Diagnosis.
The new species is superficially similar to
E. nairobiensis
Park
,
sp. nov.
, but it is larger than the latter; forewing with distinct blackish discal stigmata, termen less oblique and remarkably concave. The male genitalia can be distinguished by the more elongated cucullus; juxta smaller, with digitate median lobe on anterior margin, and aedeagus with a small, sclerotized, wedge-shaped cornutus.

Description.
Male and female (
Figs 5A, B
). Wingspan 14.0–15.0 mm.
Head
: vertex yellow white, furrowed centrally, with concolourous erect scales laterally. Antenna about 1.2 times longer than forewing; scape elongated, slightly dilated, yellowish-white throughout, without annulation. Second segment of labial palpus thickened, with more rough scales ventrally; yellowish-brown in basal half and yellowish-white beyond on outer surface; 3
rd
segment strongly upturned, slightly longer than 2
nd
segment, dark brown ventrally.
Thorax
: tegula yellowish-white dorsally, dark brown along anterior margin; thorax yellowish-white dorsally. Forewing ground colour yellowish-white, densely covered with bronze yellowish-brown scales; costa slightly arched beyond middle; apex produced; termen oblique, slightly concave; fringe yellowish-brown with narrow basal line; venation with R

Abdomen
: no spinous zones on dorsal surface.
Male genitalia
(
Figs 5C,D
):uncus basal lobes semi-ovate.Gnathos basal plate more or less elongated, triangularly produced on caudal margin. Coastal bar narrow, nearly not angulate medially. Valva broad basally, slightly angulate on ventral margin medially; cucullus elongated, narrowed in basal part; costa convex beyond half, densely setose along ventral margin; apex rounded; sacculus broadly developed, heavily sclerotized. Juxta shield-shaped, rather small, with narrow, membranous latero-caudal processes; slightly emarginated on caudal margin; anterior margin with digitate median lobe. Vinculum broadened apically, with a nearly flattened saccal zone. Aedeagus as long as valva, narrowly produced apically, with a pair of denticles before apex dorsally and a small, sclerotized, wedge-shaped cornutus.
Female genitalia
(
Figs 5E, F
): apophyses anteriores somewhat thick, about 2/3 the length of apophyses posteriores. Ostium bursae widened, irregularly margined. Antrum cup-shaped, slightly broadened posteriorly, about 1.5 times wider than long. Ductus bursae membranous, narrow in posterior 2/5 (about twice the length of the antrum), anterior 3/5 broadened, as wide as corpus bursae, not well demarcated from corpus bursae; ductus seminalis arising from the broadened part. Corpus bursae large, ovate; signum broad, airflight-shaped, with weakly sclerotized quadrate upper plate and smaller lower plate.
Distribution.
Kenya
(Central, Rift Valley).
Etymology.
The species name is derived from the Latin, -
campana
(= bell), referring to the bell-shaped antrum of the female genitalia.
