Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Cyprinodontiformes (Rivulines, killifishes and live bearers) > Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335);  albertinensis: The specific name, albertinensis, is given in reference to the Albertine Rift, in which valley the species is found in the northern Lake Albert basin and extending into the Albert Nile drainage; an adjective derived from the geographical name (Ref. 123150).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic; pH range: 7.8 - 8.5. Tropical; 29°C - 34°C (Ref. 123150)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 15-18; Anal spines: 0; Anal soft rays: 16 - 18. Diagnosis: Nothobranchius albertinensis is distinguished from all other species of the genus, with the exception of N. ugandensis, by the following combination of characters in males: body colouration light blue with red-brown scale margins; frontal part of head and snout red-brown and throat light blue; caudal fin uniform red (Ref. 123150). Furthermore, it differs from N. ugandensis by a yellow dorsal fin with red-brown stripes in medial part parallel to fin rays vs. light blue with red-brown spots and irregular stripes perpendicular to fin rays; yellow anal fin without markings vs. light blue and occasionally with red-brown spots; anal fin positioned anterior to dorsal fin, mean preanal length 59.8% of standard length and mean predorsal length 60.7% of standard length vs. posteriorly positioned with 60.9% of standard length and 60.2% respectively in N. ugandensis; and greater anal-fin base length, 22.5-25.9% of standard length vs. 19.3-22.2% (Ref. 123150).

Biology     Glossary (e.g. epibenthic)

Found in ephemeral pools and marshes as well as small river systems (Ref. 123150); the type locality is an isolated pool, about 1 m at the deepest point, in an area that was overgrown by reeds (Ref. 123150).
