Described by Smith from Borneo. The colour is variable, 

 but specimens from Borneo seem to have the abdomen less 

 strongly suffused with black than in those from New Guinea. 

 I suspect that the New Guinea form is identical with 

 murarius, Sm., from Coram ; but if so, Smith's statement that 

 the petiole is shorter in murarius must be erroneous.
