Glyphidocera contionis , new species

(Figs. 144–146, 335, Map 26 )

Diagnosis.— Glyphidocera contionis is most similar to G. umbrae but differs from the latter by having a larger pair of costal furcae of the valva, costal furcae that are oriented dorsally, and a narrower valval cucullus.

Description.— Head: Vertex and upper frons grayish brown, lower frons pale gray; labial palpus with segments I–II grayish brown intermixed with few pale­yellow scales to near apical margin, segment III grayish brown; inner surface with segments I–II pale yellow, segment III grayish brown intermixed with few pale­yellow scales; scape of antenna pale yellow intermixed with few grayish­brown scales; scape of antenna pale yellow intermixed with few grayish­brown scales, flagellum with alternating bands of pale­yellow and grayish­brown scales; 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; proboscis pale yellow.

Thorax: Tegula and mesonotum grayish brown. Legs grayish brown intermixed with few pale­yellow scales to near apical margin of all segments and tarsomeres. Forewing (Fig. 335): Length 5.8 mm (n = 1), grayish brown intermixed with pale­yellow scales and few pale grayish­brown; a small pale­yellow spot near base; costa, cell, and outer marginal scales pale yellow. Undersurface pale grayish brown. Hindwing: Grayish brown.

Abdomen (Fig. 144): Male with 3 transverse, irregular rows of sex scales on intersegmental areas between terga 2–3 and terga 3–4. Sex scales between terga 2–3 slightly larger than sex scales between terga 3–4.

Male Genitalia (Figs. 145–146): Uncus elongate, wide at base, slightly constricted near 1/3, nearly parallelsided to a narrowly rounded apex; gnathos sparsely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing near 1/3 length between posteroventral margin and base of uncus, atrophied dorsally; valva with costa nearly straight from a basal digitate process to midlength, gradually sloped to an upturned dorsal furca; apex widely bifurcate with margin between furcae nearly U­shaped, furcae upturned, about equal in size, ventral furca slightly curved inwardly; base of costa with a slightly stalked, nearly straight, digitate process; sacculus twisted apically, constricting valva near midlength, slightly widening distoventrally, forming an elongate cucullus; cucullus membranous and setose, with outer margin broadly rounded; vesica of aedeagus with several small, stout, cornuti, and bearing a large, conical, apical cornutus; cornutus a bulbous basal part with a shortened side, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “Sector Cerro Cocori, F[in]ca de E. Rojas, 150 m, Prov[incia] Limón, COSTA RICA, E. Rojas, Ene. 1992, L­N­286000, 567500”, “INBio: COSTA RICA: CRI000, 333815” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 686” [yellow label].

Distribution ( Map 26 ): Glyphidocera contionis is known from one collecting site in the north­western part of Limón in northern Costa Rica.

Etymology: The species epithet contionis is derived from the Latin “contio,” meaning an assembly.
