03C6FC4FFFD1B07BFF6B4BEDFBB38906.taxon	description	Figures 1 – 2 Male. General color yellowish brown (Fig. 1). Head pale brown, with a dark spot over the ocelli and a second small spot anteromedially on frons; The pronotum is nearly trapezoidal in shape, featuring pointed anterior angles and rounded posterior angles, with a slightly rough surface texture. Antennae and palpi yellow brown; legs pale brown except distal femora darker. Wing membrane brownish, veins brown. Body length 17 mm. Terga 1 – 6 unmodified. Tergum 7 features a posteromedial portion elevated into a broad, rectangular process that slightly extends rearward. This area exhibits a varied quantity and density of sensilla basiconica distributed across its surface. Tergum 8 possesses a slender, erect, and recurved medial tongue-like process, which is adorned with apical teeth. Tergum 9 is straightforward in structure and does not possess a sensilla patch. The hemitergal processes of tergum 10 are sclerotized, short, and exhibit a slight medial upward curve (Fig. 1). The penis tube is short and stout, featuring a spiny patch at the end of a weakly sclerotized area on its dorsal surface, with additional sclerotization evident on the ventral side near the base (Fig. 2). The endophallus is elongated and tubular, bending toward the ventral side. At the base on the ventral surface, there are a pair of spiny lobes. Additionally, on either side near the base of the endophallus, there is a membranous projection that is densely covered with spines on its dorsal surface. The entire endophallus is covered with very fine spines, while the spines on the dorsal surface are slightly larger. Additionally, six humps are located on the dorsal surface of the mid to posterior section of the endophallus. Female, egg, larva.

03C6FC4FFFD1B07BFF6B4BEDFBB38906.taxon	discussion	Remarks. The shape of the penis in N. spinistrumata sp. nov. closely resembles that of N. magisterchoui Du, 2000 (see figs. 6 – 11 in Li et al, 2011), with both species featuring spiny lobes on the ventral and lateral surfaces near the apex of the penis tube. However, N. spinistrumata sp. nov. can be distinguished from N. magisterchoui by the presence of six humps on the dorsal surface of the mid to posterior section of the endophallus. The taxonomic position of this species within the N. lushana - group is uncertain. While this group typically has paired spiny lobes or a single divided lobe ventrally on the aedeagus, N. spinistrumata possesses unique membranous projections near the endophallus base and is densely spined dorsally. This morphological distinction challenges its inclusion in the group and we tentatively exclude it from the N. lushana - group pending further study.	en	Zeng, Liang-Liang, Huo, Qing-Bo, Du, Yu-Zhou (2025): A new species and a new record of Neoperla Needham (Plecoptera: Perlidae) from Yunnan, China.

Zootaxa 5618 (3): 446-450, DOI: 10.11646/zootaxa.5618.3.10, URL: https://doi.org/10.11646/zootaxa.5618.3.10
03C6FC4FFFD2B07DFF6B4DA1FB848E06.taxon	discussion	Remarks. Originally described from Thailand by Stark (1983), this species exhibits prickly lines on the endophallus that closely resemble Stark's illustrations. Chiang Mai, located in northern Thailand, is nestled in a valley of the Mae Nam River basin and is surrounded by mountains, most notably the Doi Pui range. Pu'er is located in the southwestern part of Yunnan Province, and the straight-line distance between Chiang Mai and Pu'er is approximately 500 kilometers. Due to the presence of paired spiny lobes on the ventral surface near the apex of the penile tube in N. lahu, we classify it within the lushana - group (Zwick, 2023). Finally, we present clear color images for the first time, aiming to assist in the future identification of this species (Figs. 3 – 4).	en	Zeng, Liang-Liang, Huo, Qing-Bo, Du, Yu-Zhou (2025): A new species and a new record of Neoperla Needham (Plecoptera: Perlidae) from Yunnan, China.
