Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Pitilla, Sendero Memos , 774 m, 2.iv.2011, H. Cambronero and F. Quesada, 11-SRNP-101977, GenBank accession code JQ545482 ( USNM).

Paratypes (18♂, 1♀). See Appendix 1.

Diagnosis. Chlamydastis antonioazofeifai is most similar to C. anniapicadoae , but the two can be distinguished by size ( C. antonioazofeifai is slightly smaller); color of the prothorax in the male (shiny white in C. antonioazofeifai , intermixed with a few pale brown scales in C. anniapicadoae ), and FW ground color (paler in C. antonioazofeifai ). The male genitalia of C. antonioazofeifai are easily distinguished from those of C. anniapicadoae by the rounded apex of the valva.

Description. MALE ( Fig. 10 ). Head. Frons and vertex shiny white, collar white with a few scattered brown scales; labial palpus mostly cream, first segment and basal 0.5 of second segment with a faint, lateral brown band; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Dorsum and tegula mostly shiny white; FW length 7.3–8.2 mm; FW white with a distinct, narrow, black line through middle of discal cell ending in a small hook; costa with a small dark grayish brown dot at ca. 0.15 distance from base to apex, a narrow semicircular patch near mid-costa, and a diffuse, dark brown, rhomboidal patch ca. 0.75 distance from base to apex. HW pale beige. Abdomen. Externally white, often with a pair of slender scaleless lines revealing abdomen subdorsally on A2 or A3. Genitalia ( Fig. 58 ) with uncus stout, truncated apically; anterior margin at intersection of lateral halves of tegumen V-shaped; gnathos absent; valva with ovate dorsal part rounded apically bearing dense patch of specialized setae near termination of costa, irregularly triangular basal part representing sacculus ca. 0.4 length of valva, with hairpencil weakly developed; basal part of juxta large, with short, distally truncate, lateral processes; phallus with two distal thorns on a median sclerite in vesica.

FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 8.7–9.2 mm. Abdomen. Scaleless lines absent. Genitalia ( Fig. 95 ) with papillae anales slender, relatively uniform in width throughout, slightly divergent posteriorly, with distinct line of sclerotization in anterior 0.5; ductus bursae broad, mostly uniform in width, broadened slightly at ill-defined junction with corpus bursae; corpus bursae oblong, signum large, subtriangular, spiny, with a continuous, slightly curved, sclerotized line across axis.

DNA barcodes. The 12 barcode sequences of C. antonioazofeifai form a BIN (BOLD:AAA1168) with an average distance of 0.17% among them, and a distance of 6.74% to its nearest neighbor, C. anniapicadoae .

Distribution. Chlamydastis antonioazofeifai has been collected in the middle elevations of ACG and the northern Caribbean region.

Biology. The immature stages and food plant are unknown.

Etymology. Chlamydastis antonioazofeifai is named in honor of Antonio Azofeifa in recognition of his technical support of the national biodiversity inventory of Costa Rica.
