Glyphidocera spathae , new species

(Figs. 270–272, 377, Map 49 )

Diagnosis.— Glyphidocera spathae , G. s c u t i c a e, and G. c o t i s share abdominal sex scales between terga 2–3 in male, divergent costal furcae of the valva, and presence of several spinelike cornuti on the vesica of the aedeagus. G. spathae differs from the latter two species by having a setose gnathos, and dorsal strut of the tegumen with the arms constricted at midlength between the base of posteroventral margin and the base of uncus.

Description.— Head: Scales on vertex and frontoclypeus brown tipped with grayish yellow; outer surface of labial palpus dark brown intermixed with few grayish­yellow scales along apical margins of segments I–II; outer surface pale grayish yellow intermixed with few dark­brown scales; scape of antenna dark brown intermixed with few grayishyellow scales, flagellum with alternating bands of brown and grayish­yellow scales; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6 [setiform scales associated with 4th flagellomere missing]; proboscis pale grayish yellow.

Thorax: Tegula and mesonotum with brown scales tipped with pale grayish yellow. Legs dark brown intermixed with few pale grayish­yellow scales along apical margins of all segments and tarsomeres. Forewing (Fig. 377): Length 6.0– 6.3 mm (n = 2), grayish yellow intermixed with brown and dark­brown scales; costal margin dark brown intermixed with grayish­yellow scales; cell with 2 dark­brown, oblique spots, 1 spot near middle, 1 spot near distal end; marginal spots fused. Undersurface brown. Hindwing: Gray.

Abdomen (Fig. 270): Male with 5 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3. Anterior row of sex scales appear about ½ the size as the posterior 4 rows of sex scales.

Male Genitalia (Figs. 271–272): Uncus elongate, wide at base, broadly constricted near 1/3, widened subapically, apex acuminate and setose; gnathos protuberant, setose, wide throughout length, apically upturned and densely setose; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing basally from a wide base, extending dorsally, gradually widening to base of uncus; costa of valva nearly straight from shallow depression beyond a slanted, basal, digitate process to apex; apex bifurcate; furcae slightly divergent, ventral furca slightly longer than dorsal furca; sacculus twisted apically slightly beyond midlength, constricting valva, forming a broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many spinelike cornuti, bearing a large, crescent­shaped, apical cornutus; cornutus with one side shortened near midlength, exposing a large, hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 49 ): Glyphidocera spathae is known from two collecting sites in north­central Costa Rica, north of the Cordillera Central.

Etymology: The species epithet spathae is derived from the Latin “spatha,” meaning spatula.
