Notes. Meristic and morphological data do not separate purported H. procerus from H. whitei (Appendix O), nor do genetics. Four specimens from Moreton Bay (the type locality for H. procerus) included three haplotypes, each of which was identical to a haplotype from Sydney Harbour (type locality for H. whitei) (H. Hamilton, in litt. to SL and RP, 13 Feb 2015).
