Diagnosis. Eucosmocydia kirimiriana shares a small ocherous patch at the apex of the forewing with E. chlorobathra . However, in E. kirimiriana the forewing is more uniformly patterned throughout with dark brown and orange, except for a small, pale gray-ocherous patch at the base of the forewing costa in both sexes ( Fig. 14, 15 ), the latter of which serves to distinguish this species from its relatives. In the male genitalia, the cucullus is slightly longer with a less defined inner margin (more weakly and evenly rounded), and the phallus is slightly shorter than in related species.

Description. Male. Head. Scales of vertex and frons pale ocherous; 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 mostly pale brown, tegula brownish ocherous. Forewing ( Fig. 14 ) length 4.0–5.0 mm (n = 10); forewing with costa nearly straight, termen weakly concave beneath apex, convex in remainder; forewing pattern mottled throughout without distinct basal and distal halves; upperside ground color dark brown, with small patches and streaks of orange and dark gray scattered throughout, an ill-defined subbasal fascia formed by three or four dark brown to black spots, bordered by orange, angled slightly obliquely outward from hind margin ca. 0.3 distance from base to tornus, approaching a longer concolorous dash from costa near upper margin of discal cell; costal strigulae cream and gray, divisions black or brown, some in form of long blackish dashes; speculum near mid-termen with slender pale orange, crescent-shaped mark with two black dots. Fringe pale brown. Hindwing dark brown, paler in costa and subcostal regions. Fringe pale cream with brown basal line. Abdomen. Segment 7 ( Fig. 35 ) with narrow, small, slightly curved sclerite at mid-venter of anterior margin. Genitalia ( Fig. 27 ) with tegumen broad, ovoid, with sparse fine setae in dorso-posterior 0.6 representing fused socii; valva slender, with shallow, weakly curved concavity in basal 0.3 creating “neck,” cucullus representing distal 0.65 of valva; caulis short, broad; phallus evenly curved in distal 0.65, distinctly expanded at junction with caulis.

Female. Head and thorax. Essentially as described for male, except hindwing more uniformly brown, slightly paler in discal area, lacking secondary sex scales ( Fig. 15 ). Abdomen. Dark brown. Genitalia ( Fig. 44 ) with a pair of faint punctate regions at posterior margin of sternite 7; area surrounding ostium a shallow cup-shaped pocket; ductus bursae slender in posterior 0.5 (missing in preparation) broader in anterior 0.5 beginning at origin of ductus seminalis; corpus pear-shaped with two thorn-shaped signa of similar size.

DNA barcodes. There are six sequences of this species in BOLD (BIN: ABW2613), with an average distance of 0.14% among them and a 6.10% distance to its nearest neighbor, E. chlorobathra .

Distribution and biology. Eucosmocydia kirimiriana is known only from the Kirimiri Forest of Kenya where it was reared from Allophylus ferrugineus (Sapindaceae) .

Etymology. The specific epithet refers to the type locality of the Kirimiri Forest.
