Description. Male (Figs 39, 40, 111). Forewing length 2.2–2.7 mm (2.5±0.2,5), wingspan 4.8–5.8 mm. Head: frontal tuft yellowish white to ochreous, collar ditto; scape yellowish white; antenna brown grey, with 43–47 (44.2±1.8,5) segments. Thorax and forewings dark fuscous to black with paler scale bases giving some irroration; a straight dull white, medial fascia, usually wider at dorsum than costa; cilia-line more or less distinct; cilia ochreous grey; underside brown-grey, a narrow line of dark fuscous scales under costal fold near wing base. Hindwing and cilia grey, distinct field of androconial scales on basal half, reaching up to the dorsal margin, dark brown along dorsum, white near hairpencil, hair pencil ochreous; underside grey. Abdomen brownish black, with yellowish anal tufts.
Female. Forewing length 2.2–2.6 mm (6), wingspan 4.9–6.2 mm. Antenna with 30–34 (5) segments. As in male, but hindwing without androconial scales.
Male genitalia (Figs 46, 51). Capsule length 250–265 μm. Vinculum distinctly concave anteriorly. Tegumen broadly rounded to almost truncate, without distinct processes or lobes caudally, with several long setae. Gnathos central element broadly triangular, lateral processes broad and rounded caudally. Valva length 185–210 μm, broad, inner margin with an indistinct basal bump, suddenly narrowed, not evenly curved; outer margin also slightly angled ca ¼ from tip, sublateral processes shorter than ½ transtilla length. Aedeagus 360–400 μm long, with distinct cathrema, with many very small cornuti in vesica, ventral pair of carinae simple, pointed.
Female genitalia (Figs 55, 59, 63). T8 with ca 14–17 setae on either side; T8 with rounded corners, and posteriorly straight. Papillae anales broadly rounded, with about 12–15 short setae each. Apophyses short and thick. Vestibulum with distinct vaginal sclerite and a “spiculate” pouch without spines. Corpus bursae ca. 560–600μm long, almost globular, covered with minute pectinations; signa almost similar, ca 330–370 μm long (n=2), approximately 1.9–2.1 as long as wide, ca 12 cells in width. Ductus spermathecae with about 5.5 sclerotized convolutions.
