Description
Male (Fig. 3 View Figure 3 ). PL 6.5, PW 5.3, AW 2.8, OL 6.7, OW 4.2. Eyes: AME 0.34, ALE 0.43, PME 0.39, PLE 0.48, AME-AME 0.23, AME-ALE 0.07, PME-PME 0.28, PME-PLE 0.63, AME-PME 0.40, ALE-PLE 0.46, CH AME 0.16, CH ALE 0.23. Spination: Palp: 131, 101, 2121; Fe: I-III 323, IV 321; Pa: I-IV 101; Ti: I 2026, III-IV 2126; Mt: I-II 1014, III-IV 3036. Measurements of palp and legs: Palp 11.0 (3.3, 1.4, 2.2, -, 4.1), I 36.9 (9.5, 3.2, 10.2, 10.9, 3.1), II 40.2 (10.3, 2.8, 11.6, 12.3, 3.2), III 30.6 (8.2, 2.2, 8.7, 8.9, 2.6), IV 33.4 (8.8, 2.3, 9.0, 10.2, 3.1). Leg formula: II-I-IV-III. Cheliceral furrow with three anterior and four posterior teeth, with 28 denticles. Dorsal prosoma reddish to yellowish-brown, posterior margins dark, with distinct fovea and shallow radial furrows. Chelicerae deep reddish-brown. Sternum yellowish-brown, with margin deep brown. Gnathocoxae and labium deep yellowish-brown, with margin deep brown. Legs yellowish-brown, with dark spots. Dorsal opisthosoma yellowish-brown with distinct bright patch in posterior half. Ventral opisthosoma uniformly yellowish-brown with some irregular patches.
Palp as in diagnosis (Figs 1 View Figure 1 , 2 View Figure 2 ). Cymbium longer than tibia. Conductor curved, arising in 1- o’clock position. Spermophore slightly curved in ventral view. Proximal part of tegulum covering embolus base. RTA arising subdistally from tibia with dRTA distinctly curved in retrolateral view.
Female. For details see Jäger et al. 2002.
Diagnosis
Males of this species resemble those of Sinopoda pyramidalis Zhong, Jäger, Chen & Liu, 2019 ( Zhong et al. 2019: Figs 50A-C and 51A-D) in having the embolus strongly S-shaped and embolic apophysis pointed in distal part, forming a triangle, but can be separated by: 1) embolus arising from tegulum at the 6- o’clock position in ventral view (8:30- to 9- o’clock position in S. pyramidalis ); 2) dRTA narrow and dorsally digitiform in ventral view (broad, bulging in S. pyramidalis ); 3) tegulum covering proximal part of embolus in ventral view (only small part of proximal embolus in S. pyramidalis ) (Figs 1 View Figure 1 , 2 View Figure 2 A-C). Females of this species are similar to those of Sinopoda shennonga (Peng, Yin & Kim, 1996) ( Jäger et al. 2002: Figs. 6-7) in having the lobal septum half the width of the lateral lobe and posterior part of spermathecae considerably larger than glandular projection, but differ from S. shennonga by: 1) epigynal field with distinct anterior bands (indistinct in S. shennonga ); 2) epigyne with lobal pockets connected by an anterior rim (not in S. shennonga ); 3) vulva with internal duct running parallel along the median line (diverging strongly anteriorly in S. shennonga ). Females of this species can also be distinguished from other Sinopoda spp. by anterior vulva with a massive and angled structure (Fig. 2 View Figure 2 D-E, Jäger et al. 2002).
