Remarks.

Blattella ligulata (Bey-Bienko, 1957) comb. nov. (Fig. 7 ), originally in the genus Episymploce , was transferred to Symploce by ( Roth 1985c) because of the symmetrical T10. However, both morphological and molecular data analysis support that this species should be in the genus Blattella . Blattella ligulata (Bey-Bienko, 1957) comb. nov. shares some characteristics with Blattella : male T10 tongue-shaped (Fig. 7J ) and T7 specialized with a pair of large pouch-like depressions with a setal tuft between them (Fig. 7G ). In our phylogenetic analysis, Blattella ligulata (Bey-Bienko, 1957) forms the basal clade of Blattella , being the sister of all other Blattella samples (Fig. 1 , supplementary material Fig. S1).

Distribution.

China (Yunnan).

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.
