FIGURE 7 in A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa
FIGURE 7. Pictures showing localities and habitat where specimens of Pseudobarbus skeltoni were collected: (A) upper Riviersonderend (note the foot bridge of hiking trail crossing the river just below the gauging weir), and (B) Krom River.
FIGURE 6 in A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa
FIGURE 6. Map of the Breede River system in the south-western Cape Floristic Region of South Africa showing the distribution of Pseudobarbus skeltoni sp. nov. Individuals of this species were previously collected from the Wit River in 1975, but have not been found in recent surveys. The upper Riviersonderend is the type locality.
FIGURE 4 in A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa
FIGURE 4. Lateral view of the heads of (a) P. skeltoni sp. nov. (holotype, SAIAB 187243, 158.2 mm SL), (b) P. burchelli (neotype, SAIAB 126387, 95.9 mm SL) and (c) P. burgi (PG2076, 93.5 mm SL). Note the position of mouth, and a large eye relative to head length in P. burchelli and P. burgi. Also note the clear differences in tubercle expression of mature males of the three species.
FIGURE 5 in A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa
FIGURE 5. Ventral view showing the difference in the mouth forms of (A) P. burchelli (specimen from RUSI 058390), (B) P. burgi (specimen from SAIAB 186124) and (C) P. skeltoni sp. nov. subadult (specimen from SAIAB 187241). Both P. burgi and P. burchelli have retracted lips exposing a cartilaginous plate, but lips are unretracted in P. skeltoni and cartilaginous plate is absent (based on seven specimens examined).

FIGURE 2 in A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa
FIGURE 2. Scatter plot of PCI against PCII for a PCA carried out on 14 normalised morphometric and seven raw meristic characters for all examined specimens (n = 245). The cluster of P. skeltoni sp. nov include 12 recently collected specimens from the Riviersonderend and Krom Rivers as well as 11 specimens from two samples collected in the Wit River (see text for details).
FIGURE 1 in A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa
FIGURE 1. Bayesian phylogram with Bayesian posterior probabilities, showing the genetic distance between Pseudobarbus skeltoni sp. nov. compared to all other Pseudobarbus lineages. Although phylogenetic relationships among Pseudobarbus lineages should be based on Swartz et al. (2009) due to more data that were analysed, it is clear from the present study that P. skeltoni is closely related to Pseudobarbus lineages that have two distinct pairs of barbels. More genes will have to be analysed to resolve the phylogenetic relationships within this group.

Figure 5 - Live colours of Pseudobarbus afer s.s (SAIAB 203790) from the Waterkloof River, Swartkops River system, Pseudobarbus senticeps (RS17AL01) from the source pool in the Upper Krom River system and Pseudobarbus swartzi sp. n.

Figure 3 from: Chakona A, Skelton PH (2017) A review of the Pseudobarbus afer (Peters, 1864) species complex (Teleostei, Cyprinidae) in the eastern Cape Fold Ecoregion of South Africa. ZooKeys 657: 109-140. https://doi.org/10.3897/zookeys.657.11076
Figure 3 - a Scatter plot of PC1 against PC2 for a PCA carried out on five raw meristic characters (scale counts) for 162 specimens of the Pseudobarbus afer complex b Scatter plot of PC1 against PC2 for a PCA carried out on 17 morphometric characters for 154 specimens of the Pseudobarbus afer complex. Syntypes were not included in the analyses as all three specimens are in very poor condition, with very few intact scales, flaccid bodies and damaged fins. The plots indicate that Pseudobarbus senticeps, Pseudobarbus afer s.s. and Pseudobarbus swartzi can be clearly separated based on scale counts, but the three species show considerable overlap in morphological characters.

Figure 6 - Preserved colours of Pseudobarbus afer s.s topotype (SAIAB 203790) from the Waterkloof River, Swartkops River system, Pseudobarbus senticeps holotype (SAIAB 304) from the Assegaaibosch River, Krom River system, Pseudobarbus senticeps topotype (SAIAB 200302) from the Assegaaibosch River, Krom River system, and Pseudobarbus swartzi sp. n. holotype (SAIAB 203792) from a tributary of the Wabooms River, Gamtoos River system. Note the differences in the arrangement of melanophores which produces distinct patterns on the latero-ventral scales of the three species.
