Holotype. Male, Guatemala, Cayuga, [no date], W. Schaus, USNM Type No. 22309 ( USNM).

Material examined (33♂, 11♀). See Appendix 1.

Diagnosis. Chlamydastis orion is most similar to C. montywoodi . It can be distinguished superficially from the latter by the white basal third of the FW in the male of C. orion , which is chestnut brown in C. montywoodi . The male genitalia of C. orion differ from those of C. montywoodi in the position of the specialized setae of the valva, which originate from near the base of the costa of the valva in C. orion and from the subapical region of the costa of the valva in C. montywoodi .

Description. MALE ( Fig. 32 ). Head. Frons cream-ocherous; vertex and collar brown with scattered cream scales; labial palpus cream; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Tegula white, with two small brownish dots near base. FW length 8.2–8.4 mm; FW with basal 0.33 mostly white with scattered small dark strigulae, costa brownish, distal 0.33 mostly dark brown variegated with ocherous and gray, an illdefined blotch of bluish gray scales in tornal area with two semi-square grayish spots arising from internal part of blotch. HW brownish. Abdomen. Externally pale brown. Genitalia ( Fig. 76 ) with uncus long, slender from broad base; gnathos membranous; valva parallel-sided in basal 0.5, evenly attenuate in distal 0.5, costa and sacculus illdefined, specialized setae originating subbasally from costa; lateral processes of juxta short, wide, with rounded tip; phallus short, stout, vesica lacking cornuti.

FEMALE ( Fig. 33 ). Head. Essentially as described for male, except sensory setae of antenna short, sparse. and Thorax. Dorsum brown; FW length 10.7 mm; basal 0.33 of FW with small patches of brown, gray, and ocherous scales; shiny bluish gray blotch in subcostal forming an irregular subterminal fascia interrupted near tornus by a brown line, narrowly border by cream. HW pale grayish brown. Abdomen. Genitalia ( Fig. 111 ) with outer margins of papillae anales parallel; sterigma a narrow, sclerotized band, perimeter of ostium bursae lightly sclerotized; ductus bursae wide; corpus bursae ovate with rhomboid signa.

DNA barcodes. The 59 barcode sequences of C. orion form a BIN (BOLD:AAA1164) with an average distance of 0.13% among samples and a distance of 9.87% to the nearest neighbor, C. bobandersoni . GenBank accession code JQ545473 for 11-SRNP-101965.

Distribution. Chlamydastis orion has been collected in Guatemala and Costa Rica. In Costa Rica, it has been found on the Pacific and Caribbean slopes and from 0 to 1300 m in the central mountain range. In ACG it has been recorded from 360 to 1050 m in rain forest and intermediate dry forest-rain forest habitat.

Biology. The early stages are unknown.
