He suggested that it was possible that the small Seychelles specimens could be juveniles of the Australian species. L. australiensis was also reported from Indonesia (cf. Van Soest & De Voogd 2015, p. 95) and from South Africa ( Borojević 1967, p. 221 ). Borojević (1967) and Borojević & Boury-Esnault (1987b) supported Dendy’s view and synonymized L. proteus with L. australiensis , but eventually Borojević et al. (2000) reassigned L. proteus to Paraleucilla proteus as a separate valid species. Above, the species is compared with Paraleucilla erpenbecki sp.nov. , showing that the differences with that species are considerable.
