Checklist of Gobiodei fishes of the world: an update

In a previous work the Author proposed a checklist of Gobioidei of the world listing 2310 valid species. In the present paper an updated checklist is presented, including six new genera (Formosaneleotris, Birdsongichthys, Ilogton, Lepusigobius, Marcelogobius, Peter, and Tempestichthys), whereas one (Imu) has been resurrected from synonymy. The total number of new species is 199. However, 22 nominal species which has been regarded as valid are now considered synonyms, and 11 are resurrected bringing the total number of Gobioidei fish species to 2498 and with a pace of 34-35 new species per year. Genus revision has in some instances reduced the number of valid species (see for example the case of Sicyopterus). However, many undescribed species are known to exist and in some cases they are indicated in the present checklist.
