description: Sinopoda emei spec. nov.
Figs 10 a–b, 57 c–d
Type material: Holotype: female (SD 1630), CHINA: Sichuan Province: Emei-Shan, 1000–2300 m, 25 May–16 June 1998, J. Martens leg. (SMF).
Etymology: The species name is derived from the type locality; term in apposition.
Diagnosis: Females of S. emei spec. nov. are similar to those of S. assamensis spec. nov. (Figs. 3 a–b) in having a wide lobal septum with a median indentation anteriorly and glandular appendages extending posteriorly not in posterior half of internal duct system. They can be distinguished from the latter species by 1. lateral lobes completely fused without median indentation and antero-lateral margins short and running posteriorly (lateral lobes only fused in anterior part, posteriorly with deep median indentation, antero-lateral margins long and horizontal in S. assamensis spec. nov.), 2. glandular appendages nearly about half as wide in S. emei spec. nov. as in S. assamensis spec. nov., 3. posterior part of internal duct system small and bulging laterally (bulging antero-laterally in S. assamensis spec. nov.), and 4. fertilization ducts arising postero-laterally (arising postero-medially in S. assamensis spec. nov.).
Description: Female (holotype): Total length 12.90; prosoma 5.60 long, 4.70 wide, anterior width of prosoma 3.00; opisthosoma 7.30 long, 4.90 wide. Eye measurements: AME 0.22; ALE 0.37; PME 0.30; PLE 0.41; AME–AME 0.20; AME–ALE 0.08; PME–PME 0.28; PME–PLE 0.43; AME–PME 0.31; ALE–PLE 0.40; clypeus AME 0.46; clypeus ALE 0.39. Leg formula: 2413. Measurements of palp and legs: palp: 7.50 (2.30, 1.20, 1.70, 2.30); I: 20.30 (5.60, 2.50, 5.70, 4.90, 1.60); II: 22.10 (6.30, 2.60, 6.20, 5.30, 1.70); III: 18.40 (5.40, 2.30, 4.90, 4.30, 1.50); IV: 20.60 (5.80, 2.20, 5.30, 5.50, 1.80). Spination: palp: 131, 101, 2121, 1014; legs: Fe I–III 323, IV 321; Pa I–III 001, IV 000; Ti I–III 2026, IV 2126; Mt I–II 1014, III 2026, IV 3036. Cheliceral furrow with 3 anterior and 4 posterior teeth.
Colouration in ethanol: Prosoma yellowish-brown, posteriorly with yellow longitudinal stripe, posterior and lateral margin brown. Sternum light yellowish-brown. Opisthosoma greyish-brown with yellow dots, anteriorly with yellow spot, ventral part yellowish-grey. Chelicerae reddish-brown. Palps yellowish-brown; Ti and Ta reddishbrown. Legs yellowish-brown; Mt and Ta reddish-brown.
Copulatory organ as in diagnosis. Epigynal field wider than long with two anterior bands, left band longer, without slit sensilla. Lateral lobes posteriorly with median indentation. Epigynal pockets running from latero-median to medio-anterior. Internal duct system wider than long. Spermathecae fused along median line. Glandular appendages and internal duct system slender. Fertilization ducts long and curved, distal part tapering.
Male: Unknown.
Distribution: Known only from the type locality.
