Enneamerus

Identification
Radchenko and Dlussky (2017) - The genus is characterized by its 9-segmented antennae with 3-segmented club, by the presence of antennal scrobes, and by its poorly developed, subvertical frontal lobes that expose the antennal sockets in full-face view. Besides this, the mandibles have well developed, quite wide masticatory margins armed with six teeth, the propodeum bears two moderately long spines, the middle and hind tibiae lack spurs, and the mesosoma is coarsely reticulated.
