(Figs. 44, 227–228, 400, Map 47)
Diagnosis.— Hypatopa bilobata is similar to H. solea in facies but differs from the latter by having a longer and apically narrower uncus; a more anteriorly directed gnathos; and a larger apical process of the ventral part of the valva. H. bilobata also has an entire ventroposterior margin of the gnathos; a twisted digitate process of the dorsal part of valva; a broadly rounded apical margin of the proximal flange of the dorsal part of the valva; a shallowly and apically bifurcate sclerite of the phallus; and a widely and deeply emarginate apex of the anellus, forming two straight, elongate, divergent, marginally setose, lateral lobes that are lacking in H. solea.
Description.—Head: Scales on vertex and frontoclypeus grayish brown tipped with pale grayish brown. Outer surface of labial palpus with segment 1 brown, segment 2 brown intermixed with pale-brown scales along apical margin, segment 3 brown intermixed with pale-brown scales; inner surface pale brown. Antennal scape brown intermixed with few pale-brown scales, pecten brown, flagellum with basal 4/5 brownish gray, apical 1/5 pale brown. Proboscis pale brown.
Thorax: Tegula and mesonotum brown. Legs dark brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing (Fig. 400): Length 5.0–7.0 mm (n = 15), brown intermixed with pale-brown scales and few dark-brown scales; basal 1/3 pale brown except for brown costa; apical 2/3 brown intermixed with few pale-brown and dark-brown scales; cell with three spots, one near middle, two on apical end along crossvein; marginal spots faint or absent. Undersurface brown. Venation (Fig. 44) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 straight and CuA2 broadly curved basally. Hindwing: Translucent pale brown gradually darkening to apex. Venation (Fig. 44) with cubitus 4-branched; M2 arising about 1/2 distance between distoposterior part of cell and branching point of M3 and CuA1.
Abdomen: Male genitalia (Figs. 227–228): Uncus gradually narrowed from wide base, narrowly rounded and acutely curved apically, sparsely setose, about equal in length to width of anal opening. Gnathos narrow, anteriorly directed band, confluent with tegumen; ventroposterior margin entire. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part basally protracting inwardly, widened to middle, gradually narrowing to near base of inwardly curved, apical process; process slightly curved from base, setose on outer surface, planate on inner surface; ventral margin setose, with a slightly protuberant ridge at base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process twisted slightly beyond base; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange extending ventrolaterally, apically subellipsoid, with broadly rounded apical margin, sparsely microtrichiate on basal 1/2, setose on apical 1/2 (represented by sockets); ventral margin crenulate apically, serrate laterally. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, slightly curved from middle; sclerite of phallus acutely curved at 2/3 and at base, bifurcate apically; anellus widely and deeply emarginate mesially, forming two elongate and divergent lateral lobes, each lobe with row of setae along lateral margin. Female Genitalia: Unknown.

Distribution (Map 47): Hypatopa bilobata is known from one collecting site on the Cordillera de Tilarán in west-central Costa Rica.
Etymology. The specific epithet bilobata is compound word from the Latin bi meaning two and lob meaning lobe, together refering to the two apicolateral lobes of the anellus.
