Discussion:

This is one among the most diminutive species of the genus. It is very closely related to certain species of the genus Chroococcus, and it is difficult to state the distinguishing characteristics of such border-line organisms. This is particularly true of the material of no. 55 a, which is not absolutely identical with the type, no. 866, but too close to be separated specifically.
