tuckeri species group

Diagnosis. Lacking intermarginal denticles in chelicerae ( Figs 37e , 40e ); female epigyne with AMLL fused together and encircling MS entirely ( Figs 38a , 41a ); male palps with an enlarged sub-tegulum (not as large as those of jaegeri -group) and very long embolus tip, embolus much longer relative to tegulum compared to other species groups; EM developed and forming a process covering ET partially ( Figs 37a–c ) to completely ( Figs 40a–c ).

Species composition. Two species: E. tuckeri comb. nov., E. educatus spec. nov.

Distribution. South-west Africa: Namibia and Angola ( Fig. 71b ).
