Pisces Callanthiidae Grammatonotus bianchi sp. nov. taxonomy R/V Dr. Fridtjof Nansen trawl surveys Myanmar


A new splendid perch, Grammatonotus bianchi sp. nov. is described on the basis of two specimens (45.9–68.7 mm SL) collected at 184 m depth in the Andaman Sea off the coast of Myanmar during bottom surveys conducted by the R/V Dr Fridtjof Nansen in 2018. The new species can be distinguished from all congeners by its large head (37.7–38.6% SL), large orbit (14.4–15.3% SL), caudal-fin shape, and fresh coloration. A key to Indian Ocean species of Grammatonotus is provided.
