Glyphidocera nubis , new species

(Figs. 9–11, 290, Map 2 )

Diagnosis.— Glyphidocera nubis is similar to G. ferae but differs from the latter in having a narrower and shorter uncus, a more densely setose gnathos, a slightly curved digitate process of the valva, a narrower distal part of the valva, and more sex scales between abdominal terga 2–3 and terga 3–4 in the male.

Description.— Head: Vertex and frontoclypeus grayish brown; outer surface of segments I–II of labial palpus grayish brown intermixed with pale grayish­yellow scales to apical margins, segment III brown intermixed with pale grayish­brown scales apically; inner surface of segments I–II pale grayish yellow intermixed with few grayish­brown scales, segment III brown intermixed with few pale grayish­yellow scales; scape of antenna brown intermixed with few pale grayish­yellow scales, flagellum with alternating bands of brown and pale­brown scales; male 4th 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 4th flagellomere; proboscis pale grayish yellow.

Thorax: Tegula and mesonotum brown intermixed with few pale­brown scales. Legs brown intermixed with pale grayish­yellow scales on apical margins of all segments and tarsomeres. Forewing (Fig. 290): Length 5.8 mm (n = 1), brown intermixed with few slightly paler scales. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 9): Male with 6 transverse, irregular rows of sex scales on intersegmental area between terga 2–3 and 4 transverse, irregular rows of sex scales on intersegmental area between terga 3–4. Sex scales between terga 2–3 slightly larger and more numerous than sex scales between terga 3–4.

Male Genitalia (Figs. 10–11): Uncus elongate, abruptly constricted slightly beyond base, nearly parallelsided to a narrowly rounded and setose apex; gnathos densely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing midway between posteroventral margin and base of uncus, arms diverging dorsally from middle; costa of valva slightly rounded from shallow depression slightly beyond base of digitate process to a rounded apex; sacculus twisted apically, constricting valva at 2/3 length, widening distoventrally, forming a moderately elongate cucullus; cucullus membranous and setose, with a nearly truncate outer margin; vesica of aedeagus with rounded denticles, bearing an moderately elongate, conical, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 2 ): Glyphidocera nubis is known from one collecting site near Río Tárcoles at the mouth of Golfo de Nicoya along the Pacific coast.

Etymology: The species epithet nubis is derived from the Latin “nubes,” meaning clouds.
