Attributs

DISTRIBUTION: Lien Faunafri
Colour pattern : Chakona & Swartz, 2013 .
Common names : Giant redfin (English), Skeltoni punapardlik (Estonian) .
Current distribution known : collected from only two localities, one in the upper Riviersonderend River (a major tributary of the Breede River) and another in the Krom River (a tributary of the Molenaars River), in the Breede River system. Some specimens from the Wit River (Bainskloof) and deposited in the Albany Museum as P. burchelli are morphologically concordant with this P. skeltoni. P. skeltoni has not been collected from the Wit River in recent surveys, suggesting that this population may have possibly been extirpated, because the river section where the specimens were originally collected in 1975 has now been invaded by alien fish predators .
