Holotype. Male, Costa Rica, Alajuela, ACG, Sector San Cristobal, Río Blanco Abajo, 500 m, 27.xi.2012, Elda Araya, reared from larva feeding on Terminalia oblonga (Combretaceae) , 12-SRNP-5249, GenBank accession code MW435315 ( USNM).

Paratypes (8♂, 5♀). See Appendix 1.

Additional specimens examined (14♂, 6♀). See Appendix 1.

Diagnosis. Superficially, C. munifigueresae is very similar to C. ronaldzunigai – both are small species with a somewhat two-toned forewing pattern, pale in the basal 0.4 and dark in the distal 0.6. However, the two are easily separated by features of the male genitalia. In general, the tegumen and valva are considerably narrower in C. munifigueresae , and the uncus is broadly spatulate apically (pointed apically in C. ronaldzunigai ).

Description. MALE ( Fig. 48 ). Head. Frons beige, vertex beige with light brown scales; labial palpus beige; antenna with sensory setae ca. 1.5 times width of flagellomere. Thorax. Tegula and dorsum golden yellow. FW length 4.9– 5.2 mm; FW pale fawn in basal 0.33, distal 0.66 with complex pattern of brown and red-brown with round fawn spot near end of discal cell; two conspicuous patches of raised brown scales, first at outer margin of fawn brown basal region, second midway between first and tornus. HW dark brown. Abdomen. Brown externally. Genitalia ( Fig. 87 ) with uncus long, slender, strongly curved downward in distal 0.3, with enlarged spatulate apex bearing a patch of short setae; gnathos slender, somewhat semicircular, membranous; valva split longitudinally into slen- der, shorter basal part and a much larger, apically-attenuate dorsal part bearing specialized setae on basal 0.6 of costa; phallus short, broad, curved, with slender pointed projection distally.

FEMALE. Head and Thorax. Essentially as described for male, except sensory setae of antenna short, sparse; FW length 7.8–8.5 mm. Abdomen. Genitalia ( Fig. 121 ) with ostium lightly sclerotized; ductus bursae simple, wide, intersecting ovoid corpus bursae at one side; signum a long, slender dentate patch.

DNA barcodes. The 19 barcode sequences of C. munifigueresae form a BIN (BOLD:AAY4673) with an average distance of 0.06% among sequences and a distance of 6.96% to its nearest neighbor, C. ronaldzunigai .

Distribution. Chlamydastis munifigueresae has been collected in the central Pacific lowlands, in northern Guanacaste (ACG) and in the lowlands of Sarapiquí from 80 to 500 m elevation.

Biology. This species has been reared from Terminalia amazonia (Combretaceae) (n = 8).

Etymology. The specific epithet is a patronym for Muni Figueres in recognition of her contributions to the biopolitics of the national biodiversity inventory of Costa Rica.

Unassigned to Species Group

One new species from Costa Rica and one previously described species do not fit convincingly into any of the species groups circumscribed above, and these two are treated below.
