Phylogenomic placement of a new genus and species of jumping spiders (Araneae: Salticidae: Spartaeini) based on UCE data.
Recent phylogenomic studies have established a robust backbone relationship for the seven subfamilies of jumping spiders (Salticidae), and identified an enigmatic clade within the subtribe Spartaeina, a major lineage of the subfamily Spartaeinae. However, the classification of this enigmatic clade remained unresolved due to the availability of only one male specimen at that time. In this study, we extensively examined additional materials and obtained ultraconserved element (UCE) data for more putative species of this lineage. The UCE phylogenetic results provided a comprehensive and strongly supported framework for the subtribe Spartaeina, and confirmed that the enigmatic clade is a distinct lineage, separate from genera with similar morphological traits. Coupled with morphological evidence, we describe a new genus, Protaeus gen. nov., and three new species: Protaeus nyarlathotep sp. nov., P. dracosquamus sp. nov., and P. gulliwingus sp. nov. We also revise the classification of three previously misplaced species into this new genus: P. jianfeng (Song & Zhu, 1998) comb. nov. (transferred from Portia ), P. forcipiformis (Yang, Liu, Liu & Peng, 2017) comb. nov. (transferred from Spartaeus ) and P. shiwandashan (Wang, Mi, Li & Xu, 2024) comb. nov. (transferred from Mintonia ). Additionally, we redescribe the male of P. jianfeng and provide a description of the female for the first time. This study enhances our understanding of evolutionary relationships within Spartaeina and underscores the importance of further exploration within this diverse group.

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.
