Remarks.

As a result of the treatment during the barcoding process, all vouchered individuals except one male and two females were partly or completely destroyed. With regards to the shape of the eye bridge and gnathosoma, the specimens examined in our study matches the description of E.tantilla given by K. Viets (1930) for material from Spain. The sequenced specimens from Portugal form a unique BIN (BOLD:AFP3591), with the nearest neighboring BIN being BOLD:ACS1138, which includes three public sequences of specimens from Norway assigned to E.rimosa Piersig, 1899, and three unpublished sequences of specimens from the Netherlands, two of them assigned to E.extendens and one assigned to E.setosa Koenike, 1897. The p-distance between these two BINs was estimated at 14.83%.
