(Figs. 31, 159–160, 366, Map 30)
Diagnosis.— Hypatopa arxcis is similar to H. hera and H. limae in facies but differs from the latter two by having a shorter uncus; a larger setose lobe at base of apical process of the ventral part of the valva; and a larger proximal flange of the dorsal part of the valva. H. arxcis also has an outer margin of the proximal flange that is nearly entire; and a basally widened anellus that is constricted subapically, forming a nipplelike apical end that are lacking in H. hera and H. limae.
Description.—Head: Vertex and frontoclypeus pale brown. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margin of segment 2, inner surface pale brown. Antennal scape pale brown, pecten brown, flagellum brownish gray. Proboscis pale brown.
Thorax: Tegula with basal 2/3 brown, apical 1/3 pale brown; mesonotum with basal 1/3 brown, apical 2/3 pale brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing (Fig. 366): Length 3.8–4.9 mm (n = 7), pale brown intermixed with brown scales; basal 1/3 pale brown except costa brown; submedian fascia complete or incomplete; cell with three spots, one near middle, two on apical end along crossvein; marginal spots present. Undersurface brown. Venation (Fig. 31) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases; CuA1 straight, CuA2 broadly curved. Hindwing: Translucent pale brown. Venation (Fig. 31) with cubitus 4-branched with M2 arising from distoposterior part of cell and M3 and CuA1 branching near 1/2.
Abdomen: Male genitalia (Figs. 159–160): Uncus narrowed from widened base, downcurved, narrowly rounded apically, setose, shorter than width of anal opening. Gnathos, narrow ring, confluent with tegumen, ventroposterior margin narrowly emarginate mesially. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part basally protracted inwardly, gradually widened beyond base, slightly narrowing apically, forming inwardly curved spinelike process; process setose on outer surface, planate on inner surface; ventral margin sparsely setose, slightly upturned beyond middle, narrowing to near base of setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process broadly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsal ridge of proximal flange; flange ellipsoid, microtrichiae throughout except, setose along ventral margin; margin mostly entire. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus about as long as valva; phallus straight, sclerite of phallus slightly curved at 1/4; anellus with widened base, constricted subapically, forming nipplelike apical end, and bearing two setal clusters on midregion. Female Genitalia: Unknown.

Distribution (Map 30). Hypatopa arxcis is known from two collecting sites in south-central Costa Rica along the Pacific coastline near the mouth of the Golfo de Nicoya.
Etymology. The specific epithet arxcis is derived from the Latin arx meaning, fortress, citadel, or stronghold.
