Distribution and ecology.

The WPD checklist only lists four species of the subgenus Reniera recorded from marine ecoregions of Indonesia with two as doubtful species, Haliclona ( Reniera) cinerea (Grant, 1826) (doubtful species), Haliclona ( Reniera) fascigera ( Hentschel, 1912) , Haliclona ( Reniera) infundibularis (Ridley & Dendy, 1887) (doubtful species), and Haliclona ( Reniera) venusta ( Bowerbank, 1875) , but none of these species were registered in the Spermonde Archipelago ( Putra et al. 2023). This report presents a new record of Haliclona ( Reniera) venusta from the Spermonde Archipelago (Samalona Island; reef flat). Previously, this species has been only reported from Malacca Strait ( Bowerbank 1875).
