Posterior half of frons shining black, parallel sided, about four times the diameter of the anterior ocellus and as wide or wider than the length of the longest hairs on the ocellar tubercle, a few tiny, proclinate hairs close to eyes forward of anterior ocellus. Anterior half of frons widening rather abruptly, more than lateral third each side covered in dense whitish dust obscuring ground colour, central shining black strip narrower than dusted areas. Third antennal segment sometimes shorter. Anal lobe broader, margin more convex, almost as broad as the anal cell. Abdomen conical tapering to a rounded point, apical sternite evenly convex, wider than long, apical emargination small and shallow, in dry specimen a square spot of pale dust discernable apicomedially.
