Diagnosis. The forewing length is 10.0–13.0 mm in males and 11.0–13.5 mm in females. The new species (Figs 12–16) is reminiscent of G. lydiae sp. n. (Figs 8–11), but can be distinguished by its narrower and paler yellow costal stripe. The male genital capsule of the new species (Figs 23, 24) differs from those of its congeners (Figs 17–22) in the wider intervincular area, the more convex costa and the thinner distal saccular process. Additionally, compared to G. lydiae sp. n. (Figs 21, 22), the valva of G. smithi sp. n. is distally narrower and the distal saccular process is shorter. The phallus of the new species is thicker than those of G. proleuca and G. lydiae sp. n. and has a shorter coecum. The vesica of G. smithi sp. n. is longer and markedly broader than those of its congeners with two additional lateral diverticula covered in fine spinulose scobination (whereas the vesica of G. proleuca and G. lydiae sp. n. is granulated). The cornutus of the new species is basally thinner than in G. proleuca (Figs 17, 18) and G. bettoni sp. n. (Figs 19, 20) and somewhat longer and thicker compared to that of G. lydiae sp. n. (Figs 21, 22). The female genitalia of G. smithi sp. n. (Fig. 29) are similar to those of G. lydiae sp. n. (Fig. 28) but distinguished by the somewhat broader antrum, the slightly narrower and longer anterior sclerotised section of the ductus bursae, and the shorter and narrower posterior diverticulum of the corpus bursae. Distribution. Known from southern Mozambique and South Africa (provinces of KwaZulu-Natal and Eastern Cape) (Fig. 31). Etymology. The new species is dedicated to Mr Richard Smith, Chairman of the Board of Trustees, African Natural History Research Trust, who, through organising and undertaking numerous entomological expeditions to Sub-Saharan Africa has enabled the discovery of numerous species new to science.
