Taxonomic Notes
Salata & Borowiec, L., 2018: Karavaiev (1912), in the description of L. splendens, mentioned the following features to distinguish it from L. nigra: more smooth and slender body surface, head shape and size of propodeal spines. Examination of type specimens and study on samples collected from different Cretan sites manifested wide variability within features mentioned by Karavaiev. Also, we didn’t find any strong features that support an existence of two different species. Therefore we consider L. splendens as a junior synonym of L. nigra.
