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 A–C), A. azaghal (Fig. 148 A–C) and A. itacolomi (Fig. 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 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), A. wallacei (Fig. 225 A) and A. pampulha (Fig. 49 D) 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.
