Coccographis nigrorubra Lesne, 1901:349 .

Distribution in China. Yunnan.

Other distribution. Vietnam.

Host plants: Unknown.

Remarks: We have checked 128 specimens of Coccographis nigrorubra collected in Yunnan, and found this species shows very strong sexual dimorphism. The posterior margin of the last abdomen segment is obviously emarginated in the male (Fig. 6E) but straight in the female (Fig.6F); antennal club with four antennomeres in the male (Fig. 6G), but three in the female (Fig. 6H); size of the last antennomere in male distinctly smaller than the other three segments; mean body length 13.4 mm (n = 20) and almost same between male (11.3–17.7 mm, n = 10) and female (10.5–17.3 mm, n = 10). Figure 6 provides the first published photographs of the male (Fig. 6C) and female (Fig. 6D) genitalia of the species, and of any member of the Psoinae . It further confirms the very strong sexual dimorphism of this species. Aedeagus of male long, well sclerotized; parameres V shape; penis long, gently tapering apically (Fig. 6C).
