GenBank accession number.

18S (MK981384).

Diagnosis.

Parietes low with wall spreading; peritreme slightly toothed; base calcareous with two rows of irregular shape and size of parietal tubes; tergum with broad spur; lateral scutal depressor crests numerous and deep; five toothed mandibles; segments of posterior cirri with four pairs spines.

Synoptic description.

Shell four plated, conical, whitish with spots of purple in upper part (Fig. 19a ); parietal tubes irregular shape, size unequal (Fig. 19b ); radii moderately wide, summits oblique, interior of irregularly branching ridges with solid interspaces (Fig. 19c ); orifice trigonal; scutum and tergum coalesced, strongly articulated (Fig. 19d, e ); tergum with broad spur, lateral tergal depressor crests on basal margin long, with numerous, deep crests, lateral scutal depressor crests numerous, deep; mandible with five teeth (Fig. 19f ). Basal length 15.4-22.8 mm, basal width 13.8-22.8 mm, height 5.3-6.9 mm. Orifice length 5.2-6.9 mm, orifice width 4.6-5.4 mm (measurements for four specimens are presented in Suppl. material 1: Table S18).

Distribution.

Neonrosella vitiata was previously recorded from the Indo-west Pacific, Indian Ocean, Nicobar Island to Australia, Indonesia, Malay Archipelago, Sulu Archipelago, Philippines, and the Pacific Ocean ( Jones and Hosie 2016). Recently, Neonrosella vitiata also was discovered in the Andaman Sea of Thailand ( Sukparangsi et al. 2019). In this study, N. vitiata was found on Ambon Island (at Liang), Banda Island and Saparua Island (at Tuhaha) on port poles, reef and stones (a map with the occurrence of Neonrosella vitiata in the Moluccas is shown in Suppl. material 1: Fig. S7).

Remarks.

Neonrosella vitiata can be distinguished by its irregular parietal tubes, the shape of the terga, the five toothed mandibles and four pairs of spines on the segments of the posterior cirri ( Darwin 1854).
