6364974A6B18FF91FF6EFAF849C4654D.taxon	discussion	Remarks. Neoperla hubleyi Stark & Sivec, 2008 is reported from Guangdong Province, China, for the first time. This identification is based on the male aedeagus, which features a Y-shaped ventral lobe on the aedeagal tube and an aedeagal sac that is mostly covered with scales. The Y-lobe bifurcates in the subapical region, with each arm bearing apical spines. The stalk measures 2.0 X the length of each arm. The tip of the aedeagal sac is armed with fine spines (see fig. 5 in Mo et al. 2020 b). This species is widely distributed throughout the Oriental region. This new provincial record from Guangdong expands its known distribution and further confirms its presence across this biogeographical area.	en	Mo, Raorao, Lin, Aili, Li, Weihai (2025): Comprehensive review of the genus Neoperla (Plecoptera: Perlidae) from Guangdong, China: unveiling two new species and a new record.

6364974A6B19FF91FF6EFD654AF063BC.taxon	discussion	Remarks. The new species belongs to the Neoperla diehli subgroup (Mo et al. 2024; Zwick 1983). It is most similar to Neoperla moae Zeng, Huo & Du, 2024 in having similar terminalia and the hook-like aedeagus (Zeng et al. 2024 b). Both species, however, can be distinguished by details of the aedeagal armature. For the new species (Figs. 2 d, 3 a, 3 c), the arms of the Y-lobe lack apical spines and are shorter than half of its stalk on the aedeagal tube; the length covered by the cluster of spines is approximately half that of the smooth basal part on the aedeagal sac. However, in the latter species (Fig. 9 a), the arms of the Y-lobe are covered with apical spines and are obviously longer than half of its stalk on the aedeagal tube; the length covered by the cluster of spines is distinctly longer than that of the smooth basal part on the aedeagal sac.	en	Mo, Raorao, Lin, Aili, Li, Weihai (2025): Comprehensive review of the genus Neoperla (Plecoptera: Perlidae) from Guangdong, China: unveiling two new species and a new record.

6364974A6B1DFF95FF6EF98F4A2F63AA.taxon	distribution	Distribution. China: Guangdong (Zhaoqing City, Dinghushan Mountain (Ting-wu-shan )) Province. The type locality of the species, ' Ting-wu-shan, ' is very likely the Cantonese pronunciation (ding 6 wu 6 saan 1) of Dinghushan Mountain, which is located in the northeast of Zhaoqing City, Guangdong Province. Thus, we suspect that the discrepancy might be due to either an error in the Pinyin system or the use of an older romanization system by the collector. Additionally, due to the absence of aedeagal characteristics for this species, N. tingwushanensis is removed from the species list of Yunnan.	en	Mo, Raorao, Lin, Aili, Li, Weihai (2025): Comprehensive review of the genus Neoperla (Plecoptera: Perlidae) from Guangdong, China: unveiling two new species and a new record.

6364974A6B12FF9FFF6EFF33498B62E2.taxon	discussion	Remarks. The new species is similar to Neoperla anjiensis Yang & Yang, 1998 and N. shiwandashana Mo, Yao, Wang & Li, 2019 (Huo et al. 2021) in possessing similar terminalia and a simple, fully sclerotized aedeagal tube. The new species and N. anjiensis can be distinguished by comparing details of the aedeagal sac armature. In the new species (Figs. 5 d, 6 a – b), the aedeagal sac is strongly curved ventrally, forming a semicircular shape, and its dorsal surface is evenly covered with coarse spines of uniform size. In contrast, in N. anjiensis (Fig. 9 b), the aedeagal sac curves at a right angle towards the ventral surface, and its dorsal surface is covered with spines of varying sizes. In addition, the new species can be easily distinguished from N. shiwandashana by its significantly longer aedeagal sac. In N. shiwandashana (Fig. 9 c), the length of the aedeagal sac is approximately equal to the width of the aedeagal tube.	en	Mo, Raorao, Lin, Aili, Li, Weihai (2025): Comprehensive review of the genus Neoperla (Plecoptera: Perlidae) from Guangdong, China: unveiling two new species and a new record.
