EUCYCLOPINAE Kiefer, 1927


TROPOCYCLOPS Kiefer, 1927


The genus Tropocyclops, with a predominantly tropical-subtropical range, includes small to very small species that predominantly occupy the weedy littoral of lakes and ponds. A few species occur in the limnetic zone of large lakes.

The genus presently includes 45 named species and subspecies, widely distributed, mostly in fresh water bodies.

Recently Alekseev et al. (2013) for the endemic cyclopoid Tropocyclops matanoensis Defaye, 2007, proposed a new subgenus, Defayeicyclops [PDF] .
