Description
DIAGNOSIS A member of the tachigaliae group, characterized by 11-segmented antennae, and distinguished within it as follows.
Major: in side view, pronotal profile broken by a sharp obtuse angle; rugoreticula present mesad and laterad to eye; all of dorsum of head posterior to eye transversely carinulate except for antennal scrobes, which are smooth;humeri and anterior pronotal margin rugoreticulate; postpetiole from above very broad and narrowly elliptical in shape.
Minor: space between eyes and antennal fossae carinulate, foveolate, and opaque; rest of head smooth and shiny; in full-face view, a single, very long curving hair extends from each occipital corner; eye oval and set well forward on the head.
