Shiraz University Press Molecular Biology Research Communications 2322-181X 15 2 2026 06 01 Molecular and Morphological evidence support the delimitation of a new genus, Hafezia gen. nov. in Arabideae (Brassicaceae) 117 130 8515 10.22099/mbrc.2025.54085.2198 EN Ahmad Reza Khosravi Department of Biology, College of Science, Shiraz University, Shiraz, Iran Atena Eslami-Farouji Department of Biology, College of Science, Shiraz University, Shiraz, Iran Journal Article 2025 09 08 Recent molecular phylogenetic analyses within the tribe Arabideae (Brassicaceae) have uncovered unresolved lineages that challenge current generic boundaries. In this study, we incorporate molecular data with morphological evidence to resolve a long-standing taxonomic ambiguity, resulting in the description of a new monophyletic genus, <em>Hafezia</em> gen. nov., together with two new combinations, <em>H. aucheri </em>(Boiss.) A.R. Khosravi & A. Eslami-Farouji<em> </em>and <em>H. parvula </em>(Dufour ex DC.) A.R. Khosravi & A. Eslami-Farouji<em>. </em>Integrative taxonomy and phylogenetic insights, such as indels and substitution nucleotide variants, confirm the distinct assignment of these taxa, previously misassigned to <em>Arabis</em> L. Morphological reassessment, including traits such as simple, long setaceous hairs, notched petals, winged stamens, not compressed, not subtorulose or torulose fruits, supports their separation. The new genus naturally grows in the Mediterranean and west of the Irano-Turanian floristic regions. Our findings highlight the significance of integration of taxonomic investigations with the molecular investigations in clarifying evolutionary relationships and provide a revised key for accurate identification within Arabideae. https://mbrc.shirazu.ac.ir/article_8515_991bc9ff9ae45909c50ec5f977388867.pdf
