Additional material examined.

2 ♂, 7 ♀ (HBU), Tiantangzhai National Forest Park (30°24'01.37"N, 115°18'19.31"E), Hubei, China, 8 September 2012, Fengxiang Liu, Jie Liu and Dan Quan leg.

Diagnosis.

Male of Sinopoda serrata is similar to Sinopoda albofasciata Jäger & Ono, 2002 in having the unbifurcated RTA, the slightly bent tip of embolus, but can be distinguished from the latter by the following characters: 1. RTA massive, but small in Sinopoda albofasciata ( Jäger and Ono 2002); 2. The embolic apophysis (EA) distinctive, lamellar, but reduced in Sinopoda albofasciata ( Jäger and Ono 2002) (Figs 1-3, 6-8). Female of Sinopoda serrata is similar to Sinopoda undata Liu, Li & Jäger, 2008 in having the fused lateral lobes (LL), the square-shaped membranous sac unexpanded (MSu), but can be distinguished from the latter by the following characters: 1. Lobal septum (LS) of epigyne significantly short, but long in Sinopoda undata ( Liu et al. 2008); 2. Internal duct system significantly wider than long, its left part widely separated from right part, but slightly wider than long in Sinopoda undata , its left part closed to right part ( Liu et al. 2008) (Figs 4-5, 9-10).

Epigynal field wider than long. Lateral lobes (LL) fused, posteriorly with median incision. Epigynal pockets running from latero-posterior to medio-anterior, where copulatory openings are situated. Lateral furrows (LF) distinct, running to lateral margins of lateral lobes. Lobal septum (LS) wide, significantly short. Internal duct system significantly wider than long, its left part widely separated from right part. Glandular appendages (GA) small, extending not in posterior half of internal duct system. Posterior part of spermathecae (PP) strongly short, bulging slightly laterally. Fertilization ducts (FD) arising posterio-laterally. Membranous sac between fertilisation ducts unexpanded, almost square-shaped (Figs 4-5, 9-10).

Colouration in ethanol (Fig. 12) as in male.

Remarks.

There is a small difference between the holotype male and the new collected materials: the middle part of RTA slightly covered the cymbium from the ventral view in the new collected materials, but not in the holotype (Figs 2, 7, 14).
