The main habitat characteristics of Diglotta brasiliensis Caron & Ribeiro-Costa, 2008, a recently described species from the Neotropical region, are provided. The specimens were found inhabiting a 4 m wide-strip at the upper intertidal zone of two estuarine sand beaches (both located in the euhaline sector of the bay), with densities ranging from 13 to 80 individuals/m². In this zone, sediment is composed by moderate to very well sorted median sand with moisture content around 6.5%. The sediment organic matter and calcium carbonate contents varied from 0.08 to 0.13% and from 3.4 to 5.4%, respectively. At these places, D. brasiliensis was found coexisting with cirolanid isopods of the genus Excirolana Richardson, 1912 (Isopoda: Cirolanidae).
