Ambadra gracilis Holloway sp. n.

♂ 15mm. The size of this species is as in the suriga Schaus complex (see taxonomic notes on A. melanostriga), but the forewings are distinctly narrower, lack a pale discal mark and have no particularly dark longitudinal streaks in the marginal zone. There are three darker patches set obliquely and on a slightly obtuse angle in the antemedial position. The male genitalia have rather narrow valves compared to the species referred to suriga in Borneo. The uncus and socii are closer to, but shorter than, those of modesta Schintlmeister (S & P, 2007; this is the species from Peninsular Malaysia identified as stigmatica Gaede by Holloway (1982)), as is the strong curvature of the aedeagus, though this is distinctly upturned (straight in modesta) and bifid at the apex in gracilis. The valves are narrower, however, and the vinculum is distally thickened. The sternite has longer apodemes, and its two central processes are more widely separated.

Taxonomic note

A. stigmatica Gaede (India) is also related (holotype male genitalia illustrated in Fig 97), and, with modesta and gracilis, completes an allopatric array of three species.
