Remarks.

The genus Parviplana comprises four species and is one of the least numerous genera within Polycladida . Parviplana jeronimoi is a very common species in Cadiz and Sancti Petri (Chiclana). Nevertheless, this species has not been reported in other localities until now. The other species of the genus are Parviplana hymani Faubel, 1983 , and P. lynca (Du-Bois Reymond Marcus, 1958) , which are from the Pacific and West Atlantic Oceans, respectively. Finally, after the Iberian species were described, P. sodade was described by Cuadrado et al. (2021) from Cape Verde.

Biology.

This species was collected and always observed under stones in the intertidal zone.

Distribution.
