description: Hypatopa nox Adamski, new species
(Figs. 201–202, 387, Map 41)
Diagnosis.— Hypatopa nox is similar to H. dux in facies but differs from the latter by having a more protuberant median lobe of the ventroposterior margin of the gnathos; a wider apical process of the ventral part of the valva; and a shorter phallus. H. nox also has an outwardly curved digitate process of the dorsal part of the valva; an apically rounded, shallowly crenulate, margin of the proximal flange of the dorsal part of the valva; a sigmoidshaped sclerite of the phallus; and a broadly rounded apical margin of the anellus that are lacking in H. dux.
Description.—Head: Scales on vertex and frontoclypeus brownish gray tipped with pale brownish gray. Outer surface of labial palpus brown intermixed with pale-brown scales, inner surface paler. Antennal scape and pecten brownish gray, flagellum gray. Proboscis pale brownish gray.
Thorax: Tegula and mesonotum grayish brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing (Fig. 387): Length 5.8–6.1 mm (n = 6), pale brown intermixed with brown scales; cell with three spots, one near middle, two on apical end along crossvein; marginal spots faint or absent. Undersurface brown. Hindwing: Translucent pale brown.
Abdomen: Male genitalia (Figs. 201–202): Uncus gradually narrowed from wide base, acutely curved and narrowly rounded apically, sparsely setose, longer than width of anal opening. Gnathos narrow, anteriorly directed band, confluent with tegumen; ventroposterior margin narrowly emarginate. Sockets of tergal setae not extending to midlength of tegumen. Valva divided; ventral part basally truncate, angular near middle, abruptly narrowed apically, forming large, inwardly curved, apical process; process, setose on outer surface, planate on inner surface, ventral margin setose from angular part to margin, setose lobe at base of apical process; dorsal part with apical portion of costa extending dorsolaterally, forming setose digitate process; process broadly recurrent, shorter than apical process on ventral part; basal ridge of digitate process setose, extending ventrally fusing with dorsolateral ridge of proximal flange; flange elongate, broadly rounded apically, sparsely spinulate on basal 1/2, densely spiculate and sparsely setose on apical 1/2; margin shallowly crenulate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, sclerite of phallus sigmoid-shaped; anellus gradually narrowed from wide base, broadly rounded apically, setose on basal 1/2. Female Genitalia: Unknown.
