Palaeoclimatic models - predicted changes in the potential Neogene distribution patterns of Phlebotomus similis and Phlebotomus sergenti (Insecta: Diptera: Psychodidae)

Abstract Former studies proposed that the speciation of subgenus Paraphlebotomus happened in Neogene Epoch circum-Mediterranean region due to geographical segregation effect former Paratethys Sea. It was aimed study whether modelled ranges Phlebotomus sergenti and similis support or contradict this barrier role sandfly. For purpose, potential were based on present climatic requirements taxa. The Miocene models do not circum-Paratethyan migration ancestor . In general, shows a low affinity North Paratethyan shorelines during entire epoch. only exceptions are Tortonian early Messinian periods when conditions could be suitable for shorelines. found neither late Miocene, Pliocene nor mid-Pleistocene period distributions notable differences suitability values Balkans Middle East. is most plausible divergence its relatives related tectonic subsidence Hellene Orogenic Belt specialised Balkan Peninsula present-day Pontic area middle-late desiccations Mediterranean Basin Zanclean re-flood caused migration, but sister
