Glyphidocera pali , new species

(Figs. 195–197, 352, Map 35 ) Diagnosis.— Glyphidocera pali is most similar to G. barbae but differs by having the dorsal strut of the tegumen with a narrower base (lateral arms fused medially and extending from posteroventral margin to base of uncus) and a more narrowly separate costal furcae of valva.

Description.— Head: Vertex and frontoclypeus grayish brown; outer and inner surfaces of labial palpus pale yellowish brown intermixed with few brown and dark­brown scales; scape of antenna pale yellowish brown intermixed with few brown scales, flagellum with alternating bands of pale grayish­brown and brown scales; male 4th flagellomere dorsally protuberant and curved, forming a shallow concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4th flagellomere; proboscis pale yellowish brown.

Thorax: Tegula and mesonotum pale grayish brown. Legs pale yellowish brown intermixed with few brown scales, apical margins of all tarsomeres pale yellowish brown. Forewing (Fig. 352): Length 7.1 mm (n = 1), pale yellowish brown intermixed with few brown scales, with a faint brown spot near distal end of cell. Undersurface pale brown. Hindwing: Pale brown, scales within anal area slightly darker.

Abdomen (Fig. 195): Male with two elliptical­shaped, pairs of sex scale clusters on intersegmental membrane between terga 2–3 and terga 3–4; each cluster with 2 transverse rows of sex scales. Sex scales between terga 2–3 are slightly larger than the sex scales between terga 3–4.

Male Genitalia (Figs. 196–197): Uncus elongate, wide at base, broadly slightly constricted near midlength, broadly rounded distally, 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 from a widened base, extending narrowly to base of uncus; costa of valva nearly straight from a shallow depression beyond a basal, digitate process to an upturned dorsal furca; apex bifurcate, inner margin V­shaped; furcae divergent, dorsal furca narrowly rounded apically, ventral furca pointed; base of costa bearing a long, slanted, digitate process; sacculus twisted apically, constricting valva near midlength, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many stout, conical cornuti, and bearing an elongate, apical cornutus; cornutus with a shortened side near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 35 ): Glyphidocera pali is known from one collecting site in eastcentral Heredia in northern Costa Rica.

Etymology: The species epithet pali is derived from the Latin “palus,” meaning quagmire.
