Hypatopa cotis Adamski , new species

( Figs. 145–146 , 359 , Map 27)

Diagnosis.— Hypatopa cotis possesses the following unique combination of features that includes: a lateral part of ventroposterior margin of gnathos broadly emarginate with the median part produced posteriorly, forming a large, narrowly notched lobe; a subquadrate proximal flange with a deeply serrate ventral and lateral margins; and a ventral margin of the ventral part of the valva bearing a dorsally curved spinelike process and a compact cluster of hairlike setae at base. This combination of character states differentiates it from all other congeners.

Description.—Head: Vertex and frontoclypeus pale brown. Outer surface of labial palpus pale brown intermixed with few brown scales on segments 1–2, terminal segment brown; inner surface of labial palpus pale brown. Antenna pale brown. Proboscis pale brown.

Thorax: Tegula brown on basal 1/3, pale brown on apical 2/3; mesonotum brown on basal 1/5, pale brown on apical 4/5. Foreleg brown intermixed with pale-brown scales near midtibia and along apical margins of tibia and tarsomeres [many scales missing]. Forewing ( Fig. 359 ): Length 4.5 mm (n = 1), pale brown intermixed with white and few brownish-orange scales; submedian fascia faint; cell with three faint, brown spots, one near middle, two on apical end along crossvein. Undersurface brown. Hindwing: Translucent pale brown gradually darkening to apex.

Abdomen: Male genitalia ( Figs. 145–146 ): Uncus narrowed from widened base, slightly constricted subapically, forming slightly enlarged apical part, slightly downcurved, sparsely setose, shorter than width of anal opening. Gnathos wide, laterally emarginate, confluent with tegumen, median part of ventroposterior margin produced posteriorly, forming large, narrowly notched median lobe. Tergal setae absent. Valva divided; ventral part widened mesially from narrowly rounded base, gradually narrowed apically, forming elongate, inwardly curved, spinelike process; process cylindrical, setose on basal 1/2 of outer surface; ventral margin entire, setose from midlength, with setose ridge at base of spinelike process; dorsal part with apical portion of costa supplanted by narrow basal articulation, fusing with dorsolaterally extending, setose, digitate process; basal ridge of digitate process extended ventrally fusing with dorsolateral ridge of proximal flange; flange subquadrate, spinulate, with serrate lateral and ventral margins; ventral margin bearing dorsally curved spinelike process with compact cluster of hairlike setae at base. Juxta divided. Vinculum semicircular. Phallus and sclerite of phallus longer than valva; phallus straight, sclerite of phallus singly coiled; anellus wide, parallelsided, broadly rounded apically, setose near middle. Female Genitalia: Unknown.

Distribution (Map 27). Hypatopa cotis is known from one collecting site on the Pacific coastline near the mouth of the Golfo de Nicoya.

Etymology. The specific epithet cotis is derived from the Latin cos meaning, a hard flint stone.
