Description.
Male. Forewing length 3.00-3.04 mm (3), wingspan 6.5-6.9 mm. Head: frontal tuft and collar dark brown to black. Antennae long, with 46-48 segments (2). Thorax dark brown to blackish fuscous. Forewings dark
brown to blackish fuscous, almost uniform, sometimes slightly irrorate, tornal and to a lesser extent, costal spots white; cilia white beyond ill-defined cilia-line. Hindwing (fig. 11) with long white hair-pencil, of more than ⅓ hindwing length, surrounded by white lamellar scales. Humeral lobe and costal emargination more pronounced than in other species.
Female. Forewing length 3.60-3.64 mm (2), wingspan 7.8-8.4 mm. Antennal segments 40-41 (2). Costal and tornal spot more pronounced than in male.
Male genitalia. Capsule length 377-429 µm (4), slightly wider than in atrifrontella: 291-343 µm. Tegumen slightly cuspidate. Gnathos (fig. 282) with central element long and narrow, parallel-sided. Valva (fig. 232) length 296-321 µm (4), approximately triangular, slender, but in comparison with atrifrontella wider, without any inner lobe, tip slightly hooked; transtillae with ventral arms intermediate in length between atrifrontella and longicaudella. Aedeagus 454-463 µm (4), constricted at level of opening for ductus ejaculatorius; ventral carinae long, approximately one third of total length aedeagus, with hardly serrate or smooth outer margins: lateral and dorsal carinae connected by prominent rim, stout and pointed, the dorsal longer. Vesica with distallv a sclerotised plate with indistinct folds or ridges, in addition to small cornuti.
Female genitalia. T8 with many long hairs, a row of 16-20 thicker and very long setae along anterior margin of T8, scales absent; anterior margin slightly indented. Anal papillae with 6-10 setae. Posterior apophyses reaching slightly beyond anterior apophyses. Vestibulum with pair of indistinct sclerotisations. Corpus bursae ± 1100 µm, covered with pectinations, partly in concentric bands around signa; signa elongate, almost similar, length 390-495 µm (6). 3.6-4.0 X as long as wide. Ductus spermathecae with 2½-3 convolutions becoming wider distally.
Larva. Yellow, very elongate. Head-capsule brown. Ventral plates absent. See also Schönherr (1958).
