摘要

Eofavartia Merle, 2002(腹足目:鼠足科)的古地理分布范围一直局限于北大西洋始新世(伊波斯纪至普里亚伯纪)，该属似乎在普里亚伯纪之后灭绝。来自印度尼西亚爪哇中新世中期的E. dharmai十一月sp.的描述揭示了Eofavartia在新近纪在印度-太平洋地区的持续存在。此外，对先前分别归属于Murexiella和Subpterynotus的三个南澳大利亚物种:M. perculta Vokes, 1985(下中新世)，S. antecedens (Ludbrook 1958)(上新世)和S. tatei (Verco 1895)(最近)的重新鉴定表明，它们与E. dharmai 11 . sp.和Eofavartia的欧洲和北美古近系物种在形态上更接近。对Eofavartia的属重新分配扩大了该属的范围，包括南澳大利亚。现存的E. tatei代表了该属的最后一个成员，在这里被认为是Eofavartia的孑遗种。

Review of the paleobiogeography of Eofavartia Merle, 2002 (Gastropoda: Muricidae) with the description of a new species from the Miocene of Java (Indonesia)

The paleobiogeographic range of Eofavartia Merle, 2002 (Gastropoda: Muricidae) was until now restricted to the Eocene (Ypresian to Priabonian) of the North Atlantic Ocean and the genus seemed to become extinct after the Priabonian. The description of E. dharmai nov. sp. from the Middle Miocene from Java (Indonesia) reveals the persistence of Eofavartia during the Neogene in the Indo-Pacific region. In addition, the critical reexamination of three South Australian species previously attributed to Murexiella and Subpterynotus respectively: M. perculta Vokes, 1985 (Lower Miocene), S. antecedens (Ludbrook 1958) (Pliocene) and S. tatei (Verco 1895) (Recent) shows closer morphological affinities to E. dharmai nov. sp. and the European and North American Paleogene species of Eofavartia. The generic reassignment to Eofavartia expands the range of the genus to include South Australia. The extant E. tatei represents the last member of the genus, and is herein considered a relict species of Eofavartia.
