Glyphidocera fabulae , new species

(Figs. 243–245, 368, Map 44 )

Diagnosis.— Glyphidocera fabulae , G. sapphiri , and G. arenae share abdominal sex scales between terga 2–3 in male, an elongate valval cucullus, and an elongate and narrow apical cornutus within the vesica of the aedeagus. G. fabulae can be distinguished from those two species by having an abdomen with more rows of sex scales between terga 2–3 in male, a wider gnathos, a wider base of the dorsal strut of the tegumen, a wider valval cucullus, and a large, upturned dorsal furca of the valval costa.

Description.— Head: Scales on vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus with segment I and basal half of segment II brown, distal half of segment II and segment III pale brown intermixed with few brown scales; inner surface pale brown intermixed with few brown scales; scape of antenna brown intermixed with few pale­brown scales, flagellum with alternating bands of pale brown and 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 are missing]; proboscis pale brown.

Thorax: Tegula and mesonotum brown. Legs pale brown intermixed with few brown scales; a pale banding appears near distal margins of all segments and tarsomeres. Forewing (Fig. 368): Length 6.9–7.0 mm (n = 2), brown intermixed with brown scales tipped with pale brown; cell with 2 large, faint, brown spots, 1 spot near middle, 1 spot near distal end. Undersurface brown intermixed with pale­brown scales along costal margin. Hindwing: Brown.

Abdomen (Fig. 243): Male with 4 transverse rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 244–245): Uncus elongate, wide at base, broadly constricted near 1/3, near parallelsided apically, apex acuminate and setose; gnathos setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a wide base, extending dorsally, widely to base of uncus; costa of valva shallowly emarginate broadly from a shallow depression beyond a basal, digitate process and a broadly upturned dorsal furca; apex bifurcate, each furca widely divergent; dorsal furca about 3 times larger than ventral furca; sacculus twisted apically, constricting valva slightly beyond midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many stout, cornuti, bearing an elongate, conical, apical cornutus; cornutus with one side shortened near 1/3 length, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 44 ): Glyphidocera fabulae is known from two collecting sites in Costa Rica; one in the north­western part of Costa Rica south­west of the Cordillera de Guanacaste, and one site in the south­central part of the country south of the Cordillera Central.

Etymology: The species epithet fabulae is derived from the Latin “fabula,” meaning story.
