ABSTRACT This paper records an exotic collembolan the species, Anurophorus laricis Nicolet, 1842, found for the first time in New Zealand. Its specific identity is confirmed using morphological data. The record is significant because it is the first for the genus Anurophorus in the Southern Hemisphere. Moreover, the species was found fairly abundantly on the native shrub, manuka, at 300 m asl, an unusual habitat for an exotic species. The high number of exotic, mainly European but also North American, species identified on morphological grounds found in Australia and New Zealand, has not in the past been accepted as valid by taxonomists in Europe. Confirmation using molecular sequence data has only recently been possible and was attempted but was not successful. A related issue is that there has been a trend of Salmon’s New Zealand endemic isotomids, both genera and species, being recognised as exotic after revision. We propose likely attributes of species and habitats that facilitate colonisation of exotic species in New Zealand which should help conservation efforts to be well focused.

新西兰新出现的外来弹跳虫属和种（Isotomidae：Anurophorinae）

摘要 本文记录了 1842 年首次在新西兰发现的外来弹尾目 Anurophorus laricis Nicolet。使用形态学数据确认其特定身份。该记录意义重大，因为它是南半球 Anurophorus 属的第一个记录。此外，在海拔 300 米的本地灌木麦卢卡上发现了相当丰富的物种，这是外来物种的不寻常栖息地。在澳大利亚和新西兰发现的大量外来物种，主要是欧洲物种，但也包括北美物种，这些物种过去并未被欧洲的分类学家认为是有效的。直到最近才可能使用分子序列数据进行确认，并进行了尝试，但没有成功。一个相关的问题是，三文鱼的新西兰特有异种类有一种趋势，包括属和种，经过修订后被认为是外来物种。我们提出了有助于新西兰外来物种殖民的物种和栖息地的可能属性，这应该有助于保护工作的重点。
