| Comment | Synonymy: SCHÄTTI & GASPERETTI (1994) did not accept the placement of L. gaddi as a subspecies of L. diadema. The divergence between L. gaddi and species of genus Lytorhynchus ranged from 4–5%, 2–4%, 5–6% for the two concatenated genes, 16S and 12S, respectively (Alshammari et al. 2021.
