Eoophyla nandinalis (Hampson, 1906) comb. n.

Argyractis nandinalis Hampson, 1906: 383.

Type locality: Kenya: Eb Urru (now Eburu)

Imago (Fig. 55): Wingspan 18–26mm. Head whitish ochreous, darker centrally; labial palpus upturned, whitish, segments 1 and 2 with a fuscous line laterally; antenna pale fuscous, scape whitish. Thorax ochreous; tegulae whitish. Forewing ground colour whitish; costa fusous in basal half; a weak subbasal fuscous fascia; an oblique yellow antemedian fascia in dorsal half of wing; a slender angled fuscous median fascia; a yellow crescent in disc almost connected to preapical costal strigula, preceded by a fuscous costal strigula; terminal band yellow, some black dashes along termen; oblique silver grey tornal spot; terminal cilia pale fuscous. Hindwing white; an obscure central fuscous subbasal spot; irregular yellow median fascia, some fuscous scales beyond this; double submarginal line; four terminal eyespots, first very small, 2 and 3 large, each with a pair of silver spots 2/3 up each side, termen basally yellow; inner half of cilia fuscous.

Male genitalia (Fig. 117): Uncus tapered to a blunt point; gnathos 3/5 uncus, tip curved slightly towards uncus, bearing spines; valva gradually widening, then reducing in width then forming a right angle at apex, shortly before this arises a single strong seta; saccus rounded; juxta set with four stout spines on either side; aedeagus waisted, apical area surrounded by sclerotised spiny area, a few weakly defined cornuti. Sternum 8 with a pair of bluntly pointed projections separated by a deep V-shaped incision.

Female genitalia (Fig. 171): Ostium wide, cup-shaped; ductus long and broad becoming wrinkled before sclerotised colliculum; corpus bursae at first narrow then widening into a sock-shaped sack, a double sclerotised band along the right hand side; ostium and ductus 5/8 length of corpus bursae.

Tympanal organs: Venulae straight and parallel, tympani as rounded squares.

Diagnosis: A comparatively large species, distinguished by the double subterminal line of the hindwing; in the male genitalia the shape of sternum 8 described above is unique.

Biology: Unknown; in rivers; adults continuously brooded, recorded in every month except June.

Distribution: D.R. Congo; Kenya, in the highlands, chiefly rivers arising from the Mau Forest on the West side of the Rift Valley.
