Genus Apatidelia Mosely, 1942

Apatidelia Mosely, 1942: 343

(type species: Apatidelia martynovi Mosely, 1942 , by original designation).

Diagnosis

Adult

Body size moderately small, length about 5.0–9.0 mm; body color dark-brown. Cephalic setal warts similar to those of Apatania , with a pair of lateral ocelli. Fore wings transparent, with a patch of dense hairs near the apex of vein Sc; vein R with a row of close, short, black hairs from the apex to the sub-base ( Mosely 1942); FI–III and FV presented in both fore and hind wings; discoidal cells in the fore wings are closed but are open in the hind wings. Spurs 1, 2, 4. Abdominal sternum V with a lateral process on each side in male, by which males are easily separated from any other genus of the tribe Apataniini . However, due to the absence of such structures, females of the genus must be identified by a short apical vulvar lobe of sternum VIII and a roof-shaped, slightly sclerotized segment X. The vulvar lobes of sternum VIII in female Apatania Kolenati, 1848 are usually slender, thumb-like or slender, rectangular.
