Morphotypes and genetic lineages described for E. manto. 1. Valve shape of typical representatives of the three morphotypes after Cupedo (1997). A manto type, Col de la Croix (CH-VD), prep.nr. 1503. B bubastis type, Col de la Madeleine (F-73), prep.nr. 1113. C vogesiaca type, Rainkopf (F-68), prep.nr. 1705. Scale bar: 1 mm. 2. Neighbour-joining phenogram by Schmitt et al. (2014), based on Nei’s genetic distances (Nei 1972). Numbers represent individual samples. Bootstrap values >50% (1000 iterations) are given at the nodes.
