Diagnosis

Body slim. head equally wide as pronotum, rounded anteriorly, vertex long, its profile regularly curving into flat, elongated face. Forewing with 3rd apical cell stalked. Hindwing with very small area bordered by re-emerging AA and AP' veins. Genital capsule flattened dorsoventrally, dorsal bridge long. Segment 10 long and narrow with slightly sclerotised eusternite. Segment 11 long and narrow. In pygofer all parts very well consolidated, free lobe of CX very short; subgenital plate solid, exceeding pygofer; paramere longer than pygofer. Pygofer enlarged. Acrotergite 9 distinct, bearing apodemes ventrally and apophyses dorsally, remaining parts well consolidated and can be vaguely located based on connections and sensillae only; acrotergite 10 in form of a narrow sclerotisation mostly on dorsal extreme of free lobe of CX; sensory structures restricted to pits, one campaniform sensilla and short rigid microsetae at the margin of the free lobe. Subgenital plate lamellate narrowing apicad with large basal lobe in laterodorsal region and well developed subbasal articulation with paramere; setosity specialised. Plates freely articulated with sternite 9 which is narrowed mesally. Paramere with triangularly broadened central part, hooked apically with distinct dentifer and a few small setae subapically. Connective small, fused to penis. Penis with basal section subdivided, strongly fused to eusternite 10 caudally, joining extensions of segment 10 before its caudal extreme and sending off cephalad elongated apodemes that are situated on both sides of the penis stem; first section hard to detect in the type species but it must be situated between bases of penis apodemes and base of the penis stem and, most probably, participates in penis stem because in D. picturata (Evans) there are appendages at the penis stem that usually originate mostly from the first section. Segment 10 with not easily identifiable mesocoxite, sending mesally very short (knob-like in the type species) unpigmented extensions joining basal section of penis laterodorsally and laterally very short processes; eusternite well pigmented only on its caudal margin laterally with pigmentation and sclerotisation fading mesad and cephalad. Abdominal apodemes short with broad bases, diverging apically (Dworakowska 1995).
