Smallest to largest - 4 taxa sorted by maximum length
Eucconeis frustules are bent about the median transapical plane, including a twisted, sigmoid central sternum. As a member of the monoraphid group, the frustules are heterovalvar and differ in ornamentation between the raphe valve and rapheless valve.
Eucocconeis species occur commonly in the littoral zone of oligotrophic lakes, within epipelic, epipsammic, or epilithic habitats. Some species occur on wet walls.
