6' SSt narrower and longer, about one ring. Base bare on concave side, spine band on convex side widening gradually, rarely an indistinct angle. The completely scaly distal part of the RC equals 1/3 of total length (e.g., Fig. 124 ). Vagina calyx-shaped, with sinuous lateral rods................................................................. 24 N. panafricana n. sp.

IV.1 The N. africana -complex (= clades D, E)

Clade D

The monophyly of this small lineage with only three species is only moderately well supported (73.9/98/0) in the DNA sequence data analyses, which is in line with only COX1 DNA barcode sequences being available ( Figs. 492–493 ).

Figures

FIGURE 492. Simplified overview of codon-model maximum likelihood phylogram based on 356 mitochondrial genome and COX1 DNA barcode sequences (all-NT). Terminal labels include information on the species only. Clades of particular interest highlighted with colours that correspond to the clades in other trees. The full tree is shown in Figs 493-498.

FIGURE 493. Partial (outgroup, clades A, B, D) codon-model maximum likelihood phylogram based on 356 mitochondrial genome and COX1 DNA barcode sequences (all-NT). Statistical support values above branches or near nodes are SH-aLRT and UFBoot for the codon-model analyses, followed by NT123 UFBoot. Terminal labels include information on the species, type status, gender, originating country, unique sequence identifier (NEOP###), sequencing approach and total basepairs of 13 mitochondrial, protein-coding genes. Clades of particular interest highlighted with colours that correspond to the clades in other trees. See Fig. 492 for an overview. HT = holotype; PT = paratype; PCR = Polymerase Chaine Reaction; WGS = Whole Genome Shotgun.
