Major: dark yellow; rugoreticulum absent on head; all of posterior dorsal surface of head foveolate and opaque, but posterior lateral surface smooth and shiny; carinulae along midline of head extends halfway between eye level and occiput; transverse carinulae present on anterior edge of pronotal dorsum; all of mesosoma and waist foveolate; all of central strip of first gastral tergite shagreened; pronotal dorsum in dorsal-oblique view subangulate, not bilobous; a few long, sparse hairs present on dorsal surface of head, but mesosoma almost completely bare; propodeal spiracle elliptical.

Minor: head, mesosoma, and waist completely foveolate and almost bare of pilosity; anterior half of first gastral tergite shagreened; anterior propodeal face drops precipitously to metanotum in dorsal-oblique view.
