Tubastraea, commonly known as sun coral, is a genus of brightly coloured azooxanthellate corals in the family Dendrophylliidae. The diversity of this genus is low, with only seven recognized species. Herein, we describe Tubastraea megacorallita sp. nov. from Hong Kong based on morphological and molecular analyses. This new species exhibits several characteristics of the genus including being colonial, having a rough texture of corallum and no epitheca. It can be distinguished from its congenerics by bigger corallites, and the Pourtals plan arrangement of its septa. The rDNA gene sequences (consisting of ITS1, 5.8S, ITS2, 18S and 28S) showed 2.455.18% divergence from those of its closest relatives, T. coccinea and T. micranthus.
长枝鹿角珊瑚，俗称太阳珊瑚，是属于鹿角珊瑚科的一科颜色鲜艳的无共生藻珊瑚。该属物种多样性低，仅有七个被认可的物种。本文根据形态学和分子分析，描述了来自中国香港的长枝鹿角珊瑚一新种。该新种具有鹿角珊瑚属的几个特征，包括群体生活、珊瑚骼表面粗糙且无表皮层。通过比较珊瑚骼上的珊瑚虫体腔孔大小，以及隔片的 Pourtals 平面排列，可将其与近似种相区分。rDNA 基因序列（包括 ITS1、5.8S、ITS2、18S 和 28S）显示与亲缘关系最近的物种 T. coccinea 和 T. micranthus 的差异为 2.455.18%。
