Chroomonas reflexa is a species of cryptophyte alga in the family Chroomonadaceae, documented from freshwater environments in Europe. The specific epithet reflexa, meaning bent back or reflexed, likely refers to a characteristic curvature or reflex in the cell shape, flagella, or their attachment relative to the cell body. Cell shape and the arrangement of the ventral groove and flagellar insertion point are important taxonomic characters within the genus Chroomonas, and subtle morphological differences distinguish species that are otherwise similar in size and pigmentation. Chroomonas species are biflagellate, olive-green to brown or blue-green in color, and occur singly in the plankton and periphyton of freshwater systems. They are important components of microbial food webs, converting solar energy into organic biomass that is transferred to heterotrophic consumers. Cryptophytes are among the most nutritionally rich microalgae, containing elevated levels of long-chain polyunsaturated fatty acids (PUFAs) including EPA and DHA, making them highly valuable as food for zooplankton. Chroomonas reflexa has been recorded from European freshwater habitats. It has not been assessed by the IUCN.
