Etymology. The specific name refers to a tipical dish from the State of Minas Gerais, tutu à mineira.

Diagnosis. Males of Actinopus tutu   resemble those of A. longipalpis   ( Fig. 156 View FIGURE 156 A–C), A. azaghal   ( Fig. 148 View FIGURE 148 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. pindapoy   ( Fig. 159 View FIGURE 159 A–C) and A. azaghal   by PA continuous to PI. They resemble those of A. azaghal   by a small-serrated area present only in the proximal part of embolus. They differ from those of A. itacolomi   by the thinner embolus and absence of a tegular swelling above PA. Females of A. tutu   resemble those of other species of Actinopus   , as A. trinotatus   ( Fig. 220 A View FIGURE 220 ), A. wallacei   ( Fig. 225 A View FIGURE 225 ) and A. pampulha   ( Fig. 49 D View FIGURE 49 ) by the presence of two receptacles, with two or three lobes. They differ from those of A. pampulha   and A. wallacei   by the presence of lateral swelling on each receptacle and from A. pampulha   and A. trinotatus   by a pore distribution that reaches 75% on each receptacle.
