Material examined: Holotype 3, Sichuan Prov., Gonggashan, 2400m, 5 November 1999, coll. Dworakowska; Paratype: 3Ƥ, Sichuan Prov., Gonggashan, 2400 m, 5 November 1999, coll. Dworakowska; 1Ƥ, Sichuan Prov., Moxi, 2000 m, 5 November 1999, coll. Dworakowska.

Remarks: The new species resembles E. rudobreva (Dworakowska 1993: 152, 153, 165) but differs in its extension at the hind upper angle of the pygofer and long sclerotized appendage, and by the longer apical penis appendages and bigger apodeme.

The specific epithet is derived from the Latin words “ eury- ” and “ projectus ”, referring to the broad end of the apical penis appendages.
