Holotype. Male, Costa Rica, Alajuela, ACG, Sector Rainforest, Estación Leiva , 454 m, 19.viii.2009, F. Quesada and R. Franco, 09-SRNP-107481, GenBank accession code HM407883 ( USNM).

Paratypes (19♂, 1♀). See Appendix 1.

Diagnosis. The forewing pattern of C. bernardoespinozai is somewhat irregularly checkered and unlike that of other species in this group. The male genitalia are most similar to those of C. bobandersoni , but those of C. bernardoespinozai have a larger, broader uncus; a less undulate lower ventral edge of the sacculus; a less pointed distal end of the sacculus; and a much longer distal sclerite of the phallus.

Description. MALE ( Fig. 14 ). Head. Frons, vertex and collar whitish; labial palpus cream with yellow and brown scales intermixed forming a lateral band along first segment and basal 0.75 of second segment; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Dorsum and tegula whitish intermixed with greenish scales, pro- and metathorax with narrow greenish band. FW length 9.1–10.5 mm; FW ground color pale olive with traces of gray green overscaling and irregular spots and streaks of dark brown and brownish olive; three dark, ill-defined blotches along costa at ca. 0.25, 0.50, and 0.75 distance from base to apex; a short black dash through middle of discal cell ending in a small pale spot; greenish olive band from outer margin of pale spot at end of discal cell to hind margin just before tornus. Abdomen. Externally pale brown. Genitalia ( Fig. 61 ) with uncus large, broad; anterior margin at intersection of lateral halves of tegumen forming a rounded arch; gnathos absent; dorsal part of valva ovate, evenly attenuate apically, with dense patch of specialized setae along middle of costa, irregularly triangular basal part representing sacculus ca. 0.5 length of valva, with weakly developed haripencil; lateral processes of juxta as long as their bases; two semicircular sclerotized lines laterally at base of juxta; phallus with a long distal sclerite.

FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 11.1–11.6 mm. Abdomen. Genitalia ( Fig. 99) with papillae anales slender, slightly converging posteriorly; ductus bursae with complex sclerotization in anterior 0.6; signum large, paired lip-shaped, with an uninterrupted line of sclerotization between its two lateral projections.

DNA barcodes. The 19 barcode sequences of C. bernardoespinozai form a BIN (BOLD:AAA1074) with an average distance of 0.13% among the sequences, and a distance of 4.17% to its nearest neighbor, C. marianofigueresi .

Distribution. Chlamydastis bernardoespinozai has been collected from 200 to 700 m on both slopes of the central cordillera and in the rainforest of ACG.

Biology. This species has been reared from larvae feeding on Chrysophyllum cainito L. (n = 3), Chrysophyllum brenesii Cronquist (n = 8), and Pouteria izabalensis (Standl.) Baehni (n = 1) ( Sapotaceae ) ( Table 1).

Immature stages ( Fig. 125 ). Head amber; prothorax (T1) gray with a pair of fused black pinacula on shield; T2– T3 with a pair of small, rounded, lateral protuberances (smaller in T3), black with two longitudinal white lines; abdominal segments pale green with small, lateral, translucent pale beige protuberances; A10 pale orange.

Etymology. Chlamydastis bernardoespinozai is named for our Costa Rican friend and colleague Bernardo Espinoza in recognition of his curatorial and taxonomic contributions to the national biodiversity inventory of Costa Rica.
