Material examined: MIMB 16535, 12 specimens, 12 10.5′ N, 109° 17′ E, 12 m, 18 Apr 2006, Mot Island, Nha Trang Bay, South China Sea, Vietnam, coll. T.N. Dautova

Description. Living and preserved colonies are tree-like and 27–34 mm high ( Figs. 15 View FIGURE 15 , 16 View FIGURE 16 ); some of them are united at the base making them multi-stalked colonies ( Fig. 16 View FIGURE 16 B). The lobes bear secondary lobules 2–4 mm across, with rounded tips. Their surface is uneven due to tiny pits of the retracted polyps. The distance between the centers of these pits is 0.8 to 1 mm. The sterile stalks are oval in cross-section and only slightly grooved longitudinally.

The polyps are armed with warty rods and flattened spindles ( Fig. 17 View FIGURE 17 A). The rods are mostly 0.075 to 0.14 mm in length and slightly flattened. Some of them are club-like because of more developed prominences at one end. The spindles are distinctly flattened and often curved. They are 0.75 to 0.23 mm long and bear warts.

The sclerites of the lobule surface are warty clubs, club-like spindles and small spindles varying in length from 0.05 up to 0.7 mm. The clubs in most cases have a distinct central wart. The shafts of the smallest clubs are straight or slightly curved, sometimes with outgrowths at the end ( Fig. 17 View FIGURE 17 B). The longer clubs may have narrow, straight handles or may be thickened and flattened for the whole or lower half of the handle ( Fig. 18 View FIGURE 18 A, C). The clubs with the thickened handles can be up to 0.7 mm long; the largest ones are very remarkable ( Fig. 18 View FIGURE 18 C, a, b). The central wart on their heads can stand apart, but is often indistinct because all head warts are well-developed, plump, and crowded close together ( Fig. 18 View FIGURE 18 B). The thickened and flattened club-like spindles with non-ordered outgrowths on one end are transitional from thickened clubs to warty spindles with quite symmetrical ends ( Fig. 18 View FIGURE 18 C, d). Club-like, thin spindles occur as well as thin spindles with few warts and spines ( Fig. 18 View FIGURE 18 C). Crosses are rare ( Fig. 17 View FIGURE 17 B).

spindles are ornamented with complex crenellated warts, which sometimes are joined into flat solid plates ( Fig. 21 View FIGURE 21 C, a).

Coloration. The alcohol-fixed specimens are creamy white. The living colonies have creamy or yellow lobes and grey stalk; polyp tentacles are colorless.

Distribution. Ceylon (Gulf of Manaar), a new record for Vietnam (South China Sea, Nha Trang Bay).
