Xyliphius live
buried in the sand and perhaps gravel of swift flowing streams.
The banjo catfish genus Xyliphius was established
by Eigenmann (1912) to include a single species, X. magdalenae
Eigenmann, from río Magdalena basin, Girardot, Colombia.
That description was based on a single specimen, 32.0 mm SL. Later,
four species were described in a short time frame: X.
lepturus and X. melanopterus from western
headwaters of río Bobonaza, upper Amazon basin (Orcés,
1962), X. barbatus (Alonso de Arámburu & Arámburu,
1962), and X. lombarderoi (Risso & Risso, 1964), from
río Paraná, in Argentina. A sixth species, X.
kryptos, was described by Taphorn & Lilyestrom (1983),
from río Aricuaisá, lago de Maracaibo basin, Venezuela.
Further collections, though small, expanded the distribution of
species of Xyliphius beyond their type localities (Cala,
1977). Currently, the six nominal species of Xyliphius
are known from northern South America in the río Magdalena
system (X. magdalenae), lago de Maracaibo (X. kryptos),
and western headwaters of the Amazonas basin and río Orinoco
(X. lepturus and X. melanopterus),
and from southern South America in the río de La Plata system
(X. barbatus and X. lombarderoi) (Taphorn &
Lilyestrom, 1983; Galvis et al., 1997; Calviño & Castello,
2008). Another new species, Xyliphius anachoretes (Figueiredo
Carlos A, Britto Marcelo R. 2010) making 7 species in total is from
the Tocantins-Araguaia River system.
