Abstract

This study provides data on the first known established populations of two allochthonous species in Romania, Mustha spinosula and Perillus bioculatus. Overwintering, host plants and distribution of these two pentatomids (Heteroptera: Pentatomidae) are briefly discussed. We also provide information on color variation in nymphs of Mustha spinosula and report a new host plant for this species.

Highlights

  • The true bugs are a highly diverse group of insects with over 40000 species worldwide (Schuh and Slater 1995) from which only around 9400 species are occurring in the Palaearctic region (Aukema et al 2013)

  • This study provides data on the first known established populations of two allochthonous species in Romania, Mustha spinosula and Perillus bioculatus

  • We report for the first time well-established populations of two taxa: Mustha spinosula (Lefebvre, 1831) a range expanding species and the alien species Perillus bioculatus (Fabricius, 1775), both from the family Pentatomidae

Summary

Introduction

The true bugs are a highly diverse group of insects with over 40000 species worldwide (Schuh and Slater 1995) from which only around 9400 species are occurring in the Palaearctic region (Aukema et al 2013). Six alien true bugs species were recorded so far in Romania, with three taxa reported in the last 10 years (Grozea et al 2012; Macavei et al 2015; Don et al 2016). This is obviously a low number considering that Romania represents an important economic route point for both terrestrial and marine ecosystems. We report for the first time well-established populations of two taxa: Mustha spinosula (Lefebvre, 1831) a range expanding species and the alien species Perillus bioculatus (Fabricius, 1775), both from the family Pentatomidae
