FIGURE 1 in A proposed order-level classification in Oligochaeta (Annelida, Clitellata)

FIGURE 1. Phylogenetic relationships of families of Oligochaeta (=oligochaetous Clitellata), schematized after Erséus et al. (2020), and corresponding proposals of order-level taxa, printed in bold regular. Taxa with question mark were not investigated in Erséus et al. (2020) for lack of DNA data. Broken line boxes and words in capital letters: class level, continuous line boxes and words in bold italics: subclass level. The polyphyletic Haplotaxidae appears three times; the name without brackets represents the position of the type species, Haplotaxis gordioides (Hartmann in Oken, 1819).
