Glyphidocera burpurae, new species

(Figs. 123–125, 328, Map 23)

Diagnosis.— Relationships between Glyphidocera burpurae and its congeners are difficult to determine because of the unique combinations of features possessed by the former that include, with 4 short, transverse, irregular rows of sex scales on medial surface of intersegmental area between terga 2–3 in male, a wide gnathos, a valva with a basally widened and falcate costal furca, and an elongate and narrow apical cornutus of the aedeagal vesica.

Description.— Head: Scales of vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus brown intermixed with few pale­brown scales, segment II with pale­brown scales along apical margin; inner surface pale brown intermixed with few brown scales; scape of antenna brown intermixed with few pale­brown scales, flagellum with alternating bands of pale­brown and brown scales; male 4th flagellomere distally dilated, protuberant and curved, forming a deep concavity opposite deeply excavated flagellomeres 5–6; proboscis pale brown.

Thorax: Tegula and mesonotum brown. Legs brown intermixed with pale­brown scales along apical margins of all segments and tarsomeres. Forewing (Fig. 328): Length 5.0– 5.2 mm (n = 3), brown intermixed with pale­brown scales; cell with 2 faint brown spots, 1 spot near middle, 1 spot near distal end. Undersurface brown. Hindwing: Darker brown than forewing.

Abdomen (Fig. 123): Male with 4 short, transverse, irregular rows of sex scales on medial surface of intersegmental area between terga 2–3.

Male Genitalia (Figs. 124–125): Uncus elongate, wide at base, gradually narrowed near 1/4, parallsided apically, apex narrowly rounded and setose; gnathos protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially and narrowly from posteroventral margin to base of uncus; costa of valva slightly upturned from a shallow depression beyond a basal digitate process to apical furca; furca falcate, with a wide base, and a small toothlike process beneath on posteroventral margin; sacculus twisted apically near midlength, constricting valva, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus sparsely denticulate, bearing a conical, apical cornutus; cornutus with a shortened side near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Paratypes (2 ɗ): 1 ɗ, Same label data as holotype except, “CRI000, 587986”, “Slide No. 788”; 1 ɗ, “May”, “CRI000, 646539”, “Slide No. 796”, (1 in INBio, 1 in USNM).

Distribution (Map 23): Glyphidocera burpurae is known from one coastal collecting site in southeastern Costa Rica, south of the Osa Peninsula.

Etymology: The species epithet burpurae is derived from the Latin “burpura,” meaning royalty.
