A new species catfish, Amphilius pagei (Siluriformes: Amphiliidae) from Angola
Thomson, Alfred W., Swartz, Ernst R. (2018): A new species catfish, Amphilius pagei (Siluriformes: Amphiliidae) from Angola. Zootaxa 4420 (2): 292-300, DOI: 10.11646/zootaxa.4420.2.1
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.Published as part of <i>Chakona, Albert & Swartz, Ernst R., 2013, A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa, pp. 565-577 in Zootaxa 3686 (5)</i> on page 568, DOI: 10.11646/zootaxa.3686.5.5, <a href="http://zenodo.org/record/10098673">http://zenodo.org/record/10098673</a>

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).Published as part of <i>Chakona, Albert & Swartz, Ernst R., 2013, A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa, pp. 565-577 in Zootaxa 3686 (5)</i> on page 569, DOI: 10.11646/zootaxa.3686.5.5, <a href="http://zenodo.org/record/10098673">http://zenodo.org/record/10098673</a>
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).Published as part of <i>Chakona, Albert & Swartz, Ernst R., 2013, A new redfin species, Pseudobarbus skeltoni (Cyprinidae, Teleostei), from the Cape Floristic Region, South Africa, pp. 565-577 in Zootaxa 3686 (5)</i> on page 573, DOI: 10.11646/zootaxa.3686.5.5, <a href="http://zenodo.org/record/10098673">http://zenodo.org/record/10098673</a>
