Remarks 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). : Published as part of Takeuchi, Ichiro & Lowry, James K., 2015, A taxonomic study on the Phtisicidae (Crustacea: Amphipoda) of New South Wales, Australia, pp. 603-648 in Journal of Natural History 50 on pages 640-641, DOI: 10.1080/00222933.2015.1079338, http://zenodo.org/record/3985737 : {"references": ["Haswell WA. 1885 a.
