Description of a new species of Acestridium (Siluriformes: Loricariidae) from Colombia
Zootaxa 972: 1-6
Abstract
Acestridium colombiensis is described from a single series of specimens from the Rio Inirida, Colombia. Acestridium colombiensis can be distinguished from its congeners by a unique combina-tion of characters: two unpaired median pre-dorsal plates, body width 10.0 -13.0% of post-dorsal fin length, inter-orbital distance between 10.6 - 13.0% of post-dorsal fin length, inter-orbital dis-tance between 25.0 - 29.0% of eye-to-dorsal fin length; low number of jaw teeth (12-15 teeth in upper left jaw, 9-13 teeth in lower left jar), pre-dorsal fin body pigmentation not formed into dis-tinct lines between longitudinal rows of odontodes.
