Comments: Type locality of the holotype of Pseudobarbus skeltoni: 'at the pool-riffle interphase at the foot bridge just below gauging weir in the Riviersonderend River upstream of Theewaterskloof Dam, Breede River system, at altitude 327m' (Ref. 93872). Known from upper Riviersonderend, Krom River and Wit River, all part of Breede River system (Ref. 93872). But Pseudobarbus skeltoni has not been collected from the Wit River in surveys after 1980 and this river has now been invaded by the aliens Clarias gariepinus and Micropterus dolomieu, which suggests that this population may have possibly been extirpated (Ref. 93872).

Etymology: Pseudobarbus: Greek, pseudes = false + Latin, barbus = barbel (Ref. 45335); skeltoni: The specific name, skeltoni, is given in honour of Professor Paul H. Skelton in recognition of his lifelong service to taxonomic and systematic research on freshwater fishes in southern Africa, his contribution to the taxonomic revision and systematics of Pseudobarbus and specifically for his mentoring of students on this group of fishes (Ref. 93872).

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 10-12; Épines anales 0; Rayons mous anaux: 8; Vertèbres: 36 - 38. Diagnosis: Pseudobarbus skeltoni reaches the largest size of any Pseudobarbus species and is distinguished from its congeners, except P. burchelli and P. burgi, by possessing two pairs of prominent oral barbels (Ref. 93872). It is distinguished from P. burchelli and P. burgi by the combination of the following features: distinctive terminal mouth in adults vs. subterminal in all size classes of P. burchelli and P. burgi; juveniles, sub-adults and young adults of P. skeltoni have subterminal mouths, but their lower lips are unretracted and they lack the cartilaginous plate found in both P. burchelli and P. burgi; a typically longer head relative to standard length, being 30.5% vs. 26.8% in P. burchelli and 25.8% in P. burgi; shaloow head depth, being 64.2% of head length compared to 70.1% of head length in P. burchelli and 74.1% of head length in P. burgi; mature sexually active males develop two clusters of large conical tubercles on the snout, with 22-30 tubercles in each cluster, vs. 5-10 tubercles per cluster in P. burchelli and 10-15 tubercles per cluster in P. burgi; multiple rows of large conspicious tubercles above each nare and antero-dorsal edge of each orbit, vs. single row in congenres (Ref. 93872).

Reproduction is unknown, but spawning possibly occurs around November-December, based on the observation that males had large tubercles; juveniles and sub-adults probably feed by picking prey or algae from rock; adults have more predatory lifestyle and are possibly water column feeders (Ref. 93872).
