Diagnoza Wide and asymmetric platform of P1 element with densely tuberculated dorsal part separated from smooth ventral areas by a transverse row of larger tubercles. Porównanie Early populations of L. styriacus show great variability in their platform outline, some specimens being narrower even than in the ancestral L. granulosus. The transition apparently took a significant time span, the zonal boundary is thus hardly clear-cut. It is possible that some populations from Ostrówka co-occurring with P. trachytera actually represent L. granulosus, not L. styriacus as suggested by their variable morphology Autekologia Występowanie geograficzne Jabłonna, Ostrówka, Kowala, and Miedzianka.
