Type material: Holotype: female (SD 1567), LAOS: Vientiane Province: Vang Vieng, cross Nam Song, Tham Xiang , N18°54.550’, E102°26.537’, 270 m, in cave, by hand, 03 December 2012, P. Jäger leg. ( SMF). GoogleMaps
Etymology: The species name is derived from the Lao word “aenyk” meaning “separate” and referring to the separated spermathecae; term in apposition.
Diagnosis: Females of S. aenyk spec. nov. are similar to those of S. kieo spec. nov. ( Figs. 21 View FIGURES 21 a–d) in having strongly developed lateral lobes, glandular appendages extending anteriorly and situated ventrally of internal duct system and a separated and simple internal duct system with narrow ducts inside. It can be distinguished from the latter species by 1. lateral lobes fused with visible seam running from epigastric furrow to copulatory opening, posterior part with small, deep median indentation, anterior part bulging anteriorly (lateral lobes fused without visible seam, anterior part not bulged, posterior part with wide median indentation in S. kieo spec. nov.), 2. copulatory atrium (only about half the size in S. aenyk spec. nov. as compared to S. kieo spec. nov.), 3. glandular appendages only visible in ventral view (also visible in dorsal view in S. kieo spec. nov.) and 4. fertilization ducts with distal part wider than proximal part (proximal part as wide as distal part in S. kieo spec. nov.).
Description: Female (holotype): Total length 11.40; prosoma 5.30 long, 4.60 wide, anterior width of prosoma 3.30; opisthosoma 6.10 long, 3.70 wide. Eye measurements: AME 0.24; ALE 0.39; PME 0.28; PLE 0.40; AME–AME 0.27; AME–ALE 0.12; PME–PME 0.37; PME–PLE 0.49; AME–PME 0.40; ALE–PLE 0.45; clypeus AME 0.45; clypeus ALE 0.41. Measurements of palp and legs [I & II: missing]: palp: 7.35 (2.05, 1.20, 1.70, 2.40); III: 18.35 (5.30, 2.15, 5.00, 4.40, 1.50); IV: 20.10 (5.60, 2.00, 5.30, 5.40, 1.80). Spination: palp: 131, 101, 2121, 2024; legs: Fe III 323, IV 321/421; Pa III–IV 000; Ti III–IV 2026; Mt III 3006, IV 3036. Cheliceral furrow with 3 anterior and 4 posterior teeth.
Colouration in ethanol: Prosoma yellowish-brown, medially reddish-yellow, lateral margin dark brown, laterally and posteriorly with dark brown U-shaped pattern. Sternum yellowish-white. Opisthosoma yellow with brown spots, posterior part dark brown, medially with six brown dots, ventral part yellowish-brown. Chelicerae dark red- dish-brown with light brown stripes. Palps yellowish-brown; Ti and Mt reddish-brown. Legs yellowish-brown; Fe medially and distally, Pa laterally and distally, Ti proximally brown.
Copulatory organ as in diagnosis. Epigynal field wider than long, without anterior bands and slit sensilla. Lateral lobes bulging extremely ventrally. Lobal septum present in posterior part of epigyne, anterior part wider than median part. Fusion bubbles situated at median and posterior part of epigyne. Copulatory atrium absent in anterior half. Internal duct system wider than long. Glandular appendages rounded. Fertilization ducts situated posteriorly.
Male: Unknown.
Distribution: Known only from the type locality.
