Glyphidocera diciae , new species

(Figs. 129–131, 330, Map 24 )

Diagnosis.— Relationships between Glyphidocera diciae and its congeners are difficult to determine because of the unique combinations of features possessed by the former that include, with 4 irregular transverse rows of sex scales on intersegmental membrane between terga 2–3 in male, one transverse row of sex scales between terga 3–4 in male [sex scales between terga 2–3 about twice diameter of sex scales between terga 3–4], dorsal strut of tegumen with arms convergent from a widened base fusing dorsally near 1/3 distance between posteroventral margin and base of uncus, and a small toothlike process between the furcal bifurcation of the costal valva.

Description.— Head: Marginal scales of vertex and frontoclypeus dark brown, median scales dark brown tipped with grayish yellow; outer surface of labial palpus dark brown with few grayish­yellow scales to near apical margin of segment II, inner surface dark brown intermixed with grayish­yellow scales mostly along apical margin of segment II, and basal margin of segment III; scape of antenna dark brown, with grayish­yellow scales along apical margin; basal 4 flagellomeres dark brown, remaining flagellomeres brown; 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 dark brown.

Thorax: Tegula and mesonotum dark brown intermixed with dark­brown scales tipped with brown. Foreleg and midleg dark brown intermixed with grayish­yellow scales along apical margins of all segments and tarsomeres; hindleg as above except, tarsomeres grayish yellow. Forewing (Fig. 330): Length 8.1 mm (n = 1), dark brown intermixed with grayish­yellow scales; cell with 2 dark­brown spots, 1 near middle, 1 near distal end. Undersurface brown intermixed with grayish­yellow scales along costa. Hindwing: Brown intermixed with sparse rows of narrow, spatulate, pale grayish­brown scales.

Abdomen (Fig. 129): Male with 4 irregular, transverse rows of sex scales on intersegmental membrane between terga 2–3 and with 1 irregular, transverse row of sex scales between terga 3–4. Sex scales between terga 2–3 about twice diameter of sex scales between terga 3–4.

Male Genitalia (Figs. 130–131): Uncus elongate, wide at base, broadly constricted near midlength, broadly rounded apically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, apex emarginate medially; tegumen slightly widened basally; dorsal strut with arms convergent from a wide base, fusing at 1/3 length, dorsally extending widely to base of uncus; costa of valva slightly emarginate medially from a shallow depression beyond a basal, digitate process to a slightly upturned dorsal furca; apex widely bifurcate, with a small medial toothlike process between furcae; furcae divergent, equal in size; base of costa bearing a digitate process, abruptly downturned apically; sacculus twisted apically, constricting valva slightly near midlength, widening distoventrally, forming an elongate cucullus; cucullus membranous and setose, with a narrow outer margin; vesica of aedeagus with 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 diciae is known from a single collecting site in north­western Costa Rica along the Cordillera de Guanacaste.

Etymology: The species epithet diciae is derived from the Latin “dicia,” meaning power.
