About Nisia nervosa (Motschulsky, 1863)
Adults of Nisia nervosa have a total body length (including forewings) that ranges from 3.5 to 4.2 mm in males, and from 4 to 4.5 mm in females. Forewing length measures 3 to 3.6 mm for males, and 3.5 to 4 mm for females. The head is short, and the eyes are distinctly narrower than the pronotum. The vertex has two widely separated triangular posterolateral areolets. The frons is longer than it is wide at its broadest point, and is longer than the clypeus along the midline. For males, when viewed from the dorsal side, the anal segment has nearly parallel lateral margins, each bearing a finger-like lateroapical process. The aedeagus is short, broad, flattened, and strongly deflexed at its apex. The genital styles curve at an angle around their midpoint. Nisia nervosa is widely distributed across South Asia, East Asia, Southeast Asia, the Middle East (including the United Arab Emirates and Israel), Iran, and Africa.
