Paratypes ( 7♂ , 3♀ ). See Appendix 1. Diagnosis. Chlamydastis luisdiegogomezi can be differentiated from other species of the species group found in Costa Rica by its shorter, slightly narrower uncus and by the narrower and straighter armlike projections of the valva. The female genitalia differ from other species of the group by the longer, narrower signum located in the anteriormost portion of the corpus bursae. Description. MALE ( Fig. 38 ). Head . Frons and vertex white; labial palpus with first segment dark brown, second and third segments ocherous, a narrow white ring at end of second segment; antenna with length of sensory setae ca. equal to width of flagellomere. Thorax . Dorsum and tegula brown. FW length 7.7–8.5 mm ; FW two-toned, mostly cream in basal 0.75 with some light brownish markings; costa deflexed in apical 0.25, apical region with large ovate gray blotch surrounded by irregular line of pale brownish scales; an oblique irregular line ca. 0.75 distance from base to apex extending from costa toward hind margin, ending in an ill-defined, pale brown blotch ca. 0.7 distance from base to tornus. HW pale brown. Abdomen . Externally pale brown. Genitalia ( Fig. 79 ) with uncus slender; gnathos membranous; valva with armlike process slender, straight, with patch of specialized setae; lateral processes of juxta straight; phallus curved throughout with slender pointed apex. FEMALE ( Fig. 39 ). Head . Essentially as described for male, except sensory setae of antenna short, sparse. Thorax. Essentially as described for male, except FW length 9.2–10.3 mm ; FW with an evenly curved costa (rather than deflexed apically) and larger dark brown blotch in subterminal region. Abdomen . Genitalia ( Fig. 114 ) with papillae anales rounded and slightly diverging posteriorly; ductus bursae with a sclerotized band and a long and thin dentate signum located at anteriormost portion of corpus bursae. DNA barcodes. We have no sequence data for this species. Distribution. Chlamydastis luisdiegogomezi is primarily a lowland species, ranging from about 150–200 m , with a single individual from 700 m . It has been collected most frequently in Heredia Province , with a few individuals from Limón Province . Biology. Nothing is known of the early stages. Etymology. Chlamydastis luisdiegogomezi is named in honor of the late Luis Diego Gómez in recognition of his administrative and taxonomic contributions to the national biodiversity inventory of Costa Rica .
