“…The coldest periods drove sand flies and their pathogens to the southern Mediterranean coastlines 45 . Due to the climate-ameliorating effect of the Mediterranean Sea, some sand fly populations also survived on the Mediterranean islands, which were colonized during the Messinian salinity crisis in the latest Miocene epoch by sand flies 29 , 39 , 41 , 48 . For example, genetic evidence suggests that some species, such as Ph.…”

Phlebotomine sand flies (Diptera: Phlebotominae) are the principal vectors of Leishmania spp. (Kinetoplastida: Trypanosomatidae). In Central Europe, Phlebotomus mascittii is the predominant species, but largely understudied. To better understand factors driving its current distribution, we infer patterns of genetic diversity by testing for signals of population expansion based on two mitochondrial genes and model current and past climate and habitat suitability for seven post-glacial maximum periods, taking 19 climatic variables into account. Consequently, we elucidate their connections by environmental-geographical network analysis. Most analyzed populations share a main haplotype tracing back to a single glacial maximum refuge area on the Mediterranean coasts of South France, which is supported by network analysis. The rapid range expansion of Ph. mascittii likely started in the early mid-Holocene epoch until today and its spread possibly followed two routes. The first one was through northern France to Germany and then Belgium, and the second across the Ligurian coast through present-day Slovenia to Austria, toward the northern Balkans. Here we present a combined approach to reveal glacial refugia and post-glacial spread of Ph. mascittii and observed discrepancies between the modelled and the current known distribution might reveal yet overlooked populations and potential further spread.

The Oligocene and Miocene tectonic and biogeographical alterations of the peri-Mediterranean area could strongly impact the speciation processes and migrations of Mediterranean sandfly species. To understand the possible former role of this palaeobiogeographic factor on ancestral sandfly species, the potential suitability values of five Larroussius, two Paraphlebotomus and one Phlebotomus species were modelled from the Rupelian to the Tortonian stage in the Central Paratethys. The bioclimatic extrema of this sandfly species and the Coexistence Approach-based palaeoclimatic reconstructions made the basis of hypothesis testing. In the case of the Tortonian stage, a georeferenced climatic model was created. The models indicate that the suitability values could notably vary by species and periods. The monsoon-influenced humid subtropical climate of the Oligocene epoch could be less suitable for the ancestors of Mediterranean sandfly taxa than the later, drier humid subtropical climates-characterised Miocene stages. The Central Paratethys area could be less suitable for ancestors of the extant Paraphlebotomus, and Phlebotomus in the Miocene epoch compared to Larroussius species. It may indicate that the Central Paratethys formed a barrier against the east-to-west migration of the ancestors of Phlebotomus and Paraphlebotomus species. In contrast, Larroussius species could prefer the Miocene climate of the Central Paratethys. In the Tortonian stage, mainly the coastal areas of the sea could be colonised by sandflies. These results indicate that the coasts of the Central Paratethys should be not only considered as a potential former migration route but could be a part of the speciation area of Larroussius sandflies.

The distribution of the Mediterranean Transphlebotomus species shows a marked zoogeographical dichotomy in the sense that Phlebotomus mascittii has a wide range in Europe, and the other species are restricted to the East Mediterranean region. The study aimed to investigate how the Neogene to late Quaternary climatic-geographical alterations could influence the split of the sandfly subgenus Transphlebotomus and the speciation of Phlebotomus mascitti. For this purpose, the climatic suitability patterns of the species were modelled for seven Neogene and Quaternary periods and the divergence times of Transphlebotomus clades were estimated. The model results suggest that the common ancestor of the extant Mediterranean-European Transphlebotomus species could be adapted to the Late Miocene climate of Western and Central Europe. Phylogenetic results suggest that the speciation of Ph. mascittii started in the Tortonian period, plausibly related to the rise of the Dinaric land bridge. The Central and Eastern Paratethys Seas could have played an important role in the split of the ancestral Phlebotomus mascittii populations and other Transphlebotomus populations. These other species can be the descendants of ancient Transphlebotomus populations adapted to the hotter and drier climate of the areas south of the Central and Eastern Paratethys. Their divergence could be strongly linked to the formation of the Aegean trench and, later, the Messinian salinity crisis. The Pliocene climatic fluctuations could result in habitat loss of Transphlebotomus populations in Europe which was particularly significant during glacial maxima such as the Last Glacial Maximum.
