چکیده

Beauveria sinensis sp. nov. was isolated from a larva of Geometridae (Lepidoptera) collected from Tiantangzhai, Anhui province, China. It is characterized by elongated ellipsoidal to cylindrical conidia, solitary conidiogenous cells that are cylindrical or with slightly swollen bases, white to pale pink colony in culture, and small mycelial pellets consisting of curved hyphae. Phylogenetic analyses of translation elongation factor-1 alpha (TEF), RNA polymerase II largest subunit (RPB1), and RNA polymerase II second largest subunit (RPB2) sequence data support it as a unique species and sister to B. sungii. It does not, however, form a monophyletic group with other elongated ellipsoidal to cylindrical conidiaproducing species in Beauveria. Type isolates and holotype are deposited in the Research Center for Entomogenous Fungi of Anhui Agricultural University (RCEF).
