Tang, Zixiang, Wang, Jie, Li, Weihai & Bozdoğan, Hakan, 2024, Identity on Filchneria heteroptera (Wu, 1938) (Plecoptera: Perlodidae) with a new record of Paraleuctra cercia (Okamoto, 1922) from China, Zootaxa 5419 (3), pp. 430-438 : 437

Paraleuctra cercia ( Okamoto, 1922)

Examined material. China: 15 males and 18 females ( HIST), handpicking, Heilongjiang Province, Harbin City, Xianglushan , 342 m, N 45.34 ’27.16’’, E 127.31 ’56.81’’, 2022. V.2, leg. Jie Wang & Weihai Li ; 1 male and 10 females ( CAU), Liaoning Province, Kuandian County, 2007. malaise traps .

Remarks. Leuctra cercia was originally described by Okamoto (1922) from Japan and subsequently transferred to Paraleuctra Hanson, 1941 by Kawai (1976). Later it was reported from Russia ( Zhiltzova 1976) and South Korea ( Kim et al. 1998). Teslenko (2006) recorded this species from Jilin Province, China. Herein, P. cercia is formally reported as a new record species of Heilongjiang and Liaoning provinces, China.

Zwick (2010) noted aberrant females with a cone-shaped projection on the anterior of sternum 8 from The Republic of Korea and Russian Far East, but at that time no adult males had been collected with the Korean females and these females were putatively identified as P. cercia . All the present female specimens have such cone-shaped projection of sternum 8 and males are not readily morphologically distinguishable from P. cercia .
