Glyphidocera reginae , new species

(Figs. 156–158, 339, Map 49 )

Diagnosis.— Relationships between Glyphidocera reginae and its congeners are difficult to determine because the former possesses a unique combination of features that include an atrophied dorsal strut, a long digitate process of the valva (with an abruptly curved apex); costal furcae of valval costa small and subequal in size; vesica of aedeagus with an elongate and narrow apical cornutus.

Description.— Head: Scales on vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus with segments I–II brown intermixed with few palebrown scales to apical margin, segment III brown intermixed with few pale­brown scales; inner surface pale brown intermixed with few brown scales; scape of antenna brown intermixed with few pale­brown scales, flagellum with alternating bands of brown and palebrown scales; male 4th flagellomere not protuberant, 5th and 6th flagellomeres slightly excavated; [proboscis missing].

Thorax: Tegula and mesonotum pale brown. Foreleg brown intermixed with palebrown scales to apical margins of all segments and tarsomeres [pterothoracic legs missing]. Forewing (Fig. 339): Length 7.7 mm (n = 1), pale brown intermixed with few brown scales; cell with 2 small spots, 1 spot near middle, 1 spot near distal end; a few marginal spots present. Undersurface brown intermixed with pale­brown scales along costa. Hindwing: Pale brown.

Abdomen (Fig. 156): Male with 2 transverse rows of sex scales on intersegmental membrane between terga 2–3 and between terga 3–4. Sex scales between terga 2–3 about twice as large as sex scales between terga 3–4.

Male Genitalia (Figs. 157–158): Uncus elongate, wide at base, broadly constricted near midlength, narrowly rounded apically, apex narrowly rounded and setose; gnathos protuberant, wide throughout length, apically upturned; tegumen nearly parallelsided throughout length; dorsal strut of tegumen with arms convergent, fusing medially, atrophied dorsally; costa of valva broadly emarginate from shallow depression beyond a basal digitate process dorsal furca; apex narrowly bifurcate; dorsal furca about 3 times larger than ventral furca, margin beneath ventral furca shallowly serrate; costa of valva bearing an elongate, apically curved, digitate process; sacculus twisted apically near midlength, constricting valva, widening distoventrally, forming elongate a narrowly rounded cucullus; cucullus membranous and setose; vesica of aedeagus sparsely denticulate, bearing an elongate, conical, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.
