Species

There are currently 12 recognized species in this genus:[1][2]

Distribution and habitat

edit

The genus Sturisomatichthys is distributed in the northwestern part of South America, on the Pacific and Atlantic slopes of the Andes. The species appear to occupy the same ecological niche as those in Sturisoma.[4]

Description

edit

Sexual dimorphism and reproductive biology of Sturisomatichthys similar to Sturisoma. Sturisomatichthys is distinguished from Sturisoma primarily by the absence of a rostrum. Only one species, S. citurensis, from Panama, seems to be significantly different from all congeneric species in having an abdominal plate cover consisting of small platelets without any particular organization. Other species may represent a species complex with a short snout as in the genus Farlowella with reference to the representatives of the F. curtirostra group. The weakness of this diagnostic feature could lead to the synonymy of Sturisomatichthys with Sturisoma.[4] Sturisomatichthys species grow to about 18–25 centimetres (7.1–9.8 inches) in length.[1]
