is one of two genera found within the family Chimaeridae. Species in this family are typically characterized as having short fleshy snouts that are bluntly pointed at the tip, elongate bodies tapering to a whiplike tail with an elongate filament, and are uniform brown, gray, or black in color with the possibility of white spots or stripes (Didier, 2004). There is very little difference between

The holotype (Figure 1), which was thought to be lost due to a tsunami that partially destroyed the museum it was previously contained in, was rediscovered and it is now part of the collection at the Museo Nacional de Historia Natural in Santiago, Chile (MNHNC P. 7282).
