Relevant Information:

Description: The new species has been long confused with Chaetostoma milesi, a species with similar overall morphology and colour pattern that is restricted to the Magdalena-Cauca River Basin. We diagnose the new species on the basis of morphology as well as a precise description of the colour pattern. Chaetostoma joropo is also easily distinguished from C. formosae the most similar species and other species inhabiting the Orinoco River drainage in Colombia. Data on ontogenetic variation and sexual dimorphism are provided, as well as natural history notes and remarks on the usage of the name Chaetostoma milesi for specimens from both the Orinoco and Magdalena-Cauca drainages. A discussion on the usage of the name Chaetostoma platyrhynchus is also provided given its current instability in the literature (Ballen et al.). Habitat: Chaetostoma joropo is described from the piedmont of the Orinoco River drainage in Colombia. Aquarium Care: As C. joropo is a more warm loving species it will need a good water flow in the aquarium with a sand substrate and plenty of hiding places. The Chaetostoma species are not the easiest to maintain as the mountain stream species will need a water current to provide oxygen-rich water. The species that are exported usually originate from warmer waters so are a bit easier to keep than the mountain stream variety. Diet: Great algae eater, but you will have to subsidise this food with algae wafers and vegetable foods such as cucumber, zucchini and lettuce. Will also except tablet and worm foods. Sexual Differences: Males have better colour, a broader head and lips and adult males possess longer ventral fins than the females. Etymology: The specific name joropo refers to a collection of musical styles in the Llanos, the Orinoco-basin - because Chaetostoma joropo lives there.

IUCN Red List

Chaetostoma joropo is assessed as Vulnerable. The species is restricted to piedmont and mountain rivers and the Meta and Guaviare drainages. Some of these rivers are well-preserved, however, the threats exist in many drainages associated with the expansion of the agricultural and urban frontiers, including deforestation, land-use change, sedimentation and urban effluents. There is continuing decline in habitat based on these threats. The area of occupancy (AOO) is best estimated at 1,580 km². There are 2–4 threat-based locations (IUCN 2021).
