Notes.

Orthogonalys centrimaculata Bischoff, 1951, from N. Vietnam (Sa Pa, Lao Cai) will run in the key to O. robusta , but its vertex has a medio-posterior pale patch (absent in O. robusta ), the mesoscutum is very finely and densely transversely rugulose or coriaceous, matt (mainly finely remotely (rugulose-)punctate and with satin sheen), and hind tibia and tarsus are yellowish brown (dark brown). It runs to O. formosana if only the colouration of the vertex is considered, but it has the mesoscutum is very finely and densely transversely rugulose or coriaceous, matt (coarsely punctate and shiny in O. formosana ) and hind tibia yellowish brown (apical two-thirds dark brown).
