B . Habitus, showing axillular spines. C . Head and pleuron. 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. Fig. 26. Odontoscelio sp. 3. ♂ (ICAR-NBAIR P3961). A . Frons. B . Vertex. C . Head and mesonotum. D . Antenna.
