Major: dorsal surface of head, except for frontal triangle and midclypeus, completely covered with carinulae; pronotum covered by “wraparound” carinulae that circle the dorsum to travel along the lower lateral margin; in dorsal-oblique view propodeum descends anteriorly to metanotal groove through a steep face; propodeal spine almost half as long as propodeal basal face and almost vertical to it; postpetiole from above bluntly spinose.

Minor: widely spaced carinulae cover almost all the dorsal surface of the head, including occiput; center of mesopleuron and center of side of propodeum with longitudinal carinulae; occiput broad, lacking nuchal collar.
