Type material. Holotype: NHM1965.33.34, collected from and among farmed oysters in Binakayan, Cavite, Manila Bay, Philippines; Fig. 3. Paratypes: Nine specimens (6 “de-tubed”; 3 preserved within tubes). NHM1965.33.35 (1 spec.), NHM1965.33.36 (1 spec.), NHM1965.33.37 (1 spec.), NHM1965.33.38 (1 spec.), NHM1965.33.39 (1 spec.), NHM1965.33.40 (1 spec.), NHM1965.33.41 (1 spec.), NHM1965.33.42 (1 spec.), NHM1965.33.43 (1 spec.); all material collected from and among farmed oysters in Binakayan, Cavite, Manila Bay, Philippines.
Diagnosis. Tube white (Figs 1A–B), sub-trapezoidal in cross-section (Figs 1C–D). Radiolar crown attached to two lobes, with 12–17 radioles arranged in a circle in each lobe. Operculum funnel-shaped. Opercular endplate calcareous, circular, with deep concavity (Figs 2A–B, Fig. 3C), except in one specimen with a shallower endplate protruding slightly from opercular ampulla (Fig. 2C, red arrow) with indistinct, concentric ovoid-shaped markings (Fig. 2D). Collar chaetae absent, except in one specimen which had collar chaetae on both sides of body. Abdomen with 38–61 chaetigers, between one to three achaetous segments anteriorly.
Etymology. The specific epithet “manilensis” was originally coined by Pillai (1965) in his unavailable varietal name, as a reference to Manila Bay, where the species was found.
Remarks. We refer readers to Sivananthan et al. (2021) for a full description of S. manilensis sp. nov.. The reported count of seven specimens in Sivananthan et al. (2021) excluded three specimens that were preserved within their tubes. Details of holotype and paratypes of S. manilensis sp. nov. are provided in Supplementary Information, Table S1.
