N of Ban Sa Yai Non, 12°56' 58"N 99°47'44"E, 40 m a.s.l.; FKCP. TYPE MATERIAL. Thailand, Phetchaburi Province, 2 km N of Ban Sa Yai Non, 12°56'58"N 99°47'44"E, 40 m a.s.l., 16.-18.I.2006, 1&amp;male; (holotype) 1&amp;female; (allotype) 1im. (paratype), leg. S. Be&amp;ccaron;vá&amp;rcaron; and R. Fouqué, FKCP; Trang Province, 20 km E of Trang, XI.1998, 1&amp;female; (paratype), leg. Kozmík, FKCP. ETYMOLOGY. Named after Jára Cimrman, a well known Czech renaissance man. DIAGNOSIS. Total length 31–38 mm. Two pairs of lateral eyes and one pair of median eyes. Chela of pedipalp wide and ampullar, identical in both sexes. Movable finger of pedipalp with 10 or 11 cutting edges. Chela of pedipalp with 7 or 8 granulated carinae. Patella with 5 carinae, femur with 4 or 5 carinae. Pectinal teeth number 4–5. Carapace granulated. Anterior margin of carapace straight to weakly concave. Mesosomal tergites granulated. All sternites smooth, without carinae. First metasomal segment with 6 to 10 carinae, second with 8 to 10 carinae, third and fourth segments with 8 carinae, fifth segment with 7 carinae. Dorsal surfaces of all metasomal segments granulated. DESCRIPTION. Total length 31–38 mm. Two pairs of lateral eyes and one pair of median eyes. The male has relatively larger pectens. The chela of pedipalp is wide and ampullar, identical in both sexes. Pectinal teeth number 4–5. For the position and distribution of trichobothria see Figs. 9–15. Trichobothrium <i>d2</i> of pedipalp patella is located on edge between the dorsal and internal surfaces, and trichobothrium <i>d3</i> is located on the internal surface (Fig. 12). COLORATION. The color is reddish to black, spotted. Legs, pedipalps and telson are red to yellow, lighter than the mesosoma, and spotted. MESOSOMA AND CARAPACE. The entire carapace is covered by large granules, the larger of which form two longitudinal, symmetrical carinae. The anterior margin of the carapace is straight to weakly concave. The mesosomal tergites are granulated, less so in the male holotype and more densely in larger females. All sternites are smooth, without carinae. METASOMA AND TELSON. The first metasomal segment bears 6 to 10 carinae, the second bears 8 to 10 carinae, the third and fourth segments bear eight carinae, and the fifth segment bears seven carinae of which one ventral carina posteriorly branches to form the letter “Y“. All carinae are composed of sparse and denticulate granules. The spaces between carinae are irregularly granulated on all surfaces. Granules on the dorsal surface may form a pair of carinae. All segments are sparsely hirsute. The telson is elongate, smooth and sparsely hirsute. PEDIPALPS. The movable finger has 10 (male holotype) or 11 (female allotype) cutting edges (Fig. 16). The chela has seven or eight granulated carinae. The carina on the externolateral surface of chela may be incomplete. The patella has five carinae and the femur has four or five carinae. All carinae consist of granules. The spaces between carinae are covered by unevenly spaced small granules that form a reticulate pattern on the dorsal surface of the chela. LEGS. The legs are hirsute, without bristlecombs and carinae. The femora are granulated, and solitary granules may be present also on the patella. MEASUREMENTS IN MM. Total length of <i>male holotype</i> 31; carapace length 4.3, width 4.3; metasoma and telson length 16; first metasomal segment length 1.8, width 2.1; second metasomal segment length 1.9, width 1.9; third metasomal segment length 1.9, width 1.9; fourth metasomal segment length 2.2, width 1.8; fifth metasomal segment length 3.8, width 1.7; telson length 4.3; pedipalp femur length 2.9, width 1.4; pedipalp patella length 3.2, width 1.6; chela length 6.7; manus width 3.1; movable finger length 3.5. Total length of <i>female allotype</i> 38; carapace length 5.1, width 5.2; metasoma and telson length 17.7; first metasomal segment length 1.6, width 2.7; second metasomal segment length 2.1, width 2.3; third metasomal segment length 2.2, width 2.2; fourth metasomal segment length 2.4, width 2.1; fifth metasomal segment length 4.4, width 2; telson length 5; pedipalp femur length 3.5, width 1.7; pedipalp patella length 3.6, width 1.9; chela length 7.7; manus width 3.9; movable finger length 4.3. AFFINITIES. The described features distinguish <i>C. cimrmani</i> <b>sp. n.</b> from all other species of the genus. They are recounted in the key. Morphologically closest is <i>C. cavernicola</i>, with which the female paratype was formerly confused (see Kova&amp;rcaron;ík, 2000: 42). However, these two species can be easily separated, because <i>C. cavernicola</i> has the dorsal surfaces of metasomal segments smooth, especially the fourth and fifth segments, whereas <i>C. cimrmani</i> <b>sp. n.</b> has all metasomal segments dorsally granulated. The movable finger of pedipalp has 12–14 cutting edges in <i>C. cavernicola</i> and only 10–11 cutting edges in <i>C. cimrmani</i> <b>sp. n.</b>
