Material examined.
Holotype ♀ (IZCAS-Ar41647), Thailand, Kanchanaburi Province, Sai Yok District, Wang Krachae Subdistrict, unnamed cave; 14.2036°N, 99.0277°E; 82 m; 11 January 2014; Prasit Wongprom leg.
Diagnosis.
This new species resembles Sinopoda bifurca Grall & Jäger, 2020 ( Grall and Jäger 2020: 11, fig. 4d, e) in having similar lateral lobes, but it can be recognized by the uniquely rectangular lobal septum and the reduced posterior part of internal duct system (Fig. 5A, B View Figure 5 ), whereas the posterior part of internal duct system slightly swollen in S. bifurca .
Description.
Female (holotype, IZCAS-Ar41647) Measurements: PL 3.28, PW 3.24; AW 1.88; OL 4.24, OW 2.64. Eyes: AME 0.12, PME 0.08, ALE 0.14, PLE 0.16, AME-AME 0.10, AME-ALE 0.05, PME-PME 0.18, PME-PLE 0.22, AME-PME 0.13, ALE-PLE 0.15, CHAME 0.11, CHALE 0.15. Palp: 4.72 (1.53, 0.44, 1.34, -, 1.41). Legs: I 15.04 (4.10, 1.66, 4.16, 3.84, 1.28); II 17.61 (5.06, 1.98, 4.93, 4.23, 1.41); III 15.18 (4.23, 1.73, 4.23, 3.65, 1.34); IV 15.43 (4.42, 1.41, 4.10, 3.97, 1.53). Leg formula: II-IV-III-I. Spination: palp: 131 101 2130 3030. Legs: Fe I-IV 323, Pa I-IV 111, Ti I-IV 2026, Mt I-IV 2026. Chelicerae: furrow with three anterior teeth, four posterior teeth, and without denticles.
Copulatory organ: as in diagnosis. Epigynal field slightly wider than long, with two short anterior bands slightly fused with field, with one fusion bubble medially. The width of the lobal septum is equal to 1/3 the width of the epigynal field. The lobal septum is partly fused to the epigynal field. The anterior part of the internal ducts is discernibly swollen. The glandular appendages are blunt and bent at a right angle, extending laterally in posterior half of internal duct system. Internal duct system fused along whole median line. The posterior part of the internal duct system are miniaturized and narrower than anterior part of internal ducts and with the fertilization ducts arising posterolaterally. Unexpanded, membranous sac between fertilization ducts (Fig. 5A, B View Figure 5 ).
Coloration in ethanol: yellowish brown. Prosoma: dorsally yellowish brown with fovea and cuticular with a radial, yellowish-brown pattern. Sternum and ventral coxae pale yellowish brown, gnathocoxae deep yellowish brown, labium reddish brown. Chelicerae deep reddish brown. Legs: yellowish brown. Opisthosoma: including spinnerets, greyish brown to yellowish brown, sparsely covered with brown hairs (Fig. 9E, F View Figure 9 ).
Male: unknown.
