(93) Nemophora yunnanica Kozlov, 2023

Nemophora yunnanica Kozlov, 2023b: 97 , figs. 2, 8, 14 (TL: China, Yunnan, Lijiang; MINGA, NKU).

Nemotois augites: Meyrick 1938: 29 (partim); Popescu-Gorj 1992: 137 (partim); Sun et al. 2022: 306, figs. 4, 29 (misidentification).

Diagnosis. This species differs from N. augites by light yellowish-white frons and shorter vinculum with deep medial indentation on the distal margin. In addition, this species differs from N. amatella by the absence of bright yellow spots or wide stripes in the apical forewing, longer anellus and presence of carinae in apical part of phallus ( Kozlov 2023b).

Specimens examined. Not available in this study.

Distribution. China (Yunnan).

Remarks. Kozlov (2023b) described this species based on the lectotype of ‘ Nemotois augites ’ in MINGA and named it as ‘ Nemophora yunnanica ’. In addition, Kozlov (2023b) considered that four male specimens figured by Sun et al. (2022) under the name ‘ Nemophora augites (Caradja et Meyrick, 1938) ’ are misidentification, and attributed them to the paratypes of Nemophora yunnanica .

Adults usually fly above the ground at 9–10 a.m. and 3– 4 p. m. ( Kozlov 1997c). Kozlov (1997c) also noted that this species feeds on the flowers of Lithocarpus formosana , L. kawakamii and Castanopsis longicaudata (Fagaceae) .

3.15 Incertae sedis species

The genus Nemophora consists of many confirmed species groups including the species groups described above and other known or possible species groups, such as the N. kalshoreni group ( Kozlov 2016a), N. laurella group ( Kozlov 2016b), N. fasciella group ( Kozlov 1997a) and a possible N. decoratella group ( Kozlov 2020). In this study, we established some species groups that shared significant common autapomorphic characters. In addition, there are still many species whose species group status has not yet been defined. Here, we record six temporary incertae sedis species, of which N. bispina sp. nov. is described as a new species.
