Diagnosis. Adult: Antenna longer than prothorax; eye considerably large. Length of pronotum varied at least as long as or longer than wide. Wings very narrow, both margins almost parallel; Cua fork arising before Rs in forewing; Cup+A 1 and Cua 2 run diagonally to hind margin in forewing; hindwing with one cross-vein in front of origin of Rs. Femur longer than tibia. Tibia with upstanding long stiff bristles. Basitarsus remarkably long, and tarsal segment 5 as long as or slightly longer than tarsal segment 1. Tibial spurs almost straight, elongated at least as long as or longer than segment 1. Claws simple, and long. Sexual dimorphism present. Male abdomen very long and extending beyond wings in resting position. Male abdomen longer than that of female, which approximately as long as hindwing. Male ectoproct with longer and shorter processus or postventral lobe. Female gonocoxites 8 (=posterior gonapophysis) significantly longer than anterior gonapophysis. Digging setae on ectoproct and gonocoxites 9 (=lateral gonapophysis) rather stout, strongly developed.

Larva: Based on Badano & Pantaleoni (2014), dorsal surface of head and pronotum covered by white scalelike setae, mesothorax with pedunculated or sub-peduncolated setiferous processes, VIII abdominal sternite with prominent odontoid processes, IX abdominal sternite wider than long and without fossoria.

Distribution. Africa, Madagascar, South Europe, West and Central Asia.
