 Holotype. Male, Costa Rica, Cartago, La Amistad Pacífico, Paraíso, P. N. Tapantí-Macizo de la Muerte, 3.5 km siguiendo hacia Rio Humo, 1650 m, 8–10.ix.2010, E. Phillips, INB0004263587, GenBank accession code MH827051 (MNCR-A).   
 Paratypes (10♂, 3♀). See Appendix 1.   
 Diagnosis. Chlamydastis anniapicadoae is superficially most similar to C.antonioazofeifai, but in C. anniapicadoae the FW ground color has more grayish overscaling, the preapical costal blotch is slightly smaller, and the FW length is slightly greater, especially in the female. The male genitalia of C. anniapicadoae are easily distinguished by the truncate apex of the valva.   
 Description. MALE (Fig. 9). Head. Frons, vertex and collar cream; labial palpus cream intermixed with brownish scales, second segment with an irregular brownish lateral band reaching ca. 0.5 distance of segment; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Dorsum and tegula mostly cream intermixed with brownish scales. FW length 8.0– 9.1 mm; FW grayish white with faint, curvy, irregular pale gray striations; a distinct, narrow, curved black line through middle of discal cell ending in a small hook; a black dash from costa ca. 0.15 distance from base to apex, extending toward, but ending before curved line in discal cell. HW pale brownish gray. Abdomen. Externally brownish, first segment paler dorsally. Genitalia (Fig. 57) with uncus stout from a broad base; anterior margin at intersection of lateral halves of tegumen V-shaped; gnathos absent; valva with ovate dorsal part truncate apically bearing specialized setae at termination of costa, irregularly triangular basal part representing sacculus ca. 0.4 length of valva, with hairpencil poorly developed; lateral processes of juxta long, narrow, truncate apically; phallus with two small thornlike cornuti.   
 FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 10.5–12.0 mm. Abdomen. Genitalia (Fig. 94) with papillae anales with outer margin rounded in distal 0.33, together weakly chordate; ductus bursae short, broad, junction with corpus bursae ill-defined; signum ovate, spiny, with a continuous sclerotized line across axis.   
 DNA barcodes. The six barcode sequences of C. anniapicadoae form a BIN (BOLD:AAV3795) with an average distance of 0.31% among them, and a distance of 7.06% to its nearest neighbor, C. antonioazofeifai.   
 Distribution. Chlamydastis anniapicadoae has been collected in the Cordillera de Talamanca from 1200 to 1650 m and in the rain forest of ACG at 1600 m.   
 Biology. Larval hosts and immature stages are unknown.   
 Etymology. Chlamydastis anniapicadoae is named in honor of Annia Picado in recognition of her technical support of the national biodiversity inventory of Costa Rica.
