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 with Fig. 12E); 2) the short, slightly curved distal part of embolus (vs long and prominently curved in E. panache) (cf. Figs 2A–C, 13G–H with Figs 12A–C, 13C–D).
