Citharidium ansorgii is a species of lutefish found in the Niger River basin in Nigeria. They reportedly may also be found in Cameroon. It is the only member of its genus. Its conservation status is of the least concern. The only known threats which could negatively affect the population of this species are oil studies in the Lower Delta and potential impact of the invasive water hyacinth in the inland delta.[1]
