Abstract

Abstract. The genus Anamycetaea Strohecker, 1975, established for Anamycetaea keralae, a single species from India, was originally placed in the diverse endomychid subfamily Mycetaeinae and has subsequently been considered a member of the subfamily Anamorphinae based on closed mesocoxal cavities, a postulated synapomorphy of this group. Recent molecular research resulted in raising Anamorphinae to family level and revealed this group to be distantly related to Endomychidae sensu stricto. However, Anamycetaea has been ‘neglected’ since description. Our detailed study of this genus has been possible due to new material collected from Oriental and Australian regions. Striking overall similarity to the endomychine genus Tharina and a tentorium with anterior arms fused medially (separated in almost all Anamorphidae) have raised our doubts and led to further investigation of the phylogenetic placement of this enigmatic genus within Endomychidae sensu lato (handsome fungus beetles). Phylogenetic analyses of molecular and morphological datasets were conducted under Bayesian (BI), maximum likelihood (ML) and parsimony (MP) frameworks. Our results recovered Anamycetaea as belonging to the family Endomychidae, in the subfamily Endomychinae, distant from Anamorphidae. The close affinity to Stenotarsus and allies was strongly supported in all analyses. Based on material studied, A. keralae is described in detail here and includes description of previously unknown male genitalia. Four new species are also described, extending the ragne of the genus to the Australian region: Anamycetaea borneensis sp. nov. (from Borneo), A. novoguineensis sp. nov. and A. papuensis sp. nov. (from Papua New Guinea) and A. queenslandica sp. nov. (from Australia). Illustrations of morphological details and diagnoses are provided for each species. A key to the species of the genus is also presented. ZooBank: urn:lsid:zoobank.org:pub:90BAA954-7849-4FA9-997B-061FE7BB5702

“我的家人在哪里?”分子和形态学资料揭示了神秘的帅气真菌甲虫属Anamycetaea Strohecker, 1975(鞘翅目，瓢虫总科)的系统发育位置和多样性

摘要Anamycetaea Strohecker, 1975年，为印度Anamycetaea keralae这一单一物种建立，最初被置于Mycetaeinae亚科中，随后被认为是Anamorphinae亚科的成员，基于封闭的中端腔，这是一种假设的类群的突触形态。近年来的分子研究结果表明，Anamorphinae已上升至科，与Endomychidae sensu stricto有亲缘关系。然而，自描述以来，anamycetae一直被“忽视”。由于从东方和澳大利亚地区收集的新材料，我们对该属的详细研究成为可能。与内生菌属Tharina的惊人整体相似性和前肢中间融合的触角(在几乎所有的变形科中都是分开的)引起了我们的怀疑，并导致了对这一神秘属在内生菌科sensu lato(英俊的真菌甲虫)中的系统发育定位的进一步研究。在贝叶斯(BI)、最大似然(ML)和简约(MP)框架下对分子和形态数据集进行系统发育分析。我们的研究结果表明，该昆虫属于内圆虫科，属于内圆虫亚科，与变形虫科有一定距离。所有的分析结果都强烈支持其与窄跗骨及其亲缘的亲缘关系。根据研究的材料，这里详细描述了A. keralae，包括对以前未知的男性生殖器的描述。另外还发现了4个新种，将该属的分布范围扩大到澳大利亚地区:Anamycetaea borneensis sp. 11 .(来自婆罗洲)、A. novoguineensis sp. 11 .和A. papuensis sp. 11 .(来自巴布亚新几内亚)和A. queenandica sp. 11 .(来自澳大利亚)。插图的形态细节和诊断提供了每个物种。还提出了该属的种的钥匙。ZooBank: urn: lsid zoobank.org:酒吧:90 baa954 - 7849 - 4 - fa9 - 997 b - 061 fe7bb5702

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.
