Revision of the Remaneicaris Argentina-group (Copepoda, Harpacticoida, Parastenocarididae): Supplementary description of species, and description of the first semi-terrestrial Remaneicaris from the tropical forest of Southeast Mexico
Remaneicaris is a species-rich Neotropical monophyletic group, easily recognized by the synapomorphic position of the outer seta of the third exopodite of leg 4, localized at 2/3 of the outer margin. The genus, comprising 35 species in five monophyletic groups, plus R. ignotus and R. meyerabichi, re...
