 Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Pitilla, Leonel, 510 m, 18.vi.2009, D. Martínez, reared from larva feeding on Pouteria campechiana (Sapotaceae), 09-SRNP-70878, GenBank accession code HM885042 (USNM).   
 Paratypes (5♂, 10♀). See Appendix 1.   
 Additional specimens (14♂, 2♀). See Appendix 1.   
 Diagnosis. Chlamydastis irenecanasae is most similar to C. dondavisi, but it can be easily distinguished by its smaller forewing length (7.0 vs. 9.0 mm) and several features of the male genitalia described below in the diagnosis of C. dondavisi.   
 Description. MALE (Fig. 42). Head. Frons mostly white with scattered dark brown scales, vertex mostly brown with scattered white scales; labial palpus fawn-cream, with scattered white scales on all segments; antenna with sensory setae ca. 3.0 times width of flagellomere. Thorax. Dorsum and tegula pale fawn brown, with band of white scales near anterior margin that extends to base of FW. FW length 7.0 mm; FW pale brown-ocherous with faint, ill-defined, slightly darker brown blotch near middle of hind margin with two or three small patches of raised brown and white scales; two or three tiny patches of raised brown scales in discal cell; usually with one or two pale red-brown lines in apical region. HW brown. Abdomen. Externally brown-scaled; segment 4 with lateral, membranous, conelike projections from pleural membrane (visible in dissections). Internally with sclerotized, elongate pleural processes of segments 6–7 extending deep into previous segment. Genitalia (Fig. 81) with uncus short, stout, slightly narrowed subapically; gnathos membranous; valva subtriangular with long, slender, armlike process from base extending well beyond uncus, curving near middle, with a long, slender, curved thorn at apex; specialized (arrowhead) setae along inner margin of armlike process, concentrated in basal 0.35; sacculus confined to basal 0.33 of valva with free, spinelike distal part extending behind valva; juxta with lateral processes more or less parallel-sided, rounded distally, not as long as plate of juxta; phallus pistol-shaped, vesica with long, slender, sclerotized process with three small distal teeth.   
 FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 7.0 mm; sometimes with narrow white line of scales from hind margin near middle of FW. Abdomen. Lacking conelike projections from pleuron. Genitalia (Fig. 116) with papillae anales rounded and slightly diverging posteriorly; ductus bursae long, slender, uniform in width, ca. 4 times length of corpus bursae, with region of longitudinal wrinkles in posterior 0.3; corpus bursae round with mustache-shaped signum, slightly attenuate at each end and narrowed in middle.   
 DNA barcodes. The six barcodes of C. irenecanasae form a uniform BIN (BOLD:AAA0116), with identical sequence data, with a distance of 4.33% to its nearest neighbor, C. dondavisi.   
 Distribution. Chlamydastis irenecanasae has been collected throughout the Pacific side of the country from ACG to ACOSA in the South. A few specimens have been light-trapped in the ACG at middle elevations.   
 Biology. This species has been reared from Pouteria campechiana Baehni (n = 3), Pouteria viridis (Pittier) Cronquist (n = 1), and Pouteria cainito L. (n = 1) (all Sapotaceae).   
 Etymology. The specific epithet is a patronym for Irene Cañas in recognition of her contributions to the national biodiversity inventory of Costa Rica.
