Camponotus vitiosus
A small black carpenter ant with a brownish pronotum, the representative species of the subgenus Myrmamblys in Japan. Nests in trees.
Camponotus vitiosus is a carpenter ant of the subgenus Myrmamblys described by F. Smith in 1874 from Hyogo (Hiogo), Japan. Workers measure 5-6mm; the body is black, the legs blackish brown and the pronotum often brownish. The propodeal dorsum bears a distinct notch, and the petiole is thick, appearing as a symmetrical inverted U in profile. The Japanese name dates back to Teranishi's 1915 record; the 1988 Japanese name list treated the species as C. tokioensis, but after later taxonomic review it is now regarded as the distinct species C. vitiosus within Myrmamblys. Like C. quadrinotatus it is a small carpenter ant that nests in trees. Less widely traded than the large carpenter ants, it is known to enthusiasts as a native Camponotus that can be kept in little space.
