“Grapholitini sp. 3”: Brown et al. 2014: 350.

Diagnosis. Eucosmocydia deinbolliana is morphologically most similar to E. pancoviana , with both the forewing and the hindwing mostly dark brown. It can be distinguished from the latter by the orange rather than leaden gray scales in the distal half of the forewing, and by the more expanded patch of pale scales on the undersurface of the hindwing. Males are easily distinguished by the shape of the sclerite of segment 7 ( Fig. 30 ).

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. 4 ) length 4.5 mm (n = 1); 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, some in 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. 30 ) with small subquadrate sclerite at mid-venter. Male genitalia ( Fig. 21 ) 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. Unknown.

DNA barcodes. There is one sequence of this species in BOLD (BIN: ABW2619), and it suggests that E. deinbolliana is sister to E. mixographa .

Type. Holotype ♂, Kenya, Arabuko-Sokoke Forest , ca. 3°18.1′S. 39°59.14′E, 9 Jan 2000, A&M #418, R. Copeland, ICIPE/USAID, r.f. Deinbollia borbonica, USNM slide 153,700.

Distribution and biology. This species is described from the Arabuko-Sokoke Forest in Kenya. The holotype and only known specimen was reared from the fruit of Deinbollia borbonica Scheff. (Sapindaceae) .

Etymology. The specific epithet refers to the genus of the host plant, Deinbollia Schumach. & Thonn.
