3137A61DFFBF0B194799AAF8FA9DFE34.taxon	discussion	Remarks. This species is very similar to O. dowwiangkanae, O. peniculatus, O. tuberculatus and O. aureus. Their tegmina are yellow with dark brown band along posterior margin, but differs in the presence of external sclerite of male genitalia (Fig. 15). This species differs from all species above in the supra-anal plate being setose but without strong short hairs standing together as in a brush (Fig. 12 B); and it is also similar to O. citrus, but different in colour of head and cerci. It is also different with O. panda in colouration of body and male genitalia.	en	He, Zhixin, Ma, Ge, Long, Jifeng, Wang, Yan, Zhang, Tao, Ma, Libin (2021): Taxonomy of scaly crickets (Orthoptera: Mogoplistidae: Mogoplistinae) from China: five new species groups and three new species of the genus Ornebius Guérin-Méneville, 1844.
