Prothoracic spiracle yellow. Prosternum bare. Proepisternum with 2-3 hair-like setulae on lower part. Antepronotum with several spinule-like setulae on each side. Postpronotal lobe with one short inclinate ppn and additional shorter seta anteriorly. Mesonotum with one short thin presutural sa, one long npl, one short pa (sometimes with 1-2 additional setulae), four sc (apicals short, laterals minute); acr absent; dc uniserial, 6-7 in row, situated outside black median vitta, hair-like, minute (except 1-2 prsc). Laterotergite with several black setulae of different lengths. Legs yellowish to brownish yellow, only tarsomere 5 dark brown; lacking prominent bristles (except circlets of short subapical setae on tibiae). Wing nearly hyaline; brownish yellow stigma long, narrow; veins dark brown; basal costal bristle black, very short. Calypter yellowish, blackish fringed. Halter yellow.</paragraph>
