Holotype. Male, Costa Rica, Puntarenas, P. N. Piedras Blancas, Alrededor de Est. el Bonito, 100 m, 4.x.2002, M. Moraga, INB0003545629 ( MNCR-A).

Paratypes (7♂, 2♀). See Appendix 1.

Diagnosis. Chlamydastis lindapitkinae is most similar to C. iangauldi but can be distinguished by its shorter, narrower uncus and the cornuti arranged in an irregular line in the vesica of the phallus.

Description. MALE ( Fig. 7 ). Head. Frons white; vertex white anteriorly to base of antennae, then yellowish, collar brown; labial palpus yellowish, first and second segments with a contiguous dark brown lateral band reaching ca. 0.5 length of second segment; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Dorsum and tegula yellowish brown. FW length 7.5–7.7 mm; FW ground color yellowish with two distinct irregular, oblique fasciae formed by small interrupted brown spots originating at costa at ca. 0.50 (median) and 0.75 (distal) distance from base to apex, joined at mid-termen by a dark brown dash; subbasal fascia weak, narrow, originating at a small dark spot on costa. HW dark grayish brown. Abdomen. Externally pale brown. Genitalia ( Fig. 55 ) with uncus short, pointed; gnathos membranous, inconspicuous; valva as described for species group; sacculus ca. 0.33 length of valva; lateral processes of juxta broadest in basal 0.5, slightly narrower and attenuate in distal 0.5; phallus with cornuti arranged in an irregular line ( Fig. 55a ).

FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 8.5–8.8 mm. Abdomen. Genitalia ( Fig. 93 ) with papillae anales narrowed and diverging posteriorly; sterigma simple, bearing a rounded setose median lobe posteriorly; ductus bursae wide, posterior end with sclerotized ring, broadened near middle, with small sclerotized patches; corpus bursae membranous, pear-shaped; signum oblong, spiny, with unsclerotized region in middle.

DNA barcodes. No sequence data are available for this species.

Distribution. Chlamydastis lindapitkinae is found in the southern Pacific lowlands of Costa Rica.

Biology. The food plant and immature stages are unknown.

Etymology. Chlamydastis lindapitkinae is a patronym for our colleague Linda Pitkin in recognition of her taxonomic contributions to the national biodiversity inventory of Costa Rica.
