# Alexandr Vladimirovich Gussev

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 was a student of the soviet parasitologist V. A. Dogiel. He worked at the Zoological Institute in Leningrad, then Saint Petersburg, Russia. He received his PhD in 1953 and his DrSc in 1973. 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. He was one of the world leader in this field and described more than 200 new species of monogeneans. He also authored a handbook on methods of collecting monogeneans.

## Honours

* Certificate of Honour from the Preasidium of the Academy of Sciences of the USSR
* Honorary member of the American Society of Parasitologists (1978)
* Honorary member of the Czechoslovakia Parasitological Society (1990)

## Political engagement

Gussev protested against the invasion of Czechoslovakia by Soviet forces in 1968.

## Taxa named on his honour

Although a simple transliteration of his name in Russian (Гусев) is Gusev (with a single s), the pronunciation in Russian is Gussev (as with two s) and citations in the Western literature generally use this spelling. Hence, the many taxa created in the honour of Gussev are usually named gussevi. The list of species includes Ancyrocephalus gussevi Dontsov, 1972, Bravohollisia gussevi Lim, 1995, Calydiscoides gussevi Oliver, 1984, Cosmetocleithrum gussevi Kritsky, Thatcher & Boeger, 1986, Dactylogyroides gussevi Hossain, Chandra & Mohanta, 2001, Dactylogyroides gussevia Singh, Anuradha & Arya, 2003, Diplozoon gussevi Glaser & Glaser, 1964, Dogielius gussevi Singh & Jain, 1988, Gyrodactyloides gussevi Bychowsky & Polyansky, 1953, Lamellodiscus gussevi Sanfilippo, 1978, Ligophorus gussevi Miroshnichenko & Maltsev, 2004, Mazocraes gussevi Agrawal & Sharma, 1989, Microcotyle gussevi Gupta & Krishna, 1980, Protogyrodactylus gussevi Bychowsky & Nagibina, 1974, Silurodiscoides gussevi Singh, Kumari & Agrawal, 1992, Trianchoratus gussevi Lim, 1987. All these species names designate monogeneans. 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. Gussevia was considered a junior synonym of Urocleidoides Mizelle and Price, 1964 by Kritsky and Thatcher in 1983 but was resurrected and is now valid. Gussevia is a genus of monogenean parasites of Neotropical cichlid fishes.
