- Abstract
Seven new species of the planktonic copepod genus and subgenus Tortanus (Atortus) are described from North Sulawesi, Indonesia. Four of these species, T. (A.) indonesiensis, T. (A.) omorii, T. (A.) processus and T. (A.) lukmani, belong to the brevipes species complex sensu Ohtsuka & Kimoto (1989). Two species, T. (A.) sulawesiensis and T. (A.) manadoensis, can be placed in the recticauda species complex. The seventh species, however, T. (A.) bilobus, belongs to neither group, which will necessitate a revision of the current morphology-based grouping with the aid of a genetically-based phylogeny. The co-occurrence of multiple closely-related congeners in a relatively small area suggests possible microhabitat segregation among these species.
