Comments. The population of Batraxis bicolor from Hainan has reddish brown head, pronotum, and elytra and a much darker abdomen (Wang et al. 2016) which is stable in all available individuals, while the population from Yunnan ( Fig. 6 View FIGURE 6 B) are uniform in color (darkish brown). Furthermore, the aedeagal endophallus of the population from Hainan is strictly symmetric, but in the population from Yunnan, it is slightly asymmetric ( Fig. 13 View FIGURE 13 A–C). The above differences are interpreted as intraspecific variation of this species. Otherwise, the long protuberance of the protrochanters ( Fig. 14 View FIGURE 14 U) and small preapical tooth of the protibiae ( Fig. 14 View FIGURE 14 E) are stable in both populations. Batraxis bicolor is similar to B. splendida Nomura from Japan and Korea, but the latter species lack a protuberance on the protibiae.
Measurements of the population from Yunnan: male—BL 2.00– 2.17 mm, HL 0.42–0.43 mm, HW 0.42–0.43 mm, PL 0.39–0.42 mm, PW 0.43–0.47 mm, EL 0.50–0.54 mm, EW 0.83–0.84 mm, AL 0.71–0.79 mm, AW 0.78– 0.85 mm, width between discal carinae of tergite IV 0.38–0.44 mm at apices, length of the aedeagus 0.49 mm; female—BL 1.83–2.05 mm; HL 0.38–0.40 mm; HW 0.39–0.40 mm; PL 0.35–0.39 mm; PW 0.42–0.44 mm; EL 0.45–0.49 mm; EW 0.74–0.81 mm; AL 0.65–0.77 mm; AW 0.74–0.82 mm; width between discal carinae of tergite IV 0.38–0.42 mm at apices.
Distribution. China: Yunnan (new provincial record), Hainan ( Fig. 15 View FIGURE 15 ).
