Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); sainthousei: The specific name honours Ian Sainthouse, renowned breeder and collector of killifish, for his special longstanding dedication to researches on the genus Nothobranchius; a noun in genitive (Ref. 116789).
Eponymy: Ian Sainthouse is a British aquarist and killifish enthusiast. He was honoured as a: “… renowned breeder and collector of killifish” and for “…his special longstanding dedication to researches on the genus Nothobranchius”. (Ref. 128868), visit book page.

Diagnosis: Nothobranchius sainthousei is distinguished from the other Nothobranchius species from the drainages of the Upper Congo in northern Zambia and Katanga province of DRC, except N. rosenstocki, by having broad orange-brown posterior scale margins on the trunk, vs. red, and an anal fin with orange-brown margin, vs. light blue or yellow or red-brown or black (Ref. 116789). It is distinguished from N. rosenstocki by having dorsal and anal fins with orange-brown spots, vs. irregular orange-brown bars; furthermore, N. sainthousei is distinguished from all members of the N. brieni group by head length, 25.1-29.3% of standard length vs. 29.6-38.7%, and head width, 71-79% of head length vs. 52-62% (Ref. 116789).
Body shape (shape guide): fusiform / normal.
Body shape (shape guide): fusiform / normal.
Found in ephemeral habitats in the floodplain between the small seasonal Chimbembe and Kusake rivers; about 5 km southwest of the confluence of the Luapula with the Luongo (Ref. 116789). The ephemeral pools were about 5-10 m wide, and less than 1 m deep at the deepest point; the aquatic habitat was heavily overgrown with grass (Ref. 116789). The water of pH 6.98 contained 15 ppm of total dissolved solids; it was brown and turbid, so the pool substratum was only visible at shallower depths; the water temperature measured at midday was 23.0°C (Ref. 116789). The conservation status of Nothobranchius sainthousei is uncertain, but appears to qualify as vulnerable (Ref. 116789). Stomach contents of adult wild-caught specimens show that N. sainthousei is a micropredator, feeding on small aquatic crustaceans, worms, insect larvae and other zooplankton (Ref. 116789).
