Diagnosis.— Glyphidocera cenulae is most similar to G. laricae but differs from the latter by having a larger gnathos, a larger digitate process of the valva, subequal costal furcae of the valva, a wider cucullus, and a smaller apical cornutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus grayish brown; labial palpus with outer surface grayish brown intermixed with few pale brownish­yellow and dark­brown scales, inner surface pale brownish yellow; scape of antenna grayish brown intermixed with few pale brownish­yellow scales, flagellum with alternating bands of pale grayish­brown and brownish­yellow scales; male 4 th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4 th flagellomere; proboscis pale grayish brown.

Thorax: Tegula and mesonotum grayish brown. Legs pale grayish brown intermixed with grayish­brown scales, tarsomeres with pale brownish­yellow scales to near apical margin. Forewing (Fig. 349): Length 7.9 mm (n = 1), grayish brown intermixed with pale grayish­brown scales, with no characteristic markings. Undersurface pale grayish brown. Hindwing: Pale grayish brown intermixed with few grayish­brown and pale brownish­yellow scales.

Abdomen (Fig. 186): Male with two pairs of sex scale clusters on intersegmental membrane between terga 2–3 and terga 3–4, each cluster with 3 transverse, irregular rows of sex scales; scales between terga 2–3 appear slightly smaller than sex scales between terga 3–4.

Male Genitalia (Figs. 187–188): Uncus elongate, wide at base, broadly constricted near 1 / 4, broadly widened apically, apex attenuate; gnathos protuberant, narrow throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent but separate to base of uncus; costa of valva nearly straight from a shallow depression beyond a basal, digitate process to an upturned dorsal furca; apex widely bifurcate, dorsal furca twice as wide as ventral furca; base of costa bearing a slanted, digitate process, abruptly curved apically; sacculus twisted apically, constricting valva slightly beyond middle, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with microdenticles, and bearing and a small, conical, apical cornutus.

Female Genitalia: Unknown.

Distribution (Map 34): Glyphidocera cenulae is know from one collecting site in northern Costa Rica near the north­western coast of Limón.

Etymology: The species epithet cenulae is derived from the Latin “cenula,” meaning a small dinner.
