Rehner, Stephen A. , Marilena Aquino de Muro & Joseph W. Bischoff. Description and phylogenetic placement of Beauveria malawiensis sp. nov. (Clavicipitaceae, Hypocreales). Mycotaxon 98: 137 - 145. 2006.

ABSTRACT: A new entomopathogenic species, Beauveria malawiensis, is described.  Beauveria malawiensis was isolated from a cadaver of Phoracantha semipunctata (Coleoptera: Cerambycidae) collected in Zomba, Malawi. Morphologically, B. malawiensis is distinguished by its pink colony color, the terminal and intercalary clusters of inflated conidiophores that each gives rise to multiple rachiform conidiogenous cells, and holoblastic cylindrical conidia.  Phylogenetic analysis of nuclear ribosomal internal transcribed spacer and translation elongation factor-1 alpha sequences place B. malawiensis apart from other species in the genus that also produce cylindrical conidia, supporting its proposed species status.
