Diagnosis. The forewing length is 11.5–13.0 mm in males and 12.0–14.5 mm in females. The species is characterized by the relatively narrow forewing with a thin pale yellow costal stripe ( Figs 1–3 View FIGURES 1–8 ). The male genitalia of the species ( Figs 17, 18 View FIGURES 17–20 ) are most similar to those of G. bettoni sp. n. ( Figs 19, 20 View FIGURES 17–20 ), the distinctive features between the two taxa are discussed in the diagnosis of the latter species. Compared to G. lydiae sp. n. ( Figs 21, 22 View FIGURES 21–24 ) and G. smithi sp. n. ( Figs 23, 24 View FIGURES 21–24 ), the male genital capsule of G. proleuca has a basally wider valva. In the vesica, the lateral diverticulum is very short and the cornutus is markedly more robust than in G. lydiae sp. n. and G. smithi sp. n. The female genitalia of G. proleuca ( Fig. 25 View FIGURES 25–29 ) are similar to those of G. proleucodes ( Fig. 26 View FIGURES 25–29 ) and G. bettoni sp. n. ( Fig. 27 View FIGURES 25–29 ), the comparisons are provided below under the diagnoses of the species.

Distribution. Known from Ghana ( Hampson 1914), Ivory Coast, Liberia and Guinea (new records) ( Fig. 31 View FIGURE 31 ).
