Fig. 14.

DIAGNOSIS. Very small, black species with mostly orange-red legs. Wings slightly infuscate, iridescent, uniformly covered by microtrichia.

The species is close to A. javana de Meijere, 1914 and A. indiana Joseph & Parui, 1987 . It can be separated from A. javana by the marginal cell closed with short stalk and abdominal tergites I–III with fine long hair (marginal cell closed with long stalk and only abdominal tergite II with fine long hair in A. javana ); from A. indiana by the end vein of discal cell before the fourth posterior cell, and tergites II–VIII with bristles (end vein of discal cell beyond the fourth posterior cell, and tergites II–VIII without bristles in A. indiana ).

ETYMOLOGY. The species epithet minima (adj., Latin) means very small and refers to the size of the species.
