Glyphidocera ambrosiae , new species

(Figs. 231–233, 364, Map 42 )

Diagnosis.— Glyphidocera ambrosiae , G. luxuriae , and G. coturnicis are similar by sharing sex scales between abdominal terga 2–3 in male, a wide gnathos, a dorsal strut of tegumen that is widened basally, a valval cucullus with a broadly rounded apicoventral margin, and costal furcae of the valva that are divergent. However, G. ambrosiae differs from the latter species by having a longer valval cucullus and a vesica of aedeagus with an apical cornutus with a bulbus base.

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

Thorax: Tegula and mesonotum brown intermixed with few dark­brown scales. Legs brown intermixed with pale­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 364): Length 5.8–6.9 mm (n = 19), pale brown intermixed with brown and dark­brown scales, cell and surrounding areas paler than marginal areas; cell with 2 large, dark­brown oblique spots, 1 spot near middle, 1 spot near distal end; one short, dark­brown median streak near base. Undersurface brown intermixed with palebrown scales along costa. Hindwing: Pale brown.

Abdomen (Fig. 231): Male with 4 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 232–233): Uncus elongate, wide at base, broadly constricted near 1/3, broadly rounded apically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing about 2/3 length from a wide base, extending dorsally, gradually widening to base of uncus; costa of valva nearly straight from a shallow depression slightly beyond a straight, basal, digitate process to a gradually upturned dorsal furca; apex widely bifurcate, each furca parallel; dorsal furca large, falcate; ventral furca extending slightly beyond outer margin of cucullus; sacculus twisted apically, constricting valva near midlength, widening distoventrally forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a large, apical cornutus; cornutus apically conical with a slightly bulbous base, one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 42 ): Glyphidocera ambrosiae is known from north­western Costa Rica along the Cordillera de Guanacaste, east to the Cordillera Central, and from the Caribbean Coast south to the Pacific Ocean.

Etymology: The species epithet ambrosiae is derived from the Latin “ambrosia,” which means “food of the gods.”
