 Holotype. Male, Costa Rica, Limón, Area de Conservación La Amistad Caribe, Veragua Rainforest, Campamento, 400 m, 23.iv.2009, R. Villalobos, INB0004210886, GenBank accession code MH827053 (MNCR-A).   
 Paratypes (9♂, 6♀). See Appendix 1.   
 Additional material examined. See Appendix 1.   
 Diagnosis. Superficially, C. manuelzumbadoi can be distinguished from C. noramartinae and other species in the group by the FW pattern, which is mostly pale throughout except for an ill-defined olive median fascia and a distinct, semicircular, terminal blotch. It is superficially most similar to C. cystiodes but can be distinguished by the extremely short and sparse sensory setae of the male antennae, which are long and dense in C. cystiodes, typical of most Chlamydastis. The male genitalia can be distinguished from those of congeners by the small triangular sacculus.   
 Description. MALE (Fig. 44). Head. Frons and vertex cream-ocherous; labial palpus cream-ocherous; antenna with sensory setae extremely short, sparse. Thorax. Dorsum and tegula mostly white intermixed with tan scales, infrequently with a narrow band of brown scales immediately posterior to collar. FW length 7.4–7.9 mm; FW white with faint, ill-defined, median fascia, broad at costa and nearly obsolete at hind margin; a few faint, illdefined spots along costa; a large blackish brown orbicular blotch in terminal area, bordered proximally by white ground color. Abdomen. Externally white with fawn-ocherous overscaling; a cream tuft from segment A7. Genitalia (Fig. 83) with uncus small, triangular; valva rounded apically with specialized setae arranged somewhat fanlike, originating from a dense patch at apex of costa of valva, sacculus long, with a straight ventral edge; juxta with slender lateral lobes, each distally setose; phallus large, curved in apical 0.4, with flattened distal process.   
 FEMALE. Head and Thorax. Essentially as described for male, except FW length 8.0–9.0 mm. Abdomen. Genitalia (Fig. 118) with papillae anales slender, slightly rounded and weakly diverging posteriorly; ductus bursae long, slender; corpus bursae elongate-ovate with mustache-shaped signum, attenuate at each end and narrowed in middle, spiny throughout with fewer spines medially.   
 DNA barcodes. The 74 barcode sequences of C. manuelzumbadoi form a uniform BIN (BOLD:AAA0106) with an average distance of 0.07% among them and a distance of 7.50% to its nearest neighbor, C. noramartinae.   
 Distribution. Chlamydastis manuelzumbadoi has been collected from 140 to 610 m elevation in rain forest in ACG and in the Caribbean region on the east coast of Costa Rica.   
 Biology. This species has been reared from larvae feeding only on Vochysia ferruginea Mart. (n = 21) (Vochysiaceae) (Table 1).   
 Immature stages (Fig. 133). Head amber with a pair of oblique dark brown bands subdorsally; T1 pale greenish in anterior 0.2, pale brown in posterior 0.8 with black and white lateral bands; T2 and T3 dark brown; A1 white in anterior 0.5, dark brown in posterior 0.5; A2 dark brown; A3 and A4 light brown with a whitish irregular posterior band; A5 pale brown; A6 dark brown; A7–A10 brown with broad, pale greenish dorsal band; A3–A6 with short white bands laterally, followed by a continuous white band laterally on A7–A10.   
 Parasitoids. Parasitoids recorded from ACG include the following: Hymenoptera: Braconidae: Microgastrinae: Hypomicrogaster Whitfield 17 (e.g., DHJPAR0039018).   
 Etymology. The specific epithet is a patronym for Manuel Zumbado in recognition of his curatorial, administrative, and taxonomic contributions to the national biodiversity inventory of Costa Rica.
