Achilia bifossifrons group

Jeannel (1962: 397, 404) characterized this group as follows: elytra with 3 basal foveae; basal striae of abdominal tergite I separated at most by 1/4 of tergal width; head with broad transverse occipital hump in male; frons not narrowed anteriorly in female; male antennomere X not enlarged; copulatory pieces of aedeagus thin. The only member of this group has always been Achilia bifossifrons .
