Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Rincón Rain Forest, Río Francia, 410 m, 25.i.2009, R. Franco and H. Cambronero, GenBank accession code GU675011 ( USNM).

Paratypes (28♂, 15♀). See Appendix 1.

Diagnosis. Chlamydastis elenaulateae is most similar to C. paulhansoni . It can be distinguished by its shorter gnathos and broader uncus with a more deeply emarginated apex. Chlamydastis elenaulateae can be distinguished from the related C. gladysrojasae by the larger, more rectangular signum (smaller and more rounded in C. gladysrojasae ).

Description. MALE ( Fig. 21 ). Head. Frons and vertex brownish, collar light brown; labial palpus with first and second segments brownish, third segment paler; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Base of tegula and anterior margin of prothorax brownish, mesothorax gray, metathorax gray with a semicircular blotch of green scales on posterior end. FW length 10.0– 10.4 mm; FW brown with faint olive green overscaling on most of wing, browner in costal 0.5, with faint black lines along veins, paler in lower 0.5, without lines along veins; small irregular green blotches near premedial line. Abdomen. Dorsum light brown, venter darker with paired whitish spots on central segments. Genitalia ( Fig. 68 ) with uncus slender, ca. 0.7 times length of valva, with deeply emarginated apex; gnathos short; valva ovate, with rounded apex, strongly veined, with dense cluster of specialized setae near mid-costa; sacculus short, subrectangular, with a free distal end, confined to basal 0.15 of valva; phallus curved throughout, with small hook distally and a slender sclerite in vesica.

FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 12.7–12.9 mm. Abdomen. Genitalia ( Fig. 105 ) with papillae anales with rounded outer margin in posterior 0.5, together weakly cordate, each papilla with a distinct line of sclerotization in basal 0.5; ductus bursae slender, weakly broadened anteriorly to ill-defined junction with corpus bursae; corpus bursae subrectangular, with distinct, more-or-less parallel longitudinal creases or lines, signum subrectangular, rounded at each end.

DNA barcodes. The 79 barcode sequences of C. elenaulateae form a uniform BIN (BOLD:AAA1073) with an average distance of 0.04% among sequences and a distance of 3.19% to its nearest neighbor, C. paulhansoni .

Distribution. Chlamydastis elenaulateae has been collected in ACG from 140 to 675 m in the rain forest and rain forest-dry rain forest lowland intergrade, and in ACC Turrialba at 630 m.

Biology. Chlamydastis elenaulateae has been reared from caterpillars feeding on Chrysophyllum brenesii Cronquist (n = 57), Chrysophyllum cainito L. (n = 9), Pouteria reticulata (Engl.) Eyma (n = 20), and Sideroxylon capiri (A. DC.) Pittier (n = 4) (all Sapotaceae ) ( Table 1).

Immature stages ( Fig. 129 ). Head, T1, T2, and T3 bright red, T2 with broad yellow dorso-posterior band; abdominal segments bright red, with yellow dorso-posterior bands on A1, A2, A4, A5 and A8; A9 and A10 translucent reddish orange.

Etymology. Chlamydastis elenaulateae is named in honor of Elena Ulate in recognition of her technical support of the national biodiversity inventory of Costa Rica.
