Glyphidocera plebis, new species

(Figs. 96–98, 319, Map 18)

Diagnosis.— Glyphidocera plebis is most similar to G. a r a e but differs from the latter by having with larger sex scales between abdominal terga 2–3 in male, a tegumen with a less developed dorsal strut, a narrower cucullus of the valva, and a longer apical furca of the valval costa.

Description.— Head: Vertex and frontoclypeus brownish orange; outer surface of labial palpus dark brown intermixed with brownish­orange scales, segment II with brownish­orange scales along apical margin; inner surface pale brownish intermixed with few dark­brown scales; scape of antenna brownish orange intermixed with few dark­brown scales, flagellum with alternating bands of pale brownish­orange and brown scales; male 4 th flagellomere dorsally protuberant and curved, forming a shallow concavity opposite slightly excavated flagellomeres 5–6 [setiform scales closing concavity on apex of protuberance of 4 th flagellomere missing]; proboscis pale brownish orange.

Thorax: Tegula and mesonotum brownish orange or brownish orange intermixed with dark­brown scales. Legs brownish orange intermixed with dark­brown scales, and brownish­orange scales along apical margin of all segments and tarsomeres. Forewing (Fig. 319): Length 5.0– 5.8 mm (n = 10), brownish orange intermixed with few dark­brown scales; cell with 3 dark­brown spots, 1 near middle, 2 near distal end; posterior spot near distal end slightly basal to anterior spot; marginal spots present or absent. Undersurface brown except brownish orange along costa. Hindwing: Pale gray.

Abdomen (Fig. 96): Male with 4 transverse, irregular rows of large­sized sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 97–98): Uncus elongate, wide at base, broadly constricted near midlength, apex narrowly rounded; gnathos densely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially from posteroventral margin of tegumen, atrophied dorsally near midway from base of uncus; costa of valva broadly emarginate from a shallow depression beyond a slanted, digitate process to apical furca; furca acuminate, upturned, slightly longer than width of distal valva; sacculus twisted apically slightly before midlength, constricting valva, widening distoventrally, forming an elongate and narrow cucullus; cucullus membranous and setose; vesica denticulate, bearing an elongate, hornlike, apical cornutus; cornutus shortened near 2 / 3 length, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution (Map 18): Glyphidocera plebis is known from collecting sites along coastal south­central Costa Rica.

Etymology: The species epithet plebis is derived from the Latin “plebes,” meaning the multitude.
