FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK Volume 68 2007 pp. 143-146. On the distribution of Hadena bicruris (Hufnagel, 1766) and Hadena capsincola ([Denis et Schiffermüller], 1775) in Hungary (Lepidoptera: Noctuidae) S. SlMONYI H-1031 Budapest, Sóvári u. 30. E-mail: simonyis@budapest.hu Abstract - Hadena capsincola and Hadena bicruris specimens were examined from several localities of Hungary. The morphological data suggest the presence of a hybridisation zone between the two closely related species in Hungary. With 8 figures. Key words - Hadena capsincola, H. bicruris, distribution, Hungary. INTRODUCTION There are contradicting records about the existence of Hadena bicruris (HUFNAGEL, 1766) and Hadena capsincola ([DENIS et SCHIFFERMÜLLER], 1775) in Hungary. In the monograph of the genus Hadena SCHRANK, 1802, HACKER (1996) interpreted//, capsincola as a species distinct from//, bicruris, providing the re-description of the taxon and all associated former references from Hungary with H. capsincola. The checklist of the Hungarian Macrolepidoptera (VARGA etal. 2004) mentions only//, bicruris from the two related species. Most recently, the guide book on the Hungarian Cuculliinae, Hadeninae and Noctuinae (RONKAY & RONKAY 2006) accepted the opinion of HACKER 1996, but supposing also the possible occurrence of H. bicruris, waiting for explicite evidence. The main questions, according to the authors, are the possible presence of H. bicruris within the Carpathian basin and the possible existence of a zone of hybridisation between the two species in Hungary.
