<i>Cynaeus opacus</i> Champion, a new tenebrionid beetle in Finland (Coleoptera, Tenebrionidae)

Abstract

From1989 on Cynaeus opacus Champion has been found in waste heaps and similar localities in southern Finland together with other synanthropic beetles. Cynaeus is an American genus spreading with man; another species, C. angustus (LeConte), has recently been recorded from Sweden.

First record of the invasive alien species Cynaeus angustus (LeConte, 1851) (Coleoptera, Tenebrionidae) in Bulgaria

“…Since the early 1990s, the species has been frequently reported in many European countries (Fig. 5): Finland (Mannerkoski & Ferrer, 1992;Ferrer, 1995;Ferrer & Andersson, 2002b;Silfverberg, 2010;GBIF, 2022), Sweden including the island of Gotland (Ferrer, 1995;Lundberg, 1996;Ferrer & Andersson, 2002b;Denux & Zagatti, 2010;Silfverberg, 2010;Wikars, 2014;GBIF, 2022), Germany (Reibnitz & Schawaller, 2006;Kopetz et al, 2008;Köhler & Köhler, 2009;Eichler & Pütz, 2017;Pütz, 2020;GBIF, 2022), France (Callot & Matt, 2006Soldati, 2007;Soldati & Godiant, 2013), Estonia (Roosileht, 2015;GBIF, 2022), Ukraine (Drogvalenko & Konovalov, 2016;Kovalenko et al, 2016;UkrBIN, 2022), European Russia (Kovalenko et al, 2016), Czech Republic (Mantič & Vávra, 2017;Novák et al, 2019;Hron, 2020;Novák & Ryšánek, 2020), Poland (Ruta et al, 2017;Kadej et al, 2019;Królik, 2019;Bunalski et al, 2020), Latvia (Telnov et al, 2020), Hungary (Merkl & Szalóki, 2020) and Romania (Pintilioaie & Teodorescu, 2021). The beetle was also reported in the following Asian countries: Thailand (Sukprakarn & Tauthong, 1981), Bangladesh…”

Cynaeus angustus (Coleoptera: Tenebrionidae), a new alien beetle in Romania

“…However, the population probably was not the source of spreading for the species in Europe, since no other observations of C. angustus are reported from Ireland. The species was subsequently recorded in Finland (in 1989) (Mannerkoski and Ferrer 1992) and Sweden (in 1993) (Lundberg 1996), misidentified as Cynaeus depressus Andersson 2002a, 2002b). It was then recorded in Germany (1996) (Reibnitz and Schawaller 2006), France (1997) (Soldati and Godinat 2013), Ukraine (2012) (Kovalenko et al 2016), Czech Republic (2014) (Mantič and Vávra 2017), Poland (2015) (Ruta et al 2017), European Russia (2016) (Kovalenko et al 2016) and Latvia (2019) (Telnov et al 2020).…”

“…In its native habitat, Cynaeus angustus feeds on decaying plant remains (Agave sp., Yucca sp., and other semi-succulent species) (Dunkel et al 1982), but in new occupied areas it was found frequently to feed on crop residues and stored products (especially corn, but also wheat, soybeans, oats, dried fruits, etc.) (Dunkel et al 1982;Mannerkoski and Ferrer 1992;Lundberg 1996;Reibnitz and Schawaller 2006;Soldati and Godinat 2013), making it a species of minor economic importance, especially in USA (Dunkel et al 1982). In Europe C. angustus can be also found in nature, under the bark of deciduous (Ulmus sp.…”

“…(Wikars 2014)). It is also attracted to light (Dunkel et al 1982;Mannerkoski and Ferrer 1992;Reibnitz and Schawaller 2006;Kovalenko et al 2016;Eichler and Pütz 2017;Novák et al 2019;Novák and Ryšanek 2020;Telnov et al 2020). Cynaeus depressus was recorded so far only in Sweden (Andersson and Ferrer 1989), where it was originally misidentified as Cynaeus angustus Andersson 2002a, 2002b).…”
