Glyphidocera minarum , new species

(Figs. 111–113, 324, Map 21 )

Diagnosis.— Glyphidocera minarum is most similar to G. plumae but differs from the latter by having a narrower base of the digitate process of the valva, a wider valval cucullus, and a larger apical cornutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus pale yellow; labial palpus with outer surface brown intermixed with few pale­yellow scales, segment II with pale­yellow scales to near apical margin; inner margin pale yellow intermixed with few brown scales; scape of antenna brown intermixed with pale­yellow scales, flagellum with alternating bands of brown and pale­brown scales; male 4th flagellomere distally dilated, protuberant and curved, forming a deep concavity opposite deeply excavated flagellomeres 5–6; proboscis pale yellow.

Thorax: Tegula and mesonotum brown. Legs brown with pale­yellow scales to apical margins of all segments and tarsomeres. Forewing (Fig. 324): Length 6.9 mm (n = 1), pale brown intermixed with few brown scales [most specimens are slightly rubbed]. Undersurface brown. Hindwing: Elongate pale­yellow scales except, with brown scales between basal half of Rs and anterior part of cell.

Abdomen (Fig. 111): Male with 4 transverse, irregular rows of sex scales on intersegmental areas between terga 2–3 and terga 3–4. Sex scales between terga 2–3 about of equal size as sex scales between terga 3–4.

Male Genitalia (Figs. 112–113): Uncus elongate, wide at base, slightly constricted at 1/ 3, laterally rounded apically, apex attenuate and setose; gnathos sparsely setose, protuberant, wide basally, abruptly narrowed, forming a knoblike, apical process; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a wide base, fusing medially and broadly from posteroventral margin to base of uncus; valva nearly straight from a shallow depression slightly beyond a slanted, basal, digitate process to apical furca; furca falcate, with a wide base; sacculus twisted apically, constricting valva before midlength, widening distoventrally, forming an elongate and broadly widened cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing an elongate, conical, apical cornutus; cornutus abruptly dilated basally, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 21 ): Glyphidocera minarum is known from one collecting site in north­central Costa Rica, north of San José.

Etymology: The species epithet minarum is derived from the Latin “minarus,” meaning threats.
