Glyphidocera paenulae , new species

(Figs. 12–14, 291, Map 2 )

Diagnosis.— Relationships between Glyphidocera paenulae and other species of Glyphidocera are difficult to determine because of the several unique features possessed by the former that include a short digitate process of the valva, a toothlike process on the distal 1/ 3 of valva, an angular distal part of valva, and large sex scales between abdominal terga 2– 3 and terga 3–4 in the male.

Description.— Head: Vertex and frontoclypeus pale grayish orange; outer margin of labial palpus pale grayish orange intermixed with few dark­brown scales, inner surface as above but paler; scape of antenna pale grayish orange intermixed with few dark­brown scales, flagellum with alternating bands of pale grayish­orange and brown scales; male 4th flagellomere not protuberant, 5th and 6th flagellomeres slightly excavated; proboscis pale grayish orange intermixed with few dark­brown scales.

Thorax: Tegula and mesonotum pale grayish orange intermixed with few dark­brown scales. Legs with all segments pale grayish orange intermixed with few dark­brown scales, tarsomeres dark brown intermixed with pale grayish­orange scales to apical margins. Forewing (Fig. 291): Length 7.2–7.5 mm (n = 2), pale grayish orange intermixed with few dark­brown scales, with several small, dark­brown spots; 1 on base of costa, 2 on base near middle of cell between Radius and Cubitus, 2 near distal end of cell near to and parallel with crossvein, and 4 marginal spots. Undersurface pale grayish orange. Hindwing: Pale grayish brown basally, gradually darkening to apex.

Abdomen (Fig. 12): Male with 4 transverse, irregular rows of large sex scales on intersegmental areas between terga 2–3 and terga 3–4.

Male Genitalia (Figs. 13–14): Uncus elongate, wide, slightly constricted beyond base, parallelsided to a slightly rounded apex; gnathos protuberant, wide throughout length, apex rounded and upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially, narrow throughout length and extending dorsally from posteroventral margin to the base of uncus; costa of valva gradually downturned broadly from a shallow depression slightly beyond a stout digitate process to a slightly rounded apex; costa with a recurrent, toothlike process near 2/3 length; sacculus twisted apically, constructing valva narrowly, widening distoventrally, forming an angular cucullus; cucullus membranous and setose, with a slanted outer margin; vesica of aedeagus with an elongate apical cornutus and several small, thin cornuti.

Female Genitalia: Unknown.

Paratype: 1 ɗ, Same label data as above except, “ 15 Abril 1996, L/05/214”, “CRI002, 060221 ”, “Slide No. 917.”

Distribution ( Map 2 ): Glyphidocera paenulae is known from a single collecting site in north­central Costa Rica.

Etymology: The species epithet paenulae is derived from the Latin “paenula,” meaning a traveling cloak.
