Four species of Paraproto have been recorded from the Australian coasts before the present study: P. condylata ( Haswell, 1885a) from Australia, P. gabrieli Stebbing, 1914 from Victoria, P. spinosa ( Haswell, 1885a) from Victoria and P. tasmaniensis Guerra-García and Takeuchi, 2004 . Of the four species of Paraproto , P. condylata and P. tasmaniensis have the body smooth, as in the present species. However, because of the lack of a modern description of P. condylata from Australia we hesitate to identify this small individual.

Paraproto condylata was first reported by Haswell (1885a) as Proto condylata Haswell, 1885a . He never noted the specific locality for this species in Australia unlike the record for P. spinosa ( Haswell, 1885a) that was recorded as “ only in one locality-Port Western, Victoria. ” Dr William A. Haswell served the University of Sydney around that period ( Morison 1983). If P. condylata was collected from Victoria or other states, there is a high possibility that he would have recorded the locality as for P. spinosa ( Haswell, 1885a) . Hence, P. condylata might have been collected from Sydney or adjacent areas along the coasts of New South Wales, Australia. Mayer (1903) also noted “ Paraproto condylata ? ” in the species list of “ Sydney (Port Jackson and Broken Bay) ”. The type material of P. condylata described by Haswell (1885a) is missing ( Springthorpe and Lowry 1994). McCain and Gray (1971) reported the occurrence of “ P. condylata ” from South Shetland Islands, Antarctica with several illustrations. Guerra-Garcia and Coleman (2001) redescribed and figured “ P. condylata ” based on the specimens collected by the Polarstern cruise ANT XIV/2 from South Shetland Islands. Their description and figures in general agree with the description by McCain and Gray (1971). De Broyer et al. (2004) identified Antarctic “ P. condylata ” as Paraproto sp. due to several morphological differences between the Australian and Antarctic specimens. Based on Antarctic “ P. condylata ” a new species is proposed ( Takeuchi, forthcoming 2015).
