Glyphidocera ancillae , new species

(Figs. 249–251, 370, Map 45 )

Diagnosis.— Glyphidocera ancillae is most similar to G. ranae but differs from the latter by having a smaller gnathos, a smaller digitate process of the valva, a more recurved dorsal furca of the valval costa, and a more elongate and narrow apical cornutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus brown; outer surface of labial palpus with segments I­II brown intermixed with pale­brown scales to apical margin, segment III brown; inner surface of labial palpus pale brown; 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 pale brown.

Thorax: Tegula and mesonotum brown. Legs pale brown. Forewing (Fig. 370): Length 6.2 mm (n = 1), brown, with no distinguishable markings. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 249): Male with 3 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 250–251): Uncus elongate, wide at base, broadly constricted near midlength, widened subapically, gradually tapered to a narrowly rounded apex; gnathos sparsely setose, protuberant, narrowed apically from a wide base, slightly upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially between posteriorventral margin and base of uncus; costa of valva nearly straight from a shallow depression beyond a slightly curved, basal, digitate process to an abruptly recurved dorsal furca; apex widely bifurcate, furcae divergent, dorsal furca at least twice as large as ventral furca; base of costa with a slightly curved, digitate process; sacculus twisted apically, constricting valva near midlength, forming an elongate, broadly curved, and protracted cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing an elongate and narrow cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 45 ): Glyphidocera ancillae is known from one collecting site in north­western Costa Rica near the Cordillera de Guanacaste.

Etymology: The species epithet ancillae is derived from the Latin “ancilla,” meaning maid­servant.
