Etymology. Refers to Azaghal (as know as Deive Pazos), producer of a podcast called “Nerdcast”, a Brazilian humorist that provide many hours of laughts, essential for the proper development of this work.

Diagnosis. Males of Actinopus azaghal resemble those of A. longipalpis ( Fig. 156 View FIGURE 156 A–C), A. tutu ( Fig. 143 View FIGURE 143 A–C), A. pindapoy ( Fig. 159 View FIGURE 159 A–C) and A. itacolomi ( Fig. 153 View FIGURE 153 A–C) by the presence of three keels in prolateral view of embolus, small total length, and inconspicuous patterns of coloration on legs and palp, when present. They resemble those of A. tutu by PA continuous to PAc and a small serrated area only on proximal part of embolus. They differ from those of those of A. itacolomi by the thinner embolus and swelling above PA absent. A. azaghal is very similar to A. tutu , but differs by BTA dorsally displaced in the prolateral tegulum and more pronounced PA. Also differ from A. argenteus ( Ríos-Tamayo & Goloboff, 2018, fig. 10 G–I) by BTA dorsally displaced, and PS reaching less than half of width of embolus.
