165. Dyne, G.R. and Jamieson, B.G.M. 1998e. Two new semi-aquatic species of Diplotrema (Oligochaeta: Megascolecidae: Acanthodrilinae), with a re-description of the type species. Memoirs of the Queensland Museum 42, 487-493.
Two new species of the genus Diplotrema sharing a suite of morphological
  characters and a semi-aquatic mode of life are described. Together with
  the previously described D. tyagarah, they are placed in a species-group
  the nominate species of which is the generic type-species, D. fragilis.
  The latter taxon, of pivotal importance in early phylogenetic schemes
  owing to an erroneous determination of the condition of the male pores, is
  redescribed from the syntypes.
