Materials Examined
Type:Holotype male and paratype female, La Azulita [7 º 16 ’ 18 ”N, 71 º 56 ’ 25 ”W] Apure, Venezuela; 26 September 2002, Dirk Weinmann, FCE–MY.
Etymology
Etymology: The specific epithet is a patronym in honor of Dirk Weinmann, arachnologist and collector of the type specimens.
Diagnosis
Diagnosis: The male differs from those of other species of Ami in the very reduced number of cuspules on labium (4). The females differ from those of most species of Ami in the morphology of the spermathecae with two basal plates and without modified receptacles and from A. pijaos in the presence of a single large striated receptacle (Fig. 36) which additionally differs from other species of Ami in the presence of very short sub-triangular tarsi with a particular longitudinal rhomboid scopulae division (43–44). This species is closely related to A. pijaos (see Cladistics).
