Favoritos de alzen

From a shallow seasonal pool under willows. It keys to Cyclops using Gurney's 1933 book. Very fine comb of tiny hairs on the final antennule segments. Has some characters of strenuus and some of vicinus: furcae about 4x as long as wide and somites 4 and 5 not expanded would fit strenuus. Spermatophores were handlebar moustache pattern, as in Gurney's fig. 1520. But leg spine formula is 2 3 ? 3 (I didn't look at leg 3), and inner apical seta on furca is more than 2x length of outer, which fit vicinus.
