Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Orosi, Manta Mecate , 587 m, 30.ix.2011, H. Cambronero and S. Ríos, 11-SRNP-104804, GenBank accession code MH827046 ( USNM).

Paratypes (11♂). See Appendix 1.

Diagnosis. Superficially, C. noramartinae is similar to C. vitorbeckeri . In both, the forewing has a somewhat twotoned pattern—pale yellow in the basal 0.33 and pale brown-ocherous in the distal 0.66 ( Fig. 45 ), with a slender copper crescent-shaped patch in the termen. The male genitalia of C. noramartinae can be distinguished from other members of the species group by the small, rounded uncus and the greatly reduced sacculus.

Description. MALE ( Fig. 45 ). Head. Frons and vertex pale yellow, with ocherous tufts on lateral vertex and collar, labial palpus brownish; antenna with sensory setae extremely short, sparse. Thorax. Tegulae and dorsum pale yellow, with irregular ocherous anterior band; FW length 5.1–5.7 mm; FW pale yellow in basal 0.33, delineated distally by an arched white line; distal 0.66 pale brown-ocherous with faint subcircular blotch in terminal area. HW pale grayish brown. Abdomen. Externally brown with two anteriormost segments pale yellow; conspicuous bushy hairpencil from end of abdomen. Genitalia ( Fig. 84 ) with uncus reduced to a short, rounded nub; gnathos absent; valva somewhat parallel-sided with fanlike arrangement of specialized setae originating near middle of apex of valva; lateral processes of juxta with group of setae at distal ends; phallus stout, curved at ca. 0.65 distance from base.

FEMALE. Unknown.

DNA barcodes. The three barcodes of C. noramartinae form a BIN (BOLD:ABW0965) with an average distance of 0.21% among sequences and a distance of 7.21% to the nearest neighbor, C. manuelzumbadoi .

Distribution. Chlamydastis noramartinae has been collected only in dry forest/dry lowland intergrade at ca. 600 m elevation in ACG.

Biology. The immature stages and food plants are unknown.

Etymology. Chlamydastis noramartinae is named in honor of Nora Martin in recognition of her administrative and logistic contributions to the national biodiversity inventory of Costa Rica.
