Figure 3.Holotype (RMNH Coel. 40138) and three paratypes (RMNH Coel. 40139) of Leptoseris troglodyta sp. n.from Palau. Scale bars: 1 cm. a Holotype consists of four calices: one (most left) has fused mid-height its calyx with two totally fused calices (centre), while another (right) has fused only with its corallum margin to those at the centre and the rest of its calyx has remained separate b Paratype: two separate calyces c Paratype: single calyx d Paratype: two fused calices. Scale bars: 1 cm.
