The types and arrangement of scales and sensilla on penial lobes are summarized for West Palaearctic species groups with some preliminary changes in species grouping proposed. An annotated checklist of the Balkanian species is given and the known distribution of endemic taxa are depicted onmaps. Isoperla oxylepis balcanica and I. vevcianensis are new for the fauna of Albania, while I. bosnica and! grammatica (Poda, 1761) are new for Montenegro and Greece, respectively. Additional significant new country records are provided for Amphinemuratriangularis (Ris, 1902), A. quadrangularis Zwick, 1978, Nemoura caligula Zwick, 1978 and Leuctra jahorinensis Kacanski, 1972.
