I found the only available genus for the clade containing the Hourglass and Peale's Dolphins is Sagmatias Cope, 1866. [1] Therefore, Lagenorhynchus cruciger, L. australis, L. obliquidens, and L. obscurus should be changed to Sagmatias cruciger, S. australis, S. obliquidens, and S. obscurus respectively.

I would like to open a discussion on the systematics of the genus Lagenorhynchus. While there is little doubt that the genus is polyphyletic and a reorganisation is needed, there is not yet consensus on how this should be done. The de facto authority on cetacean taxonomy, the Society for Marine Mammalogy's Taxonomic Comittee still include six species in the genus in the list of marine mammal species:
Currently the organisation of pages on these species follows a recent publication: Vollmer, et al. (2019) Taxonomic revision of the dolphin genus Lagenorhynchus. Marine Mammal Science., which inclues resurrection of the geni Leucopleurus and Sagmatias. The main problem with the genus Sagmatias as proposed by Vollmer, et al. (2019), is that it may be paraphyletic, because the authors do not address the possibility that hourglass dolphin and Peale's dolphin may be closer related to the genus Cephalorhynchus than to dusky dolphin and Pacific white-sided dolphin. Thus, as long as this has not been settled by the taxonomic committee, the nomenclature should follow the traditional inclusion of all six species in Lagenorhynchus, with approriate description of the taxonomic issues on the relevant pages.

@ Geekgecko, JakobT, and Cygnis insignis: Until there is a well-established idea of what kind of genera Lagenorhynchus should be divided into, I suggest making Sagmatias and Leucopleurus redirects to this page. All information about these genera so far can be presented here. HFoxii ( talk) 03:11, 23 August 2022 (UTC)
