urn:lsid:zoobank:org:act:909052D7-7052-45E0-85E2-C970C0CD4EF8

Figs 3–4

Diagnosis

This species is very distinct because of the presence of semicircular carinae on the frons and 11 spines on mesosoma.

Etymology

This species is named ‘spinosus’ indicative of the 11 spines present on the mesosoma.
