Glyphidocera scuticae , new species

(Figs. 273–275, 378, Map 50 )

Diagnosis.— Glyphidocera scuticae , G. s p a t h 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. scuticae can be distinguished from the latter two by having an abdomen with more sex scales between terga 2–3 in male, a dorsal strut of the tegumen with a small and elongate sinus above the base, and the costal furcae of the valva more divergent.

Description.— Head: Vertex and frontoclypeus with grayish­brown scales, each tipped with pale grayish brown; outer surface of labial palpus brown intermixed with pale grayish­brown scales, inner surface pale grayish brown intermixed with few brown scales; scape of antenna brown intermixed with pale grayish­brown scales, flagellum with alternating bands of brown and pale grayish­brown scales; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6 [many setiforn scales associated with 4th flagellomere missing]; proboscis pale grayish brown intermixed with brown scales.

Thorax: Tegula and mesonotum with brown scales tipped with pale grayish brown. Legs brown intermixed with few pale grayish­brown scales along apical margins of all segments and tarsomeres. Forewing (Fig. 378): Length 6.8 mm (n = 1), pale grayishbrown scales intermixed with brown scales; mostly brown scales along costa and distal 1/ 3; cell with a linear streak near distal end along crossvein. Undersurface brown. Hindwing: Pale brown.

Abdomen (Fig. 273): Male with 3 transverse, irregular rows of scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 274–275): Uncus elongate, wide at base, broadly constricted near midlength, gradually widened apically, apex acuminate and setose; gnathos protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent fusing medially along posteroventral margin, extending dorsally to base of uncus, with an elliptical sinus within basal part; costa of valva slightly upturned from a shallow depression beyond a slanted, basal, digitate process to dorsal furca; apex widely bifurcate; furcae divergent, each furca about equal in size; base of costa with an narrowly elongate, straight, digitate process; sacculus twisted apically, constricting valva slightly beyond midlength, forming a broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many spinelike cornuti, and bearing a large, crescent­shaped, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “Sector Cerro Cocori, F[in]ca de E. Rojas, Prov[incia] Limón, COSTA RICA, E. Rojas, Mar. 1991, L­N­286000, 567500”, “INBio: COSTA RICA: CRI000, 181435” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 713” [yellow label].

Distribution ( Map 50 ): Glyphidocera scuticae is known from one collecting site in the north­western part of Limón in northern Costa Rica.

Etymology: The species epithet scuticae is derived from the Latin “scutica,” meaning whip.
