Polyommatus is a large genus of blue butterflies found throughout the Old World.
Characters (from Bingham 1907): Fore wing with costa very slightly arched, nearly straight; apex well-marked but not acute; termen convex; tornus obtuse; dorsum straight; cell not quite half length of wing; veins 6 and 7 closely approximate almost from a point; middle and lower discocellulars attenuate; vein 8 absent, vein 9 from middle of vein 7, veins 10 and 11 from apical half of subcostal; vein 12 bent towards vein 1l, very close, touching but not anastomosed; vein 12 long, terminates on costa opposite apex of cell. Hind wing with costa slightly arched; apex rounded; termen rather straight especially in the female, in the male slightly convex; tornus well-marked, angulate, dorsum rather long; cell very short, not nearly half length of wing; middle and lower discocellulars attenuate; veins 3 and 4 from lower apex of cell, vein 7 from only a little before upper apex of cell; vein 8 strongly arched at base, terminating on costal margin well before apex of wing. Antenna short, not quite half length of fore wing, club long and gradual, pointed at apex; eyes hairy; palpi porrect or subporrect, fringed anteriorly; third joint rather short, bare, aciculate; body comparatively robust. Male with sex-mark: fore and hind wings thickly overlaid with hair-like scales that give a frosted appearance to the upperside; underside of fore wing with a patch of specialized scales at bases of interspaces 2 and 3.
