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.

). Tibia IV without spines on dorsal surface with two visible rows of filiforms trichobothria (
