Acta Musei Moraviae, Scientiae biologicae (Brno) 94: 27–42. – The past and recent occurrence of Tropidothorax leucopterus (Goeze, 1778) (Lygaeidae: Lygaeinae) in the Czech Republic and Slovakia is analysed, and the biology and ecology of the species are reviewed. It is recorded for the first time from Bohemia, which testifies to its current northward spread in Central Europe. Keywords. Heteroptera, Lygaeidae, Tropidothorax leucopterus, Bohemia, Moravia, Czech Republic, Slovakia, Greece, biology, ecology, range expansion Introduction Tropidothorax leucopterus (Goeze, 1778) is a conspicuous aposematically-coloured (red-and-black) true bug (Figs 3, 4) trophically bound to plants of the family Apocynaceae s. lat. (including Asclepiadaceae) (PÉRICART 1999, WACHMANN et al. 2007; ENDRESS & BRUYNS 2000). It is widely distributed in southern, Central and Eastern Europe (Albania, Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, the Czech Republic, France, Germany, Greece, Hungary, Italy, Liechtenstein, Macedonia, Moldavia, Poland, Portugal, Romania, southern and central European Russia, Serbia, Slovakia, Slovenia, Spain, Switzerland, Ukraine), North Africa (Algeria, Egypt), and Asia from the Near East to northern India (Azerbaijan, Afghanistan, Armenia, Georgia, India, Iran, Iraq, Kazakhstan, Kyrgyzstan, Tadzhikistan, Turkey, Turkmenistan, and Uzbekistan) (PÉRICART 2001; PROTIÆ 2001, KONDOROSY et al. 2006). HAMID & MEHER 27 P. K MENT et al. (1976) expected this species from Pakistan, but they were unable to find a reliable record from this country. The occurrence in Indonesia (PUTSHKOV 1969, without exact locality) is most probably based on misidentification. In the Czech Republic the species was previously known only from southern Moravia (SPITZNER 1892, KMENT et al. 2003). In this paper we review all the records from the Czech Republic and Slovakia and discuss the possible current spread of the species in central Europe. Review of the records The records are arranged chronologically. Codes for the Central European mapping grid (EHRENDORFER & HAMANN 1965) follow PRUNER & MÍKA (1996) and NOVÁK (1989).
