GenBank accession numbers.

Diagnosis.
Shell conical with four plates, tubiferous; radii solid; tergum broad, apex not beaked.
Description.
Shell with four inseparable, multi-tubiferous plates, greyish black to purplish-grey or deep green to green, surfaces with mosaic scales pattern radiating randomly from base to apex, internal surface of parietes smooth, white with dark grey striations around aperture; radii solid (Fig. 16a-c View Figure 16 ); basis membranous; scutum larger than tergum, triangular, external surface with horizontal striations, occluding margin with fine teeth; tergum broad, higher than wide, apex not produced as beak, spur sharp, basi-scutal angle smaller than that of Tetraclita squamosa (Fig. 16d, e View Figure 16 ); external surface of operculum grey and yellowish-light brown, internal surface greyish-dusky green; mandible with four large teeth; maxillule not notched with eleven setae; labrum with five small teeth on each side; cirrus I possessing serrulate setae. Basal length 12.1-21.6 mm, basal width 18.1-21.8 mm, height 7.3-10.4 mm. Orifice length 3.2-5.3 mm, orifice width 2.4-4.2 mm (measurements for five specimens are presented in Suppl. material 1: Table S15).
Distribution.
Tetraclita kuroshioensis was previously recorded from Japan, Taiwan, Palau, and Thailand ( Chan et al. 2009a; Pochai et al. 2017). In this study, T. kuroshioensis was found on Ambon Island (at Hatu and Ureng) and Saparua Island (at Dermaga Ihamahu) on rocks and concrete wall of a port (a map with the occurrence of Tetraclita kuroshioensis in the Moluccas is shown in Suppl. material 1: Fig. S4).
Remarks.
Tetraclita kuroshioensis and T. squamosa share great morphological similarity. However, DNA sequences separate the two species ( Chan et al. 2007), which was confirmed in this study (Fig. 29 View Figure 29 ). Morphologically, the shape of the tergum is definitive; that of T. kuroshioensis is broader and the apex blunter compared to T. squamosa ( Chan et al. 2007).
