ABSTRACT. Three Phyllonorycter species namely, Ph. coryli (Nicelli, 1851), Ph. millierella (Staudinger, 1871) and Ph. roboris (Zeller, 1839) are newly reported for the fauna of Iran. These species are collected in Azarbaijan-e Received: Sharghi, Tehran and Kordestan provinces, respectively. The first two species 25 December, 2017 were collected as larvae while feeding on Carpinus betulus L. (Betulaceae) and Celtis australis L. (Cannabaceae), in the order, and the last one collected as Accepted: 03 February, 2018 adult in an Oak forest using light trap. The genus Carpinus L. and C. betulus are newly reported as larval host plant for Ph. coryli. Brief taxonomic Published: characterizations of these species are provided and an updated list of the 04 February, 2018 Phyllonorycter species occurring in Iran is presented.

Introduction The family Gracillariidae constitutes the of the Phyllonorycter species are strictly main plant mining family of Lepidoptera monophagous (Robinson et al., 2001, 2002, (Davis, 1987) and includes almost 2000 2010; De Prins & De Prins, 2005, 2017) and known species in 100 genera (van their larvae feed internally on living plant Nieukerken et al., 2011; De Prins & De tissues. The larval instars are devouring the Prins, 2017). The most species-rich genus of parenchyma cells, making tentiform mines this family, Phyllonorycter Hübner, 1822 on upper or lower surfaces and undergoing (syn., Lithocolletis Hübner, 1825) is assigned all their pre-imaginal stages including the to the subfamily Lithocolletinae and pupa within a mine (Emmet et al., 1985; comprises 401 described species (De Prins Davis & Robinson, 1998). As our & De Prins, 2017). This genus has a knowledge goes, 112 plant genera from 31 worldwide distribution with the greatest different families, 15 orders, and six diversity in the Palaearctic Region (257 subclasses have been recorded as food species) (De Prins & De Prins, 2017). Most plants of the Phyllonorycter species (Lopez- Corresponding author: Helen Alipanah, E-mail: [email protected] Copyright © 2018, Alipanah & Farahani.

This species was 2017). identified as Ph. roboris (Zeller, 1839). These Little is known about the Gracillariidae three species are newly reported for the of Iran and up to 20 species in 10 genera and fauna of Iran. Moreover, this is the first five subfamilies namely, Acrocercopinae record of the genus Carpinus and C. betulus Kawahara & Ohshima, 2016, Gracillariinae L. as the larval host plant for Ph. coryli. In Stainton, 1854, Lithocolletinae Stainton, the present study brief characterizations of 1854, Parornichinae Kawahara & Ohshima, these species are provided and an updated 2016, and Phyllocnistinae Herrich-Schäffer, list of the Phyllonorycter species occurring in 1857 have been reported from Iran so far. Iran is presented. The recorded species are belonging to the Material and methods genera: Acrocercops Wallengren, 1881 (one species), Aspilapteryx Spuler, 1910 (three The specimens of Ph. coryli and Ph. species), Caloptilia Hübner, 1825 (one millierella were collected as larvae in species), Calybites Hübner, 1822 (one Arasbaran forest (Azarbaijan-e Sharghi species), Cupedia Klimesch & Kumata, 1973 province) and National Botanical Garden (one species), Dialectica Walsingham, 1897 of Iran (Tehran province) in 2017, (one species), Parornix Spuler, 1910 (two respectively, but Ph. roboris collected as species), Phyllocnistis Zeller, 1848 (one adult using light trap in Kordestan species), Phyllonorycter Hübner, 1822 (seven province. The larvae were reared in small species), and Polymitia Triberti, 1986 (two plastic containers at room temperature. species) (Zerny, 1940; Amsel, 1959; Esmaili, The adults were examined externally 1971; Deschka, 1979; Abai, 1984; Triberti, using a stereomicroscope with maximum 1985, 1986, 1990; Noreika, 1991; Puplesis et magnification 128×. The species were al., 1996; Modarres Awal, 1997; Dimić et al., identified based on their external 1997; Kuznetzov & Baryshnikova, 1998; appearance and their male genitalia Wieser et al., 2001; Abivardi, 2001).

Genitalia on the available literature, as far as 10 dissections were based on those described Phyllonorycter species are known from Iran by Clarke (1941) and Robinson (1976).

All of the During 2016-2017, symptoms of two examined specimens are deposited in the Phyllonorycter species, Ph. coryli (Nicelli, Hayk Mirzayans Insect Museum. 1851), and Ph. millierella (Staudinger, 1871) Results that occurred in Azarbaijan-e Sharghi and Tehran provinces, respectively were The adult examined specimens are briefly observed. The larvae of them were found characterized as follows: while feeding on Carpinus betulus L. Phyllonorycter coryli (Nicelli, 1851) (Betulaceae), and Celtis australis L.
