Figs 25–26
Material examined
INDIA – Tamil Nadu • 1 ♂; Dharmapuri, Hosur, Uddanapalli; 12°37′28″ N, 77°55′29″ E; alt. 758 m; 29 Nov. 2014; SN; ICAR-NBAIR P3961 • 1 ♂; same collection data as for preceding; ICAR-NBAIR P3962.
Remarks
This species is similar to O. vikata but differs from it in these characters: in Odontoscelio sp. 3. the occiput is transversely carinate, the carinae on the frons are smooth,the antennomeres are short (A3, A6, A7 <3× as long as wide). In O. vikata the occiput is foveate, the carinae on the frons are ribbed and the antennomeres are elongate (A3, A6, A7>3.8× as long as wide).
As no females were collected this is not currently being described as a new species.
