Achilia tumidifrons group

Jeannel (1962: 398, 402) characterized this group as follows: elytra with 2 basal foveae; basal striae of abdominal tergite I separated by 1/3 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 group currently includes A. larvata ( Reitter, 1885) , A. tumidifrons Jeannel, 1962 , A. globiceps Jeannel, 1962 , and A. paraglobiceps Franz, 1996 . However, we place all of these names as A. larvata , becoming the only constitutive member in the unfortunately named tumidifrons group.
