Glyphidocera glaebae , new species

(Figs. 165–167, 342, Map 29 )

Diagnosis.— Glyphidocera glaebae is most similar to G. p i l a e but differs by having a longer gnathos, costal furcae of valva more narrowly separate, and dorsal furca of valval costa oriented laterally.

Description.— Head: Vertex and frontoclypeus pale brownish yellow; outer surface of labial palpus brown intermixed with pale brownish­yellow scales to near apical margin of segment II, inner surface pale brownish yellow intermixed with few brown scales; scape of antenna pale brownish yellow intermixed with few brown scales, flagellum with alternating bands of pale brownish­yellow and brown scales; male 4th flagellum 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 4th flagellomere; proboscis pale brownish yellow.

Thorax: Tegula and mesonotum pale brownish yellow intermixed with few brown scales. Legs brown intermixed with pale brown, and pale brownish­yellow scales to apical margins of all segments and tarsomeres [some specimens with banding on legs absent]. Forewing (Fig. 342): Length 6.5–7.0 mm (n = 10), brownish yellow intermixed with few brown scales; cell with 2 small spots, 1 spot near middle, 1 spot near distal end [some specimens with a small basimedian spot, and marginal spots present or absent]. Undersurface pale brown intermixed with pale brownish­yellow scales along costa. Hindwing: Pale brownish yellow.

Abdomen (Fig. 165): Male with one short row of sex scales along medial area of intersegmental membrane between terga 2–3, and with 3 transverse, irregular rows of sex scales on intersegmental membrane between terga 3–4.

Male Genitalia (Figs. 166–167): Uncus elongate, wide at base, broadly constricted near ½ length, broadly rounded apically, apex narrowly rounded and setose; gnathos protuberant, slightly narrowed throughout length, rounded apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from a wide base, gradually widening dorsally to base of uncus; costa of valva nearly straight from a shallow depression beyond a basal digitate process to a slightly raised dorsal furca; apex bifurcate, dorsal furca 3–4 times larger than ventral furca; sacculus twisted apically near midlength, widening distoventrally, forming an elongate and broadly rounded, narrow cucullus; cucullus membranous and setose; vesica of aedeagus sparsely denticulate, bearing a large, conical, apical cornutus; cornutus with one side shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 29 ): Glyphidocera glaebae is known from two collecting sites in north­central Costa Rica, north of the Cordillera Central.

Etymology: The species epithet glaebae is derived from the Latin “glaeba,” meaning soil.
