Racekiela andina sp. nov. (Spongillida: Spongillidae): first report of a freshwater sponge from the Venezuelan Andes
The genus Racekiela Bass & Volkmer-Ribeiro, 1998 comprises six species of freshwater sponges distributed along the Palaearctic, Nearctic and Neotropical regions (Van Soest et al. 2017). They are characterized by an isodictyal skeleton solely of acanthoxeas, sparse spongin fibers, and tri-layered...
