New Records and Updated Checklist of the Pentatomoidea (Hemiptera: Heteroptera) of Greece

Simple Summary An updated species checklist for all the Pentatomoidea species for Greece is provided. Eight species are recorded from Greece for the first time. The checklist is supported with distributional data notes for all the Pentatomoidea species of Greece. Abstract Eight species of the superfamily Pentatomoidea are recorded from Greece for the first time: Aelia germari Küster 1852, Eurygaster hottentotta (Fabricius 1775), Eysarcoris aeneus (Scopoli 1763), Neottiglossa lineolata (Herrich-Schaeffer 1830), Neottiglossa pusilla (Gallen 1789), Picromerus bidens (Linnaeus 1758), Podops (Podops) inunctus (Fabricius 1775) and Tarisa pallescens (Jakovlev 1871). A complete updated species checklist with distributional data notes for all the new species for Greece are provided.


Introduction
The superfamily Pentatomoidea constitutes one of the most important insect groups of the suborder Heteroptera. It includes 1080 genera and 5907 species belonging to 16 families of which the Cydnidae, Pentatomidae, Scutelleridae and Tessaratomidae are the most important; 94% of the species belong to these four families [1][2][3]. Pentatomidae is the fourth most numerous family within Heteroptera with more than 4700 species, commonly known as stink bugs [4]. It includes predominantly herbivorous species, some of them having high economic importance, such as the brown marmorated stink bug Halyomorpha halys (Stål) and the southern green stink bug Nezara viridula (L.).
Halyomorpha halys is a polyphagous stink bug native to China, Korea, Japan and Taiwan [5]. It was introduced into the United States in the mid-1990s, resulting in losses of apples, peaches, tomatoes and other important crops [6]. Recently, it has been detected in Europe for the first time in Switzerland in 2007, damaging stone fruits and legume pods [7]. Until recently, it has been recorded in many European countries including Greece [8], and it is considered a potential threat to agricultural productivity in all these regions [9,10] since it has a broad host range and is capable to disperse long-distance by flight [11].
There have been sporadic references on specific species of Pentatomoidea in Greece [8,, and two overall studies, one in 1980 [44] and the other in 2019, which updated the previous one and included all new species [45]. Given the worldwide problem of the brown marmorated stink bug pest status [6] and its presence in Greece [8], understanding this family in Greece may assist in distinguishing this pest species from native ones, and Results of this study showed that 92 species were found in 52 genera, belonging in 10 subfamilies, within 5 families of Pentatomoidea: Acanthosomatidae (Acanthosomatinae), Cydnidae (Cydninae, Sehirinae), Pentatomidae (Asopinae, Pentatominae, Podopinae), Plataspidae (Plataspinae) and Scutelleridae (Eurygastrinae, Odontoscelinae, Odontotarsinae). Eight of these species are new records for Greece: 6 species of the subfamily Pentatominae (Pentatomidae) and 2 species of Podopinae (Pentatomidae). The updated checklist with the new records is referred below in the text and in Table 1.

Discussion
In Greece, until the present work, very few studies have been conducted on the Pentatomoidea fauna, in which 150 Pentatomoidea species are referred. Except two overall studies performed by Drosopoulos [43] and Ramsey [44], in 1980 and 2019, respectively, only sporadic references are made by numerous researchers, considering the Greek fauna as part of a wider Balkans. In the present study, 8 species are recorded in Greece for the first time, raising the number of the Greek fauna to 158 species. It has to be mentioned that the new records refer to specimens that were collected during [1982][1983] and placed in the historic collection of Sakis Drosopoulos. Our study provides one step toward enriched knowledge of the Pentatomoidea fauna of Greece, which will hopefully trigger more comprehensive taxonomic study of the entire superfamily.
