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).
