reriiform spot obsolescent, defined with some blackish spots at outer edge. Medial area consists of a darker patch below cell containing stigma and a shiny field at inner margin. Stigma small, silvery, bilobate or finely disjunct. Postmedial line double, slightly sinuous, strongly angled inwards between veins anl-cu2, filled with rosy-whitish. Terminal field suffused with greyish, very shiny, subterminal line sinuous, termen with a dark, oblique shadow running from apex to vein m2. Terminal line fine, whitish with blackish triangles and a conspicuous rosy line from apex to vein cu2. Cilia dark violaceous-brown with a black spot at vein m3. Hind wing light ochreous, marginal suffusion wide, brown; veins covered rith dark scales. Transversal line and cellular lunule well-discernible, cilia light ochreoue, spotted with brown. Underside of wings ochreous-grey, inner area of fore wing and a wide stripe between postmedial and subterminal lines suffused with dark grey-brown. Male genitalia (Figs 11-16, 24-25): uncus long, distally slightly dilated, tegumen gracile and high, fultura inferior deltoidal, vinculum moderately long. Saccus membranous, with a pair of small, ventral flaps. Valvae elongate, costal margin finely S-shaped, cucullus slightly dilated and rounded, corona nearly entirely reduced. Clavus long, bar-shaped, harpe usually short and apically dilated, apex of it more or less rounded. Ventral margin of valva bears a row of strong, flattened, easily removable scales. Dorsal surface with two bundles of specially modified, dark brown or blackish scales. Aedeagus long, pistol-shaped with a strongly sclerotized ribbon on ventral axis. Vesica tubular, membranous, with a pair of long and slender, granulöse laminae running from distal edge of aedeagus towards to basal third of vesica; basal area contains a hyaline sac inside. Distal part of vesica more or less arcuate and bears two or three cornuti, largest of them terminal one. The new species is very close to C. (A. ) agnata fStaudinger, 1892), and, as it has not an unambiguous distinctive feature in the male genitalia, - although the specimens of these sibling-species are externally well-separable - , the specific identity of microptera had not been stated and a part of the specimens of the type series was published as agnata (Ronkay, 1986). The studies on the new material and the previously unknown female are pointed out that microptera is a distinct species having statistical differences also in the configuration of the male genitalia. The characteristic features of the two allied species are as follows: microptera 1. fore wing shorter, wingspan smaller with average 27 mm 2. ground colour of fore wings darker and more unicolorous 3. hind wing with light ochreous inner area, transversal line and cellular lunule visible 4. underside of wings lighter, ochreous, terminal light stripes more conspicuous 5. abdomen with ochreous hairs on first three segments 6. valvae less arcuate with narrower cucullus 7. harpe usually short and apically dilated 8. vesica shorter, field of cornuti placed more near to distal end of aedeagus 9. sclerotized part of ductus essentially shorter 10. sclerotization of ductus bursae not reaches anterior angle of ductus a

nata 1. fore wing more elongate, wingspan larger (31.5 mm for the material from Vietnam) 2. ground colour lighter, shine more goldenbronze, with more intensive dark irroration in medial and marginal areas 3. hind wing nearly uniformly dark brown, cellular lunule and especially transversal line obsolescent or deleted, 4. underside of wings suffused with brownish scales and the lighter areas less extensive and greyish-brown, 5. abdomen with grey-brown hairs only 6. valvae more arcuate (costal margin!), cucullus wider, more curved 7. harpe longer and more gracile 8. vesica longer, field of cornuti placed significantly more remote from distal end of aedeagus 9. ductus bursae longer 10. sclerotization of ductus bursae extends into anterior angle forming a hook
