Diagnosis.— Glyphidocera cerula  can be distinguished from its congeners by several unique features, including male with a large elliptical­shaped, membranous internal cavity, within an area from the middle of tergum­ 2, extending posteriorly to the middle of tergum­ 4, containing many elongate sex scales in male; a short sacculus; an elongate distal part of valva; and a broad, triangular­shaped costal furca of the valva.

Description.— Head: Vertex and frontoclypeus grayish brown; outer surface of labial palpus brownish gray intermixed with few yellowish­brown scales to apical margins of all segments, inner surface yellowish­brown intermixed with few grayish­brown scales; scape of antenna grayish brown intermixed with few yellowish­brown scales, flagellum with alternating bands of yellowish­brown and brown scales; male 4 th 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 4 th 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. 305): Length 7.2 mm (n = 1), grayish brown intermixed with few brown and yellowish­brown scales; cell with 1 large brown spot near distal end [wing slightly rubbed]. Undersurface brown. Hindwing: Pale brown.

Abdomen (Fig. 54): Male with a large elliptical­shaped, membranous, internal cavity, within an area from the middle of tergum 2, extending posteriorly to the middle of tergum 4, containing many elongate sex scales.

Male Genitalia (Figs. 55–56): Uncus elongate, wide at base, slightly constricted from above, gradually narrowed apically, apex narrowly rounded; gnathos protuberant, moderately widened throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen absent; valva nearly straight from a shallow depression slightly beyond a basal digitate process to a slightly decumbent apical furca; furca wide, apex narrowly rounded; sacculus twisted apically, constricting valva near 1 / 3 length, widening distoventrally forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing and a moderately elongate, conical, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.
