Megjegyzések:	The main goal of our research was to carry out a comprehensive study on the obligatorily myrmecophilous Maculinea alcon (Denis & Schiffermüller) whose taxonomy has remained highly debated despite the fact that Maculinea Van Eecke species are some of the most intensively studied insects in Europe. We aimed to elucidate the relationship between the different forms exploiting different ecological environments with specific regard to ♭Hirschke's rebeli' (M. rebeli (Hirschke)) from the high altitudes of the Styrian Alps which was studied in this respect for the first time. Molecular analyses including multiple gene sequences, microsatellites and allozymes completed with Wolbachia screening, together with geometric morphometry were applied on various sets of samples. Our results showed that ♭rebeli' from the type locality differed strongly from all other samples not only at the highly variable microsatellites, but also at standard genes and clearly represents a well?separated unit (potentially subspecies) within M. alcon. As all individuals were infected with a single Wolbachia strain, this is possibly an ancient infection with high maternal transmission rate. It also suggests that the separation of the topotypic populations was probably a relatively recent event which could have been promoted by genetic drift or specific conditions at high altitudes, and maintained by restricted gene flow. Both the genetic and the morphometric studies supported the proposition that the geographical origin of the populations has a higher effect on the structure of variation than the food plant use. Moreover, we detected more genetic lineages than could be defined by differential host plant usage.

Megjegyzések:	In this study we analysed for the first time the phylogenetic relationshipsamong the EuropeanLethrusspecies based on mitochondrial (COI, 16S) and nuclear(H3, wingless) markers. The phylogenetic inference based on these genes indicated thatthe EuropeanLethrusspecies form a monophyletic group with two main lineages. Oneof them is distributed in the central part of the Balkan Peninsula (North Macedonia,northwestern Greece and southwestern Bulgaria) and includes five species (L. perun,L. raymondi,L. strymonensis,L. halkidikiensisandL. elephas). Three species of theother clade (L. schaumii,L. aresandL. schneideri) occur in the eastern part of the BalkanPeninsula (southeastern Bulgaria and northeastern Greece) while its fourth member,L. apterus, could colonize much larger areas in central and eastern Europe. Despite itslarge geographic distribution,L. apterusproved to be a single species. By contrast, wefound strong intraspecific differentiation in bothL. schaumiiandL. halkidikiensisinspite of their restricted distribution. Surprisingly, two highly divergent mitogroups werealso detected within a singleL. schneideripopulation. As the microsatellite markersdid not show any differentiation between them, this finding is likely to be accountedfor by a unidirectional hybridization event. These findings highlight that phylogeneticstudies or species descriptions should not be based on mitochondrial markers alone. Ourstudy clearly demonstrates that allopatric speciation is the most important speciationmechanism in the European species of the genusLethrus, although we also hypothesizethat other well-known factors, such as hybridization or the glacial-interglacial dynamics,could significantly affect the speciation patterns of certain lineages.
