Armbruster, JW, NK Lujan & DC Taphorn, 2007. Four new Hypancistrus (Siluriformes: Loricariidae) from Amazonas, Venezuela. Copeia 2007: 62–79.
Abstract
Hypancistrus contradens, H. debilittera, H. furunculus, and H. lunaorum are described based on specimens from the upper RÃ*o Orinoco of southern Venezuela. Hypancistrus furunculus differs from other Hypancistrus based on color pattern: distinct dark oblique stripes ending at posterior insertion of dorsal fin and vertical bands in caudal fin (vs. oblique stripes ending at end of caudal fin in H. zebra and thin, indistinct, light-colored bands and vermiculations on a dark background in H. debilittera) and color pattern dark with white spots in H. contradens, H. inspector, and H. lunaorum. Hypancistrus contradens and H. lunaorum differ from H. inspector by having the dorsal fin reaching the adipose fin when adpressed (vs. not reaching), having spots on the head the same size as the body or spots absent (vs. spots smaller on head) and by usually having 22–23 mid-ventral plates (vs. 24); and from H. debilittera, H. furunculus, and H. zebra by lacking bars, saddles, or stripes on the body and bands in the fins. Hypancistrus lunaorum differs from H. contradens by having white spots on the body smaller than nasal aperture diameter (vs. white spots larger than the nasal aperture diameter).
Hypancistrus contradens = L201
Hypancistrus debilittera = L129
Hypancistrus furunculus = L199
Hypancistrus lunaorum = L339
