(Figs. 3–5, 288, Map 1 View MAP 1 )

Diagnosis.— The relationship of G. asymmetricae   to its congeners is difficult to determine because of the extreme asymmetry of the male valvae.

Description.— Head: Vertex and frontoclypeus brown; outer surface of labial palpus brown intermixed with pale­brown scales to apical margin of segment II, inner surface pale brown; scape of antenna brown, flagellum with alternating bands of brown and palebrown scales; male 4 th flagellomere dorsally protuberant and curved, forming a wide and deep concavity opposite slightly excavated flagellomeres 5–6; proboscis brown.

Thorax: Tegula and mesonotum brown. Foreleg brown intermixed with pale­brown scales along apical margins of all segments and tarsomeres, pterothoracic legs pale brown. Forewing (Fig. 288): Length 7.5 –8.0 mm (n = 2), brown intermixed with pale­brown scales; cell with 2 large, faint brown spots, 1 near middle, 1 near distal end. Undersurface brown. Hindwing: Brown.

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

Male Genitalia (Figs. 4–5): Uncus elongate, wide at base, broadly constricted near midlength, broadened medially, apex acuminate and setose; gnathos protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms fusing medially from posteroventral margin to base of uncus; valvae asymmetrical, right valva with apex of costa elongate, forming an upturned furca, about 1 / 4 length of valva; left valva with irregularly truncate, with a downturned apical process arising dorsally and a small toothlike process ventrally; apicoventral area beyond sacculus wider on left valva than on right valva; sacculus twisted apically, constricting valva beyond midlength; digitate process on base of valva absent; vesica of aedeagus denticulate, with a moderately large, conical, apical cornutus; cornutus with one side shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Paratype (1 ɗ): “Est. Queb. Bonita, 50 m Res. Biol. Carara, Prov. Punt., COSTA RICA, R. Zuniga, Jun 1991, L­N­194500, 469850”, “ CRI 000, 349044 ”, “Slide No. 647.”

Distribution ( Map 1 View MAP 1 ): Glyphidocera asymmetricae   is known from one coastal collecting site in southern Costa Rica along Río Tárcoles near the mouth of Golfo de Nicoya.

Etymology: The species epithet asymmetricae   is derived from the Greek “asymmetros,” meaning without symmetry, and refers to the asymmetry of the male genitalia.
