description: Neoperla pani Chen & Du, sp. nov.   
Figs. 1–9  
 Adult habitus. General color yellow patterned with brown. Head slightly wider than pronotum, with a dark stigma on anterior frons and a distinct median brown area covering ocelli; compound eyes dark and antennae dark brown (Fig. 1). Pronotum disc pale brown with obscure rugosities and dark brown anterior and lateral margins (Fig. 1). Wing membrane subhyaline, veins brown; coxae pale, distal half of femora and basal part of tibia dark brown, tarsi dark brown. Cerci pale (Figs. 8, 9).   
 Male (Figs. 1–6, 8). Forewing length 13.0– 13.5 mm, hindwing length 10.0– 10.5 mm. The posterior margin of tergum 7 with upraised process, covered with dense sensilla basiconica. Tergum 8 with an upcurved tongue-shaped process bearing small spines at distal margin (Figs. 2–3). Tergum 9 without sensilla basiconica. Hemitergal processes of tergum 10 slightly curved medially (Fig. 2). Aedeagal tube strongly sclerotized, ventroapically with a pair of curved finger-like lobes, each lobe gradually enlarging to apex. Aedeagal sac short and gradually tapering to apex; curved ventrally and bearing fine spinules apically (Figs. 4 –6).   
 Female (Figs. 7, 9). Forewing length 14.0– 14.5 mm, hindwing length 11.0– 11.5 mm. Subgenital plate with a median sclerotized area, forming a semicircular notch at the tip (Fig. 7).   
 Type material. Holotype: male, China: Zhejiang Province, Taizhou City, Xianju County, Dan Zhu Primeval Forest, 28.6403 N, 120.5431 E, 2015. X.18, Zhi-Xiang Pan. Paratypes: 2 males and 1 female, same data as holotype.   
 Etymology. The species is named for Zhi-Xiang Pan, who collected the types.   
 Diagnosis. The aedeagal tube of this species has two separate curved finger-like lobes, each lobe gradually enlarging to apex. Additionally, the aedeagal sac is gradually tapering to apex and has fine spinules apically.   
 Remarks. The new species is a member of the N. clymene group. The aedeagal tube and sac of the new species is similar to that of N. duratubulata Du, 1999, N. biprojecta Du, 2001, N. qingyuanensis Yang & Yang, 1995, N. brevistyla Li & Murányi, 2013 and N. yentu Cao & Bae, 2007 (Du 1999, Du 2001, Li et al. 2013a, Yang & Yang 1995, Qin et al. 2013, Cao et al. 2007, Stark & Sivec 2008). However, in N. duratubulata, the aedeagal tube is thinner and the lobes do not enlarge gradually (see Fig. 25– 13 in Du 1999). In N. biprojecta, the lobes are much shorter and not curved (see Figs. 3–4 in Li et al. 2013a). In N. qingyuanensis, the aedeagal tube is much longer and the lobes do not enlarge apically (see Fig. 7 in Li et al. 2013a). In N. brevistyla, the aedeagal tube and sac is much longer, and the lobes are very small (see Figs. 1–2 in Qin et al. 2013). In N. yentu, the aedeagal tube is longer and the lobes are smaller. (see Figs. 75–77 in Stark & Sivec 2008). In addition, the new species can be easily distinguished by the distinct head pattern.
