 Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Santa Rosa, Area administrativa, 295 m, 8.ix.2016, H. Cambronero and R. Franco, 16-SRNP-105662, GenBank accession code MW435313 (USNM).   
 Paratypes (1♂, 7♀). See Appendix 1.   
 Diagnosis. Chlamydastis marianofigueresi is superficially most similar to C. colleenhitchcockae; it is a conspicuously large species with a pale ground color and a dark line through the discal cell. The male genitalia of C. marianofigueresi are distinguished by the strongly hook-shaped process of the sacculus that bears the hairpencil.   
 Description. MALE (Fig. 12). Head. Frons, vertex and collar cream; labial palpus cream intermixed with brownish scales, second segment with an irregular brownish lateral band extending from base to ca. 0.5 length of segment; antenna with length of sensory setae ca. equal to width of flagellomere. Thorax. Dorsum and tegula cream. FW length 12.5 mm; FW grayish white with faint, irregular pale gray striations; a distinct, slender, black line in middle of discal cell ending at a small white dot; a short, ill-defined brown dash from costa ca. 0.15 distance from base to apex. HW pale brownish gray. Abdomen. Externally with brownish scales. Genitalia (Fig. 59) with uncus stout from a broad base, only slightly attenuate apically; anterior margin at intersection of lateral halves of tegumen slightly rounded; gnathos absent; valva with ovate dorsal part pointed apically bearing dense patch of specialized setae near termination of costa, irregularly triangular basal part representing sacculus ca. 0.4 length of valva, with long, dense well-developed haripencil; lateral processes of juxta long, narrow, truncate apically; phallus pistol-shaped, with two apically pointed, distal sclerites in vesica.   
 FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 16.0 mm. Abdomen. Genitalia (Fig. 97) with papillae anales somewhat parallel-sided, each with a slender line of sclerotization in anterior 0.5; ductus bursae short, broad, junction with corpus bursae somewhat ill-defined; signum ovate, spiny, with a continuous sclerotized ridge across axis.   
 DNA barcodes. The 12 barcode sequences of C. marianofigueresi form a BIN (BOLD:AAJ4197) with no genetic variability and a distance of 4.17% to its nearest neighbor, C. bernardoesinozai.   
 Distribution. Chlamydastis marianofigueresi has been collected in ACG from 295 to 1610 m elevation and in the Cordillera de Talamanca from 1400 to 1600 m elevation.   
 Biology. A single last instar (08-SRNP-36402) was collected on Pouteria reticulata (Sapotaceae); the cocoon is shown in Fig. 126.   
 Etymology. Chlamydastis marianofigueresi is named in honor of the late Peter Michael Mariano Figueres Olsen in recognition of his seminal and germinal support in expanding the rainforested area of Area de Conservación Guanacaste on the Caribbean slopes of Sector Rincon Rain Forest.
