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
