Diversity and Distributional Patterns of Stoneflies (Insecta: Plecoptera) in the Aquatic Ecosystems of Serbia (Central Balkan Peninsula)
2014Co-Authors: Petrovic Ana, Simic Vladica, Milosevic Djuradj, Paunović Momir, Sivec IgnacAbstract:This work contributes to the knowledge of the fauna of Plecoptera (Insecta) of the Central Balkan Peninsula. A total of 90 species analysed in this study belong to 17 genera and 7 families. The largest number of stonefly species was recorded within the Juzna and Zapadna Morava River Basins and the rivers belonging to the Aegean Sea Basin (Pcinja, Dragovistica and Lepenac), while the lowest taxa richness was observed within the rivers Kolubara and Velika Morava, as well as from the Danube River. Based on the IUCN criteria, 10 species were classified as important from conservational point of view: Marthamea vitripennis, Protonemura lateralis and Taeniopteryx hubaulti as Critically Endangered, Dinocras mega-cephala, Nemoura cambrica, Protonemura meyeri, Protonemura praecox and Taeniopteryx nebulosa as Endangered, and Amphinemura sulcicolis and Perlodes microcephalus as Vulnerable.Ministry of Education and Science of the Republic of Serbia {[}43002, 31011

The first two mitochondrial genomes from Taeniopterygidae (Insecta: Plecoptera): Structural features and phylogenetic implications.
International Journal of Biological Macromolecules, 2017Co-Authors: Zhi-teng Chen, Yuzhou DuAbstract:Abstract The complete mitochondrial genomes (mitogenomes) of Taeniopteryx ugola and Doddsia occidentalis (Plecoptera: Taeniopterygidae) were firstly sequenced from the family Taeniopterygidae. The 15,353-bp long mitogenome of T. ugola and the 16,020-bp long mitogenome of D. occidentalis each contained 37 genes including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and a control region (CR). The mitochondrial gene arrangement of the two taeniopterygids and other stoneflies was identical with the putative ancestral mitogenome of Drosophila yakuba. Most PCGs used standard ATN start codons and TAN termination codons. Twenty-one of the 22 tRNAs in each mitogenome could fold into the cloverleaf secondary structures, while the dihydrouridine (DHU) arm of trnSer (AGN) was reduced or absent. Stem-loop (SL) structures, poly-T stretch, poly-[AT]n stretch and tandem repeats were found in the CRs of the two mitogenomes. The phylogenetic analyses using Bayesian inference (BI) and maximum likelihood methods (ML) generated identical results, both supporting the monophyly of all stonefly families and the two infraorders, Systellognatha and Euholognatha. Taeniopterygidae was grouped with another two families from Euholognatha. The relationships within Plecoptera were recovered as (((Perlidae + Peltoperlidae) + ((Pteronarcyidae + Chloroperlidae) + Styloperlidae)) + ((Capniidae + Taeniopterygidae) + Nemouridae)) + Gripopterygidae.

reanalysis and experimental evidence indicate that the earliest trace fossil of a winged insect was a surface skimming neopteran
Evolution, 2013Co-Authors: James H MardenAbstract:A recent description and analysis of an imprint fossil from the Carboniferous concluded that it was made by a mayfly landing in sediment at the edge of water. Here, I reanalyze that trace fossil and supply experimental evidence regarding wing traces and behavior. The thorax of the trace maker lacked structures characteristic of mayflies, but closely matches a modern neopteran insect family (Taeniopterygidae, Plecoptera) little changed from Early Permian fossils. Edges of the folded wings of live Taeniopteryx leave marks on sediment closely matching marks in the trace fossil. Faint marks lateral to and beyond the reach of meso- and metathoracic legs match the location where wings of surface-skimming Taeniopteryx stoneflies lightly touch the sediment when these insects skim onto wet ground at shorelines. Dimensions of the thorax of the trace indicate relatively weak flight ability compared to fossils from the Early Permian, making doubtful the hypothesis that the trace maker was flight capable. Ultimately, this fossil best fits a scenario in which a neopteran insect skimmed across the surface of water, then folded its wings. Surface skimming as a precursor to the evolution of flight in insects is supported by this fossil evidence of skimming behavior in a Carboniferous insect.

diversity of stonefly hexamerins and implication for the evolution of insect storage proteins
Insect Biochemistry and Molecular Biology, 2007Co-Authors: Silke Hagnerholler, Christian Pick, Stefan Girgenrath, James H Marden, Thorsten BurmesterAbstract:Hexamerins are large storage proteins of insects in the 500 kDa range that evolved from the copper-containing hemocyanins. Hexamerins have been found at high concentration in the hemolymph of many insect taxa, but have remained unstudied in relatively basal taxa. To obtain more detailed insight about early hexamerin evolution, we have studied hexamerins in stoneflies (Plecoptera). Stoneflies are also the only insects for which a functional hemocyanin is known to co-occur with hexamerins in the hemolymph. Here, we identified hexamerins in five plecopteran species and obtained partial cDNA sequences from Perla marginata (Perlidae), Nemoura sp. (Nemouridae), Taeniopteryx burksi (Taeniopterygidae), Allocapnia vivipara (Capniidae), and Diamphipnopsis samali (Diamphipnoidae). At least four distinct hexamerins are present in P. marginata. The full-length cDNA of one hexamerin subunit was obtained (PmaHex1) that measures 2475 bp and translates into a native polypeptide of 702 amino acids. Phylogenetic analyses showed that the plecopteran hexamerins are monophyletic and positioned at the base of the insect hexamerin tree, probably diverging about 360 million years ago. Within the Plecoptera, distinct hexamerin types evolved before the divergence of the families. Mapping amino acid compositions onto the phylogenetic tree shows that the accumulation of aromatic amino acids (and thus the evolution of ‘‘arylphorins’’) commenced soon after the hexamerins diverged from hemocyanins, but also indicates that hexamerins with distinct amino acid compositions reflect secondary losses of aromatic amino acids. r 2007 Elsevier Ltd.

A stonefly species extinct in Europe ( Taeniopteryx araneoides Klapalek, 1902, Taeniopterygidae, Plecoptera) is thriving in the Irtysh River in West Siberia and North Kazakhstan.
Zootaxa, 2017Co-Authors: Oleg E. Kosterin, Nazymgul Akimbekova, Vladimir V. Dubatolov, Ignac SivecAbstract:Taeniopteryx araneoides Klapalek, 1902, a stonefly species with brachypterous males, known historically from the Danube, Elbe, and Dniester rivers, but considered to be extinct at least in Europe for more than a century. This species has also been doubtfully reported from Krasnoyarsk, Central Siberia. However, we report this species to be still thriving in the Irtysh River at the cities of Omsk (West Siberia, Russia) and Pavlodar (North Kazakhstan). The occurrence of this species reported least fifty years ago from the Yenisey River at Krasnoyarsk, Russia is considered possible. Unlike the widespread Palaearctic T. nebulosa (Linnaeus, 1758) that occurs in a broad range of stream types, T. araneoides is a potomon species, apparently confined to large rivers. In this habitat, it appears vulnerable to anthropogenic impacts and may be unable to compete with T. nebulosa . The construction of dams and reservoirs has apparently extirpated T. araneoides from most of its former geographical range.
