Polyommatus ripartii is a biogeographically and taxonomically poorly understood species of butterfly with a
scattered distribution in Europe. Recently, it has been shown that this species includes several European endemic
and localized taxa (galloi, exuberans, agenjoi) that were previously considered species and even protected, a result
that poses further questions about the processes that led to its current distribution. We analysed mitochondrial
DNA and the morphology of P. ripartii specimens to study the phylogeography of European populations. Three
genetically differentiated but apparently synmorphic lineages occur in Europe that could be considered evolutionarily
significant units for conservation. Their strongly fragmented and counterintuitive distribution seems to be the
result of multiple range expansions and contractions along Pleistocene climatic oscillations. Remarkably, based on
the 79 specimens studied, these genetic lineages do not seem to extensively coexist in the distributional mosaic,
a phenomenon most evident in the Iberian Peninsula. One of the important gaps in the European distribution of
P. ripartii is reduced by the discovery of new Croatian populations, which also facilitate a better understanding of
the biogeography of the species.

Approximately 50 taxa of butterflies in Western Europe have been described as new species or elevated to the level
of species during the last 40 years. Many, especially those belonging to the genus Agrodiaetus, have unusually
localized, ‘dot-like’ distributional ranges. In the present study, we use a combination of chromosomal and molecular
markers to re-evaluate the species status of Agrodiaetus distributed west of the 17th meridian. The results
obtained do not support the current designations of Agrodiaetus galloi, Agrodiaetus exuberans, and Agrodiaetus
agenjoi as endemic species with highly restricted distribution ranges, but indicate that these taxa are more likely
to be local populations of a widely distributed species, Agrodiaetus ripartii. Agrodiaetus violetae is shown to be a
polytypic species consisting of at least two subspecies, including Agrodiaetus violetae subbaeticus comb. nov. and
Agrodiaetus violetae violetae. Agrodiaetus violetae is genetically (but not chromosomally) distinct from Agrodiaetus
fabressei and has a wider distribution in southern Spain than previously believed. Agrodiaetus humedasae from
northern Italy is supported as a highly localized species that is distinct from its nearest relatives. We propose a
revision of the species lists for Agrodiaetus taking these new data into account. The results reported in the present
study are relevant to animal conservation efforts in Europe because of their implications for IUCN Red List
priorities.
