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.

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.
