Comments

Dessart (1979b) described this species from a single female specimen. In his publication, he explains that he placed the species in the genus Dendrocerus mainly because of the ocellar triangle, which is an isosceles triangle and has a broad base in this species, whereas in species of Conostigmus the ocellar triangle is more equilateral. He notes that the species also lacks a sternaulus, which is sometimes present in Conostigmus but always absent in Dendrocerus . However, he does admit that the species bears similarities to the genus Conostigmus , notably in the scape, the presence of the supraclypeal depression, and the slim appearance of the noutalices and the mesosoma ( Dessart 1979b).

The single female specimen is card mounted ( MNHN EY25348), with two slide preparations (prép. no. 7707/081) of the right antenna ( MNHN EY22455) and the right fore and hind wings ( MNHN EY22456).
