Remarks.

Mendes and Andersen (2009) stated that the superior volsella has a "marginal row of flattened setae". In lateral view (Fig. 2B ), it can be seen that the volsella is quite wide medially with a row of lamellae apparently covered with weak microtrichia.

Distribution

(Fig. 16A ). The species was originally described by Mendes and Andersen (2009), based on a single male from the Espírito Santo State; the range is now extended to the Mato Grosso and Rondônia States in central and northern Brazil.
