Glyphidocera vestita Walsingham 1911

(Figs. 225–227, 362, Map 41 )

Glyphidocera vestita Walsingham, 1911: 112 ; Becker 1984: 41 (checklist).

Diagnosis.— Glyphidocera vestita is most similar to G. speculae but differs by having fewer rows of sex scales between terga 2–3 on the abdomen of the male, a tegumen that is wider basally, a narrower costal furcae of valva, a more protracted apicoventral margin of the valval cucullus, an apical cornutus with a bulbous base, and the presence of many spinelike cornuti on vesica of aedeagus.

Description.— Head: Scales on vertex and frontoclypeus brown tipped with pale brown; outer and inner surfaces of labial palpus brown intermixed with pale­brown scales to apical margin of segment II; scape of antenna brown intermixed with few pale­brown scales, flagellum with alternating bands of brown and pale­brown scales; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4th flagellomere; proboscis brown.

Thorax: Tegula and mesonotum with brown scales tipped with pale brown or brown. Legs brown intermixed with pale­brown to apical margins of all segments and tarsomeres. Forewing (Fig. 362): Length 5.5–6.1 mm (n = 14), brown intermixed with pale­brown scales and few brownish­yellow scales; cell and surrounding areas paler than marginal areas; cell with 2 small, faint spots, 1 spot near middle, 1 spot near distal end [rubbed specimens with spots faint or absent]. Undersurface brown. Hindwing: Pale brown.

Abdomen (Fig. 225): Male with 4 transverse rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 226–227): Uncus elongate, constricted near ½ length, broadly rounded and upturned apically, apex acuminate and setose; gnathos protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially, extending dorsally, gradually widening narrowly to base of uncus; costa of valva nearly straight from a shallow depression beyond a curved, basal, digitate process to an upturned dorsal furca; apex widely bifurcate, inner margin U­shaped; dorsal furca large, falcate, ventral furca extending slightly beyond outer margin of cucullus; sacculus twisted apically, constricting valva slightly before midlength, widening distoventrally forming an broadly rounded, slightly protracted cucullus; cucullus membranous and setose; vesica of aedeagus with many moderately large, spinelike cornuti, and bearing a large, conical, apical cornutus; cornutus bulbous basally, with one side shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 41 ): In Costa Rica, Glyphidocera vestita is known from north­western to north­central Costa Rica, south to the Pacific Coast from the Province of San José east to Puntarenas. G. vestita is also known from Panamá (Walsingham, 1911).
