Salvi et al. (2022) introduced the new species Ostrea oleomargarita in the on-line-only journal Journal of Zoological Systematics and Evolutionary Research. However, this name was not registered in ZooBank and under ICZN rules (ICZN 2012; Krell and Pape 2015) this name is not currently available. Unfortunately, the Journal of Zoological Systematics and Evolutionary Research was unable to publish a corrigendum in 2022. Therefore, we provide here a Code-compliant description of Ostrea oleomargarita Oliver, Salvi, and Al-Kandari, sp. nov. as reported in Salvi et al., (2022) with the ZooBank registration number of the publication. See Salvi et al. (2022) for detailed results of phylogenetic, species delimitation, and morphological analyses on which the systematic assessment of this new species was based. A further emendation to Salvi et al. (2022) concerns the scale bars in Figs 6 and 7 that were wrongly modified during the editorial process but are correctly shown here in Figs 1 and 2.

Shell description. Small shells up to 25 mm in height (beak to ventral margin); dimensions of upper valve of holotype are 20.2 × 17.5 mm. Shell thin but robust. Approximately circular, oval to pyriform.

Lower valve shallowly cupped to irregular; cemented for most or all of its attachment, margin smooth or, if free, then finely plicate. Non-nacreous margin very narrow. Ligament area narrow, elongated in some. Prominent catachomata on both anterior and posterior dorsal margins. Adductor muscle large, reniform. Interior colour flushed olive-green, paler in some smaller shells, most with a distinct narrow brown marginal band.

Upper valve flat, irregular to domed. Anachomata corresponding to catachomata. Sparse elongate tubercles (lophine pustules) on posterior ventral edge in some valves. Internal colour as that of lower valve. Outer surface usually obscured by epifaunal growths, typically Bryozoa, calcareous algae, worm tubes, or other oysters. Sculpture mostly of flattened foliar scales, some areas finely tubercular; colour of radial bands rust brown to black on a grey-beige ground, some almost uniform ground colour. Thin chalky layers present most visible in attached valves.

Type locality. Kuwait, Kuwait City, Al Sha’ab, 29.3675°N, 48.0244°E. Intertidal, under rocks.

Distribution. Intertidal shores of Kuwait.
