Introduction

This family of front-fanged venomous snakes occurs from Africa, through Asia and Indo-Malaysia to Australia and New Guinea, the Solomon Islands and Fiji, with one New World group (the coral snakes).

Following several genetic studies, the taxonomy of the elapid snakes currently accepted no longer separates terrestrial forms from the sea kraits and the sea snakes, but recognises only two major groups, one of which includes all Australian elapids, both terrestrial and marine (Lawson et al. 2005, Kelly et al. 2009, Pyron et al. 2010), which some authors identify with the subfamily Hydrophiinae Fitzinger, 1843 (e.g. Vidal et al. 2007).

Hydrophinae has currently more than 40 genera and approximately 200 species, most of them in Australia.

Several genera warrant special mention. The close relationship between the genera Furina and Glyphodon has long been recognised. Storr (1981) formally synonymised the two. We have somewhat arbitrarily retained their separate identity pending a more rigorous examination of their relationships. We also have rejected on morphological grounds Storr's transfer of Cacophis warro De Vis, 1884 to Furina; the relationships of Cacophis warro remain obscure but appear to lie with Simoselaps bertholdi. Recognition of the genus Parademansia to accommodate Diemenia microlepidota McCoy, 1879 is contrary to the conclusions of Covacevich et al. (1980) that this species is congeneric with the taipan, Oxyuranus scutellatus. This is largely a matter of interpretation of the available data (which were clearly documented by Covacevich et al. 1980), but we believe that the differences between the two taxa are such as to warrant generic separation.

The genus Simoselaps, as treated, is clearly polyphyletic and awaits effective revision. Intensive work is currently being undertaken on a variety of fronts — morphological, ecological, karyological and biochemical — to establish relationships within Australian elapids and between them and their relatives elsewhere. The classification adopted below should be seen, therefore, as an interim one. Sanders et al. (2013) studied the phylogeny of the viviparous sea snakes.

Rasmussen et al. (2014) listed all sea snakes known to occur in Australian waters, excluded a number of species, and also gave a short list of species that may eventually be found in Australian waters. The list included Hydrophis laboutei Rasmussen & Ineich, 2000, Hydrophis vorisi Kharin, 1984, Microcephalopis gracilis (Shaw, 1802) and a Laticauda sp. of Laurent, 1768. Their listing included many changed combinations, now used here, as a consequence of which, several genera were excluded from Australian waters.

Diagnosis

Characterised in Australia by: a pair of functionally hollow enlarged fangs at the front of the maxilla; no loreal scales; scales in 23 or fewer rows at mid-body.
