Male holotype (MUSM-Ent 504411) and male paratype (MUSM-Ent 511659) from Peru , Amazonas , Nueva Esperanza , Rodriguez de Mendoza Province , 6°24'27.5"S 77°27'31.4"W , 1493 m , 1.XII.2004 , W. Paredes leg. Etymology. The specific name is a patronym in honour of arachnologist Williams Paredes, collector of the types . Diagnosis. Males of E. paredesi n. sp. resemble those of E. abiseo by the embolar base fused to the tegulum ( Figs 1 , 3; Bonaldo, 1994 : figs 35¯37), but differ by the longer, filiform embolus and by the RTA excavated ( Figs 1 , 2). They also resemble those of E. madre Bonaldo by the wide, retrolaterally directed median prong of the MA ( Fig. 23 ), but are readily recognized by the embolus not articulated, without processes.
