Diagram of head of male of Lecanidin (after Signoret), both dorsal and ventral aspects being shown together.

This insect belongs to Signoret's first series: the dorsal spots distinguish it from L. hesperidum.

The very numerous conical spines distinguish this species from that known as Acanthococcus aceris, Signoret, the European species.

The only difference mentioned by Signoret is the colour and texture of the sac, an unimportant character in this case.
