Type material. Holotype: male, BRAZIL: São Paulo: São Paulo, 2008, coll. G. Ruiz (UBC-SEM AR00158, IBSP #96121).

Etymology. Latin adjective dorsalis (dorsal), and refers to the dorsal apophysis on tibia of male palp.

Diagnosis. Differs from other Maeota species by the presence of a dorsal tibial apophysis of the male palp ( Figs 94–95 ). This species can also be distinguished from Maeota flava by the marking on the dorsum of the male abdomen ( Fig. 92 ); the shape of the embolic disc and the longer retrolateral tibial apophysis of the male palp ( Figs 93–94 ).

Description. Male (holotype, UBC-SEM AR00158). Carapace length 1.4; abdomen length 1.3. Chelicera: gray brown. Palp ( Figs 93–95 ): brown to yellowish, with gray pigment. Proximal tegular lobe large; retrolateral sperm duct loop very narrow; embolus relatively short and slightly coiled; retrolateral tibial apophysis finger-like; dorsal tibial apophysis present and slightly curved distally; ventral tibial bump present. Measurements of legs: I 2.6, II 2.5, III 3.0, IV 3.4. Color in alcohol ( Fig. 92 ): carapace dark brown and yellow brown around fovea region, with a narrow medial stripe behind fovea and two lateral stripes composed of white scales; abdomen gray brown with many brownish speckles, and a wide sandy yellow stripe medially, ventral abdomen and legs sandy yellow without distinct markings.

Female. Unknown.
