Molecular analysis

DNA sequencing resulted in a BIN-concordant DNA barcode fragments for 140 out of 141 specimens, representing 16 species, which were included in the analysis. 118 DNA barcodes of 658 bp were supplemented by 17 shorter sequences of 610–646 bp and 5 sequences of 385–408 bp. For five European species, no barcodes are currently available: E. farreni, E. wockeellus, E. lusitanica, E. theimeri, and E. pumila, but all these species differ from the newly described taxon in external morphology and genitalia.

A barcode gap analysis supplied by BOLD tools resulted in a normalized mean within-species divergence of 0.75% (SE 0.07). In contrast, the mean interspecific divergence was 9.18% (SE 0.19), ranging from minimum 5.21% to maximum 12.85% uncorrected distance to the Nearest Neighbor (Fig. 1, Tab. 1). All species grouped in unique BINs and only two species split in two or three BINs (Ratnasingham & Hebert 2013). However, it should be noted in this context that the number of sequences is low for several species. The three BINs of E. pontificella somewhat reflect a geographic structure, which may indicate cryptic allopatric diversity.
