Duringlanis is a small, little-known genus of South American catfish usually placed among the banjo catfishes, family Aspredinidae, a group named for a flattened, guitar- or banjo-shaped body outline. Banjo catfish of this kind are bottom-dwellers of slow, sluggish water and leaf-litter-strewn margins, where a mottled brown coloring and flattened profile let them lie motionless and pass for a dead leaf or piece of debris, a camouflage strategy rather than an active-swimming lifestyle. The atlas's two species, Duringlanis romani and Duringlanis simplex, are recorded from Brazil and Venezuela and are notably small even for the family, at only 1.5–2 in.
Duringlanis is essentially unknown outside ichthyological collections; at this size, and with this little documented natural history, it has no meaningful presence in the aquarium trade, and the atlas's coverage here is a matter of taxonomic completeness rather than hobby relevance. Both species are currently assessed as Least Concern, and detailed information on their diet, breeding, and day-to-day habits in the wild remains sparse.
