Fig. 5. Detailed photographs of the spinous portion of the dorsal fin of species of Bujurquina Kullander, 1986 in the Northern group (see Figs 1 and 4). Note two main types of patterning of the dorsal fin, a blotched patterning vs lines in the spinous portion of the dorsal fin. Note additional differences in patterning of the spinous portion of the dorsal fin between the species, such as different numbers of lines per membrane, their thickness or angle. Also note differences in the coloration of the dorsal fin lappets between some of the species.
