Alexandr Vladimirovich Gussev (Александр Владимирович Гусев, 5 July 1917 – 31 December 1999), sometimes spelled Gusev in the literature, was a Russian helminthologist specialist of monogeneans.
Gussev wrote more than 220 publications, dealing with systematics, faunistics, morphology, development, biology and zoogeography of fish parasites.
Gussev is mainly known for his work on the Monogenea, a group of Platyhelminthes parasitic on freshwater and marine fish.
However, the species names Lepeophtheirus gusevi Moon & Kim, 2012, a copepod, and Neopavlovskioides gusevi Rodyuk, 1986, a monogenean, are based on the spelling with a single s. Gussev is also honoured by a genus name, Gussevia Kohn & Paperna, 1964.
[5] Gussevia was considered a junior synonym of Urocleidoides Mizelle and Price, 1964 by Kritsky and Thatcher in 1983 [6] but was resurrected [7] and is now valid.
