Redescription.

Male ( Figs 5E, 5F , 6E, 6F ): Head, thorax and abdomen same to the nominate subspecies. Wings: FW (length 36-39 mm, mean: 37.8 mm, n=6) with an elongated apical part, and gently convex outer margin; most of wing surface black; costa from base to apex dusted with dark blue, suffusing a black mid-discal cell black patch; pine green area from wing base to tornus, covering most of Cu2-1A and half of Cu1-Cu2; a large, elongated lawn green subapical patch, extending widely from subcosta costa to vein Cu1, with the basal limit marked by an incision along vein M3, and a diffused outer limit, not reaching outer margin; fringes grey and black. HWD oval with a gently scalloped outer margin; pine green grey except for the row of submarginal black, roughly rectangular patches, with a strong blue sheen gradually narrowing from roughly 4 mm at apex to cell Cu1-Cu2; fringes grey and black. FWV pine green, with a delicate golden overcast in subapical area; basal to mid-cell area pink; a series of black patches, a rounded postbasal spot, a wide mid cell bar, a similar bar along discal cell distal margin, four rectangular and one elongated patches in postdiscal area, a half-moon shaped patch in basal area of cell Cu1-Cu2, and a series of submarginal patches, five smaller from costa to cell M3-Cu1 and two larger, roughly oval, in Cu1-Cu2 and Cu2-1-2A. HWV golden yellow dusted with pine green in median area, with an elongated basal pink patch extending from costal margin to Rs to one-third costa, edged with black; six or seven median spots, four of which in discal cell, the one along costal margin considerably larger than the remainder, and a row of eight large, roughly oval black submarginal patches; marginal area darker pine green and black. Male genitalia ( Fig. 11C ): Tegumen same length as uncus, with a flat dorsal surface; uncus stout, aligned with the dorsal surface of shoulder, tip sharp, both tegumen and uncus longer than in the nominate subspecies; gnathos long, same length as uncus; pedunculus prominent; saccus flattened in lateral view; valvae with a smooth dorsal surface and blunt apex; aedeagus as long as valvae tubular and straight, with a sharp distal extremity, slightly longer than in the nominate subspecies, and prominent cornuti.

Female ( Figs 7E, 7F ): Sexual dimorphism slight except for the larger size of the female (FW length: 40-41 mm, mean: 40.5 mm, n=2). Female genitalia: not examined.

Range.

Known distribution is limited to the Tai National Park in western Ivory Coast.
