Chromosomal formulae and genome sizes on phylogeny of Aphelinus species and several outgroups. Blue = 5 metacentric chromosomes; aqua = 1 metacentric and 4 acrocentric chromosomes; green = 2 metacentric and 2 acrocentric chromosomes; dark green = 1 metacentric and 3 acrocentric chromosomes; yellow = 2 metacentric, 1 subtelocentric, and 1 acrocentric chromosome; grey = unknown. Numbers after species names are genome sizes estimated from flow cytometry; values for Aphelinus abdominalis and E. formosa are from (Ardila-Garcia et al. 2010). The different colors for species of Aphelinus indicate membership in the four species complexes for which data are available.
