Frons greyish brown; vertex and ocellar triangle dark brown, lower postocciput brown, gena lightly pruinescent. Ocellar setae longest among cranial setae; occiput with 3–4 pairs of setae posterior to ocellar triangle; postocular with row of short setae along margin of eye, upper 3–4 setae dark, stouter than lower setae. Arista lost in type series. Palpus pointed apically, ca. one-fourth height of eye.
Pleura grey with pale grey-blue pruinescence; scutum brown with pale, somewhat bluish lateral margins and median paler stripe extending full length of scutum; postpronotal lobe and postalar callus paler brown; faint dark vitta along inner edge of dc in dorsal view.
