Zwicknia gen. n., a new genus for the Capnia bifrons species group, with descriptions of three new species based on morphology, drumming signals and molecular genetics, and a synopsis of the West Palaearctic and Nearctic genera of Capniidae (Plecoptera)

Zwicknia Murányi, gen. n. is erected for the Capnia bifrons species group sensu Zhiltzova, 2001 with the description of three new species based on morphology, mating call, and the mitochondrial DNA marker cytochrome c oxidase I: Z. acuta Murányi & Orci, sp. n., Z. kovacsi Murányi & Gamboa, sp. n. and Z. rupprechti Murányi, Orci & Gamboa, sp. n.. Zwicknia bifrons (Newman, 1838) comb. n. is selected as the type species and redescribed. The other three species placed into Zwicknia, gen. n., Z. sevanica (Zhiltzova, 1964) comb. n., Z. tuberculata (Zhiltzova, 1964) comb. n., and Z. turkestanica (Kimmins, 1950) comb. n. are redescribed based only on morphological characters. Comparative morphological studies and newly discovered characters of the genitalia has allowed for the first time a synopsis of the adults of the West Palaearctic and Nearctic genera of Capniidae. Arsapnia Banks, 1897 (type species: A. decepta Banks, 1897 comb. rev.) is removed from synonymy with Capnia Pictet, 1841 with new combinations, Arsapnia arapahoe (Nelson & Kondratieff, 1988) comb. n., A. coyote (Nelson & Baumann, 1987) comb. n., A. pileata (Jewett, 1966) comb. n., A. sequoia (Nelson & Baumann, 1987) comb. n., A. teresa (Claassen, 1924) comb. n., A. tumida (Claassen, 1924) comb. n., and A. utahensis (Gaufin & Jewett, 1962) comb. n. A new sensu stricto diagnosis of Capnia is proposed with comments on the taxa retained in Capnia sensu lato.

Stoneflies of the genus Neoperla (Plecoptera, Perlidae) from Wuyi Mountain National Nature Reserve, Fujian of China

Abstract The species of the genus Neoperla are reviewed from Wuyi Mountain National Nature Reserve located in the Fujian Province of southeastern China, including the description of a new species, Neoperla brevistyla sp. n. The new species is compared to similar taxa. The first records of five Neoperla species, Neoperla henana Li, Wu & Zhang, 2011, Neoperla similiserecta Wang & Li, 2012, Neoperla qingyuanensis Yang & Yang, 1995, Neoperla xuansongae Li & Li, 2013 and Neoperla tuberculata Wu, 1938 are given for the Wuyi Mountain. A provisional key is provided for facilitating the identification of these species.

New and little known species of Nemouridae (Plecoptera) from Inner Mongolia of China

Four species of the family Nemouridae, Amphinemura helanshana sp. n., A. didyma Zhu & Yang, Nemoura geei Wu, and Nemoura cf. securigera Klapálek were collected during a two years survey of the Helan Mountains of Inner Mongolia, China. Nemoura cf. securigera has not been collected for more than one hundred years.

Revision of the Rhabdiopteryx neglecta species group (Plecoptera: Taeniopterygidae)

In the genus Rhabdiopteryx (Klapálek, 1902), the neglecta group sensu Illies 1957 forms a well distinguished set of species. In the male, the group is characterised by the ninth sternite subgenital plate being slightly depressed in the middle of its hind margin and by the very peculiar shape of the epiproct. The anterior process is a prong with bifid tip, and the posterior process has a stout base prolonged by two curved lateral arms. Even the females clearly differ in their postgenital plate widely covering the paraprocts. This group comprises three species: R. neglecta (Albarda, 1889), R. alpina Kühtreiber, 1934 and R. harperi sp. n. which are compared and illustrated by SEM photos. R. doiranensis Ikonomov, 1983 is removed from the neglecta group.

An annotated checklist of the Greek Stonefly Fauna (Insecta: Plecoptera)

An overview of the Greek stonefly (Plecoptera) fauna is presented as an annotated index of all available published records. These records have resulted in an updated species list reflecting current taxonomy and species distributions of the Greek peninsula and islands. Currently, a total of 71 species and seven subspecies belonging to seven families and 19 genera are reported from Greece. There is high species endemicity of the Leuctridae and Nemouridae, particularly on the Greek islands. The endemics known from Greece comprise thirty species representing 42% of the Greek stonefly fauna. The remaining taxa are typical Balkan and Mediterranean species.

New species records of Suwallia Ricker, 1943 (Plecoptera: Chloroperlidae) from China, with description of the nymph of S. decolorata Zhiltzova & Levanidova, 1978

Two species of the chloroperlid genus Suwallia, S. decolorata Zhiltzova & Levanidova, 1978 and S. talalajensis Zhiltzova, 1976 are reported for the first time from the Inner Mongolia Autonomous Region of China. The habitus and diagnostic features of these two species including aedeagal structures are illustrated with color images. Additional descriptions and taxonomic notes are provided. The nymph of S. decolorata is described.

A new genus and species of winter stoneflies (Plecoptera: Capniidae) from Southwest China, with a commented checklist of the family in the Oriental Realm.

A new genus and species of the family Capniidae (Plecoptera), Sinocapnia kuankuoshui gen. n., sp. n. is described from the adult male and a female collected in Guizhou Province of southwest China. The new taxon is distinguished from all extant Capniidae genera and the assemblage of species currently included in Capnia sensu lato by combination of unique genitalic, wing, and thoracic sclerites characters. No closely related taxon is indicated on the basis of morphological characters. An annotated checklist of the family Capniidae from the Oriental Realm is given.

Two new species of dark Neoperla (Plecoptera: Perlidae) from Oriental Realm of China.

Two new species of the perlid genus Neoperla, N. tadpolata Li & Murányi, sp. nov. and N. yunnana Li & Wang, sp. nov. are proposed from Guangxi Zhuang Autonomous Region and Yunnan Province of China, respectively. They are both typical members of the N. montivaga species group and the taxonomic relationships are discussed with related congeners of the group.

Molecular phylogeny and diversification timing of the Nemouridae family (Insecta, Plecoptera) in the Japanese Archipelago

The generation of the high species diversity of insects in Japan was profoundly influenced by the formation of the Japanese Archipelago. We explored the species diversification and biogeographical history of the Nemouridae family in the Japanese Archipelago using mitochondrial DNA and nuclear DNA markers. We collected 49 species among four genera: Indonemoura, Protonemura, Amphinemura and Nemoura in Japan, China, South Korea and North America. We estimated their divergence times—based on three molecular clock node calibrations—using Bayesian phylogeography approaches. Our results suggested that Japanese Archipelago formation events resulted in diversification events in the middle of the Cretaceous (<120 Ma), speciation in the Paleogene (<50 Ma) and intra-species diversification segregated into eastern and western Japan of the Fossa Magna region at late Neogene (20 Ma). The Indonemoura samples were genetically separated into two clades—that of Mainland China and that of Japan. The Japanese clade clustered with the Nemouridae species from North America, suggesting the possibility of a colonisation event prior to the formation of the Japanese Archipelago. We believe that our results enhanced the understanding both of the origin of the species and of local species distribution in the Japanese Archipelago.

A new species of Cryptoperla Needham, 1909 (Plecoptera: Peltoperlidae) from Guangxi of China, based on male, female, and larval stage

The present discovery represents the first record of the family Peltoperlidae in Guangxi. The distribution of its congeners is illustrated on a map.
