Five ballistoconidiogenous yeast strains, isolated from plant leaves at Cuc Phuong National Forest of Ninh Binh, Vietnam, were assigned to the genus Kockovaella based on morphological and chemotaxonomical characteristics. They represent four new species based on analyses of 18S rDNA sequence, sequences of internal transcribed spacer regions, and DNA-DNA reassociation experiments. Four new species, Kockovaella calophylli (1 strain), Kockovaella cucphuongensis (2 strains), Kockovaella litseae (1 strain), and Kockovaella vietnamensis (1 strain) are proposed for these strains.
