Remarks.

Cylindroniscus flaviae shows preference for organic matter deposits and highly humid areas in the aphotic zone (Fig. 2B ). The organic matter was observed in several conduits of the Gruta da Tapagem, always far from the touristic stretches, and it was composed of particulate vegetal debris or small tree branches. The environmental variables along the cave ranged from 19.9 °C to 20.4 °C and the relative air humidity from 95% to 99.1%. The individuals demonstrated sensitivity to the flash lights of the lanterns, always moving in opposite direction.

Distribution.

This species is recorded from several caves in the Açungui geomorphological group (see Campos-Filho et al. 2017).
