Remarks. We remarked under genus Plesiocolochirus (above) that the phylogenetic tree (Figure 1) supports two discrete and geographically separate Plesiocolochirus species clades from NE Australia (Plesiocolochirus species 2) and NW Australia (Plesiocolochirus species 1). Either clade might be representative of Plesiocolochirus australis or Plesiocolochirus minutus. Identification of the Camden species awaits morphological examination of the relevant types and additional phylogenetic data
