Diagnosis.

Males with two pairs of frontal and one pair apically globular orbital setae. Frontal plate and frontal-orbital plates silver-white dusted. Dorsocentral setae (with the exception of the postsutural posterior pair) appearing setulae-like, making them almost indistinguishable from the preceding and surrounding setulae. Trochanters dark amber in colour. Preapical dorsal and anterodorsal setae on hind tibia absent.
