Urophycis chuss (Walbaum, 1792)

Marancik, Katrin E., Richardson, David E. & Konieczna, Małgorzata, 2020, Updated Morphological Descriptions of the Larval Stage of Urophycis (Family: Phycidae) from the Northeast United States Continental Shelf, Copeia 108 (1), pp. 83-90 : 84

Separating Urophycis chuss , U. regia , and U. tenuis from other phycids.— There is one closely related lotid ( Enchelyopus cimbrius ) and seven species of Phycidae in the northwest Atlantic: Phycis chesteri , Urophycis chuss , U. cirrata , U. earlli , U. floridana , U. regia , and U. tenuis . Enchelyopus cimbrius is easily distinguished from larvae of Urophycis based on a melanophore on the ventral notochord tip and four pelvic rays versus three on larvae of Urophycis ( Markle, 1982) . Phycis chesteri , U. cirrata , U. earlii , and U. floridana rarely occur on the northeast U.S. shelf, spawn in late fall or early spring, and are not included in the following descriptions, which are based on larvae collected from May to November ( Comyns and Bond, 2002; Fahay, 2007).
