Lithomelissa (Acromelissa) acutispina Clark and Campbell, 1942

Lithomelissa (Acromelissa) acutispina n. sp., Clark and Campbell, 1942, pl. 9, fig. 21.

Remarks. It is not possible to tell from the original description nor illustration whether this species has an apical spine passing freely through the cephalis, so its assignment to Lithomelissa will need to be confirmed by examination of the type material.
