Pseudoeupolyphaga pilosa: Han et al. 2024: 166. Type locality. “ Yunnan Province, Diqing Prefecture, Weixi County, Pantiange Township, A valley Near Zhazi; 2970 m ” New material examined. China • 1 male, 2 females; Yunnan Province, Lijiang City, Yulong Snow Mountain, Blue Moon Valley; 24 Jul. 2022; Wei Han, Lin Guo leg • 1 male, 1 female; Yunnan Province, Lijiang City, Wenbi Mountain; 24 Jul. 2022; Wei Han, Lin Guo leg • 1 male, 4 nymphs; Yunnan Province, Weixi County, Badi Village, Luodatang countryside; 25 Jul. 2022; Wei Han, Xin-Xing Luo, Lin Guo leg. Remarks. This species was previously only documented in Pantiange Township, Weixi County, Yunnan Province. However, a recent collection in Yunnan has expanded its distribution range. In samples collected at various sites, the density of markings on the male tegmina varied (Fig. 13 A – F). Markedly sparser markings were observed on the samples from Pantiange Township (Qiu et al. 2018: fig. 8 A, B) and Luodatang countryside in Weixi County (Fig. 13 A, B) compared to those from Yulong Snow Mountain (Fig. 13 C, D) and Wenbi Mountain (Fig. 13 E, F). Additionally, the male abdomens of samples from Pantiange Township, Yulong Snow Mountain, and Wenbi Mountain were dark brown to black, while those from Luodatang countryside were yellowish-brown. Genetic distance analyses revealed that the genetic distance between samples from the four different collection sites ranged from 3.92 % to 7.54 %. Given the proximity of these new distributions to the type locality, and the absence of significant differences in oothecae (Fig. 15 F, G, O, P; Qiu et al. 2018: fig. 38 I, Q), the samples from the new location were temporarily classified as distinct geographic populations of P. pilosa.
