Plectreuridae have not been rigorously examined since 1958, with only three new species added to Plectreurys. This study revisited a subset of taxa from the genus Kibramoa using a combined morphological and multilocus phylogenetic analysis. Species distribution modeling (SDM) was used to investigate the current and paleo distributional patterns of the genus Kibramoa throughout the biodiverse region of the California Floristic Province (CFP). A reexamination of genitalic morphology reflected cryptic species, yet multilocus Bayesian and Maximum Likelihood analyses of mitochondrial (CO1, 16S) and nuclear (ITS1, 28S) markers consistently suggest several divergent lineages. A time-calibrated phylogeny indicated that the most recent common ancestor of Kibramoa appeared in the Mid-Miocene and continued to diversify throughout the Plio-Pleistocene. Xerophilic Kibramoa, as inferred by SDM, had a much wider distribution during the Mid-Holocene, when climate was at its warmest. This body of work uncovered novel findings regarding the evolution of plectreurids, provided the first phylogeny of the family, and demonstrated similar biogeographic patterns displayed in other CFP taxa.} }
