Glyphidocera zophocrossa Meyrick, 1929

(Figs. 210–212, 357, Map 38 )

Glyphidocera zophocrossa Meyrick, 1929: 530 ; Becker, 1984: 41 (checklist).

Diagnosis.— Glyphidocera zophocrossa is most similar to G. guaroa from which it can be distinguished by having the dorsal strut of tegumen constricted near midlength and the dorsal furca of costal valva extending beyond the ventral furca.

Description.— Head: Vertex and frontoclypeus pale brownish yellow; outer surface of labial palpus brown intermixed with pale brownish­yellow scales to apical margin of segment II, inner surface pale brownish yellow intermixed with few brown scales; scape of antenna pale brownish yellow intermixed with few brown scales, flagellum with alternating bands of pale brownish­yellow and brown 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 pale brownish yellow.

Thorax: Tegula and mesonotum brown basally, pale brownish yellow distally. Legs brown intermixed with pale brownish­yellow scales to apical margins of all segments and tarsomeres. Forewing (Fig. 357): Length 5.9–6.0 mm (n = 3), pale brownish yellow intermixed with pale yellow and few brown scales; cell with 2 small, brown spots, 1 spot near middle, 1 spot near distal end [specimens with spots present or absent]. Undersurface brown with pale brownish­yellow scales along costa and between CuP and anal margin. Hindwing: Pale gray.

Abdomen (Fig. 210): Male with 5 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 211–212): Uncus elongate, broadly constricted above a wide base, gradually widened apically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing midway between posteroventral margin, gradually widening to base of uncus; costa of valva gradually upturned broadly from basal process to dorsal furca; apex widely bifurcate, furcae slightly convergent apically; dorsal furca falcate, large, about 6 times longer than ventral furca; sacculus twisted apically, constricting valva slightly beyond midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica denticulate, bearing a large crescent­shaped apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Type Examined: Lectotype ɗ, designated by Clarke, “ Trinidad,.2.28.”, “BM Slide No. 6117.” [BMNH].

Other Specimens Examined: (3 ɗ): “ COSTA RICA, Prov[incia] Limón, Sector Cedrales de la Rita, 3 km N del Puente Río Suerte, Ruta Puerto Lindo, 10 m, Oct. 1996, E. Rojas, L­ 278600, 566500, # 44661”, “CRI002, 492676”, “Slide No. 852”; “CRI002, 492671”, “Slide No. 853”; “CRI002, 492794”, (2 in INBio, 1 in USNM).

Distribution ( Map 38 ): Glyphidocera zophocrossa is known from one collecting site in north­central Costa Rica, north of the Cordillera Central, and from specimens collected from Trinidad off the coast of Venezuela ( Meyrick, 1929).
