| Summary: | After the description of <i>Gobius incognitus</i> Kovačić & Šanda, 2016, all previous knowledge about the geographic distribution of <i>Gobius bucchichi</i> Steindachner, 1870, as well as its ecology and biology, became obsolete, since it represented the data from the mixture of two species. The known geographic distribution of <i>G. bucchichi</i> and <i>G. incognitus</i> is revisited by validating previously published records, but also and foremost by integrating many new photographic records posted by anglers and divers on social media and on citizen science databases. The present research uses only positively identified records with exact data on locality, coordinates and date of collecting. A total of 1024 confirmed records were collected and retained for inferring distribution maps: 805 records of <i>G. incognitus</i> and 219 records of <i>G. bucchichi. Gobius incognitus</i> is a widespread Mediterranean Sea species with limited presence in the Lusitanian province of the Eastern Atlantic Ocean. It is absent from the Sea of Marmara and the Black Sea. <i>Gobius bucchichi</i> is recorded only in the eastern half of the Mediterranean Sea, from the Adriatic to the Aegean Sea, and in the Black Sea and Sea of Marmara.
