A new species of the Neoperla clymene group (Plecoptera, Perlidae), N. chebalinga sp. n. from Guangdong Province of southern China is described, illustrated, and compared with related taxa. The new species is characterized by the slender aedeagal tube, strongly sclerotized dorsally, and weakly sclerotized ventrally with an upcurved, medial, finger-like membranous lobe. Additionally the aedeagal sac gradually tapers to a blunt apex with a dorsoapical patch of spines. A supplementary description of the female of N. mnong Stark, 1987 from Guangdong Province, China is also given.

Specimens used in this study were collected from riparian areas by hand and preserved in 75% ethanol. Abdomens were cleared in 10% NaOH. Details of the morphology were studied with a Leica MZAPO microscope, and color illustrations were taken by Leica SZ45 and S4800 FESEM, both in Yangzhou, Jiangsu Province, China. All studied material, including the holotype and paratypes of the new species, are deposited in the Insect Collection of Yangzhou University, China.
Holotype male: China: Guangdong Province, Chebaling Nature Reserve, 114.1320E, 24.7128N, 17 June, 2009, leg. Hai-Yang Xue and Bo Yu. Paratypes: 4 males and 2 females, same data as holotype.
Distinguishing characteristics of this species include a slender aedeagal tube that has an upcurved, medial, finger-like, membranous lobe on the ventral surface, and a short, blunt, ventrally curved aedeagal sac with a dorsoapical patch of spines.
Adult habitus. General body color yellow patterned with brown. Head slightly wider than pronotum with a brown stigma on anterior frons and a subtriangular dark brown area covering ocelli; compound eyes dark and antennae brown (Figs

The species is named after the type locality, Chebaling Nature Reserve.
The new species is a member of the N. clymene group possessing a slender and mostly sclerotized aedeagal tube. The processes of terga 7–8 and aedeagus of the new species are similar to those of N. furcostyla Li & Qin, 2013 (in:
