Abstract

A new species, Cryptomonas cattiensis sp. nov., is described from Vietnam based on morphological and molecular data. Phylogenetic relationships inferred from nuclear small and large subunit ribosomal DNA, internal transcribed spacer 2, and plastid psbA sequences show that the new species forms a separate branch on the phylogenetic tree of the genus Cryptomonas. This species has slightly sigmoid to elliptical cells in ventral view and a single plastid, deeply notched into several irregular lobes, with two pyrenoids. C. cattiensis has been observed in one locality in Cat Tien National Park.
