Glyphidocera gemmae , new species

(Figs. 30–32, 303, Map 6 )

Diagnosis.— Glyphidocera gemmae is similar to G. eminetiae but differs from the latter by having a straight apical furca of the valval costa, a less angular distal part of the valva, and a larger apical cornutus of the aedeagal vesica

Description.— Head: Scales of vertex and frontoclypeus brown tipped with pale brown; scape pale brown, flagellum pale brown; male 4th flagellomere not protuberant, 5th and 6th flagellomeres slightly excavated; proboscis pale brown.

Thorax: Tegula and mesonotum pale brown. Legs brown intermixed with pale­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 303): Length 5.3– 5.8 mm (n = 2), costa and distal 1/3 brown intermixed with pale­brown scales; cell and surrounding areas of cell paler than marginal areas; cell with 2 brown spots, 1 near middle, 1 near distal end, CuP with a small brown spot slightly basal and posterior to midcell spot [one specimen with wing spots absent]. Undersurface pale brown. Hindwing: Pale brown.

Abdomen (Fig. 30): Male with 4 transverse, irregular rows of sex scales on intersegmental area between segments 2–3, and with two elliptical­shaped clusters of sex scales, formed by 3–4 short, irregular rows of scales, on intersegmental area between terga 3–4.

Male Genitalia (Figs. 31–32): Uncus elongate, broadly constricted above a widened base, broadly rounded medially, gradually tapering to an acuminate and setose apex; gnathos setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms fusing medially, dorsally atrophied; costa of valva nearly straight from a shallow depression beyond a slightly downturned, basal digitate process to apical furca; furca slightly upturned, nearly as long as width distal valva; sacculus twisted apically, constricting valva before midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a large, conical, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 6 ): Glyphidocera gemmae is known from two coastal collecting sites along the Pacific Ocean in south­eastern Costa Rica.

Etymology: The species epithet gemmae is derived from the Latin “gemma,” meaning jewel.
