Antennae of males usually reaching posterior margin of pronotum or beyond, antennae of females shorter, not reaching posterior margin of pronotum. Antennal funicle slender, then antennal club 3-segmented (most species) or 4-segmented, or antennomeres continuously extended. Dorsal transverse carina of pronotum distinct and antebasal. Medium- or large-sized species, from 6 mm ( D. arofaniana Trýzna & Baňař 2022 , D. lusti Trýzna, Blažej & Rakotonirina sp. nov. or small specimens of D. rubricollis (Fairmaire, 1893)) to more than 18 mm ( D. olivacea Waterhouse, 1877 ).

Male and female genitalia conspicuously small compared to overall size of body (see Discussion in Trýzna & Baňař 2022). Female genitalia: ovipositor short and wide, hemisternites strikingly short and delicate, unarmed, without distinct toothed plates, with only numerous setae or small preapical stylus. Lateral and median rods very short, median rod reaching about half of the length of lateral rod. Transverse bar invisible. Male genitalia more diversely shaped.
