883E4F57C236F95AFF5FF8D3FE7BFBD1.taxon	diagnosis	Diagnosis and remarks. The new species is tentatively assigned to the N. oculata species complex sensu Zwick (1986) of the montivaga species group (Zwick 1983) because of its broad T 7 lobe and multiple lobes of the aedeagal sac. This species shares a similar head pattern with N. latispina Wang and Li, 2013 from the Guangxi Zhuang Autonomous Region of southern China (fig. 1 in Wang et al. 2013). However, the dorsolateral lobes of the aedeagal tube in the new species are small but those of N. latispina form enlarged dorsolateral projections. Additionally, the pair of mesolateral protrusions present on the aedeagal sac of N. latispina are rounded, whereas the corresponding patches of N. baisha are much larger and extended toward the apex (compare fig. 2 in Wang et al. 2013 and Figs. 1 d, 2).	en	Kong, Fanbin, Lv, Junfeng, Li, Weihai (2014): Three new species of Neoperla in the montivaga group (Plecoptera: Perlidae) from China.

883E4F57C235F95DFF5FFB3DFEACFF30.taxon	description	Male. Forewing length 9.2 – 9.3 mm. General body color yellow brown. Distance between ocelli narrower than diameter of the ocellus. Head brownish with dark brown area between ocelli (Fig. 3 a); compound eyes black; antennae brown and mouthparts brownish. Pronotum pale brown with brownish markings (Fig. 3 a); wing membrane brownish, veins darker; legs brownish. Abdominal segments pale brown, terminalia processes and cerci dark brown. Terminalia. Tergum 7 with posterior margin produced into a triangular process, covered with many marginal sensilla basiconica (Figs. 3 b, 3 d). Tergum 8 with no process but covered by small median spine patch (Fig. 3 b). Tergum 9 without patches of sensilla basiconica or long hairs. Hemitergal processes of tergum 10 strongly sclerotized and finger-like, with a median curve and sharp tip (Figs. 3 b, 3 d). Aedeagal tube with heavily sclerotized dorsal band and apical and subapical ventral spinose projections (Fig. 3 c). Aedeagal sac narrow at basal half and swollen apically, with spinules on most of the surface except the apical one fifth; the entire aedeagus exhibits a double curve, showing in lateral aspect, an S-shaped curve (Figs. 3 c, 4).

883E4F57C235F95DFF5FFB3DFEACFF30.taxon	diagnosis	Diagnosis and remarks. The male of the new species is characterized by the aedeagal tube having apical and subapical ventral spinose projections which distinguish this species from all others in the montivaga group. The aedeagal armature is superficially similar to that of N. reticulata Zwick (1986) described from Borneo, but in that species there are two distal patches of spines located ventrolaterally, and a single proximal spine patch set on a small ventral lobe.	en	Kong, Fanbin, Lv, Junfeng, Li, Weihai (2014): Three new species of Neoperla in the montivaga group (Plecoptera: Perlidae) from China.

883E4F57C232F951FF5FF919FC07FE80.taxon	description	Male. Forewing length 8.7 mm. General body color yellowish brown. Distance between ocelli narrower than diameter of the ocellus. Head brownish, with a Y-shaped dark area between ocelli and M line and a small triangular spot on the anterior frons (Fig. 5 a); compound eyes and ocelli black; antennae and mouthparts brownish. Pronotum pale with indistinct markings (Fig. 5 a); wing membrane subhyaline, veins brown; legs brownish. Abdominal segments pale brown, terminalia processes and cerci dark brown. Terminalia. Process of tergum 7 small and triangular, covered by many marginal sensilla basiconica (Figs. 5 b, c). Tergum 8 with a median patch of small spines (Fig. 5 b). Tergum 9 with two patches of sensilla basiconica. Hemitergal processes of tergum 10 strongly sclerotized and finger like, with a slight median curve. Aedeagal tube with sclerotized dorsal band and a pair of dorsoapical spinose projections (Fig. 5 d). Aedeagal sac nearly parallel sided, with spinules on most of the surface except the apical with an incomplete ring of large spines; an elongate basoventral projection with spinose apex and an apical membranous narrow one also present (Figs. 5 d, 6).

883E4F57C232F951FF5FF919FC07FE80.taxon	diagnosis	Diagnosis and remarks. The male of new species is characterized by a very elongate ventral aedeagal projection and two small dorsal spinulose lobes and an incomplete spinose ring at apex of sac. Therefore, this species is tentatively assigned to the N. oculata species complex and seems similar to the Bornean N. divergens Zwick 1986 (figs. 62 – 63 in Zwick 1986). Neoperla furcomaculata has a basoventral projection with spinose apex but without subapical protrusions whereas the sac of N. divergens has several subapical protrusions and swellings in addition to the basoventral spinose projection (Fig. 63 in Zwick 1986).	en	Kong, Fanbin, Lv, Junfeng, Li, Weihai (2014): Three new species of Neoperla in the montivaga group (Plecoptera: Perlidae) from China.
