Figures 36, 37, 78, 113, 132  
 Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Orosi, Estación Maritza, Manta Mecate, 30.ix.2011, H. Cambronero and S. Rios, 11-SRNP-104823, GenBank accession code MH827047 (USNM).   
 Paratypes (22♂, 14♀). See Appendix 1.   
 Diagnosis. Chlamydastis johnnoyesi is most similar to C. paulthiaucourti but is easily distinguished by the patch of specialized setae of the male genitalia, which is much larger in C. johnnoyesi. The lateral processes of the juxta also are much larger than those of C. paulthiaucourti.   
 In C. deflexa (from French Guiana) the lateral processes of the juxta broaden toward the tips, and the juxta itself is conspicuously sclerotized with a mesal notch. In C. johnnoyesi the lateral processes of the juxta are nearly uniform in width with a narrow tip, and the juxta is only lightly sclerotized.   
 Description. MALE (Fig. 36). Head. Frons cream; vertex pale brown with scattered white scales; labial palpus with first segment dark brown laterally, second and third segments ocherous with a narrow white line; antenna with length of sensory setae ca. equal to width of flagellomere. Thorax. Dorsum and tegula cream. FW length 7.0– 7.2 mm; FW two-toned, mostly cream in basal 0.7 with some brownish markings, darker in distal 0.25; costa deflexed in apical 0.25, termen occupied by a large ovate brown blotch surrounded by a narrow line of cream and brownish scales; irregular oblique brown line at 0.75 distance from base to apex, extending from just below costa toward hind margin ca. 0.7 distance from base to tornus. HW light brown. Abdomen. Externally pale brown. Male genitalia (Fig. 78) with uncus slightly longer than in other species of species group; gnathos membranous, lacking an upturned mesal process at junction of arms; valva with conspicuously long portion of armlike process beyond elbowed bend, with a long patch of specialized setae; lateral processes of juxta long; phallus broad, weakly curved; lacking conspicuous cornuti.   
 FEMALE (Fig. 37). Head. Essentially as described for male, except sensory setae of antenna short, sparse. Thorax. As in male, except FW length 7.8–8.5 mm; FW with evenly curved costa (rather than deflexed) and larger dark brown blotch at apex. Abdomen. Genitalia (Fig. 113) with papillae anales rounded and slightly diverging posteriorly; a rounded-triangular lobe at middle of anterior portion of sterigma; ductus bursae with a sclerotized band; signum pointed at both ends.   
 DNA barcodes. The 84 barcodes of C. johnnoyesi form a BIN (BOLD:AAA0918) with an average distance of 0.03% among the barcodes and a distance of 4.66% to its nearest neighbor, C. paulthiaucourti.   
 Distribution. Chlamydastis johnnoyesi has been collected in ACG in the dry forest and dry forest-rain forest lowland intergrade, from 40 to 860 m elevation.   
 Biology. Chlamydastis johnnoyesi has been reared only from larvae feeding on Clethra lanata M. Martens and Galeotti (n = 20) (Clethraceae) (Table 1).   
 Immature stages (Fig. 132). Head red; prothoracic shield black; body yellowish with no distinct pattern elements; caudal segments light yellow.   
 Parasitoids. Parasitoids from ACG include: Hymenoptera: Ichneumonidae: Campopleginae: Campoplex Janzen 27 (n = 2, e.g., DHJPAR0055137).   
 Etymology. Chlamydastis johnnoyesi is a patronym for John Noyes in recognition of his many contributions to the national biodiversity inventory of Costa Rica.
