Figures 30, 74, 109  
 Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Orosi, Estación Maritza, Casa Rafa, 579 m, 4.vi.2011, H. Cambronero and R. Franco, 11-SRNP-104260, GenBank accession code JQ547599 (USNM).   
 Paratypes (18♂, 12♀). See Appendix 1.   
 Diagnosis. Chlamydastis jimlewisi is most similar to C. jimmilleri, but it can be easily distinguished by the shape of the valva: a broader subbasal portion and a more strongly curved outer margin.   
 Description. MALE (Fig. 30). Head. Frons and vertex whitish intermixed with grey scales, collar yellow with brown scales intermixed; labial palpus grayish; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Prothorax and base of tegulae ocherous, meso- and metathorax mostly cream intermixed with a few ocherous scales; often with two lateral black lines on mesothorax. FW length 10.4–10.7 mm; FW with middle 0.66 somewhat checkered dark brown and pale ocherous with bluish white (iridescence) highlights; three round, pale golden-ocherous spots: one ill-defined near base of wing and two well-defined along termen, latter separated by a narrow line of brown ground color. HW dark gray-brown. Abdomen. Externally brown. Genitalia (Fig. 74) with uncus stout, conical; gnathos membranous; valva with lower margin undulate, rounded at base, broadest ca. 0.33 distance from base to apex, slightly narrower in distal 0.25; specialized setae from near middle of costa; lateral processes of juxta long-digitate, slightly curved dorsally, reaching lower base of valva; phallus large, curved, with long, curved distal rod extending well beyond apex of phallus; phallobase rounded.   
 FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 10.7–11.6 mm. Abdomen. Genitalia (Fig. 109) with papillae anales slightly diverging and rounded posteriorly; sterigma with broad, strongly sclerotized, posterior band with acute lateral projections, setose at posterior margin, anterior part of sterigma semicircular, wrinkled; ductus bursae with sclerotized enlargement in posterior 0.5, narrow and membranous in anterior 0.5; corpus bursae elongate pear-shaped with a small peanutshaped, spiny signum unsclerotized in a narrow region through its middle.   
 DNA barcodes. The 37 barcode sequences of C. jimlewisi form a cluster (BOLD:AAJ4199) with an average distance of 0.47% among the sequences, and a distance of 2.25% to its nearest neighbor, C. jimmilleri.   
 Distribution. Chlamydastis jimlewisi has been collected mainly in dry forest of Guanacaste during the rainy season, and in the dry forest/dry forest lowland intergrade from 300 m to 800 m.   
 Biology. The food plants and immature stages remain unknown.   
 Etymology. Chlamydastis jimlewisi is named in honor of James Lewis in recognition of his continuous curatorial and taxonomic contributions to the national biodiversity inventory of Costa Rica.
