摘要

新西兰Leiopelma frog的化石记录是不完整的，以前报道的化石仅来自中新世早期(16-19 Mya)和第四纪晚期(过去20 Ka)。本文描述了南岛东部上新世晚期(3.7-2.4 Ma)的Leiopelma bishopi n. sp.。该地区蛙类的灭绝可能是由于南阿尔卑斯山的隆起和更新世冰河时期的降温导致的干旱加剧。这个独特的上新世陆生化石位置的发现为西兰迪亚的动态气候和地质历史如何塑造其最近生物群的进化提供了新的和重要的见解，特别是对于具有较差的前第四纪化石记录的群体。LSID: urn: LSID: zoobank.org:pub:457F4C99-A561-4C3B-802C-3412EA3D7D42缩写:SVL:鼻口长度;NMNZ:新西兰博物馆the Papa Tongarewa，惠灵顿，新西兰;怀托摩洞穴博物馆，怀托摩，新西兰

A new species of Leiopelma frog (Amphibia: Anura: Leiopelmatidae) from the late Pliocene of New Zealand

ABSTRACT The fossil record of Leiopelma frogs in New Zealand is patchy, with remains previously reported only from the early Miocene (16–19 Mya) and late Quaternary (past 20 Ka). Here we describe Leiopelma bishopi n. sp. from the late Pliocene (3.7–2.4 Ma) of the eastern South Island. The subsequent extinction of frogs in this region is likely due to increased aridity following uplift of the Southern Alps and cooling associated with the Pleistocene Ice Ages. Discoveries from this unique Pliocene terrestrial fossil locality provide new and significant insights into how the dynamic climatic and geological history of Zealandia has shaped the evolution of its recent biota, especially for groups with a poor pre-Quaternary fossil record.

期刊介绍： Aims: The diversity of the fauna of the southern continents and oceans is of worldwide interest to researchers in universities, museums, and other centres. The New Zealand Journal of Zoology plays an important role in disseminating information on field-based, experimental, and theoretical research on the zoology of the region.
