Antoine Alphonse Guichenot (31 July 1809 in Paris – 17 February 1876 in Cluny) was a French zoologist who taught, researched, and participated in specimen collecting trips on behalf of the Muséum national d'histoire naturelle (Paris), including an extensive biological survey of Algeria.
His primary fields of research included fish and reptiles. He is credited with describing the ichthyological genera Agonomalus,[1] Neosebastes (gurnard scorpionfishes)[2][3] and Glossanodon.[4] He also described numerous new species, including the New Caledonian crested gecko, Correlophus ciliatis (changed to Rhacodactylus ciliatus in 1994, but reclassified as Correlophus ciliatis in 2012).[5]
He retired to solely an assistant naturalist position in 1856, and died in 1876 in Cluny, France.
