Diagnosis.— Glyphidocera ranae is most similar to G. ancillae; it can be distinguished from the latter by having a larger gnathos, a larger digitate process of the valva, a slightly recurved dorsal furca of the valval costa, and the vesica of aedeagus with an apical cornutus with a bulbous base.

Description.— Head: Vertex and frontoclypeus brown; outer surface of labial palpus brown intermixed with few pale­brown scales to apical margin of segment II, inner surface pale brown intermixed with few brown scales; scape of antenna brown, flagellum with alternating bands of pale brown and brown scales; male 4 th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a digitate protuberance of 4 th flagellomere; proboscis pale brown.

Thorax: Tegula and mesonotum brown. Legs brown intermixed with pale­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 371): Length 5.9– 6.2 mm (n = 7), pale brown intermixed with pale grayish­orange, brown, and few darkbrown scales; cell with 2 brown spots, 1 large spot near middle, 1 small spot near distal end [spots are faint in some specimens]. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 252): Male with 3 transverse rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 253–254): Uncus elongate, wide at base, broadly constricted at 1 / 3, slightly widened apically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from a widened base from posteroventral margin to base of uncus; costa of valva slightly sloped dorsally from shallow depression beyond a slanted, basal, digitate process to an upturned dorsal furca; apex widely bifurcate from a narrowly rounded inner margin; dorsal furca about 3 times larger than ventral furca; sacculus twisted apically constricting valva near midlength, widening distoventrally forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a large, conical, apical cornutus; curnutus with a bulbous base, with one side slightly shorter, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution (Map 46): Glyphidocera ranae is known from three collecting sites in Costa Rica, from the north­western part along the Cordillera Guanacaste, east to the northcentral part of the country along the Caribbean Coast, south­east to a coastal site along the Pacific Ocean.

Etymology: The species epithet ranae is derived from the Latin word for frog ­ rana.
