( Figs 12a–b ) Prasodryas opalina Ghesquière, 1940 — Revue de Zoologie et Botanique Africaines , 34 (1), 106. Material examined. 1 ex (abdomen missing), [ DR Congo ] Musée du Congo , Eala , vii.1937 , J. Ghesquière | R . Det. L 4408 | Prasodryas opalescens Ghesq. 1940 ( RMCA ) . Remarks. Prasodryas opalina was described based on the female holotype collected in “Eala, vii.1938 ” (Ghesquière 1940). The type specimen was not traced in the collection of RMCA. However, a specimen without abdomen labelled “Eala, vii.1937 ” “ Prasodryas opalescens Ghesq. 1940 ” (nomen nudum) was found in a separate unit with the bottom label “ Dichomeris opalina (Ghesquière, 1940) ”. This specimen matches the original description of P. opalina , and may represent a type of this species. The external characters (segment 2 of the labial palpus with a brush of long scales beneath) justify the assignment of P. opalina to the genus Dichomeris , and herewith we transfer this species to the latter genus. The species can be recognized by the produced apex of the forewing that is unique among species of Dichomeris . Distribution. DR Congo : Équateur Province .
