The identification of two new species, <i>Paragibellulopsissinensis</i> and <i>Phialoparvumsinense</i>, was achieved by analyzing morphological characteristics and phylogenetic data obtained from four molecular markers (ITS, LSU, <i>rpb2</i>, and <i>tef-1α</i>). Morphologically, <i>Pa.sinensis</i> possessed short conidiogenous cells and aseptate and smaller conidia. On the other hand, <i>Ph.sinense</i> had obovate conidia and longer phialides. Phylogenetic analysis revealed that <i>Pa.sinensis</i> formed an independent branch as a sister species to <i>Pa.chrysanthemi</i>, whereas <i>Ph.sinense</i> clustered in a monophyletic clade with a sMycoKeys207-224https://www.ebi.ac.uk/biostudies/studies/S-EPMC12166386biostudies-literatureTwo new acremonium-like species, <i>Paragibellulopsissinensis</i> sp. nov. and <i>Phialoparvumsinense</i> sp. nov.
