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.
ABSTRACT The distribution of the genus Paraleuctra (Hanson, 1941) in Canada, based on the examination of specimens in the Canadian National Collection of Insects, Arachnids and Nematodes, the ...University of Guelph Barcode of Life Data System website collection, and the Royal British Columbia Museum is presented. Most of the specimens in the Canadian National Collection of Insects, Arachnids and Nematodes (CNC; Ottawa, Ontario, Canada) were examined before the descriptions of R vershina and R alta. None of the specimens in the CNC, University of Guelph (UOG; Guelph, Ontario, Canada) Barcode of Life Data System (BOLD) collection, Royal British Columbia Museum collection (RBCM; Victoria, British Columbia, Canada), or the Illinois Natural History Survey (INHS; Champaign, Illinois, United States of America) were included in Stewart and Oswood (2006). Detailed collection data and photographs for specimens examined are also available at the following websites: the CNC online database (http://www.cnc-ottawa.ca/taxonomy/ SpecSearchD15.php) and the University of Guelph as part of the BOLD website (UOG) database, (http://v4.boldsystems.org/index.php/Public_BINSearch? searchtype=records; Ratnasingham and Hebert 2007).
We recently examined specimens of the genus
Hanson, 1941, from Zhejiang Province and Sichuan Province, China, and two new synonyms are established based on morphological and molecular data.
Yang and ...Yang, 1995, and
Li and Yang, 2010, are synonymized with
(Chu, 1928). Additionally, we provide new images of
Du and Qian, 2012, to facilitate identification of this species.
The species of Leuctridae (Plecoptera) from Guangxi, China are reviewed. Two species of Rhopalopsole are described as new to science, R. cestroidea sp. nov. and R. triangulis sp. nov., belonging to ...the R. vietnamica group and the R. magnicerca group, respectively. Six species of Leuctridae are now known for Guangxi including two additional species of Rhopalopsole and one Paraleuctra recorded for the first time. The previously unknown female of R. duyuzhoui Sivec & Harper, 2008 is described from specimens from Guangxi. Characters are illustrated for the separation of R. furcospina (Wu, 1973) and R. sinensis Yang & Yang, 1993. Mitochondrial sequences of five Rhopalopsole species support their specific recognition.
The pharate larval stage of Paraleuctra tianmushana Li & Yang is described for the first time. The yellowish-brown larvae of this species are characterized by a slender abdomen lacking setae and a ...unique pattern of dark pigmentation on the head, pronotum, and abdominal terga. Additionally, vestigial cervical gills in this species are present, a character not present in known Nearctic species.
Wuyi Mountains are located in the northern Oriental Region and the edge of the southern Palaearctic Region. They have a unique geographical location, complex landform and superior climatic ...conditions, providing a good ecological environment for Leuctridae species. However, due to the damage of some holotypes in the 20
century, limited drawings and lack of colour figures, it is necessary to reorganise and supplement the preserved Leuctridae specimens from Wuyi Mountains.
In this study, we found that there are twelve species of Leuctridae recorded in Wuyi Mountains, accounting for about 20% of the recorded species of Leuctridae in China. These records include two genera and five new distribution records species: one species of the genus
Hanson, 1941:
(Chu 1928) and eleven species of the genus
Klapálek, 1912, including five new distribution records to Wuyi Mountains:
Yang, Shi & Li, 2009;
Yang & Yang, 1993;
Sivec & Harper, 2008;
Yang & Yang, 1995;
Yang & Yang, 1995. Now a total of twelve species of Leuctridae have been recorded from Wuyi Mountains, Fujian Province of south-eastern China. In this paper, we also provide a key to the male, new images and some notes of these twelve species, except
(Wu, 1949) and
(Wu, 1949). We failed to collect these two species and we regard
as a nomen dubium, because there are no distinctive features that can be used to distinguish this species.
A new species of the genus Paraleuctra, P. qilianshana sp. nov., is described from Mt. Qilianshan, Gansu Province, China. The new species is the first representative of Paraleuctra discovered in the ...Palearctic Region of China. The new species is compared with its regional congeners.
A new species, Paraleuctra cervicornis Du and Qian, from Sichuan, China is described and a key to males of four Chinese Paraleuctra is presented. Types of the new species are deposited in the Insect ...Collection of Yangzhou University.
The impacts of co-occurring stressors (river regulation by a dam and mine drainage) on hyporheic macroinvertebrate assemblages and environmental variables were investigated in a mountainous area of ...central Colorado at seven sampling sites in Lake Fork during two different seasons. Specific aquatic macroinvertebrate assemblages were associated with river regulation and trace element impacts.
Paraleuctra was primarily associated with mining impacted sites, while
Polycelis,
Hydra, and
Simulium were most abundant at sites nearest the dam. There were sometimes large differences in toxicity between hyporheic and surface water samples. Occasionally toxicity was present in the surface water, but absent in hyporheic water from the same site, while on one date, toxicity was detected in the hyporheic but undetected in surface water. The distinct taxa found in the hyporheic, and differences between hyporheic and surface water quality suggest that understanding the hyporheic zone is important in the study of impacted aquatic systems.
