(Figs. 147–149, 336, Map 27 )

Diagnosis.— Glyphidocera umbrae is most similar to G. contionis but differs from the latter by having smaller costal furcae of valva, costal furcae oriented dorsolaterally, and a wider valval cucullus.

Description.— Head: Vertex brown; frontoclypeus grayish yellow; outer surface of labial palpus with segment I grayish yellow, basal half of segment II brown, distal half grayish brown, segment III brown; inner surface with segments I–II grayish yellow intermixed with few brown scales, segment III brown; scape of antenna grayish yellow intermixed with few brown scales, flagellum with alternating bands of grayish­yellow and brown scales; male with 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; proboscis pale grayish yellow.

Thorax: Tegula and mesonotum brown. Legs brown intermixed with pale grayish­yellow scales to apical margins of all segments and tarsomeres. Forewing (Fig. 336): Length 5.0– 5.2 mm (n = 2), brown intermixed with few dark­brown scales; cell with one large dark­brown spot near distal end. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 147): Male with 4 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3 and terga 3–4. Sex scales between terga 2–3 appear twice the size as those between terga 3–4.

Male Genitalia (Figs. 148–149): Uncus elongate, wide at base, broadly constricted near 1/3, nearly parallelsided apically, apex narrowly rounded; gnathos sparsely setose, protuberant, moderately widened throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from posterorventral margin, and slightly atrophied dorsally; costa of valva shallowly emarginate medially from a basal, digitate process to a slightly raised distal part; apex widely bifurcate, each furca parallel; dorsal furca about ½ size of ventral furca; margin between furcae U­shaped; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus sparsely denticulate, bearing a large, apical cornutus; cornutus with a bulbous base with one side shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 27 ): Glyphidocera umbrae is known from two collecting sites in Costa Rica; one site in north­central Costa Rica and one site in the coastal south­eastern part of the country, south of the Osa Peninsula.

Etymology: The species epithet umbrae is derived from the Latin “umbra,” meaning shade.
