Taxonomy [top]

Kingdom	Phylum	Class	Order	Family
ANIMALIA	CHORDATA	ACTINOPTERYGII	SILURIFORMES	MOCHOKIDAE

Scientific Name:

Chiloglanis fasciatus

Species Authority:

Pellegrin, 1936

Common Name/s:

English

–

Okavango Suckermouth

Taxonomic Notes:

Chiloglanis fasciatus was described from a single specimen from the Cubango (=Okavango) River in Angola. At least four Chiloglanis species occur in the Upper Zambezi River system (Tweddle et al. 2004), but the taxonomy needs to be investigated before the other species can be fully recognised and added to this database. The species discussed here is that currently recognised under the name C. fasciatus in Skelton (2001). The distribution map may include specimens of the other species.

Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Assessed:	2007
Assessor/s:	Tweddle, D.
Reviewer/s:	Bills, R. (Freshwater Fish Red List Authority) & Darwall, W. (IUCN Freshwater Biodiversity Assessment Unit)
Justification: The species here recognized as C. fasciatus is widespread with no immediate threats to its habitat. This assessment is unlikely to change after taxonomic investigation.

Population [top]

Population:	Common in suitable habitats.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Skelton (2001) reports the species from rocky rapids and fringing vegetation in the mainstream current. In the Upper Zambezi, Tweddle et al. (2004) reported it from grounded vegetation mats in the main river channel, and along sandy cliff river banks when the river was overflowing onto the floodplain. Similarly, Tweddle et al. (2003) reported the species from over-topping banks of the Okavango River in the Panhandle area, while the species was not found in the delta region. In rocky southern rapids of the Upper Zambezi a more robust form was recognised that may be distinct, while in northern Zambezi tributaries at least two clearly distinct species were recognised (Tweddle et al. 2004). Feeds on small invertebrates and algae from the surface of rocks and plants.
Systems:	Freshwater

Systems:

Freshwater

Threats [top]

Major Threat(s):	Regulation of water flows are likely to have major impacts on all Chiloglanis species. Plans to develop dams and HEP schemes in the upper Okavango will thus threaten this species.

Conservation Actions [top]

Conservation Actions:	Plans to develop HEP and dam schmes need to consider all species that require seasonal and strong flows.
