Carapace in lateral view subtriangular, greatest height in front of the middle, slightly more than half of the total length. Anterior margin broad, posterior margin narrower, but rounded. Ventral margin slightly concave with a rounded expansion in the mouth area, and slightly enlarged frontally. In dorsal view carapace oval, anterior end pointed, posterior bluntly rounded. Lateral sides only slightly arched. LV overlaps RV along entire free margin. Two conspicuous inner lists running parallel on the inner calcified lamella, more pronounced in the anterior part. Maxillary palp with cylindrical terminal palp segment, about twice as long as broad. Two teeth setae of the third maxillary endite serrate. Maxilliped (T 1) with c-seta. Walking leg (T 2) with only one seta (d 1) at the basal segment. Included species: Type species: Arctocypris fuhrmanni n. gen. , n. sp. Other species: A. arctica (Olofsson, 1918) comb. nov; A. foveata (Delorme, 1968) comb. nov.; A. dulcifons (Diebel & Pietrzeniuk, 1969) comb. nov. : Published as part of Petkovski, Trajan K., Scharf, Burkhard & Keyser, Dietmar, 2016, Arctocypris fuhrmanni, n. gen., n. sp.
