Genus Hippocampus Rafinesque, 1810

 

Introduction

There is considerable disagreement in the literature over the appropriate names and number of species found in Australia. Kuiter (2001) revised Australian species in the genus, recognising 24 species in the region. Subsequently 3 additional species have been described and additional species found with 29 or 30 described species known from Australia (Kuiter 2009). Lourie et al. (2016) reduced the number to 20 species. In many cases genetic work has not been published on Australian species. Lourie et al. (2016) stressed that the species were their concept as they understood the species and accepted at least a 2% difference in DNA sequences to recognise species differences. Often they did not address the characters used by Kuiter (2001) and did not present detailed statistical analyses of their data. Consequently we have not been able to confirm their synonymies in all cases. We accept those synonymies where there is genetic evidence for synonymy, where Australian studies support the syonymies, or where the complexity prevents adequate separation of species at the present time. However, we retain species with apparently geographically isolated populations, or where the arguments for synonymy are considered unconvincing. Workers spending considerable time in the field, such as Allen & Erdmann (2012) have generally supported most of the species recognised by Kuiter (2001, 2009). Clearly additional work is needed before Australian species name stabilise.
