TYPE LOCALITY AND TYPE REPOSITORY. India, Uttarakhand (formerly Uttaranchal) State, ca 15 km NE of Mussoorie, Dhanaulti (30.40°N 78.19°E) env., 2250 m a.s.l. GoogleMaps ; FKCP.

TYPE MATERIAL. India, Uttarakhand (formerly Uttaranchal) State, ca 15 km NE of Mussoorie, Dhanaulti (30.40°N 78.19°E) env., 2250 m a. s. l., 1 August 2003, 1♀ (holotype), leg. Z. Kejval & M. Trýzna. GoogleMaps

ETYMOLOGY. The species epithet is a patronym honoring a Czech entomologist Miloš Trýzna, one of the collectors of holotype of the new species.

DIAGNOSIS (♀). Total length 61 mm. Base color uniformly reddish black to black, telson and legs reddish brown. Pectinal teeth number 6 in female, fulcra absent; a pecten forms one compact unit with an incomplete furrow between places for marginal and middle lamellae. Patella of pedipalp with 17 (5 eb, 2 esb, 2 em, 4 est, 4 et) external and 7 ventral trichobothria. Chela of pedipalp with 4 ventral trichobothria located on ventral surface. Chelal trichobothrium Eb 3 is located in proximal half of external surface in line with Dt. Fingers of pedipalps flexed in female. Chela length to width ratio 3.13 in female. Pedipalp movable finger with 9 IAD, ca 74 MD, 4 ID and 11–13 OD present. Tarsomere II of legs with 7–8 stout median ventral spines in a row and two other parallel spines. Telson rather bulbous and smooth, length to depth ratio 2.85 in female; annular ring present.

DESCRIPTION (♀). Total length 61 mm of female holotype, male unknown. The habitus is shown in Figs. 132–133 View Figures 132–136 . For position and distribution of trichobothria of pedipalps see Figs. 137–143 View Figures 137–146 . Fingers of pedipalps are flexed in female ( Fig. 138 View Figures 137–146 ).

Coloration ( Figs. 132–133 View Figures 132–136 ). The base color is uniformly reddish brown to black. The telson and legs are reddish brown but lighter than mesosoma. Chelicerae are reddish black and reticulate.

Carapace and mesosoma ( Figs. 147–150 View Figures 147–155 ). The entire carapace is covered with large and minute granules; carinae are absent. The anterior margin of the carapace is markedly depressed, convex in the middle. The carapace bears three lateral eyes. The mesosoma is granulated, with one median carina. Tergite VII is pentacarinate. The sternites are smooth with two parallel furrows except sternite VII, which bears four sparsely granulate carina. Pectinal teeth number 6 in female, fulcra are absent. A pecten forms one compact unit with an incomplete furrow between places for marginal and middle lamellae.

Metasoma and telson ( Figs. 134–136 View Figures 132–136 , 151 View Figures 147–155 ). The metasoma is very sparsely hirsute and granulated, with relatively large granules. Metasomal segment I with 10 carinae, II–IV with 8 carinae, and V with 5 carinae. The median lateral carinae of metasoma V are indicated by isolated granules that may coalesce into carinae. The dorsolateral carinae of segments III and IV are granulate with sharp granules, which are not posteriorly terminated with a pronounced tooth. The telson is rather bulbous and smooth, with annular ring present.

Pedipalps ( Figs. 137–146 View Figures 137–146 ). The pedipalps are very sparsely hirsute. The patella bears 17 (5 eb, 2 esb, 2 em, 4 est, 4 et) external and 7 ventral trichobothria. The chela bears 4 ventral trichobothria located on the ventral surface. The femur and patella are granulated. The femur has 5 granulose carinae and the patella has 5 complete carinae with dorsal and ventral patellar spurs present. The manus dorsally bears granules, which are in the central part replaced by large granules forming a longitudinal irregular incomplete carina. The external surface of the chela is covered by minute and larger sparse granules, which form another complete median carina. The movable fingers with 9 IAD, ca 74 MD; there are also 4 ID and 11–13 OD present.

Legs ( Figs. 152–155 View Figures 147–155 ). The tibia and tarsomeres of legs with several setae not arranged into bristlecombs on dorsal surfaces but with rows of spines on dorsolateral and ventrolateral surface. Tarsomere II of legs I–IV with 7–8 stout median ventral spines in a row and two other parallel spines. The femur bears 3–4 and patella, 4–5 incomplete carinae; both femur and patella are finely granulated.

Measurements. See Table 2.

AFFINITIES. The described features distinguish S. tryznai sp. n. from all other species of the genus. S. tryznai sp. n. is very similar to S. vonwicki Birula, 1913 . It is possible to differentiate these two species according to pecten morphology. S. vonwicki has fulcra present ( S. tryznai sp. n. has fulcra absent). S vonwicki has separate, formed marginal lamellae I and III; marginal lamella II is not defined but forms a single compact unit with middle lamella. In S. tryznai sp. n., a pecten forms one compact unit with an incomplete furrow between places for marginal and middle lamellae. Trichobothria Dt and Eb 3 are located more basally in S. vonwicki ( Figs. 161–162 View Figures 161–169 versus 137–138). Also, localities of these two species are far apart.
