  Advancing the systematics of Araneae: ultraconserved elements phylogenomics demonstrates the non-monophyly of Miturgidae Simon, 1886 and supports the Familial Rank of Systariidae Deeleman-Reinhold, 2001 Abstract The systematic status of the family Miturgidae Simon, 1886 and related subfamilies has long been problematic, primarily due to challenges in interpreting morphological characters and limited molecular sampling. In this study, we reconstruct the phylogeny of Miturgidae using ultraconserved elements and estimate its divergence time. Our results suggest that Systariinae does not belong to Miturgidae, but rather is sister to all other families of the Dionycha B clade. Consequently, we elevate it to family rank as Systariidae Deeleman-Reinhold, 2001 and discuss its morphological synapomorphies. Furthermore, our analyses place Miturgidae as the sister clade to Viridasiidae + Selenopidae under multiple phylogenetic methods. Divergence time estimates indicate an ancient origin of...
