male: Head: Eyes bare. Frons matt black, dulled by microsculpture, parallel sided on its central part where it is approximately two thirds eye width, frontal and interfrontal setulae very short, only about one tenth the length of orbital setae, slightly longer setulae present on the anterior margin. Orbital plate also slightly dulled by microsculpture, bare of setulae. Lunule with three / four setulae present on each side, ground colour light brown but covered with intense silver dusting. Face and parafacials also silvered. Anterior genal setulae in a single row of five along mouth margin, the basal two strong and setae-like, by far the strongest setulae on the genae. Second antennal segment reddish-brown. Antennal flagellomere entirely black, just with a trace of brown at extreme base on inner surface, about two and a half times as long as deep. Arista yellow on the basal third, long plumose, plumosity at its maximum extent almost one and a half times the depth of antennal flagellomere.

. In lateral view epandrium twice as high as wide, with a small anterior process, posteroventrally covered in multiple rows of short setulae with longer ones posteriorly along the margin, none of these particularly strong. Cerci not heavily sclerotised, upright and rounded apically, relatively small, less than half height of epandrium, with moderately long, well spaced setulae apically, some shorter ones on the ventral margin. One projecting tooth visible at the base of the cerci on one side, on the other side there are two teeth in this position. In ventral view surstyli with a vertical row of eight small black teeth extending down the inner surface below the posteriorly projecting tooth, the upper five in a distinct row, the lower three slightly more scattered. One thin sharp spine present on each side below the base of the cerci. Aedeagus in lateral view with a relatively wide basal portion from which arises the thin recurved apical part, a pair of thin finger-like processes arising from the basal part and extending below the upwardly curving apical portion.
