J. Agr. Sci. Tech. (2019) Vol. 21(5): 1183-1197 New Addition to Sawflies (Hymenoptera: Symphyta) from Hyrcanian Forests in Northern Iran M. Khayrandish1*, and S. Farahani2 ABSTRACT The sawfly fauna (Hymenoptera: Symphyta) was studied in Hyrcanian Forests. The specimens were collected using Malaise traps during March to November 2016. Thirty- seven species of Symphyta were obtained from forest areas in Golestan and Mazandaran Provinces. Among them, five species were recorded for the first time from Iran: Fenella minuta (Dahlbom, 1835), Hoplocampa chrysorrhoea (Klug, 1816), Nematus glaphyropus Dalla Torre, 1882, Macrophya ribis (Schrank, 1781) and Phylloecus niger (M. Harris, 1779). The genus Fenella is newly recorded from Iran. General discussion is given for the sawfly fauna of Iran. Keywords: Genus Fenella, Pest management, Sawfly fauna. INTRODUCTION The suborder Symphyta is represented in West Palaearctic by more than 1350 species of the Tenthredinidae and about 440 species of Sawflies are the insects of the suborder other families (Taeger et al., 2010). The first Symphyta within the order Hymenoptera. published record of Iranian Symphyta was that Symphyta is cosmopolitan with more than by Konow (1888) who described “Allantus 8000 extant species of 8 superfamilies, 14 persa n. sp.” [= Tenthredo excellens (Konow, families, and 800 genera (Aguiar et al., 2013). 1886)] from Persien. Recently, several Sawflies are small to large sized insects and comprehensive studies have been done on recognizable from other members of sawflies in North of Iran by Khayrandish et al. Hymenoptera by very little or no constriction (2015, 2012, 2019), who described two new between the first and second abdominal species to science. In the checklist of Iranian segments and the forewing with numerus sawflies, 178 species belonging to 60 genera closed cells and veins. Sawfly larvae are of 9 families were listed (Khayrandish et al., Downloaded from jast.modares.ac.ir at 10:14 IRST on Monday September 27th 2021 phytophagous (except the parasitic family 2017). However, Iranian fauna of Symphyta Orussidae). They feed on various trees and has been insufficiently elucidated yet, and shrubs and can cause significant economic further studies are needed to increase our damage to agricultural crops and forests. Some knowledge on the taxonomy of Symphyta for species, especially in family Tenthredinidae, pest management and biodiversity are gall makers and internal feeders of leaves conservation. As part of an ongoing and fruits. Cephid larvae have the habit of comprehensive research on the sawfly in the boring into stalks and stems and siricid and forests of Iran, we surveyed the fauna of xiphydriid larvae feed on wood and tunnel in Symphyta species in Hyrcanian Forests. the substrate (Viitasaari, 2002). _____________________________________________________________________________ 1 Department of Plant Protection, Faculty of Agriculture, Shahid Bahonar University of Kerman, Kerman, Islamic Republic of Iran. 2 Research Institute of Forests and Rangelands, Agricultural Research Education and Extension Organization (AREEO), Tehran, Islamic Republic of Iran. *Corresponding author; e-mail: [email protected] 1183 ___________________________________________________________ Khayrandish and Farahani MATERIALS AND METHODS 2017); Alborz, Kermanshah, Kerman and Tehran Provinces (Khayrandish and Ebrahini, 2018).
