Datasets from the mitochondrial gene regions NADH dehydrogenase subunit I (ND1) and cytochrome c oxidase subunit I (COI) of the 20 species in the New Zealand wolf spider (Lycosidae) genus Anoteropsis were generated. Sequence data were phylogenetically analysed using parsimony and maximum likelihood analyses. The phylogenies generated from the ND1 and COI sequence data and a previously generated morphological dataset were significantly congruent (p<0.001). Sequence data were combined with morphological data and phylogenetically analysed using parsimony. The ND1 region sequenced included part of tRNA(Leu(CUN)), which appears to have an unstable amino-acyl arm and no TpsiC arm in lycosids. Analyses supported the existence of five species groups within Anoteropsis and the monophyly of species represented by multiple samples. A radiation of Anoteropsis species within the last five million years is inferred from the ND1 and COI likelihood phylograms, habitat and geological data, which also indicates that Anoteropsis arrived in New Zealand some time after it separated from Gondwana.
生成了新西兰狼蛛（狼蛛科）Anoteropsis属20个物种的线粒体基因区域烟酰胺腺嘌呤二核苷酸脱氢酶亚基I（ND1）和细胞色素c氧化酶亚基I（COI）的数据集。使用简约法和最大似然法对序列数据进行了系统发育分析。从ND1和COI序列数据以及先前生成的形态学数据集生成的系统发育树具有显著的一致性（p<0.001）。将序列数据与形态学数据相结合，并使用简约法进行系统发育分析。测序的ND1区域包括部分tRNA（Leu（CUN）），在狼蛛科中，其似乎具有不稳定的氨酰臂且没有TpsiC臂。分析支持了Anoteropsis属内存在五个物种组以及多个样本所代表物种的单系性。从ND1和COI似然系统发育图、栖息地和地质数据推断，Anoteropsis物种在过去五百万年内发生了辐射分化，这也表明Anoteropsis在新西兰从冈瓦纳大陆分离后的某个时间到达了新西兰。
