Filchneria heteroptera (Wu, 1938) is rediscovered from Heilongjiang Province of northeastern China. A supplementary description and illustrations including aedeagal structures based on newly ...collected specimens are provided. Filchneria dongruihangi Chen, 2020 is considered here as a junior synonym of F. heteroptera (Wu, 1938). Paraleuctra cercia (Okamoto, 1922) is reported from Liaoning and Heilongjiang provinces, China for the first time.
The larval morphology of Plecoptera is relatively insufficient in comparison with their adults. In this study, the larvae of Neofilchneria wanglanga Chen, 2019 and Skwala compacta (McLachlan 1872) ...from the family Perlodidae are described and illustrated based on specimens from China. The larvae of N. wanglanga and S. compacta share very similar body color patterns. Their morphological differences mainly concern the chaetotaxy of each body part and the structure of abdominal segments. Two DNA barcoding sequences are provided for the widespread S. compacta. Larval morphology provided in this study will promote the larval taxonomy and full-evidence phylogeny of Perlodidae and Plecoptera.
Klapálek, 1912 is a small stonefly genus in the Palearctic areas of China and its biodiversity is underestimated.
This paper reports a new species of
,
sp. nov. in the Dajiuhu National Wetland Park ...of Shennongjia Forestry District, Hubei Province, central China. The description and illustrations of the new species are provided, based on male adults, female adults and eggs. The new species can be distinguished from its congeners by the characters of male and female genitalia and the egg structure.
To obtain a better understanding of the mitochondrial genome in Perlodidae and the phylogeny of Perloidea, we sequenced two perlodid mitochondrial genomes and present comparative analyses in the ...family Perlodidae. Our results show that genome organization, base composition, codon usage and non-coding and overlapping regions, the sequences of mitochondrial transcription termination factor (DmTTF) and structural elements in control region were conserved in Perlodidae. The unique non-coding regions in COI-trnL2 and trnL2-COII were present in Perlodidae but were incomplete or absent from other stoneflies, and we also discuss the conservative property of the sequences between trnE and trnF, trnS1 and ND1. The secondary structure of tRNAs showed that the trnK, trnP, trnS1 and trnW were identical and the trnS1 could not be folded into typical secondary structure due to its absence of DHU arm. Phylogenetic implications supported that Chloroperlidae is a sister group to Perlodidae and the Perlidae is a sister group to the clade Chloroperlidae + Perlodidae. This study contributes to understanding the comparative mitogenomic analysis of Perlodidae and phylogenetic relationships within the Perloidea.
•Genome features were conserved in Perlodidae.•G + C-rich block and stem-loop structure were founded in control region of two Perlodid species.•The monophyly of Perloidea is well supported by our result.•The position of Perlodidae, Chlorperlidae and Perlidae supports the traditional morphology-based classification.
Stavsolus shihu sp. n., a new species of stonefly family Perlodidae is described from the Jilin Province of China, illustrated and compared with the related taxa. Habitat data of the new species are ...given.

Perlodinella microlobata Wu, 1938 is rediscovered in Qinghai and Sichuan provinces with a supplementary description in this paper. Another species collected from Qinghai at the same time, ...Tibetisoperla sclerotica Yan, Chen, Bozdogan & Li, 2022, is partially revised because the adult female belongs to the chloroperlid genus Sweltsa Ricker, 1943.
Five Filchneria Klapálek, 1908 (Plecoptera, Perlodidae) species known since the last century (F. balcarica Balinsky, F. mesasiatica Zhiltzova, F. irani (Aubert), F. kuenluensis (Šámal), and F. olgae ...(McLachlan)) were redescribed on types stored in museums in the Netherlands, Switzerland, Russia and newly acquired material. The redescription were in accordance with the requirements of modern taxonomy, illustrated with color photographs of the habitus, head, pronotal patterns, eversible male paraproct lobes, male paraproctal sclerite, aedeagus (as possible), details of chaetotaxy, female subgenital plate, and egg using digital cameras and SEM. The diagnostic features of each species are revealed. The main differences were established in the male paraproctal sclerite shape, in the posterior margin of tergum 10, the female subgenital plate, and the egg structures. After reexamining the syntype series of Filchneria olgae, a lectotype is designated for this species. Filchneria kuenluensis is proposed to transfer to Perlodinella Klapálek, 1912 with the valid name Perlodinella kuenluensis (Šámal, 1935) comb. nov. Filchneria shobhaae is considered as a junior synonym of Zhiltzovaia amabilis (Jewett, 1958) syn. nov.
The larva of the Balkan microendemic Isoperla vevcianensis Ikonomov, 1980 (Plecoptera: Perlodidae: Isoperlinae) is described on the basis of larvae associated with adults by means of cox1 sequences ...similarities. Eggs and everted penis of the male are described for the first time. The larva possessed blunt paraprocts which were previously sharp among Palaearctic larvae of this huge Holarctic and Oriental genus. The commonly pointed paraproct remains as the only distinguishing generic character for the morphologically diverse larvae of Palaearctic Isoperla, but should not be considered as an exclusive character state for the genus. Morphological characters are illustrated in comparison with the sympatric larvae of the Isoperla tripartita species complex.
Isoperla riverae sp. n. is described from the southeastern USA. The new species is proposed based on details of the adult habitus, male aedeagus, vesicle, female subgenital plate, ovum chorion, and ...larval habitus. Supporting data includes color images, scanning electron micrographs, genetic analysis of DNA barcodes, and comparative morphology of cognate species. The larva of Isoperla lenati Szczytko & Kondratieff, 2015 is also described supported by color images.
A new brachypterous species of Perlodidae, Filchneria urumqiensis sp. n., from Xinjiang Uygur Autonomous Region of northwestern China is described and illustrated based on male, female and eggs. ...Morphological comparisons with the related taxa and habitat information of the new species are provided.
