Figs 1–2

Diagnosis

This species is closest to O. apperti , but can be differentiated from it by the following characters: presence of a horn on T1, A3 and A4 subequal in length and T3 medially punctate; in O. apperti : T1 without horn, A3 more than 2 × the length of A4, and T3 medially longitudinally costate on anterior half, smooth with setigerous punctae on posterior half.

Etymology

This species is named in honour of Dr Agnièle Touret-Alby, Curator, MNHN.
