Diagnosis.— Hypatopa rabio possesses the following unique combination of features: an uncus and gnathos that are absent; a ventral part of valva with an apical process that is bifurcate apically; a ventral part of valva with a slightly raised setose lobe beneath base of apical process; a row of subapical setae on outer surface of the apical process of the ventral part of the valva; an acutely and laterally protracted proximal flange of the dorsal part of the valva; and an anellus that is gradually narrowed from a widened base, truncate apically, with a row of marginal setae on the apical 2/3, with a large setal cluster on the basal 1/3. This combination of character states differentiates it from all other congeners.

Description.—Head: Vertex and frontoclypeus grayish brown. Outer surface of labial palpus with segment 1dark brown, segment 2 dark brown intermixed with brown, and pale-brown scales along apical margin, segment 3 dark brown intermixed with few pale-brown scales; inner surface with segments 1–2 pale brown, segment 3 darkbrown intermixed with few pale-brown scales. Antennal scape and pecten grayish brown, flagellum with basal 4/5 brownish gray, apical 1/5 pale brown. Proboscis grayish brown.

Thorax: Tegula and mesonotum brownish gray. Legs dark brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 401 ): Length 4.1–5.8 mm (n = 24), brown intermixed with few pale-brown and few dark-brown scales; concolorous brown or basal 1/3 slightly paler than apical 2/3; cell with three spots present or absent, if present, one near middle, two on apical end along crossvein. Undersurface brown. Venation ( Fig. 45 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 about 1/3 longer than CuA2 and CuA2 broadly curved. Hindwing: Translucent pale brown. Venation ( Fig. 45 ) with cubitus 4-branched; M2 arising slightly beyond 1/2 distance between distoposterior part of cell and branching point of M3 and CuA1.

Abdomen: Male genitalia ( Figs. 229–230 ): Uncus and gnathos absent. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part basally protracting inwardly, broadly rounded to near large setose lobe at base inwardly curved, apical process; process wide basally, gradually narrowing apically, forming narrowly bifurcate apical part; apical part with short row of marginal setae on outer surface, planate on inner surface; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; process narrow basally, gradually widening apically; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange narrowly ellipsoid from protracted base, densely setose. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva, broadly curved at 2/3; anellus gradually narrowed from widened base, truncate apically, with row of short marginal setae on apical 2/3, and large setal cluster on basal 1/3. Female Genitalia ( Fig. 268 ): Apophyses posteriores about 3X longer than apophyses anteriores. Ostium bursae within membrane posterior to seventh segment; short duct connecting ductus seminalis and anterior part of dustus bursae from shared point. Posterior margin of seventh sternum laterally emarginate, bearing five densely packed clusters of piliform sex scales. Ductus bursae slightly greater than 2X longer than apophyses posteriores; slightly spinulate on anterior 1/4. Corpus bursae ovoid, sparsely spinulate throughout; signum large, posterior end acutely curved anteriorly.

Distribution (Map 48). Hypatopa rabio is known from one collecting site on the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet rabio is derived from the Latin rabies meaning, madness or rage.
