A large, very distinctive member of the fallax group, recognizable as follows.

Major: “orange”; almost all of promesonotal and propodeal dorsa, as well as mesopleuron, covered by transverse carinulae; entire rear third of head, including occiput, rugoreticulate; and almost all the anterior two-thirds of the head carinulate, with no accompanying rugoreticulum; petiolar node from the side very high, strongly tapered toward the apex; postpetiolar node 2! broader than petiolar node from above, and elliptical in shape; body everywhere densely pilose.

Minor: yellow; all of posterior dorsal half of head and all of mesosomal dorsum transversely rugulose; propodeal spine absent; occiput drawn into a neck with broad nuchal collar.
