Etymology.

The new name (male gender) means “ fish that swims fast ” (from the classic Greek ichthyos = fish, tachys = fast, nectes = swimming). The name intends to keep the initial meaning of Tachynectes (fast swimmer), but adding a prefix indicating the taxonomic group.

Comments.

The homonymy of Tachynectes Fitzinger, 1843 and Tachynectes von der Mark, 1863 was already acknowledged by White and Moy-Thomas (1941), but overlooked by subsequent authors.
