Zhao, Meng-Yuan, Huo, Qing-Bo & Du, Yu-Zhou, 2019, A new species of Styloperla (Plecoptera: Styloperlidae) from China, with supplementary illustrations for Styloperla jiangxiensis, Zootaxa 4608 (3), pp. 555-571 : 566-570

Styloperla jiangxiensis Yang & Yang, 1990

Material examined: 1³, China, Guangdong Province, Yao Autonomous County of Ruyuan, “Nanling protection station” (location unidentified: presumably at the present Nanling National Forest Park), 1000m, 2004-VII-8, leg. Lu Yan-Yang.

Adult habitus: Similar to the new species, except antennae, palpi, legs, wing veins, and cerci appear brighter. Median occiput without posterior pigment only with aecdysial line (Fig. 21).

Male: Forewing length 15.0 mm, hindwing length 14.1 mm, body length 13.8 mm. Tergum 10 with a median slim sclerite. Hair on sternum 9 slightly thicker; hair bush fusiform (Figs. 22–24). Basal cercal segment with a double process, the longer one curved along the inner cercal margin to a trifurcated terminating, and the shorter one with similarly 2–3 small teeth on apex. Cercal segments 2–4 bear small clusters of mid-dorsal multispines (Figs. 25–26).

Female: Unknown.

Egg: Unknown.

Nymph: Unknown.

Discussion: The single specimen listed above closely agree with the description of S. jiangxiensis by Yang & Yang (1990). Specimens identified by Stark and Sivec (2007) tentatively as “ S. jiangxiensis ” are S. starki . The material listed by Stark and Sivec (2007) was collected from Mount Longwangshan in Zhejiang Province. Mount Jinggangshan, the type locality of S. jiangxiensis is in southwestern Jiangxi Province of southeastern China, adjacent to Fujian, Guangdong, Hunan, and Zhejiang provinces. This location is geographically connected with the Nanling Mountains ( Fig. 27 ).
