Glyphidocera raedae , new species

(Figs. 57–59, 306, Map 10 )

Diagnosis.— Glyphidocera raedae can be distinguished by a unique combination of features possessed that include a large gnathos that is apically setose, a digitate process of valva that is widened basally, a triangular­shaped costal furca of the valva, a cucullus that is dilated from the base of the costal furca to the apicoventral angle, and the presence of a small apical cornutus within the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus grayish brown; outer surface of labial palpus grayish brown intermixed with few yellowish­brown scales to apical margin of segment II, inner surface yellowish brown intermixed with few grayish­brown scales; scape of antenna grayish brown intermixed with yellowish brown scales, proximal 6–7 flagellomeres yellowish brown, distal flagellomeres with alternating bands of brown and yellowish­brown scales; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4th flagellomere; proboscis yellowish brown.

Thorax: Tegula and mesonotum grayish brown. Legs grayish brown intermixed with yellowish­brown scales to near apical margins of all segments and tarsomeres. Forewing (Fig. 306): Length 5.9 mm (n = 1), grayish brown intermixed with yellowish­brown scales; cell and surrounding areas paler than marginal areas; cell with 3 grayish­brown spots, 1 large spot near middle, 2 smaller spots at base and distal end. Undersurface grayish brown. Hindwing: Grayish brown.

Abdomen (Fig. 57): Male with 3 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 58–59): Uncus elongate, narrow throughout length, slightly constricted near midlength, apex narrowly rounded; gnathos setose, 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 the base of uncus; costa of valva distally upturned, with a slightly decumbent and acuminate apical furca; base of costa bearing a digitate process with a widened base; sacculus twisted apically, constricting valva slightly beyond midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose, with outer margin nearly straight from base of costal apex to apicoventral angle; vesica of aedeagus denticulate, bearing a stout, conical, apical cornutus; cornutus slightly shortened on one side, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 10 ): Glyphidocera raedae is known from a single collecting site within the coastal area of the Osa Peninsula.

Etymology: The species epithet raedae is derived from the Latin “raeda,” meaning coach.
