Thereza Roewer  

Emended description. Sexual dimorphism on shape of dorsal scutum absent (unknown in T. murutinga   sp. nov.). Maximal width of dorsal scutum reaching middle of area III. Prosoma as wide as opisthosoma (except T. murutinga   sp. nov., prosoma much narrower than opisthosoma). Areas II –III divided by a longitudinal median groove (except T. murutinga   sp. nov., II undivided and III with incomplete longitudinal median groove). Male spines of area III large. Pedipalpal prolateral subapical seta on femur absent. Leg IV smooth. Coxa IV visible only on apical region (in dorsal view), with tubercle-like apical apophyses. Basitarsus I normal. Distitarsus II four-segmented. Penis: ventral process with basal lateral projections and lance-shaped apex; ventral plate thin or thick, densely or weakly covered with short hairs ventrally; apical setae of ventral plate apically or subapically placed.

Emended diagnosis. Thereza   roughly resembles Garatiba Mello-Leitão   by the longitudinal median groove on areas II (except T. murutinga   ) and III (complete in Garatiba   and Thereza   , incomplete in T. murutinga   and absent in other caelopyginean genera), dorsal scutum and anal operculum with white patches, weak armature on male leg IV (larger much smaller than segment diameter) and body shape.

Composition. Thereza albiornata Roewer   , T. amabilis   Pinto-da-Rocha, T. murutinga   sp. nov., T. poranga   Pinto-da-Rocha, and T. speciosa (Roewer)   .

Distribution. Occurs in coastal mountain ranges from the states of Espírito Santo to Santa Catarina.
