This species is easily separated from other members of the fulvicorne - fratellum group occurring in eastern Asia by a combination of the following character states: male clypeus with a yellow spot on lower half; mesoscutum with coarse reticulate PP on anterior half in both sexes; metapostnotum short, nearly as log as metanotum in both sexes; and the disc of T1 with distinct dense fine PP in both sexes.
