Distributions of Higher Nematinae species on different plant genera. Proportions are shown separately for the tribe Pristiphorini and for its sister clade composed of the tribes Mesoneurini and Nematini (see Figs. 3 and 4). Host data and estimates of species numbers are from Lacourt's  checklist of Western Palearctic sawflies, plant families are denoted by separate font colors (see legend). Numbers in parentheses after tribe names are in the order: total number of species/number of Western Palearctic species/number of Western Palearctic species with known hosts.
