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).
