Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); angelae: The specific name is given in honour of Angela Watters, wife of Brian R. Watters, in recognition of her unwavering support for his many field trips to Africa to study fishes of the genus Nothobranchius, during which she also very capably maintained the fishes in the tanks of his large fish room; a noun in genitive (Ref. 122068).
Eponymy: Angela Watters is the wife of the first author, Brian Watters (q.v.), who honoured her for ‘unwavering support’ for his many field trips to Africa to study killifish. (Also see Watters) (Ref. 128868), visit book page.

Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 15 - 16; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 16 - 18. Diagnosis: Nothobranchius angelae is distinguished from all other species of the genus by the following combination of characters in males: body colouration light blue to blue-green with red-brown or dark grey scale margins; anal fin light blue-grey to yellow-grey with irreguar brown spots, with narrow brown submedial band, slender white to pale cream medial band and broad black distal band; caudal fin light brown-grey with irregular dark brown spots proximally, followed by a narrow dark brown medial band, a slender white subdistal band and a slender to broad black distal band; pelvic fins light blue-grey to blue-green, with broad white to cream medial band and narrow black distal band (Ref. 122068). Furthermore, it differs from the other members of the Nothobranchius taeniopygus species group in central and western Tanzania by a postorbital length 55-63% of head length vs. 43-54%; and caudal peduncle length 132-137% of its depth vs. 119-130% and 140-169% (Ref. 122068).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Found in seasonal pools and marshes (Ref. 122068).
