Episymploce maxima Li, Liu, Qiu et Yue, 2020: 40.

Material examined.

CHINA • 1 ♂, 1 ♀; Guangxi Prov, Guiping City, Longtan National Forest Park ; 386 m; 2 June 2014; Shunhua Gui, Xinran Li leg. • 1 ♂, Guizhou Prov., Qiannan Dushan County, Mawei Town ; 9 June 2019; Lu Qiu, Wenbo Deng leg. • 1 ♂, Guizhou, Prov., Leishan County, Changbei Village ; 8 June 2013; Guiqiang Huang, Xiangxiang Zhang leg.

Remarks.

Li et al. (2020) established Episymploce maxima , but we transfer this species (Fig. 3 ) to Symploce based on the following reasons: 1) in morphology, body size large (Fig. 3A-D ), T9 unspecialized, and no incrassate or crimping on the posterior margin of the subgenital plate (Fig. 3N ); 2) in phylogenetic analysis, Episymploce maxima Li, Liu, Qiu and Yue was placed as the sister of Symploce sphaerica with a high support value (Fig. 1 , supplementary material Fig. S1), forming a clade together with other Symploce species. In addition, different individuals of this species exhibit some variations in body color, especially on the pronotum: the sample from Duwei County are black brown (Fig. 3A, B ), others from Leishan County are yellowish brown (Fig. 3C, D ).

Distribution.

China (Guangxi, Guizhou).

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.
