Based on morphological, chemical, and phylogenetic analyses, a new species of the lichenized fungal genus Synarthonia, Synarthonia hainanensis, is described. This species is currently known only from Hainan Province. Synarthonia hainanensis is characterized by whitish-green thallus, short lirelliform to elongate, reddish-brown to black and epruinose ascomata, I+ reddish-purple hymenium, K/I- blue distinct ocular chamber in the asci, hyaline, 4-septate, and oblong-ovoid ascospores with the size of 18-24.5 × 6.5-9.5 µm. Molecular data, detailed taxonomic description, and images illustrating the morphological and anatomical characteristics of the new species are provided. A discussion on the differences between the new species and its similar species is also included. In addition, a key to 25 species of this genus is presented herein.
