Figs 34–36 , 45

Holotype: male from Presidente Figueiredo (Hidrelétrica de Balbina , Reserva Biólogica do Uatumã, Ilha Cachoeira, 1.862306°S 59.367306°W), 16.VII.2006, A.L. Tourinho ( INPA 0873). Paratypes: one female with the same data as holotype ( INPA 865); one male with same data, except for Ilha Santa Luzia (1.734194°S 59.4415°W), 21.VII.2006, R. Saturnino (ex-INPA 866 = MPEG 21096).

Etymology. The epithet is a toponymy in apposition and refers to the place from where type specimens were collected.

Diagnosis. This species is similar to M. similis sp. nov. and M. delicatus sp. nov. by having a median projection only on the prolateral side of the embolus. From M. similis sp. nov., it differs by the embolus tip, which is more straight and slender, and from M. delicatus sp. nov., this species differs by having a longer embolus, with the thinner tip being as long as the embolus base ( Fig. 34 ). Females of this species are very similar to those of M. delicatus sp. nov., with smaller copulation openings ( Figs 32–33, 35–36 ), but it is difficult to tell them apart. So far, the two species have not been found living at the same locality.

Description. Male (holotype). Total length: 5.98. Carapace 3.04 long, 2.18 wide and 1.71 high. Length of ocular quadrangle: 1.61; anterior eye row 2.09 wide, posterior 1.90 wide. Legs 1342. Length of femur I: 2.18; II: 1.71; III: 2.28; IV: 1.99; patella+tibia I: 2.94; II: 2.37; III: 2.37; IV: 2.09; metatarsus+tarsus I: 1.99; II: 1.52; III: 1.99; IV: 2.18.

Female (paratype INPA 865). Total length: 7.12. Carapace 3.42 long, 2.47 wide and 1.71 high. Length of ocular quadrangle: 1.90; anterior eye row 2.28 wide, posterior 2.09 wide. Legs 3412. Length of femur I: 1.90; II: 1.80; III: 2.56; IV: 2.28; patella+tibia I: 2.56; II: 2.18; III: 2.56; IV: 2.28; metatarsus+tarsus I: 1.61; II: 1.42; III: 1.99; IV: 2.18.
