Type locality.

“ Yunnan Province, Diqing Prefecture, Weixi County, Pantiange Township, A valley near Zhazi; 2970 m ”.

New material examined.

China • 1 male, 1 female & 8 nymphs ( ZAFU); Yunnan Province, Dali Bai Autonomous Prefecture, Jianchuan County, Xiangtu Township ; 15 Apr. 2025; He Zhang leg; ZAFU -IC-200021 to 200030 • 1 male & 1 female ( SWU); Yunnan Province, Dali Bai Autonomous Prefecture, Jianchuan County, Xiangtu Township ; 15 Apr. 2025; He Zhang leg; SWU -B-CC-010087 to 010088 .

Remarks.

The male specimen collected in Jianchuan County exhibits dense tegmina markings similar to those of P. pilosa and P. longiseta . However, both sexes of this population possess a distinct longitudinal yellow line medially on their abdominal sternites, a characteristic allowing their immediate distinction from P. longiseta . The tegmina markings pattern of the Jianchuan male, however, is noticeably denser than that of the P. pilosa holotype (closer to specimens from Blue Moon Valley, Yulong Snow Mountain) and exhibits a significantly greater body length (excluding wings: 20.3 mm vs. 15.6–16.8 mm in the type locality). Given the minimal genetic divergence from other P. pilosa populations (5.13–6.90 %) and proximity to its known distribution, we tentatively assign these Jianchuan specimens to P. pilosa in the present study.
