New records of ichneumon wasps (Hymenoptera, Ichneumonidae) from Malta with an updated checklistThomas CASSAR1 & David MIFSUD2ABSTRACT. Ten new records of ichneumon wasps are reported for the first time from Malta. A checklist of all 56 species of Ichneumonidae so far recorded from Malta is also included.KEY WORDS. Mediterranean, ichneumonids.INTRODUCTION  Mifsud (2012) provided a revised check-list of the Maltese ichneumonid fauna, listing a total of 29 species. Since then several new records of ichneumon wasps from the Maltese Islands were published (Cassar, 2013; Vas et al., 2015; Vas, 2016; Mifsud et al., 2019). Recently, Dr Gavin Broad of the Natural History Museum in London examined unidentified material collected from the Maltese Islands and 10 new records to the Maltese fauna were found and are recorded here under. Material is deposited in the private collection of the senior author. An updated check list of all 56 species of Ichneumonidae so far recorded from the Maltese Islands is provided (Appendix 1) in the present work.ANNOTATED SPECIES LISTCryptus subspinosus (Smits van Burgst, 1913)(Cryptinae)Material examined: Malta, Dingli, 17.iii.2018, 1 ♀, leg. T. Cassar.Notes: Cryptus subspinosus has a largely circum-Mediterranean distribution though records exist from western Asia (Iran). Cryptus species are predominantly associated with Lepidoptera.Ctenichneumon ? divisorius (Gravenhorst, 1820)(Ichneumoninae)Material examined: Malta, Manikata, 14.ii.2016, 1 ♂, leg. T. CassarNotes: Ctenichneumon divisorius has a Palearctic distribution. It is a larval endoparasitoid of several Noctuidae (ThoMpson, 1957).BULLETIN OF THE ENTOMOLOGICAL SOCIETY OF MALTA (2019) Vol. 10 :  97–101DOI: 10.17387/BULLENTSOCMALTA.2019.101 Speranza, Triq il-Qubbajt, Żebbug, ZBG 1182, Malta.

E-mail: david.a.mifsud@um.edu.mtLinycus exhortator (Fabricius, 1787)(Ichneumoninae)Material examined: Malta, Dingli, 17.iii.2018, 1 ♀, leg. T. Cassar.Notes: Linycus exhortator has a widespread Holarctic distribution. It is an endoparasitoid of various Geometridae larvae.Metopius ? laticinctellus (Hortsmann & Yu, 1999)(Metopiinae) Material examined: Malta, Mtaћleb, 23.ii.2014, 1 ♀, leg. T. Cassar.Notes: The genus Metopius accommodates over 130 species globally, with around 70 of these occurring in the Palaearctic. They are larval endoparasitoids of several Lepidoptera such as Sphingidae, Geometridae, Lasiocampidae, Noctuidae, Erebidae and Papilionidae (TolkaniTz, 2015).Netelia lineolata (Costa, 1883)(Tryphoninae)Material examined: Malta, Żebbuġ, 21.iii.2014, 1 ♂, leg. T. Cassar.Notes: Netelia lineolata has a western Palaearctic distribution but can be found eastwards as far as Iran. It was recorded as an ectoparasitoid of Anacampsis timidella (Wocke, 1887) (Lepidoptera, Gelechiidae) (auberT et al., 1984).Campoplex sp. (Campopleginae)Material examined: Maltese Islands. Comino, Il-Ħażina, 13.viii.2002, 1 ♀, leg. D. Mifsud.Notes: The genus Campoplex currently accommodates over 200 described species which have a worldwide distribution. Species are associated mainly with various micro-lepidopterans, such as a number of Gelechioidean families and Tortricidae.Heterischnus sp. (Ichneumoninae)Material examined: Malta, Marfa, 22.viii.2014, 1 ♂, leg. T. Cassar.Notes: This genus is widely distributed in the Palaearctic, Nearctic and Afrotropical regions. Heterischnus accommodates 28 described species which are largely endoparasitoids of various Pterophoridae.                                                                                                        T. CASSAR & D. MIFSUD98Phygadeuon sp. (Cryptinae)Material examined: Malta, Mellieћa, 24.xii.2017, 1 ♀, leg. T. Cassar.Notes: Phygadeuon is a species-rich genus (over 200 described species) with a worldwide distribution. Species are usually endoparasitoids of Diptera. Trathala sp. (Cremastinae)Material examined: Malta, Marfa, 20.vii.2014, 1 ♂, leg. T. Cassar.Notes: The genus Trathala is represented by about 100 described species worldwide, three of which have a Palaearctic distribution (Choi et al., 2014). Species are predominantly larval endoparasitoids of micro-lepidopterans.Zoophthorus sp. (Cryptinae)Material examined: Malta, Żebbuġ, 9.iv.2015, 1 ♀, leg. T. Cassar.Notes: The genus Zoophthorus accommodates 27 described species which have a Holarctic and Neotropical distribution. They are endoparasitoids associated largely with micro-lepidopterans (such as various Gelechiidae, Gracillariidae and Coleophoridae).ACKNOWLEGMENTS  We would like to thank Dr Gavin Broad for all his help in identifying material included in the paper and for correcting this work.REFERENCESauberT, J. f., halperin, J., & GerlinG, d.
