Etymology. The specific name is an adjective, referring to the broad copulatory ducts in the female epigyne.

Diagnosis. Echinax breviducta sp. nov. can be distinguished from E. panache by: 1) the short copulatory ducts (vs long in E. panache ) (cf. Fig. 2E View FIGURE 2 with Fig. 12E View FIGURE 12 ); 2) the short, slightly curved distal part of embolus (vs long and prominently curved in E. panache ) (cf. Figs 2A–C View FIGURE 2 , 13G–H View FIGURE 13 with Figs 12A–C View FIGURE 12 , 13C–D View FIGURE 13 ).
