“Grapholitini sp. 8”: Brown et al. 2014: 350.

Diagnosis. The forewing of the female of E. chlorobathra is dark and somewhat mottled throughout as in E. kirimiriana , but it lacks the small ocherous patch at the base of the forewing characteristic of the latter. In the male genitalia of E. chlorobathra ( Fig. 26 ), the valvae are considerably broader than in other species of the genus, and the distal 0.2 of the phallus is slightly upturned.

Redescription. Male. Head. Scales of vertex and frons pale reddish 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 brown, tegula slightly paler. Forewing length 4.0 mm (n = 3); forewing with costa weakly curved throughout, termen weakly concave beneath apex, convex in remainder; forewing pattern mottled throughout without, but distinctly paler in distal 0.5; upperside ground color dark brown, with small patches and streaks of gray scattered throughout, more dense in basal 0.33; costal strigulae cream and gray, divisions black or brown, some in forming blackish dashes; speculum near mid-termen with slender pale orange, crescent-shaped mark with one black dot. Forewing underside tan with alternating rows of black and cream scales in basal 0.75, except three larger, patches of black scales, one irregular patch near base of wing at costal edge of discal cell, one elongate subrectangular patch arising near base of wing extending along CuP, and one irregular patch just beyond terminal of latter patch. Fringe pale brown. Hindwing dark brown, paler in costa and subcostal regions. Fringe pale cream with brown basal line. Hind tibia with pencil of whitish hair-scales. Abdomen. Sternite 7 with narrow crescent-shaped sclerite at mid-venter of anterior margin ( Fig. 34 ). Genitalia ( Fig. 26 ) with tegumen broad, rounded, with sparse fine setae in dorso-posterior 0.6 representing fused socii; valva with costa upcurved n 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 lacking black scales on upperside of hindwing and underside of forewing ( Fig. 13 ). Abdomen. Genitalia ( Fig. 40, 41 ) lacking paired setose patches at posterior margin of sternite 7; area posterad of ostium with wide, V-shaped pocket, vertex of pocket with antrum undifferentiated, more or less confluent with ductus bursae; ductus bursae slender in posterior 0.6 abruptly broadening in anterior 0.4 at origin of ductus seminalis; posterior 0.2 of ductus bursae angled twice, then relatively straight; corpus bursae round, finely punctate throughout, with two thorn-shaped signa of similar size.

DNA barcodes. There are six sequences of this species, four from Kenya, and two from South Africa, in BOLD (BIN: ACI4940), with an average distance of 0.27% among them, and a 5.78% distance to their nearest neighbor, E. kirimiriana .

Distribution and biology. Eucosmocydia chlorobathra is known from the Seychelles, Kenya, Malawi, Tanzania, and South Africa. In Kenya it was reared from Allophylus pervillei and A. rubifolius (Sapindaceae) . In addition to the material listed above, sequence data from two specimens in BOLD (SAFRA3874-18 from Mpumalanga, Kruger National Park, Marula South, Skukuza, 24 Nov 2017 and KMPOU121-19 from Limpopo, Kruger National Park, Nxantseni North, Sangoni, 21 Feb 2019) place them in the same BIN (ACI4940) as those from Kenya. However, the latter two specimens were not examined; they were collected in Malaise traps, and there are no images of them in BOLD.
