Description
This study presents the first comprehensive investigation of chrysophytes from the Philippines. The flora of silica-scaled chrysophytes from freshwaters of Mindanao Island has been studied by means of scanning and transmission electron microscopy. A total of thirty-six taxa were recorded, including three belonging to Paraphysomonas, two to Spiniferomonas, one to Lepidochromonas, twenty-nine to Mallomonas and one to Synura. A new species, Mallomonas pseudopustula sp. nov., was discovered and described. Several unidentified Mallomonas taxa were also recorded. The flora of silica-scaled chrysophytes of the Mindanao Island is similar to the flora of neighbouring countries — Vietnam, Indonesia and Malaysia.
