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 4th 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.

Distribution (
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.
