Material examined: PERU: HOLOTYPE male: Cuzco, P. N. Manu, Acjanaco, 3200–3450 m, 05.VII.1991, M. Medina leg., red, rectangular label saying: Holotype, MUSM; PARATYPES (3 males): 2 males: same data as HT but 07.VII.1991, MUSM; 1 male: Cuzco, Abra Acjanaco vers Pillcopata km 10, 3000–3100 m, 24.II.2005, P. Boyer leg., PBF.

Description: MALE (Figs. 4F): Head, thorax and abdomen not differing from nominate subspecies. FW length 27 mm. FWD and HWD dark brown, a shade darker than in nominate subspecies; FWV differs immediately from that of nominate subspecies in totally lacking any trace of red suffusion in wide, light brown postmedian patch. HWV ground colour lighter brown with an olive shade, otherwise similar to nominate. Genitalia (Fig. 11B): Uncus longer than in nominate; gnathos and saccus similar; valvae also longer than in nominate with a wider apical half, apical spine-like process slightly shorter; aedeagus longer than in nominate, otherwise similar.

FEMALE: Unknown.

Etymology: This subspecies is dedicated to Mirian Medina Hay-Roe, Peruvian entomologist and first collector of this taxon.

Remarks: D. dognini mirianae is known so far exclusively from the upper valley of Kosñipata, but its range is most probably much wider. The parallel and more southerly valleys of Marcapata and Ollachea have barely been sampled for butterflies.
