Auchenipterus
''Auchenipterus'' is a genus of driftwood catfishes (order Siluriformes). Taxonomy The genus is hypothesized to be monophyletic, diagnosed by the shared presence of grooves in the ventral surface of the head that accommodate adducted mental barbels. The presence of papillae on the dorsal and medial surface of the ossified maxillary barbel of mature males is also a possible synapomorphy, but in three species In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of ... this cannot be confirmed as there are no adult male specimens yet discovered.

Driftwood Catfish
The driftwood catfishes are catfishes of the family Auchenipteridae. The two genera of the former family Ageneiosidae have been placed here, resulting in a grouping of about 125 species in about 22 genera. These fish are found in rivers from Panama to Argentina, commonly in river flood plains. All but one species have three pairs of barbels, with the nasal barbels absent. Most species have very small adipose fins. While ''Ageneiosus inermis'', also known as the fidalgo, is known to reach in length, most are small, with some species not known at any longer than . The eggs are fertilised internally. Driftwood catfishes are nocturnal. Some of the smaller species are known to hide in logs and crevices during the day, and come out to feed at night. Some larger species can consume fruits and insects, and are probably omnivorous. Fish of this family seem to feed primarily on insects, but also eat fish, shrimp, fruit, and even filamentous algae Algae (; singular alga ) is an inform ...

Franz Hermann Troschel
Franz Hermann Troschel (10 October 1810 – 6 November 1882) was a German zoologist born in Spandau. He studied mathematics and natural history at the University of Berlin, where he was awarded his doctorate in 1834.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Troschel", p. 268). From 1840 to 1849 he was an assistant to Martin Lichtenstein at the Natural History Museum of Berlin. In 1849 he became a professor of zoology and natural history at the University of Bonn. In 1851 he became a member of the Academy of Sciences Leopoldina. ''Deutschen Akademie der Naturforscher Leopoldina''.
