Etymology. The name refers to Tapanti National Park, Costa Rica, the location where C. tapantia has been found most frequently.

Diagnosis. The species is readily recognized by its maculation. Th e dark chocolate line running from the middle of the lower forewing margin to the outer margin in combination with the chocolate marginal bands are diagnostic.

Description. Male. Head – Palps very small, less than eye width, third segment half length of first and second segments, which are equal in size. Palp with chocolate-brown scaling on outer and dorsal surface, cream on inner and ventral surfaces; frons squarish; ground cream with chocolate-brown dusting becoming dense dorsally; scape cream; area between antennae dirty cream; collar chocolate with erect brown scales. Antenna bifasciculate, segments Y-shaped, orange on ventral surface, dorsal scaling brown, light- er toward antennal tip. Setal rows arranged in two groups per segment, one at midpoint of segment, other at distal end on lateral expansions of segment. Thorax and abdomen – Thorax cream dorsally; abdominal segments cream with heavy brown dusting laterally especially on first segment; ventral surface cream. Legs dusted with fine brown scales dorsally, otherwise cream. Metathoracic tibia slightly swollen. Two pairs of tibial spurs on hind legs, one pair on middle legs. Wings – forewing length 15 mm; ground color cream; costa and margin of forewing chocolate brown; chocolate submarginal line begins subapically on costa and runs parallel to wing margin to slightly below midpoint, (between M1 and M2) then angles to midpoint of lower margin of wing. Postmedial line (PM) indistinct. Discal spot chocolate, small but prominent. Hindwing ground cream, crossed by a series of brown lines parallel to margin. Discal dot distinct, medial line prominent. Wing margin dark brown, chocolate scaling forming a subapical spot. Fringe brown. Dorsal surface cream with brown dusting overlay particularly where PM line originates subapically, line incomplete, not extending to anal edge of wing. Margin with distinct line of chocolate scales. Discal spots distinct on both wings. Apex with a well defined white area. Male genitalia – Uncus rod shaped. Valva elongate, sweeping

upward slightly toward uncus. Costal edge sclerotized with hairlike bristles below costal edge more numerous toward valve apex, which is acute and slants slightly upward. Arms of gnathos indistinct, medial junction forming oval pad and covered with spines. Anellar arms swollen and appear as an inward extension of costa. Tegumen arms extended diagonally to fuse posteriorly below uncus. Vincular arms straight. Furca diverted to left to gnathos, apex pointed; bristle area occupies terminal 15%. Right juxtal arm swollen at base. Saccus with squared base. Aedeagus straight, lightly sclerotized, with basal keel, expands medially, apex acutely pointed. Vesica expanded slightly with patch of cornuti basally and hair-like bristles distally. No distinct features on pelt. Female. Antenna filiform, otherwise similar to male but slightly larger (FW length 16 mm) and with chocolate dusting more extensive. Underside of forewing with distinct apical spot. Female genitalia – Anal papillae elongated, tip rounded, extended on ventral side. Posterior apophyses 2 × length of anterior apophyses, thin, expanded and paddle shaped at terminus. Anterior apophyses kinked at posterior end, paddle shaped at terminus, but less broadly than posterior apophyses. Seventh tergite forms lightly sclerotized shield over ostium. Ostium sclerotized, oval with posterior margin deeply concave on left side. Ductus very long; bursa saclike; signa a narrow slit. Pelt without distinct features.

Distribution and biology. C. tapantia has been collected in the provinces of Alajuela, Cartago, and Heredia, Costa Rica. It has been found along a rather narrow elevational range, from 1100–1600 m. Adults are on the wing throughout the year.
