Glyphidocera placentae , new species

(Figs. 198–200, 353, Map 36 View MAP 36 )

Diagnosis.— Glyphidocera placentae can be distinguished from its congeners by a unique combination of features that includes sex scales between terga 2–3 of the male abdomen, gnathos densely setose, dorsal strut of tegumen with tergal arms forming a short medial sinus between posteroventral margin and base of uncus, and costal furcae of valva nearly equal in size.

Description.— Head: Vertex and frontoclypeus pale brown; labial palpus with outer surface pale brown intermixed with few brown scales, inner surface pale yellowish brown intermixed with few pale­brown scales; scape of antenna pale brown intermixed with few brown scales, flagellum with alternating bands of brown and pale­brown scales; male 4th flagellomere dorsally protuberant and curved, forming a shallow concavity opposite slightly excavated flagellomeres 5–6 [setiform scales of apex of protuberance of 4th flagellomere missing]; proboscis pale brown.

Thorax: Tegula and mesonotum pale brown. Legs pale brown intermixed with few brown scales, pale yellowish­brown along apical margin of all segments and tarsomeres. Forewing (Fig. 353): Length 6.0 mm (n = 1), pale yellowish brown intermixed with pale brownish­orange and few brown scales; cell with 4 faint brown spots; 2 spots in diagonal line near distal end, 1 spot near midlength on Radius, and 1 spot near base. Undersurface pale brown. Hindwing (Fig. 00): Pale brown.

Abdomen (Fig. 198): Male with 3 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 199–200): Uncus elongate, wide at base, broadly constricted near 1/3, slightly rounded apically, apex narrowly rounded and setose; gnathos densely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent basally and dorsally, forming an elliptical­shaped sinus beneath base of uncus; valva with costa nearly straight from a shallow depression beyond a basal, digitate process to dorsal furca; apex widely bifurcate, inner margin between furcae broadly rounded; furcae divergent, about equal in size; base of costa bearing a stalked, slanted, digitate process with a wide base; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many stout, conical cornuti, and bearing an elongate, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 36 View MAP 36 ): Glyphidocera placentae is known from a single collecting site on the Osa Peninsula in south­eastern Costa Rica.

Etymology: The species epithet placentae is derived from the Latin “placenta,” meaning a small cake.
