GenBank accession numbers.
COI gene (MK995360-MK995362), 18S (MK981368-MK981373).
Diagnosis.
Shell conical with four plates, tubiferous; radii solid; tergum narrow, concaved, apex beaked.
Description.
Shell consisting of four fused, inseparable plates (Fig. 17a View Figure 17 ), parietes with eight rows of multi-tubiferous parietal tubes (Fig. 17b View Figure 17 ), external surface with longitudinal lines from base to apex, internal surface smooth, white with purplish grey striations close to aperture; orifice rhomboidal; basis membranous; shell greenish with brownish grey (Fig. 17a View Figure 17 ), external surface of operculum brownish grey, internal surface purplish grey; scutum triangular, larger than tergum, external surface with horizontal striations, occluding margin with very shallow teeth; tergum narrow, apex beaked, spur long, sharp (Fig. 17c, d View Figure 17 ); mandible with four large teeth, first tooth with three small spines, lower margin pectinate (Fig. 17k View Figure 17 ); maxillule notched with two large setae above notch, elevan small setae below notch (Fig. 17j View Figure 17 ); labrum with four large teeth on each side of notch; cirrus I with bidentate serrulate setae (Fig. 17e View Figure 17 ). Basal length 20.1-30.2 mm, basal width 19.3-28.3 mm, height 11.9-14.2 mm. Orifice length 4.4-7.9 mm, orifice width 3.4-7.2 mm (measurements for five specimens are presented in Suppl. material 1: Table S16).
Distribution.
Tetraclita squamosa is widespread in the Indo-Pacific region, Australia, South China coast, and Taiwan (Newman 1978; Jones et al. 2001; Chan et al. 2009a). In this study, T. squamosa was found on Ambon Island (at Alang, Dermaga Liang, Dermaga Tulehu, Doc Tawiri, Gudang Arang, Hila, Hutumuri, Leahari, Tawiri, Tulehu, Waai, Asilulu, Wakasihu) and Saparua Island (at Benteng Duurstede and Teluk Saparua) on stone, rocks, shipyards, concrete bridges and walls of the port (a map with the occurrence of Tetraclita squamosa in the Moluccas is shown in Suppl. material 1: Fig. S4).
Remarks.
Tetraclita squamosa has characteristic green parietes ( Yamaguchi 1987) and a wide distribution throughout the Indo-Pacific ( Newman and Ross 1976). However, the taxonomy of Tetraclita squamosa has been confusing due to a high degree of morphological variation, and it is now considered a species complex. Tetraclita squamosa and Tetraclita japonica can be separated using characters such as the shape of the parietes, scutum geometry, and mandible structures ( Darwin 1854; Pilsbry 1916). In addition, a key character for T. squamosa is the tergum with a beak on its apex ( Chan et al. 2009a).
