A coccoid green alga, Hemiflagellochloris kazakhstanica S. Watanabe, S. Tsujimura, T. Misono, S. Nakamura et H. Inoue, gen. et sp. nov., was described from soil samples of a saline irrigation land in Ili River basin, Kazakhstan. This alga had a parietal chloroplast with a pyrenoid, which was covered with starch segments and penetrated with thylakoid membranes. Reproduction occurred by the formation of aplanospores and zoospores. The aplanospores frequently formed tetrad aggregations in a mother cell. The zoospores were covered by a single-layered cell wall and lacked stigmata. The zoospores had two flagella of considerably unequal lengths; the longer flagellum was 17–19 lm in length and the shorter one was 9–10 lm. The flagellar apparatus architecture was of the clockwise orientation group type in the Chlorophyceae. Molecular phylogenetic analysis using 18S and 28S rDNA sequence data resolved this organism in a separate clade from the green algae that had flagella of slightly unequal lengths. It was suggested that features such as inequality in flagellar lengths, parallel exsertion of basal bodies, and subapical position of the flagellar apparatus were sporadically evolved.
