Lachesilla

Lachesilla pedicularia, photographed by Alby Oakshott.

Belongs within: Lachesilloidea.

Lachesilla is a speciose genus of barklice with very sparse and short ciliation on the forewing and a distally open phallosome in the males. The type species L. pedicularia is mostly associated with fallen vegetation, including dead grasses, and has a global distribution as a result of being transported with harvested grain crops (Mockford 1993).

Characters (from Mockford 1993): Ocelli present. In forewing, Rs fork stem only slightly curved; veins Cu1a free from M. Phallosome with base an apodeme or two separate apodemes; aedeagal arch absent, external parameres absent as such. Hypandrium usually bearing pair of lateral processes ('claspers'). Ovipositor valvulae: v3 usually rounded at apex, occasionally pointed but point never spinose.
