(Figs. 135–137, 332, Map 25 )

Diagnosis.— Glyphidocera gazae can be distinguished from its congeners by a unique combination of features including the male abdomen lacking sex scales, gnathos small, dorsal strut of tegumen widened basally and narrowed gradually to base of uncus, furcae of valval costa widened, and cucullus slightly upturned from valval constriction near distal end.

Description. Head: Scales on vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus brown intermixed with pale­brown scales to margin of segment II, segment III brown; inner margin pale brown intermixed with few brown scales; scape of antenna brown intermixed with few pale­brown scales, flagellum with alternating bands of pale­brown and brown scales; male 4th flagellomere distally dilated, protuberant and curved, forming a deep concavity opposite deeply excavated flagellomeres 5–6; proboscis brown.

Thorax: Tegula and mesonotum brown. Legs brown intermixed with few pale­brown scales to near apical margins of all segments and tarsomeres. Forewing (Fig. 332): Length 6.0–7.0 mm (n = 6), pale brown intermixed with brown scales; cell with a small brown spot near distal end. Undersurface brown. Hindwing: Pale yellow intermixed with few pale grayish­brown scales.

Abdomen (Fig. 135): Male with sex scales absent.

Male Genitalia (Figs. 136–137): Uncus elongate, wide at base, broadly constricted near 1/3, broadly rounded distally, apex acuminate; gnathos protuberant, wide basally, gradually narrowed distally, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a widened base, extending dorsally to base of uncus; costa of valva slightly emarginate broadly from a shallow depression beyond a basal digitate process to a slightly upturned dorsal furca; apex bifurcate, each furca about equal in size, divergent; base of costa bearing a slanted, subapically downcurved digitate process; sacculus twisted apically, constricting valva near midlength, slightly widening distoventrally forming an elongate and shallowly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing an elongate, apical cornutus; cornutus with one side shortened near base, slightly exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 25 ): Glyphidocera gazae is known from two collecting sites in Costa Rica; one site in the north­west along the Cordillera de Guanacaste and one site in the north­central part of the country, north of the Cordillera Central.

Etymology: The specific epithet gazae is derived from the Latin “gaza,” meaning royal treasure.
