Characidae - Eretmobrycon brevirostris (Gunther, 1859)



SOURCE FOR OCCURRENCE IN ECUADOR: This species is very common along the western slope of southern Ecuador. There are many references for its occurrence in the area (e.g., Eigenmann, 1922; Eigenmann, 1929; Böhlke, 1958; Ovchynnyk, 1971; Gery, 1977; Glodek, 1978; Laaz et al, 2009; Laaz & Torres, 2010; Jimenez et al., 2015).
ORIGINAL DESCRIPTION: Günther, A. 1860. Second list of cold-blooded vertebrata collected by Mr. Fraser in the Andes of western Ecuador. Proceedings of the General Meetings for Scientific Business of the Zoological Society of London 1859(pt 3):402-420.
TYPE SPECIMENS:
TAXONOMIC STATUS: Valid (Eschmeyer and Fricke, 2011) although a comprehensive survey of the tetras in western Ecuador is necessary. This species was known until recently as Bryconamericus brevirostris. Thomaz et al. (2015) moved it to the genus Eretmobrycon.
RANGE ECUADOR: Esmeraldas and Guayas basins of western Ecuador (Glodek, 1978).
RANGE OUTSIDE OF ECUADOR: Northern Peru (Glodek, 1978).
COLLECTIONS IN ECUADOR:
MAXIMUM SIZE: 12 cm (Laaz et al, 2009).
DISTINGUISHING FEATURES: Eretmobrycon brevirostris differs from other characids by the combination of the following characters: body compressed, anal fin rays counts 34-39, lateral line scale counts 43-50, two obscure humeral spots formed by the absence of many chromatophores over the 7th-8th scales of the lateral line, middle caudal rays conspicuously black (Eigenmann, 1929).
ECOLOGY: This species is known in Ecuador as the “cazuela” or "cachuela". It is an omnivorous characid (Laaz et al, 2009).
ECONOMIC IMPORTANCE: This species is not exploited as a food fish because of its small size.
CONSERVATION STATUS: NA, although the species is not directly exploited as a food fish and appears to be common in the area.
