摘要：

The species of Acanthocyclops with 17-segmented antennules are a subtly variable group in Wisconsin. Principal Components Analysis of 313 individuals suggests there are 3 distinct species. Two of these species, A. vernalis and A. brevispinosus, show little or no within-species morphological variation. The third species, A. robustus, expresses a range of spininess, depending on the season. Descriptions and a key are provided for the Wisconsin species.
