Glyphidocera advenae , new species

(Figs. 21–23, 294, Map 4 )

Diagnosis.— Relationships between Glyphidocera advenae and its congeners are difficult to determine because of the unique combination of features it possesses that include the absence of abdominal sex scales in the male, a small gnathos, a curved digitate process of the valva, a narrowly rounded costal furca of the valva, a slightly constricted apical part of the aedeagus, and an elongate apical cornutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus brown; outer surface of labial palpus brown intermixed with few pale­brown scales, inner surface pale brown intermixed with few brown scales; apical area of segment II and entire length of segment III with raised scales; scape of antenna and basal half of flagellum brown, distal half with alternating bands of brown and pale­brown scales; male 4th flagellomere dorsally protuberant and curved, forming a narrow and deep concavity opposite slightly excavated flagellomeres 5– 6; distal opening of concavity nearly closed by setiform scales on apex of 4th flagellomere; proboscis brown.

Thorax: Tegula and mesonotum brown intermixed with few pale­brown scales. Foreleg brown with pale­brown scales on apical margins of all segments and tarsomeres, pterothoracic legs slightly paler than foreleg. Forewing (Fig. 294): Length 6.0– 6.9 mm (n = 7), brown intermixed with pale­brown scales; cell and surrounding areas paler than marginal areas; cell with 2 large brown spots, 1 near middle, 1 near distal end [some specimens with spots faint or rubbed]. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 21): Male absent of sex scales on abdomen.

Male Genitalia (Figs. 22–23): Uncus elongate, broadly constricted above a widened base, parallelsided to an acuminate and narrowly bifurcate apex; gnathos short, narrow, protuberant, slightly upturned apically; tegumen slightly widened basally; dorsal strut with arms fused medially along posteroventral margin, forming a widened base, extending dorsally, narrowing to base of uncus; valva with costa broadly rounded from a shallow depression beyond basal digitate process to apical furca; furca short, acuminate; base of costa bearing an laterally curved digitate process; sacculus twisted apically, constricting valva before midlength, widening distoventrally, forming an elongate cucullus; cucullus membranous and setose, with a broadly rounded outer margin; aedeagus abruptly constricted subapically, forming a small, knoblike apex; vesica denticulate, bearing an elongate, conical, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.
