“Grapholitini sp. 22”: Brown et al. 2014: 351.

Diagnosis. In E. pancoviana both the forewing and hindwing are darker than in most other members of the genus, with more extensive leaden gray scaling in the distal half of the forewing. In the hindwing of the male, the costa is white and there is a narrow cream streak in the subanal region, which serve to distinguish it from other members of the group. The male genitalia are most similar to those of E. kirimiriana with the basal 0.5 of the valva narrower than the distal, upcurved 0.5 (cucullus).

Description. Male. Head. Scales of vertex and frons grayish brown; labial palpus weakly upturned, length approximately 1.2 times diameter of compound eye, third segment exposed, scales of labial palpus and basal flagellomeres of antenna concolorous with vertex. Thorax. Nota and tegula brown, frosted with cream-tipped scales. Forewing (Fig. 10) length 4.5–5.0 mm (n = 5); forewing with costa weakly curved throughout, termen with shallow notch immediately below apex, rounded convex in remainder; upperside ground color dark brown, basal 0.33 with faint, irregular streaks of striae of cream scales; an irregular, dark brown, oblique line from basal 0.33 of hind margin bordering inner region; distal 0.66 of forewing with more complex pattern of irregular brown and leaden gray blotches, and orange striae; costal strigulae cream and gray, divisions black or brown, in some forming blackish dashes; speculum near mid-termen with extremely narrow, pale orange, crescent-shaped mark bordering wider leaden crescent, with three distinct black dots. Fringe pale brown. Hindwing dark brown, paler in costa and subcostal regions. Fringe pale cream with brown basal line. Abdomen. Brown with narrow cream band at distal margin of each segment. Segment 7 (Fig. 33) with expanded sclerite at mid-venter, rounded at anterior margin, with weakly subtriangular, median pointed process posteriorly. Male genitalia (Fig. 25) with tegumen broad, rounded, with sparse fine setae in dorso-posterior 0.6 representing fused socii; valva with costa upcurved in distal 0.7, venter with shallow, weakly curved concavity in basal 0.3 creating ill-defined “neck,” cucullus representing distal 0.5 of valva, rather broad; caulis long, rodlike, attached to phallus subbasally; phallus downcurved at ca. 0.6 distance from phallobase to apex, then weakly upcurved in distal 0.2.

Female. Head and thorax. Essentially as described for male, except hindwing uniformly brown (Fig. 11). Abdomen. Brown with narrow, ill-defined, pale line at distal edge of each segment. Genitalia (Fig. 43) with membranous, cup-shaped part of sterigma short; post-ostial sterigma broad, weakly sclerotized; sclerite of colliculum short, weak; ductus bursae slender to before middle where ductus seminalis originates; corpus bursae rounded, a pair of small, thorn-shaped signa.

DNA barcodes. There are two identical sequences of this species in BOLD (BIN: ACH7952), and E. pancoviana appears to be sister to E. deinbolliana.

Types. Holotype ♂, Kenya, Coast Province, Kasigau Forest, -3.82039, 38.66122, 1283 m, CHIESA 334, r.f. Pancovia golungensis, 14 Oct 2012, R. Copeland. Paratypes (11♂, 15♀). Kenya: Same data as holotype.

Distribution and biology. This species is known from a long series of specimens from Kasigau Forest, Kenya, where it was reared from Pancovia golungensis (Hiern) Exell & Mendonça (Sapindaceae).

Etymology. The specific epithet refers to the genus of the host plant, Pancovia Willd.
