Glyphidocera cotis , new species

(Figs. 276–278, 379, Map 50 )

Diagnosis.— Glyphidocera cotis , G. s c u t i c a e, and G. s p a t h a e share abdominal sex scales between terga 2–3 in male, a divergent costal furcae of the valva, and presence of several spinelike cornuti on the vesica of the aedeagus. G. c o t i s differs from the latter two species by having an abdomen with larger sex scales between terga 2–3 in male, an uncus with a wider base, dorsal strut of tegumen wider basally, digitate process of the valva wider basally, margin of valval costa broadly crenulate, and absence of an apical cornutus within the vesica of the aedeagus.

Description.— Head: Vertex and frontoclypeus pale yellow; outer surface of labial palpus with segments I–II brown intermixed with pale yellow along apical margins, segment III pale yellow intermixed with few brown scales; inner surface pale yellow; scape and basal flagellomeres 1–6 pale yellow, distal flagellomeres brown; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6 [many setiform scales associated with 4th flagellomere missing]; proboscis pale yellow.

Thorax: Tegula and mesonotum brown. Legs pale yellow intermixed with few brown scales, pale yellow along apical margins of all segments and tarsomeres. Forewing (Fig. 379): Length 4.3 mm (n = 1), brown intermixed with few grayish brown scales, with no characteristic markings. Undersurface brown. Hindwing: Pale gray.

Abdomen (Fig. 276): Male with 3 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 277–278): Uncus elongate, wide at base, slightly widened basally, parallelsided nearly entire length, gradually narrowed rounded apex; gnathos sparsely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a widened base, fusing about 2/3 length between posteroventral margin to base of uncus, dorsally atrophied; costa of valva broadly crenulate from a shallow depression beyond slanted, basal, digitate process to dorsal furca; apex widely bifurcate; furcae about equal in size, ventral furcae slightly wider than dorsal furca; base of costa bearing a stout, slanted, digitate process; sacculus twisted apically, constricting valva slightly beyond midlength, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many spinelike, cornuti.

Female Genitalia: Unknown.

Holotype, ɗ, “ COSTA RICA, Heredia, Est[ación] Biol[ógica] La Selva, 50–150 m, 10°26'N, 84°01'W, Apr. 1996, INBio­OET”, “ 24 Abril 1996, L/04/226”, “INBio: COSTA RICA: CRI002, 060925 ” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 902” [yellow label].

Distribution ( Map 50 ): Glyphidocera cotis is known from one collecting site in eastcentral Heredia in northern Costa Rica.

Etymology: The species epithet cotis is derived from the Latin “cos,” meaning whetstone.
