Figs 25–28

Type material. Holotype: male from Caruaru , Pernambuco, Brazil, coordinates -8.266667, -35.966667, 2009– 2010, H.P. Amorim ( IBSP 160508). Paratypes: 1 female, same data as holotype ( IBSP 160509), and 1 male and 1 female, same data as holotype ( UFPE).

Additional material examined. BRAZIL: Pernambuco: 5 males, Caruaru, 2009 –2010, H.P. Amorim ( IBSP 160510 – 160513, UFPE).

Etymology. The specific epithet is a toponymic name in apposition.

Diagnosis. Males of this species differ from those of the other two by having the embolus curling almost two turns around the bulb, and having the sperm duct loop at the center of the distal region of the tegulum ( Fig. 25 ). Females can be distinguished from those of M. aracoiaba sp. nov. by the shorter copulation duct, best noticed at the posteriormost region, where the membranous portion becomes the sclerotized portion ( Fig. 28 ).

Description. Male holotype: Total length: 6.30. Carapace dark brown, glabrous, 3.05 long, 2.35 wide, 1.60 high. Ocular quadrangle 1.65 long. Anterior eye row 2.00 wide and posterior 1.90 wide. Chelicera, endite, labium and sternum dark brown. Palp dark brown. Legs I and II dark brown with yellow tarsi, III and IV with yellow coxae and trochanters, dark brown femora, light brown patellae and tibiae and yellow metatarsi and tarsi. Length of femur: I 2.30, II 1.85, III 2.20, IV 1.90; patella + tibia: I 3.40, II 2.30, III 2.35, IV 2.00; metatarsus + tarsus: I 2.20, II 1.55, III 1.85, IV 1.90. Abdomen light brown with white anterior border and a dorsal longitudinal lighter stripe; ventrally light brown. Spinnerets dark brown.

Female (paratype IBSP 160509): Total length: 6.40. Carapace dark brown, glabrous, 2.90 long, 2.17 wide, 1.40 high, with a light brown area around the ocular quadrangle. Ocular quadrangle 1.55 long. Anterior eye row 1.90 wide and posterior 1.85 wide. Chelicera, endite and labium dark brown, sternum light brown. Palp light brown. Legs I and II yellow, with distal portions of femora, patellae, tibiae and metatarsi dark brown, as well as the proximal portion of tibiae, III and IV yellow with distal portions of femora, patellae, tibiae and metatarsi dark brown, as well as the proximal portion of femora and tibiae. Length of femur: I 1.60, II 1.50, III 1.90, IV 1.70; patella + tibia: I 2.15, II 1.80, III 1.95, IV 1.85; metatarsus + tarsus: I 1.40, II 1.25, III 1.55, IV 1.75. Abdomen dorsally variegated with dark brown and pale yellow, anterior border white and a pair of longitudinal sinuous light lines that fuse at the middle and again twice in the posterior half of the abdomen, being completely fused posteriorly; ventrally light brown. Spinnerets dark brown.

Variation. Although the female paratype described has an elliptical atrium on the epigyne ( Fig. 27 ), the other female paratype has a posterior prolongation of the atrium similar to that of the paratype of M. aracoiaba sp. nov. ( Fig. 9 ).

Distribution. Known only from the State of Pernambuco, Brazil.

Biological note. The specimens mentioned above were collected from the ground using a pitfall trap.
