Material examined. Holotype: ♂, Holotype of Aulocera longanfua Lang , China: Sichuan, Pingwu, Huangtu-liang Pass , 3300 m, 30.VII.2018, leg. S. Y. Lang ( CQMNH) ; paratypes: 3 ♂♂ 1 ♀, Paratypes of Aulocera longanfua Lang , same collecting data, leg. S. Y. Lang & J. Hou ( LSY) .

Diagnosis. Aulocera longanfua can be separated from the related A. sybillina by the combination of the following characters: 1) in the male, on the forewing underside, the white postdiscal spots are much smaller; 2) on the forewing upperside, the male brand is narrower and situated further separated from the white postdiscal spots in the spaces 1b, 2 and 3, whereas it is broader and nearly attached to the white spots in A. sybillina ; 3) in the female, on the hindwing upperside, the white discal band is much narrower; 4) the lamina of the androconium ( Fig. 31d View FIGURE 31 ) is obviously slenderer than those of A. sybillina ( Figs. 31a–c View FIGURE 31 ); 5) in the male genitalia, the valva ( Fig. 30d View FIGURE 30 ) is shorter and narrower than that of A. sybillina ( Figs. 30e–h View FIGURE 30 ).

Aulocera longanfua is also very similar to the nominate subspecies of A. pygmaea but can be distinguished from it by the combination of the following characters: 1) in the female, the white discal spots on both sides are smaller; 2) on the hindwing upperside, the white discal band is discrete in the spaces 1, 2 and 3, whereas it is more continuous in A. pygmaea ; 3) on the hindwing, the white discal band in the spaces 1b to 3 is curved on both sides, whereas it is nearly straight in A. pygmaea ; 4) the base of the lamina of the androconium ( Fig. 31d View FIGURE 31 ) is wider and the distal stalk is somewhat longer, whereas it is gradually narrowing towards the basal stalk in A. pygmaea ( Fig. 31f View FIGURE 31 ); 5) in the male genitalia, the subdistal section of the valva ( Fig. 30d View FIGURE 30 ) is somewhat narrower than that of A. pygmaea ( Fig. 30a View FIGURE 30 ). From the sympatric A. pygmaea vadimi , it can be distinguished by further characters in addition to those mentioned above: 1) in the male, on the forewing upperside, the brand is present, whereas it is absent or vestigial in A. pygmaea vadimi ; 2) on the forewing upperside, the discal spots are usually larger; 3) in the female, on the forewing upperside, the discal spots are smaller.

Remarks. Sakai et al. (2001) mentioned a record of Aulocera sybillina with the data as “Pingwu (Pingwu-Jiuzhaigou) (3,300 m), Sungqu (Songpan County), 16.VIII.1987 ” without any further comment. Although the information seems vague, the site “Pingwu-Jiuzhaigou, 3,300 m ” is clearly the same as Huangtu-liang Pass which is of the same altitude and is the type locality of A. longanfua and A. pygmaea vadimi . However, the collecting date is half a month later than that of A. longanfua and A. pygmaea vadimi . Since Sakai et al. (2001) did not illustrate any specimen with the above information, it is not known whether this record is the true sybillina or just a longanfua .

Distribution. China (N. Sichuan).
