Molecular and Morphological Delineation of Lamprochernes Mites

Lamprochernes individuals were collected by compost sifting and extraction and from on or under tree bark across Europe (Table S1, Figure 1). The specimens were preliminarily determined, following the literature [56 (link)]. Distribution maps were created in SimpleMappr [71 ] and edited with Adobe Illustrator. Geographic distances among sample localities were obtained in Geographic Distance Matrix Generator [72 ]. To delimit Lamprochernes species, we first implemented a molecular data-based species discovery step, which was followed by a species validation step combining multispecies coalescent analyses (molecular data), morphometric analyses (morphology data) and cytogenetic analyses (karyotype data).
