1998e. Two new semi-aquatic species of Diplotrema (Oligochaeta:
Megascolecidae: Acanthodrilinae), with a re-description of the type species.
of the Queensland Museum 42, 487-493.
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.
