Diagnosis. The female of A. longipalpis  differs from those of all other species in Uruguay by the shape of their spermathecae ( Fig. 5DView FIGURE 5) being wide basally, with a well truncated fundus, concave dorsally with external lobes projected perpendicular to the duct (similar to A. argenteus  ; A. casuhati  and A. gerschiapelliarum  from Argentina). Females differ from those of A. argenteus  and A. casuhati  by the smaller number of retrolateral spines on tibia II ( Fig. 5CView FIGURE 5) and from A. gerschiapelliarum  by the form and shape of their spermathecae. Males can be differentiated from all other species by the thick copulatory bulb thick, with the embolus arising apically ( Fig. 4View FIGURE 4 G–I); and a low number of retrolateral spines on tibia II ( Fig. 4FView FIGURE 4), and from those of A. pampa  and A. argenteus  by the abdomen with a brown dorsum.

Description. See Ríos-Tamayo & Goloboff 2018, figs 23A–I, 24A–D.

Distribution: Northern Uruguay and northern of Argentina (Entre Ríos province), ( Fig.10View FIGURE 10). The type locality “Montevideo” seems be just the default shipping port (see Ríos-Tamayo & Goloboff 2018, p. 52).
