Notes on species of Actaecia Dana

A Tasmanian species, which was described in an earlier paper but wrongly assigned there to Actaecia euchroa Dana, is named as Actaecia thomsoni, n. sp. Differences between A. euchroa and A. thomsoni are listed. The presence of pseudotracheae in the pleopoda of A. thornsoni, and of A. pallida Nicholls and Barnes, is confirmed.
Variations in the colour of specimens of A. euchroa from New Zealand are noted.
