Abstract

The genus Conidiobolus is an important group in entomophthoroid fungi and is considered to be polyphyletic in recent molecular phylogenies. To re-evaluate and delimit this genus, multi-locus phylogenetic analyses were performed using the large and small subunits of nuclear ribosomal DNA (nucLSU and nucSSU), the small subunit of the mitochondrial ribosomal DNA (mtSSU) and the translation elongation factor 1-alpha (EF-1α). The results indicated that the Conidiobolus is not monophyletic, being grouped into a paraphyletic grade with four clades. Consequently, the well-known Conidiobolus is revised and three new genera Capillidium, Microconidiobolus and Neoconidiobolus are proposed along with one new record and 22 new combinations. In addition, the genus Basidiobolus is found to be basal to the other entomophthoroid taxa and the genus Batkoa locates in the Entomophthoraceae clade.
