Key to the species of Dingosa

1. Dark cardiac mark on opisthosoma strongly serrated, first anterior serration forms a distinct angle of ca 45 ° with body axis ( Figure 1A, B, G, H ); tegular apophysis of male pedipalp without basal tooth ( Figures 2C , 6A ); female epigyne with continuous anterior margin ( Figure 2E ) or much longer than wide ( Figure 6C ). 2

– Dark cardiac mark on opisthosoma weakly serrated, with two flat, tooth-like shapes on either side ( Figure 1C–F ); tegular apophysis of male pedipalp with basal tooth ( Figures 3A , 5A ); lateral edges of transverse part of median septum extend anteriorly ( Figures 3C , 5C )................ 3

2. Tip of tegular apophysis of male pedipalp curled ventrally ( Figure 2D ); epigyne wider than long and with continuous anterior margin ( Figure 2E ).. D. simsoni

– Tip of tegular apophysis blunt, distinctly keeled in ventral view ( Figure 6A ); female epigyne longer than wide and anterior margin not continuous ( Figure 6C ).. D. serrata

3. Tip of tegular apophysis of male pedipalp distinctly curved ventrally ( Figure 3B ); lateral edges of transverse part of median septum in female epigyne reaching under the anterior pockets ( Figure 3C )........... D. humphreysi

– Tip of tegular apophysis of male pedipalp more or less straight ( Figure 5B ); lateral edges of transverse part of median septum in female epigyne truncated ( Figure 5C )................ D. murata n. sp.
