Ocorrência de Diglotta brasiliensis (Coleoptera: Staphylinidae: Aleocharinae) em duas praias estuarinas da Baía de Paranaguá, sul do Brasil

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).
