Modally 8 anal-fin rays; 29 or more predorsal circumferential scales; absence of basicaudal spot; breast fully scaled; upper jaw large, length greater than 9.4% SL, extending under orbit; gular stripe reaching under orbit, not to isthmus; breeding males with many large tubercles over head, with narrow gap on rostrum, not organized into rows, less than 16 non-marginal tubercles on caudal-peduncle scales; both breeding males and females with distinct plum-colored lateral stripe below iridescent light-yellow stole; and scapular bar absent or weak; mouth terminal to subterminal (Ref. 42680).
