Figs 24 a–b, 59 i–j

Type material: Holotype: female (SD 1617), MYANMAR: Kachin State: Sadon ( Fort Harrison ) 1371 m, Malaise trap, 01 July 1934 ( NHRS).

Etymology: The species name is derived from the Burmese word “kyee“ meaning “large” and referring to the huge body size of the female; term in apposition.

Diagnosis: Females of S. kyee spec. nov. are similar to those of S. cochlearia Zhang et al., 2015 and S. taa Jäger, 2012 in having long glandular appendages extending posteriorly on posterior half of the internal duct system. They can be distinguished from S. cochlearia by 1. lobal septum with anterior part wider than median part (median part wider than anterior part in S. cochlearia ), 2. sclerotised bulges lateral of lobal septum (absent in S. cochlearia ), 3. lateral lobes with deep median indentation (without indentation in S. cochlearia ) and 4. posterior part of the spermathecae not spherical (spherical in S. cochlearia ); from S. taa by 1. lobal septum with anterior part wider than median part (median part wider than anterior part in S. taa ), 2. sclerotised bulges besides lobal septum (absent in S. taa ), 3. lateral lobes posteriorly with deep median indentation (posteriorly with slight median indentation in S. taa ), 4. glandular appendages with distal part curved (distal part straight in S. taa ) and 5. fertilization ducts short and tapering (long and leaf shaped in S. taa ).

Description: Female (holotype): Total length 23.30; prosoma 10.30 long, 9.00 wide, anterior width of prosoma 5.60; opisthosoma 13.00 long, 8.30 wide. Eye measurements: AME 0.45; ALE 0.66; PME 0.48; PLE 0.65; AME–AME 0.40; AME–ALE 0.15; PME–PME 0.52; PME–PLE 0.79; AME–PME 0.65; ALE–PLE 0.71; clypeus AME 0.70; clypeus ALE 0.58. Leg formula: 2143. Measurements of palp and legs: palp: 13.70 (3.90, 2.40, 3.00, 4.40); I: 34.30 (9.70, 4.70, 9.60, 7.90, 2.40); II: 37.00 (10.80, 4.90, 10.20, 8.60, 2.50); III: 32.10 (9.40, 4.20, 9.10, 7.10, 2.30); IV: 33.80 (9.70, 3.90, 9.20, 8.40, 2.60). Spination: palp: 131, 101, 2121, 1014; legs: Fe I–III 323, IV 331; Pa I–III 001, IV 000; Ti I–IV 2026; Mt I–II 1014, III 2016, IV 3036. Cheliceral furrow with 3 anterior and 4 posterior teeth.

Colouration in ethanol: Prosoma reddish-brown, medially with brown stripes, posterior part with transversal yellow-brown stripe. Sternum reddish-brown with brown margin. Opisthosoma reddish-brown, anterior part with yellow cross-shaped pattern, medially with six yellow dots, posterior part with yellow spot, ventral part medially yellowish-brown, laterally brown with yellow spots. Chelicerae dark brown. Palps reddish-brown. Legs reddishbrown; Fe ventrally brown.

Copulatory organ as in diagnosis. Epigynal field wider than long, without anterior bands and slit sensilla. Epigynal pockets running from latero-posterior to medio-posterior. Lobal septum anteriorly with small median indentation. Sclerotised bulges posteriorly wide beside lobal septum. Internal duct system longer than wide. Spermathecae fused along median line, posterior part slightly bulging laterally. Glandular appendages long with posterior part slightly wider. Fertilization ducts arising postero-laterally.

Male: Unknown.

Distribution: Known only from the type locality.
