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.
