FIGURE 1. Distribution of the Elminiinae and early Tetraclitoidea. The earliest record of the Elminiinae is the four plated Protelminius pomahakensis from the Rupelian (early Oligocene) of New Zealand. Assuming a six-plated ancestor to this taxon, parsimony requires a Hexaminius-type first occurring in eastern Australia during the Eocene, from which the four-plated form evolved and dispersed across a proto-Tasman Sea to New Zealand. If Hexaminius had occurred in New Zealand, it would not be unreasonable to expect it in the present warmer northern waters. It was most likely during the Oligocene to early Miocene that Elminius dispersed to South America (shaded arrow); with colonization of the Falkland Islands and the eastern seaboard of South America being facilitated by the opening of the Drake Passage, which had occurred by that time (Scher and Morris, 2006). The dotted line shows the very recent distribution path for Austrominius modestus from Australasia to Europe; although there is a report of single ... : Published as part of Buckeridge, John S. & Newman, William A., 2010, A review of the subfamily Eliminiinae (Cirripedia: Thoracica: Austrobalanidae), including a new genus, Protelminius nov., from the Oligocene of New Zealand, pp. 39-54 in Zootaxa 2349 on page 43, DOI: 10.5281/zenodo.275597 ...
