Abstract: The European Rhogogaster s. str. species are revised, and several nominal taxa from Asia discussed. The taxonomic identity of the type species Tenthredo viridis Linnaeus, 1758 is different from that assumed in the past. Tenthredo dryas Benson, 1943 is syn. nov. of R. viridis. The name Rhogogaster scalaris (Klug, 1817), species revocata, is to be applied to Rhogogaster viridis auct. New subjective junior synonyms of R. scalaris (Klug, 1817) are R. chlorosoma podkumokensis Muche, 1973, syn. nov. and Tenthredo (Rhogogaster) carpatica Zhelochovtsev & Zinovjev, 1988, syn. nov. Rhogogaster magniserrula Viitasaari, spec. nov. is described from Finland and Russia. The former synonym of R. viridis auct., Tenthredo hebraica Geoffroy in Fourcroy, 1785, is treated as species incertae sedis within Rhogogaster. The Asian Rhogogaster viridis var. sibirica Enslin, 1912, is regarded as a valid species, Rhogogaster sibirica Enslin, 1912, stat. nov., and Rhogogaster kudiana Rohwer, 1925, is a subjective syn. nov. of R. sibirica. A key to the European Rhogogaster s. str. with special emphasis on Fennoscandia is given.The following nominal taxa are excluded from Rhogogaster: Rhogogaster viridis forma montana Betrem, 1933, is syn. nov. of Tenthredo olivacea Klug, 1817; Sciapteryx virescens Jakowlew, 1887, is Tenthredo (Eurogaster) virescens (Jakowlew, 1887), comb. nov.; Tenthredo interrupta Fabricius, 1804 (nomen oblitum) is syn. nov. of Tenthredopsis tessellata (Klug, 1817) (nomen protectum). Tenthredo viridis Poda, 1761, Tenthredo straminea Schrank, 1776, Tenthredo annalicornis [sic!] Gmelin, 1790, and Tenthredo chloros Rudow, 1871 are considered to be species incertae sedis within Tenthredinidae.Lectotypes are designated for Tenthredo interrupta Fabricius, 1804, Sciapteryx virescens Jakowlew, 1887, Sciopteryx gilva Konow, 1908, Rhogogaster viridis var. sibirica Enslin, 1912, R. viridis forma montana Betrem, 1933, R. chlorosoma podkumokensis Muche, 1973, R. genistae viridifrons Muche, 1973 and Tenthredo (Rhogogaster) carpatica "Bokotey" [= Zhelochovtsev & Zinovjev], 1988.
TL;DR: The first records from Sweden of 15 species of sawfly are presented: 2 species of Pamphiliidae,1 Argidae, 11 Tenthredinidae and 1 Cimbicidae.
Abstract: The first records from Sweden of 15 species of sawfly are presented: 2 species of Pamphiliidae,1 Argidae, 11 Tenthredinidae and 1 Cimbicidae. Of these, Empria camtschaticaand E. plana are also recorded for the first time in Europe. An illustrated key is providedto distinguish them from similar species (E. immersa, E. fletcheri). Rhogogaster polarisLindqvist, 1964 is treated as a valid species (species revocata). The number of Symphytaspecies that occur in Sweden and possible deficits in recording strategies are discussed.
TL;DR: The first results of sawfly fauna investigations are presented, including a new species for the Russian fauna, as well as a new genus of sawflies, in the Mordovia State Nature Reserve.
Abstract: Introduction The Mordovia State Nature Reserve is located in the Temnikov district of the Republic of Mordovia. It belongs to the Central Russian subprovince of the Eastern European province of the broad-leaved forest region on the wooded right bank of the River Moksha. The forest-steppe naturally marks the boundary of the protected area from the south (Khapugin et al., 2016). The climate of the Mordovia State Nature Reserve is related to the Atlantic continental region of the temperate zone. Intensive entomological studies in recent years have shown many new and interesting features of Insecta species in the Mordovia State Nature Reserve area (Ruchin & Artaev, 2016; Ruchin & Lengesova, 2012; Ruchin & Egorov, 2018; Tomaszewska et al., 2018). The genus Rhogogaster Konow, 1884 (type species – Tenthredo viridis Linnaeus, 1758) is represented by a group of green sawflies, which are quite well isolated from the outwardly close genus of Tenthredo Linnaeus, 1758. Taeger et al. (2010) recorded 40 species of Rhogogaster s.l. worldwide, and placed seven of these in Rhogogaster s.str. and six in Cytisogaster. The remaining 27 species were left unplaced within the genus. In this report, the first results of sawfly fauna investigations are presented, including a new species for the Russian fauna.
TL;DR: Six proposed species-groups of the genus Rhogogaster are proposed, and two new species of the viridis group are described from males and females taken Afghanistan and Turkey.
Abstract: SYNOPSIS
Keys are given to six proposed species-groups of the genus Rhogogaster, and to the species of each group. Two new species of the viridis group are described from males and females taken Afghanistan and Turkey.
