Measurements (mm).

Overall length: ♂ 17.7-18.0; pronotum length × width: ♂ 3.8 × 4.2; tegmina: ♂ 15.0-15.2.

Redescription.

Male. Coloration: Medium body, yellowish brown (Fig. 6A, B ). Ocelli pale yellow; base of antenna brown, the rest dark brown (Fig. 6C ). The fourth and fifth maxillary palps dark brown, the rest yellow brown (Fig. 6E ). Pronotum yellowish with a pair of reddish-brown V-shaped stripes, and lateral border yellowish brown (Fig. 6D ). Head: Interocular space less than the distance between ocelli and narrower than width of antennal sockets (Fig. 6C ). First three segments of maxillary palps almost the same length (Fig. 6E ). Pronotum subelliptical, hind margin slightly convex in the middle (Fig. 6D ). Tegmina and hindwings: Both fully developed, extending beyond the end of abdomen (Fig. 6H, I ). RP of hindwings with branches near the middle; M simple and unbranched; CuA with 3 complete branches and many small incomplete branches, apical triangle small but visible (Fig. 6I ). Legs: Front femur Type A3 (Fig. 6F ), pretarsal claws symmetrical and unspecialized, pulvillus present. Abdominal tergites: T1 unspecialized, T7 specialized with a pair of shallow fossae (Fig. 6G ), lateral plates of T9 similar. T10 symmetrical and trapezoidal. Paraprocts: Dissimilar, base of right one with a curved and long spine-like process; left one with a curved finger-like process on which three small thorns are situated (Fig. 6J ). Subgenital plate: Asymmetrical, both margins curly and covered with thin thorns. Left stylus bifurcated and obtuse angle present; right stylus near the left one, with 2 or 3 branches near the apex (Fig. 6N ). Male genitalia: L3 on left side, and apex with a deep incision (Fig. 6K ); L2vm rod-shaped and apex branched (Fig. 6L ); R2, R3 consisting of several irregular sclerites (Fig. 6M ). - Female. Unknown.

Remarks.

Wang and Che (2013) suggested that Symploce wulingensis Feng and Woo, 1993 should be transferred to Episymploce according to the morphological characters. In this paper, we also consider it more appropriate to move this species to Episymploce on basis of the morphological information: body size medium, T7 specialized with a pair of shallow fossae without setae, subgenital plates lightly incrassate and setaceous. Our phylogenetic analysis also supports this view (Fig. 1 , supplementary material Fig. S1): Symploce wulingensis Feng and Woo was placed as the sister of Episymploce torchaceus , which together were deeply embedded within the clade of Episymploce .

Distribution.

China (Fujian, Guangdong, Hainan, Guangxi, Sichuan, Guizhou, Chongqing).

Figures

Figure 1. Maximum likelihood (ML) tree based on three mitochondrial genes 12 S rRNA, 16 S rRNA, COII and two nuclear genes 28 S rRNA, histone H 3. The topologies yielded by Bayesian inference (BI) are almost identical with ML tree (see supplementary material Fig. S 1). Branch labels provide bootstrap support (bs) of nodes in ML and posterior probability (pp) (%) of nodes in BI; (*) indicates the branch label of the corresponding analysis is 100 or 1.0, respectively; (-) means the node is absent for the given analysis.
