Nemotois augites: Meyrick 1938: 29 (partim); Popescu-Gorj 1992: 137 (partim); Sun et al. 2022: 306‒307, Figs. 4, 29 (misidentification).
Diagnosis. Differs from N. augites (Fig. 1) by light yellowish-white frons and shorter vinculum with deep medial indentation on the distal margin. From N. amatella (Figs. 3‒6) it differs by the absence of bright yellow spot(s) or wide stripes in the apical part of forewing, longer anellus and presence of carinae in apical part of phallus. From both these species it also differs by the absence of a finger-like process(es) at the apex of phallus in male genitalia.
Etymology. Named after the type locality, Yunnan province of China. This name is a noun in apposition.
Description. Male (Fig. 2). FWL 10.2 mm, WLR 0.31. Vertex covered with both yellow and dark brown piliform scales; frons pale, light yellowish-white. PLB 1.8 × vertical eye diameter, light brown; dorsally with appressed yellowish white scales, ventrolaterally with dense cover of raised piliform scales, which are white or yellowish white on internal side of the palpus but brown on ventral and external sides of it. Proboscis brown, base with yellowish-white scales. Eyes not enlarged; interocular index 0.7. Antennae broken in the holotype; in paratypes 2.8‒2.9 × FWL (Sun et al. 2022); pegs present. Tegulae and thorax bronze. Forewing (Fig. 8) monotonously pale yellow with ochreous tint, suffused with brown bronze shimmer scales; these scales are more abundant in the apical part of forewing than in the basal part of it. The wing pattern diffuse, with only a few thin brown lines along veins in the basal part and thin, almost indistinct, yellowish lines along veins in the apical part. Fascia wide, 0.30 × FWL at costa and 0.22 × FWL at dorsum; external margins slightly concave; reaches costal margin at 0.5 × FWL. Medial band of fascia light yellow; lateral bands silver grey, of about the same width as medial band; margins of all bands with thin rows of dark brown scales. Fringe brown with bronze lustre. Hindwing brown with slight bronze lustre; costal area from grey proximally to yellowish distally; anal zone and dorsal wing margin with elongate bronze scales, which form dark marginal line; R+M1 stalked; fringe light brown. Legs brown dorsolaterally, yellowish ventrally; bases of all segments lighter than their apices; basal 0.8 of hind tibia light yellow; hind tibia with sparse rows of light brown piliform scales on both ventral and dorsal sides. Epiphysis at 0.5, not reaching apex of tibia.
Female unknown.
Male genitalia (Fig. 14). Tegumen dome-shaped, with prominent medial ridge. Socii 0.7 × diameter of phallus. Vinculum 2.3 × length of valva, with slightly concave lateral margins; distal margin nearly straight, with deep medial indentation. Tip of tegumen extends beyond tips of valvae. Dorsal valvar margin almost straight; ventral margin wave-shaped; tip narrowly rounded. Valvae fused basally up to 0.25 × total length; internal valvar margins distinct. Anellus 0.5 × length of valva. Transtilla with moderately long medial process. Juxta 0.45 × length of phallus; arrow head wide (WLR 0.65), with widely rounded tip and short rounded lateral arms. Phallus 1.05 × length of vinculum, almost straight, with two shallowly wave-shaped carinae articulated to its ventral side at 0.7 × length of phallus (counting from its base); apical part of phallus consists of pointed ventral lobe and wide dorsal lobe; base of phallus narrow, with parallel margins (see from ventral side).
Comments. The photograph of the holotype and information on its labels is available at http://clasate.cimec.ro/ detaliu.asp?k= C11DD04AFBB84E07B0D90DD9067B8805. The holotype of N. yunnanica has been erroneously designated as the lectotype of N. augites by Popescu-Gorj (1992). For details, see comments on N. augites above.
