The name François-Louis Laporte, comte de Castelnau serves as a primary reference for botanical and zoological nomenclature, particularly within the study of coleoptera. Born in London in 1802, he balanced a career as a diplomat for France with extensive scientific exploration across South America, Africa, and Australia, eventually holding the position of consul general in Melbourne.
Scientific Expeditions
Following studies in Paris, he traveled through the United States, Texas, and Canada between 1837 and 1841. He focused on the fauna of Canadian lakes and river systems. In 1843, Louis Philippe commissioned him to lead an expedition across South America. Over five years, he surveyed the watershed between the Amazon and La Plata river systems, spanning from Rio de Janeiro to Lima and finishing at Pará. During this transit, he compiled linguistic records of indigenous groups including Bororoan and Guachi.

His career included several consular appointments. He served in Bahia in 1848, followed by a tenure in Siam between 1856 and 1858. By 1864, he moved to Melbourne, Australia, where he performed consular duties until 1877. During his time in the Cape of Good Hope in 1856, he reached Algoa Bay and subsequently authored a 1861 treatise regarding fish species in South Africa.
Publications and Taxonomic Legacy
His bibliography includes Histoire naturelle (1837), Vues et souvenirs de l'Amérique du Nord (1842), and the 1843 Essai sur la Floride du Milieu. He collaborated with Hippolyte Louis Gory on the multi-volume Histoire naturelle et iconographie des insectes coléoptères, issued between 1837 and 1841. His contributions to taxonomy are preserved in the plant genus Laportea, the spotback skate Atlantoraja castelnaui, and various beetle and gecko species.
The Ompax Spatuloides Incident
During his residency in Australia, he was involved in a biological misidentification concerning a supposed ganoid fish called Ompax spatuloides. The description originated from a sketch provided by Karl Staiger, the director of the Brisbane Museum in 1872. Castelnau described the specimen in good faith, unaware the report was a practical joke directed at Staiger.
