Pseudomastax nigroplagiata Descamps 1970: 617 , 630-632; 1973b: 958; 1979: 138, 140, 141; Olivier 2017: 236, 238, 239.

Type locality. Peru: Pasco Department: Oxapampa .

Depository. Muséum national d’Histoire naturalle—Paris, France.

Examined material. 1 male—Brasil, Acre, Rio Branco, 25.X a 8.XI.91, F. Ramos, A. Henriques, I. Gorayeb, N. Bittencourt \ Mata. Armadilha suspensa 20 m. T. [terra] firme \ 197 \ Pseudomastax nigroplagiata Descamps, 1970 R. Olivier det. (2015) (MPEG).

Distribution. BOLIVIA: Beni Department; BRAZIL: State of Acre; PERU: Pasco Department, Cuzco Department, Lima Department, Junín Department, Loreto Department, Madre de Dios Department ( Fig. 3 ).

Remarks. Morphology: The male color pattern of this species is very similar to that of P. graciollii sp. nov., as shown in Figure 4A , but differs by the shape of male cerci and phallic complex (in P. nigroplagiata the phallic complex is similar to that of P. pictifrons (pers. obs.); see Descamps (1970), page 632, Fig. 59). This is the first record of this species for Brazil ( Fig. 3 ) and the first record of a Eumastacidae for Acre State. The examined specimen is more similar to the morphotype occurring in Bolivia, according to information provided in Descamps (1979), that presents two black marks at the level of the sub-antennal transverse sutures ( Fig. 4B ). The measurements of the studied specimen are shown in Table 2.
