Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Mundo Nuevo, Pozo # 3, 634 m, 27.xi.2008, F. Quesada and S. Ríos, 08-SRNP-108399, GenBank accession code JQ553540 ( USNM).

Paratypes (22♂, 2♀). See Appendix 1.

Diagnosis. Chlamydastis angelsolisi is most similar to C. lindapitkinae and C. iangauldi . Superficially, the FW is slightly more gray-green than the pale brown of the latter two species. The male genitalia of C. angelsolisi can be

distinguished by the processes of the juxta, which are broadened in the distal half, and the spines of the cornuti, which are slenderer than in congeners and clustered at one end of the vesica.

Description. MALE ( Fig. 6 ). Head. Frons white; vertex and collar yellowish; labial palpus yellowish, first and second segment with a lateral dark brown band reaching ca. 0.75 length of second segment; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Dorsum and tegula grayish yellow. FW length 7.5–7.8 mm; FW ground color mostly whitish, with irregular grayish yellow overscaling, most dense in basal 0.7; three irregular, oblique fascia formed by interrupted blackish brown subrectangular spots originating at costa at ca. 0.25 (subbasal), 0.50 (median), and 0.75 (distal) distance from base to apex; subbasal fascia weak, arching from costa to near middle of hind margin; median fascia extending obliquely from costal blotch, intersecting similar blotch near mid-termen; distal fascia composed of a series of small blackish brown dots, gently arched from costa to blotch near mid-termen; a series of small blackish brown dots in terminal area. HW dark gray. Abdomen. Externally pale brown. Genitalia ( Fig. 54 ) with a short, pointed uncus; gnathos membranous, inconspicuous; valva as described for species group; sacculus ca. 0.33 times length of valva; lateral processes of juxta broad in distal 0.5; phallus unmodified with patch of slender spines (i.e., cornuti) clustered at end of vesica ( Fig. 54a ).

FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 9.6–9.8 mm. Abdomen. Genitalia ( Fig. 92 ) with papillae anales relatively slender throughout, slightly diverging posteriorly; sterigma simple with a distinctly rounded, setose, median lobe posteriorly; ductus bursae narrow posteriorly, expanded in middle with some small sclerotized patches; corpus bursae membranous, pearshaped, signum oblong, spiny, with narrow unsclerotized region through its middle.

DNA barcodes. The 18 barcodes of C. angelsolisi form a uniform BIN (BOLD:AAD8081) with an average distance of 0.07% among sequences, and a distance of 5.63% to its nearest neighbor, C. jimmilleri + C. jimlewisi .

Distribution. Chlamydastis angelsolisi is a common species in the dry forest of ACG, from 200 to 300 m.

Biology. The food plant and immature stages remain unknown.

Etymology. Chlamydastis angelsolisi is a patronym for Angel Solís in recognition of his curatorial and taxonomic contributions to the national biodiversity inventory of Costa Rica.
