In the genus Ortonia, signoret, the female possesses a rostrum and mentum.
The insect belongs to signoret's fourth series, and may perhaps be only a large variety of L. hemisphricum.
This insect belongs to signoret's first series: the dorsal spots distinguish it from L. hesperidum.
Antenn (according to signoret) with sometimes six, sometimes seven, joints.
The only difference mentioned by signoret is the colour and texture of the sac, an unimportant character in this case.
The very numerous conical spines distinguish this species from that known as Acanthococcus aceris, signoret, the European species.
