Abstract

ABSTRACT South-western Western Australia is a global biodiversity hotspot renowned for exceptional diversity of plants and animals. The evolutionary processes that have generated this high biodiversity are not always clear, particularly for invertebrates, yet the area supports a very large number of endemic species that have diversified in situ. We use an integrative taxonomic approach based on adult and immature morphology, ecology, behaviour and molecular data to investigate the taxonomic status of a sympatric but seasonally isolated form (Neolucia agricola occidens Waterhouse & Lyell, 1914 form ‘Julimar’) of the polyommatine butterfly Neolucia agricola (Westwood, 1851) in south-western Western Australia. Our molecular dataset comprised 112 samples representing all Neolucia Waterhouse & Turner, 1905 species (100 COI 5′ sequences, 658 bp, plus 12 COI 3′, tRNA Leu, COII and EF1-α sequences, 3303 bp). Maximum likelihood phylogenetic analysis of the combined dataset recovered form ‘Julimar’ and N. agricola as reciprocally monophyletic, with a mean uncorrected ‘p’ pairwise divergence of 5.77% for the ‘barcode’ region of COI. Based on this and other evidence we recognise form ‘Julimar’ as a new species, Neolucia bollami Eastwood, Braby & Graham, sp. nov., sister to N. agricola and endemic to south-western Western Australia. As a result of these findings, we evaluated the evolutionary history of the two Neolucia species in WA and the processes that may have contributed to the diversification in sympatry or allopatry. We conclude that the multiple effect traits associated with a host shift, including host fidelity and temporal divergence, played an important role in the diversification process and in maintaining the reproductive integrity of the nascent allochronic species.

Neolucia bollami Eastwood, Braby & Graham, sp. 11 .(鳞翅目:Lycaenidae科):来自西澳大利亚西南部的一种新的异时隐蝶

西澳大利亚州西南部是全球生物多样性的热点地区，以其独特的动植物多样性而闻名。产生这种高度生物多样性的进化过程并不总是很清楚，特别是对无脊椎动物来说，然而该地区支持了大量在原地多样化的特有物种。我们使用基于成虫和未成虫形态学、生态学、行为和分子数据的综合分类方法，调查了西澳大利亚西南部一种同域但季节性分离的多聚体蝴蝶(Neolucia agricola occidens Waterhouse & Lyell, 1914年形成的“jurimar”)的分类地位。我们的分子数据集包括112个样本，代表了所有新卢lucia Waterhouse & Turner, 1905个物种(100个COI 5 '序列，658 bp，加上12个COI 3 '， tRNA Leu, COII和EF1-α序列，3303 bp)。组合数据集的最大似然系统发育分析恢复了' Julimar '和N. agricola的相互单系性，COI '条形码'区域的平均未校正' p '成对差异为5.77%。基于这一点和其他证据，我们认识到“jurimar”是一个新种，Neolucia bollami Eastwood, Braby & Graham, spnov .，是N. agricola的姐妹，是西澳大利亚西南部的特有物种。基于这些发现，我们评估了西澳两种新卢西亚物种的进化史，以及可能导致同属或异属多样化的过程。研究结果表明，寄主转换相关的多重效应性状，包括寄主保真度和时间差异，在异种新生物种的多样化过程和维持生殖完整性方面发挥了重要作用。ZooBank: urn: lsid zoobank.org:行动:53 d9ad14 - 9694 - 4 - b5e - 889 c - a8d533e7f57d

期刊介绍： Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance. Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems. Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
