Tonicia (Lucilina) perligera ; Slieker 2000: 50, pl. 13, fig. 27; Anseeuw & Terryn 2004: 15, figs 24–31, 48–49; Kaas et al. 2006: 319, fig. 131 (bibliography and synonymy).

Type: Holotype ZMB Moll. 102059 ( Kilias 1995: 167).

Type locality: Red Sea.

Material examined: M13: 1 intermediate valve.

Remarks: Detailed descriptions of this species are given by Strack (1993) and Anseeuw & Terryn (2004).

The investigated material comprises of an intermediate valve only, but the characteristic sculpture, formed by large, well separated granules, covering the entire tegmentum surface, is sufficient to identify the species.

Lucilina perligera seems to be a rather rare species, and only a few living specimens are known ( Anseeuw & Terryn 2004). It was considered endemic to the Red Sea, so this new record considerably extends the distribution of this species.

Distribution: Lucilina perligera is reported from the northern Red Sea and the Maldive Islands.
