Comments. Josifov & Kerzhner (1978) listed Pyrrhocoris tibialis Stål among the synonyms of Pyrrhocoris sibiricus without any comment on this action. This synonymy has been accepted by most of the subsequent authors (cf. Kerzhner 2001; Gapon 2007a, b; Rédei et al. 2009). However, Liu (1981) treated P. tibialis as a valid species in the handbook to identification of Chinese insects. Following Liu (1981), P. tibialis is still considered valid by some authors (e.g., Zhang 1985, Krajíček et al. 2016, Zhang et al. 2019).
Gapon (2007a, b) described male and female genitalia of five of the six valid species of Pyrrhocoris (see Kerzhner 2001), including those of P. sibiricus. My dissection of a male of P. tibialis from the Nankai University Campus, Tianjin, China, revealed the structure of the aedeagus (Figs 8–9) to be identical to illustrations of P. sibiricus by Gapon (2007a, b). Also the structure of the genital capsule (Fig. 6) and paramere (Fig. 10) are identical to the figures of P. sibiricus provided by Kanyukova (1982), which confirms the synonymy of P. sibiricus and P. tibialis as proposed by Josifov & Kerzhner (1978).
