Glyphidocera comae , new species

(Figs. 132–134, 331, Map 24 )

Diagnosis.— Glyphidocera comae is most similar to G. animae but differs from the latter species by having a basally narrower tegumen, a basally narrower dorsal strut of the tegumen, and a more protuberant furcal bifurcation of the valval costa.

Description.— Head: Scales on vertex and frontoclypeus grayish orange tipped with pale grayish orange; outer surface of labial palpus dark brown intermixed with grayishorange scales to near apical margin of segment II, inner surface pale grayish orange intermixed with few brown scales; scape of antenna dark brown, or brown intermixed with few grayish­orange scales, flagellum with alternating bands of pale grayish­orange and brown scales; male 4th flagellomere distally dilated, protuberant and curved, forming a shallow concavity opposite deeply excavated flagellomeres 5–6; concavity nearly closed by setiform scales on apex of protuberance of 4th flagellomere; proboscis pale grayish orange.

Thorax: Tegula and mesonotum with scales grayish orange tipped with pale grayish orange. Legs grayish orange intermixed with pale grayish­orange scales to near apical margins of all segments and tarsomeres. Forewing (Fig. 331): Length 6.0– 6.8 mm (n = 8), grayish orange intermixed with pale grayish­orange and brown scales; cell and surrounding areas paler than marginal areas; cell with 2 large brown spots, 1 spot near middle, 1 spot near distal end; basal streak, on CuP posterior to midcell spot; marginal spots present or absent. Undersurface brown intermixed with few pale grayish­orange scales along costa. Hindwing: Pale grayish orange.

Abdomen (Fig. 132): Male with 3 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3, and 4 transverse, irrgeular rows of sex scales on intersegmental membrane between terga 3–4. Sex scales between terga 2–3 are about 3 times larger than the sex scales between terga 3–4.

Male Genitalia (Figs. 133–134): Uncus elongate, wide at base, broadly constricted at 1/3, apically widened to nearly width of base, apex widely acuminate and setose; gnathos setose, protuberant, narrow throughout length, apex rounded; tegumen nearly parallelsided throughout length; dorsal strut of tegumen with arms convergent, fusing from a widened base, extending narrowly to base of uncus; costa of valva nearly straight from a shallow depression beyond a basal digitate process to an upturned and slightly constricted dorsal furca; apex bifurcate, furcae widely divergent, forming a V­shaped inner margin; sacculus twisted apically, constricting valva near midlength, widening distoventrally forming an elongate and narrowly rounded cucullus, cucullus membranous and setose; vesica of aedeagus with several small, stout, conical cornuti, and bearing an elongate, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 24 ): Glyphidocera comae is known from three collecting sites in Costa Rica; one north­central site north of the Cordillera Central, and two nearby sites in the south­central part of the country along the coast.

Etymology: The species epithet comae is derived from the Latin word for hair ­ coma.
