Jumping spiders (Salticidae) are a diverse group, and understanding their evolutionary relationships is crucial for biodiversity studies. This research addresses the classification of an enigmatic lineage within the subtribe Spartaeina, previously unresolved due to limited specimens. With the updated phylogeny using ultraconserved element data, we provided a solid phylogenetic framework for Spartaeina and established a new genus, Protaeus. These findings enhance our knowledge of phylogeny and diversity of Spartaeina, and highlight the need for further exploration in this fascinating group. (Image credit: Yi Ni.)

A new millipede species Pericambala foveiformis, sp. nov. is described using integrated methods. The mitogenome of P. foveiformis with 17,467 bp in length, is the largest millipede mitogenome currently known. Molecular phylogenies provided new insights into the phylogenetic relationships of higher taxa within the order Spirostreptida. (Image credit: Liang Li.)
