Dryinidae of the Eastern Palaearctic region (Hymenoptera: Chrysidoidea)

Abstract

An updated revision of Eastern Palaearctic Dryinidae is presented. Six subfamilies, 17 genera and 160 species are treated. Descriptions, geographic distribution, known hosts, natural enemies and type material of each species are presented, together with illustrations of the main morphological characters and keys to the subfamilies, genera and species. Complete lists of references concerning the Eastern Palaearctic Dryinidae and their hosts are given. The lectotype is designated for Anteon flaviscapus Jansson, 1950. A new combination is proposed for Mirodryinus olmii (Móczár, 1983), comb. nov. (from Radiimancus Móczár). The following new records are reported: Aphelopus prolatus Mita & Olmi, 2014 and Gonatopus formicicolus Richards, 1939 from Sweden; Aphelopus querceus Olmi, 1984, Aphelopus serratus Richards, 1939 and Anteon reticulatum Kieffer, 1905 from Bulgaria; Gonatopus nigricans (R. Perkins, 1905) from Solomon Islands; Haplogonatopus oratorius (Westwood, 1833) from Germany and Sweden.

A new species of the genus Gonatopus Ljungh from the USA (Hymenoptera, Dryinidae)

“…The term “metapectal-propodeal complex” is here used in the sense of Kawada et al (2015). It corresponds to the term “propodeum” sensu Olmi (1984, 1994), Xu et al (2013), Olmi and Virla (2014), and Olmi and Xu (2015).…”

“…However, the biology of this group of small wasps is still poorly known (Guglielmino et al 2006, 2008, 2015). Gonatopus Ljungh, 1810 is a genus that is present in all zoogeographical regions (Olmi 1984; Guglielmino and Virla 1998; Guglielmino and Bückle 2003, 2010; Xu et al 2013; Olmi and Virla 2014; Olmi and Xu 2015). In total 441 species have been described from all continents (Guglielmino and Olmi 2014; Olmi and Xu 2015) and the genus was revised at world level by Olmi (1984, 1991), and more recently in the Oriental, Neotropical and Eastern Palaearctic regions by Xu et al (2013), Olmi and Virla (2014) and Olmi and Xu (2015),…”

First report of Cheiloneurus exitiosus (Perkins, 1906) and Helegonatopus dimorphus (Hoffer, 1954) (Hymenoptera: Encyrtidae) from Japan, with remarks on their abundance in rice paddies

“…Materials are deposited in the Entomological Laboratory, Faculty of Agriculture, Kyushu University (ELKU). Distribution and host records were obtained from Guerrieri and Viggiani (2005), Xu et al (2013) and Olmi and Xu (2015).…”

“…Some encyrtid wasps are known as parasitoids of Dryinidae (Guerrieri and Viggiani 2005, Olmi and Xu 2015 and Xu et al 2013). There are two genera of encyrtids reported as parasitoids of Dryinidae, namely, Cheiloneurus Westwood and Helegonatopus Perkins.…”

A new species of the genus Anteon Jurine (Hymenoptera, Dryinidae) from Laos

“…Anteon Jurine, 1807 is a genus that is present in all zoogeographical regions (Olmi 1984; Xu et al 2013; Olmi and Virla 2014; Olmi and Xu 2015). In total 423 species have been described from all continents (Olmi and Xu 2015) and the genus was revised at the world level by Olmi (1984, 1991) and more recently in the Oriental, Neotropical and Eastern Palaearctic regions by Xu et al (2013), Olmi and Virla (2014) and Olmi and Xu (2015) respectively.…”
