CYCLOPS KOLENSIS ALASKAENSIS LINDBERG, 1956, REVISITED (COPEPODA: CYCLOPOIDA)

Copepods referable to Cyclops kolensis alaskaensis Lindberg, 1956, are known from about 10 tundra ponds in 4 locations in Alaska. These animals differ from the nominate form in the shape of the fourth and fifth prosomites, the shorter dorsal seta, the genital somite of subequal width and length, and...

Description
Summary:Copepods referable to Cyclops kolensis alaskaensis Lindberg, 1956, are known from about 10 tundra ponds in 4 locations in Alaska. These animals differ from the nominate form in the shape of the fourth and fifth prosomites, the shorter dorsal seta, the genital somite of subequal width and length, and a pronounced tendency toward reduction in the number of articles in the antennule. Relationships among Alaskan populations of C. kolensis and their relationships to populations of C. kolensis elsewhere cannot be completely resolved without recourse to electrophoretic or other nonmorphological data. In the meantime, Lindberg's trinomial calls attention to the similarities and differences of the North American and nominate forms.
