( Figs. 2 , 59–60 , 316 , Map 3)

Diagnosis.— Hallicis clavicula is similar to H. bisetosellus in facies but differs from the latter by having a smaller uncus; an entire posterioventral margin of the gnathos; and an acutely curved apical process of the ventral part of the valva. H. clavicula also has an elongate, setose lobe overlying the base of the costa, originating from the inner surface of the dorsal part of the valva; a large, laterally directed, upturned lobe with a spinelike seta originating from the base of the dorsal part of the valva; and a platelike juxta that are lacking in H. bisetosellus .

Description.—Head: Vertex, frontoclypeus brown. Outer surface of labial palpus dark brown intermixed with few pale-brown scales, with pale-brown scales along apical margin of segments 1–2; terminal segment dark brown basally, pale brown apically; inner surface with same pattern but paler. Antennal scape and pecten pale brown, flagellum brownish gray; first flagellomere unmodified in male. Proboscis brown.

Thorax: Tegula dark brown on basal 1/2, pale brown on apical 1/2; mesonotum pale brown. Legs dark brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 316 ): Length 4.6 – 5.7 mm (n = 6), brown intermixed with pale-brown scales and dark-brown scales; area from base to submedian fascia pale brown, costa and anal margin dark brown; basal 1/3 pale brown, apical 2/3 brown; submedian fascia complete or incomplete, faint, with few dark-brown scales; cell with three dark-brown spots, one spot near middle, two spots near apical end along crossvein; marginal spots brown. Undersurface brown. Venation ( Fig. 2 ) with CuA1 and M3 arising from a common point on distoposterior part of cell and CuA2 arising about 1/3 length from distoposterior part of cell. Hindwing: Translucent pale brown, gradually darkening to apex. Venation ( Fig. 2 ) with cubitus 4-branched with M2, M3, with CuA1 arising from part of cubitus extending slightly beyond cell; M2 stalked slightly basal to branching M3 and CuA1.

Abdomen: Male genitalia ( Figs. 59–60 ): Uncus wide basally, abruptly constricted near middle, forming sparsely setose apical lobe, shorter than width of anal opening. Dorsal strut absent. Gnathos, a thin band, confluent with tegumen; posteroventral margin entire. Sockets of tergal setae not extending beyond 1/2 length of tegumen. Distance between articulations of tegumen and vinculum shorter than length of valva. Valva divided; ventral part of valva broadly rounded basally, apically narrowed, forming inwardly curved spinelike process; process acutely curved near midlength, with planate inner surface; small setose marginal ridge near base of apical process; dorsal part with apical portion of costa developed distolaterally into sparsely setose, digitate process; inner surface with elongate, setose lobe overlying base of costa; basilateral part developed into upturned lobe bearing large apical seta, proximal flange absent. Juxta subtrapezoidal. Phallus and sclerite of phallus acutely curved from middle; anellus gradually narrowed from base, rounded apically, setose throughout most of length. Female Genitalia: Unknown.

Distribution (Map 3). Hallicis clavicula is known from two collecting sites along the western most part of the Cordillera de Guanacaste in northwestern Costa Rica and a single collecting site along the southwestern part of the Cordillera de Tilarán in the west-central part of the country.

Etymology. The specific epithet is derived from the Latin clavicula meaning a tendril of a vine, and refers to the tapering digitate process originating from the base of the valva of the genitalia, which terminates with a single seta.
