Haplochromis ushindi Oijen, 2004

 

 

Taxonomy & Nomenclature

Synonym/s: Haplochromis "sharpsnout" van Oijen, 1982

 

Conservation Status

Last record: 1985

IUCN RedList status: Critically Endangered (Possibly Extinct)

 

Oijen (2004) states that all known specimens were collected between 1975 and 1985. However in the "material" section of the paper (Ibid.: 250) only lists specimens captured in 1980 or prior. It is assumed that specimens were collected up until 1985, but Oijen decided to utilize specimens which, whether by coincidence or intentional, were collected prior to 1981 when writing the paper.

 

Distribution

Mwanza Gulf, Lake Victoria, East Africa

 

Biology & Ecology

The largest piscivorous cichlid in the Mwanza Gulf area of Lake Victoria, males have been recorded up to 26cm TL.

 

Hypodigm

Haplochromis ushindi is known by "less than 100 specimens" in the RMNH collection (Oijen, 2004: 249), but exactly how many less is not known to the author of this database. Perhaps those specimens listed in (Oijen, 2004) comprise the total hypodigm of the species.
