TYPE LOCALITY AND TYPE REPOSITORY. Myanmar, Chin State, Chin Hills, Myohaung (20.59°N 93.17°E) ; FKCP.

TYPE MATERIAL. Myanmar, Chin State, Chin Hills, Myohaung (20.59°N 93.17°E), IX.2001, 1♂ (holotype), leg. E. Čik , FKCP.

ETYMOLOGY. The species epithet is a patronym honoring Eduard Čik, the collector of holotype of the new species.

DIAGNOSIS (♂). Total length 34 mm. Base color reddish brown to black. Telson and legs yellow to yellowish brown. Pectine teeth number 6–7 in male, fulcra absent. Pectines with 2 marginal and 4 middle lamellae. Patella of pedipalp with 18 (5 eb, 2 esb, 2 em, 4 est, 5 et) external and 8 ventral trichobothria. Chela of pedipalp with 4 V series trichobothria located on ventral surface. Chelal trichobothrium Eb 3 located in distal half of manus between trichobothria Dt and Est. Fingers of pedipalps undulate in female. Chela length to width ratio 3.6 in male. Pedipalp movable finger with ca. 45 IAD which create a second row, parallel with MD (ca. 65 in number). There are also 4 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 with 10 carinae and metasoma II–IV with 8 carinae. Telson elongate and smooth, length to depth ratio 2.9 in male; annular ring developed.

DESCRIPTION (♂ holotype). Total length 34 mm. Female unknown. Habitus as shown in Fig. 363 . For position and distribution of trichobothria on pedipalps, see Figs. 364–369 . Fingers of pedipalps undulate in male ( Fig. 365 ).

Coloration ( Fig. 363 ). Base color uniformly reddish brown to black. Telson and legs yellow to yellowish brown. Chelicerae yellowish brown and reticulate.

Carapace and mesosoma ( Fig. 363 ). Entire carapace covered with both large and minute granules; carinae absent. Anterior margin of carapace with a deep median notch. Carapace with 3 pairs of lateral eyes. Mesosoma granulated, with one median carina. Tergite VII is pentacarinate. Sternites finely granulated with two parallel furrows except sternite VII, which has four sparsely granulate carinae. Pectine teeth number 6–7 in males, fulcra absent. Pectines with 2 marginal and 4 middle lamellae. Metasoma and telson ( Figs. 371–373 ). Metasoma very sparsely hirsute and granulated. Metasomal segment I with 10 carinae, II–IV with 8 carinae, and V with 5 carinae. Median lateral carinae of metasoma V indicated by isolated granules that may coalesce into carinae. Dorsolateral carinae of segments III–IV granulate with sharp granules, which terminate posteriorly with a barely pronounced tooth. Telson elongate and smooth with annular ring developed.

Pedipalps ( Figs. 364–370 ). Pedipalps very sparsely hirsute. Patella with 18 (5 eb, 2 esb, 2 em, 4 est, 5 et) external trichobothria and 8 ventral trichobothria. Chela with 4 V series trichobothria which are located on the ventral surface. Femur and patella granulated. Femur with 5 granulose carinae and patella with 5 complete carinae with dorsal and ventral patellar spurs pronounced. Manus dorsally with fine, rounded granules, which are in the central area replaced by large granules forming a dorsal secondary carina. External surface of chela covered by minute and larger sparse granules which indicate a external secondary carina. Movable fingers with ca. 45 IAD, which form a second row, parallel to MD (ca. 65 in number) and there are also 4 ID and 11 OD present.

Legs. Tibia and tarsomeres of legs with several setae not arranged into bristle combs on dorsal surfaces but with rows of spinules on dorsolateral and ventrolateral surfaces. Tarsomere II of legs I–IV with 6–7 stout median ventral spinules and two pairs of flanking setae. Femur with 3–4 and patella 4–5 incomplete carinae; both femur and patella are finely granulated.

Measurements. See Table 3.

AFFINITIES. The combination of five characters (chelal trichobothrium Eb 3 located in distal half of manus between trichobothria Dt and Est; patella of pedipalp with 8 ventral and 18 external trichobothria; fingers of pedipalps undulate in male; pedipalp movable finger with ca. 45 IAD; and chela length to width ratio 3.6 in male) is unique in the entire genus Scorpiops . The most similar species is S. asthenurus from India and Bhutan which differs by a larger number of IAD (ca. 60 versus ca. 45) and different shape of the chela which is narrower in S. asthenurus (see Figs. 271–272 versus 364–365 and Table 9).

DISTRIBUTION. Myanmar ( Fig. 799 ).
