簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 15-18; 臀棘 0; 臀鰭軟條: 18 - 19. Diagnosis: Nothobranchius sonjae is distinguished from all other species of the genus by the following characters in males: body colouration light blue to blue-green with red-brown, brown or grey scale margins and a golden-brown to grey stripe on the dorsal scale row between nape and dorsal-fin origin; anal fin light blue-grey to yellow-grey with irregular red to red-brown spots proximally, followed by a narrow brown submedial band, a slender yellow medial band and a broad black distal band; caudal fin yellow-brown, grey-brown, blue-grey or grey, with red-brown, brown, dark grey or red spots; some populations with radiating red stripes, the density of which varies from moderate to highly dense such that in the latter cases the basal, proximal and medial zones may appear dominantly a deep red; distal zone comprises a slender to broad semi-translucent dark grey to black distal band; pelvic fin light blue-grey to yellow-grey, with broad yellow medial band and narrow black and blue distal margin (Ref. 122068). Furthermore, it differs from the other members of the Nothobranchius taeniopygus group in central and western Tanzania by a head length of 25.8-27.0% of standard length vs. 27.3-34.6%; and caudal peduncle length 153-159% of its depth vs. 119-149% and 160-169%, respectively (Ref. 122068).
Found in seasonal pools and marshes (Ref. 122068).
