  1. 1Epigeic: live and feed on the soil surface; Endogeic: live and feed within the soil; Anecic: live within the soil and dig vertical or semi-vertical burrows to feed on the soil surface (after [45],[46]). Endo-anecic worms have characteristics of anecic (anterodorsal pigmentation, flattened rear end) and endogeic worms (horizontal burrowing).
  2. 2Average biometric data for adults (g.f.w.indicates grams of fresh weight in 4% formalin, gut contents included).
  3. 3NC: not classified.
