Diagnosis.— Relationships between
Glyphidocera positurae
and its congeners are difficult to determine because of the unique combination of features possessed by the former that include an abdomen with large sex scales between terga
2–3 in
male, costal furcae of valva equal in size and constricted basally, and vesica of aedeagus with a small conical apical cornutus.
Description.— Head: Vertex and frontoclypeus pale brown; outer surface of labial palpus pale brown intermixed with few palebrown scales, inner surface pale brown; scape of antenna pale brown, flagellum with alternating bands of palebrown 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 pale brown.
Thorax: Tegula and mesonotum pale brown. Legs brown intermixed with palebrown scales to apical margins of all segments and tarsomeres. Forewing (Fig.
356
): Length
5.9 mm
(n =
2
), pale brown intermixed with few brown scales; cell with
3
brown spots,
1
spot near middle,
2
spots near distal end. Undersurface brown. Hindwing: Brownish gray.
Abdomen (Fig.
207
): Male with
3
transverse, irregular rows of sex scales on intersegmental membrane between terga
2–3
.
Male Genitalia (Figs.
208–209
): Uncus elongate, wide at base, broadly constricted at
1
/
3
, broadly widened near middle, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a wide base, fusing dorsally, extending widely to base of uncus; costa of valva slightly emarginate medially, broadly rounded distally to a constricted subapical part; apex bifurcate, each furca widely divergent, about equal in size; sacculus twisted apically slightly before midlength, constricting valva, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many small conical cornuti, and bearing a small, conical, apical cornutus.
Female Genitalia: Unknown.

, north of the Cordillera Central.
Etymology: The species epithet
positurae
is derived from the Latin “positura,” meaning posture.
