Cechenena mirabilis
Immediately distinguishable from all other species of Cechenena by the blue-green ground colour of the forewing upperside overlaid by a dark green basal and medial pattern. Tegulae with a long pale pink apical fringe on the outer margin. Thorax upperside uniform dark green. Abdomen without dorsal lines. Outer row of spines of forebasitarsus double at base; outer midtibial spur shorter than in Cechenena aegrota; spines of midtarsal comb stout and quite short; those of the hindtarsal comb very little elongated. Forewing upperside ground colour blue-green, with a dark green basal area and a vaguely H-shaped patch just distal to the small and indistinct pale discal spot. Antennae apically clubbed.
Male genitalia: Uncus similar to Rhagastis velata. Gnathos similar to Rhagastis velata. Valve with more stridulatory scales than in Rhagastis velata. Harpe similar to Rhagastis castor but much longer. Phallus similar to Rhagastis lunata but with the left apical process short and with few teeth, and a rather a long right process.
