Diagnosis A medium-sized, yellow member of the fallaxHNS group, distinguished as follows:

Major: head heart-shaped; propodeal spines reduced to denticles; postpetiolar node seen from above roughly trapezoidal; mesonotal convexity prominent, and in dorsal-oblique view seeming to "lean" posteriorly; carinulae on frontal lobes restricted to lateral halves, and rest of cephalic sculpturing confined to the level of the eyes and capsule anterior to them.

Minor: occiput very broad, lacking nuchal collar; humerus angulate; sculpturing on head limited to anterior fourth of dorsal surface. Most similar to and possibly synonymous with dioneHNS.
