Black Potter Wasp

Rhynchium atrum


Feb 11, 2015 - ID Updated to Rhynchium atrum following MarcoSelis' ID suggestion. ========= My spotting looks the same with Rhynchium haemorrhoidale, except for the orange coloration of the abdomen of R. haemorrhoidale. Pics 3-4 showing white on the eye due only to camera flash. Rhynchium is an Australian, Afrotropical, Indomalayan and Palearctic genus of potter wasps. Family Vespidae, Subfamily Eumeninae. This Eumenid wasp is almost black all over, with orange antennae, partial orange on its face, thorax, first pair of legs, and wings. There's a mention in the reference link I have on the Notes section, of a subspecies in the Philippines, Rhynchium haemorrhoidale atrum Saussure, but I could not find any photo of it.

Found something similar here in Baguio City but has yellow/gold antennae.

Thank you, MarcoSelis. ID is now updated to Rhynchium atrum.

The clypeus and the anterior part of pronotum are red, so it is R. atrum. R. atrissimum is entirely black with orange antennae.

Thank you for the ID, Wen-ChiYeh.

There were in fact two very similat black Rhynchium species recorded from PH, i.e., R. atrum and R. atrissima according to the Vecht's article. Your photos look very similat to those I taken in Taiwna whose ID I gave was R. atrissima.
