Diagnosis

Cteniogaster hexomma  sp. nov. differs from all other Cteniogaster  gen. nov. species by the consistent absence of PME, by a male palp with a small, straight and pointed RTA and a simple, blunt and scoopshaped rl apical MA, and by the vulva with large, touching, oval ST 1 with conspicuous internal spikes and smaller, more dorsally positioned posterior ST 2 carrying an anterior porous glandular structure.

Etymology

The species name is a noun in apposition and refers to the consistent absence of PME in this species, resulting in an array of six eyes.
