Holotype. Male, Costa Rica, Guanacaste, ACG, Sector Cacao, Sendero Derrumbe , 1220 m, 10.92918, −85.46426, 13.viii.1997, larva feeding on Pouteria reticulata , em: 10.ix.1997, R. Moraga, 97-SRNP-1651 ( USNM).

Paratypes (3♀). See Appendix 1.

Diagnosis. Superficially, C. colleenhitchcockae is nearly identical to C. marianofigueresi , but the pattern elements of the former have a richer, slightly more yellowish-brown hue compared to the slightly paler and grayer ground color of C. marianofigueresi . With an average FW length of ca. 16 mm, females of C. colleenhitchcockae are among the largest Chlamydastis (along with C. marianofigueresi ) in Costa Rica. The male genitalia of C. colleenhitchcockae are very similar to those of C. marianofigueresi , but can be distinguished by several subtle features: a slightly shorter, rounder valva; a somewhat blade-shaped unsclerotized region at the base of the valva (more irregularly rounded in C. marianofigueresi ); a more rounded antero-dorsal junction of the tegumen; a rounded dorso-posterior margin of the juxta (weakly undulate in C. marianofigueresi ); and a slightly broader phallobase.

Description. MALE ( Fig. 13 ). Head. Frons cream, vertex and collar pale fawn brown; labial palpus cream with brown lateral band along first segment and 0.75 length of second segment; antenna with length of sensory setae ca. equal to width of flagellomere. Thorax. Dorsum and tegula pale fawn brown with ill-defined transverse brown line on prothorax. FW length 12.0 mm; FW ground pale fawn with small, faint, ill-defined patches of yellowish brown, forming an incomplete fascia in postmedial area; a distinct, slender, black line in middle of discal cell ending in a small white dot with a few dark scales at its costal margin; irregular, pale fawn brown line in terminal region, with small, rounded spot near middle. HW pale yellowish brownish. Abdomen. Externally yellowish brown. Genitalia ( Fig. 59 ) with uncus stout from a broad base, nearly parallel-side to apex; anterior margin at intersection of lateral halves of tegumen shallowly rounded; gnathos absent; valva short, subovate, with dense patch of specialized setae from termination of costa, lower part of valva (sacculus) subtriangular, large, ca. 0.5 length of valva, with distinct basal, hook-shaped process bearing long, dense hairpencil; lateral processes of juxta long, narrow, truncate apically, dorso-posterior margin of juxta concave; phallus pistol-shaped, distal 0.5 sclerotized at dorsum and venter, phallobase slightly expanded, vesica with a slender sclerite.

FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 14.5–17.0 mm. Abdomen. Genitalia ( Fig. 98) with papillae anales moderately uniform in width throughout, inner margin with a pair of slender lines of sclerotization in basal 0.5 and a diffuse patch of minute teeth in middle; ductus bursae short, immediately broadened into corpus bursae without defined junction; corpus bursae pear-shaped, signum orbiculate, with a continuous sclerotized ridge across axis.

DNA barcodes. There are no barcodes of this species.

Distribution. Chlamydastis colleenhitchcockae has been collected from 1200 to 1420 m elevation in the cloud forest of ACG.

Biology. This species has been reared from larvae feeding on Pouteria reticulata (Engl.) Eyma (n = 4) ( Sapotaceae ) ( Table 1).

Immature stages. Head reddish brown; thorax with six to eight black dots; abdominal segments pale green with white hairs, with a brown to purple segmented lateral line.

Etymology. Chlamydastis colleenhitchcockae is named in honor of Mrs. Colleen Hitchcock of the greater Boston area, in recognition of her two decades of intense enthusiasm towards the processes that created ACG, and her contributions in many different contexts.
