Furcodontichthys Rapp Py-Daniel, 1981 ^ZBK.

Type species: Furcodontichthys novaesi Rapp Py-Daniel, 1981 ^ZBK.

Holotype: INPA T.79-014, Brazil, State of Amazonas, Rio Solimoes, Tefe Lake at Caititu .

Gender: masculine.

This monotypic genus is known from the middle Amazon at Lake Tefé and from the upper Jurua River drainage in the Solimões River basin. Furcodontichthys ^ZBK inhabits sandy substrates. Evers & Seidel (2005) captured Furcodontichthys novaesi ^ZBK at night, on a sand bank, in black waters of the Rio Tefé . As with representatives of the Loricariichthys ^ZBK group, males of Furcodontichthys ^ZBK show a hypertrophied development of the lips suggesting that this genus is a lip brooder. The presence of conspicuous fringed barbels at the lip corners is unique among the Loricariinae . These barbels have branching patterns comparable to those of the Pseudohemiodon ^ZBK group.
