Distribution of this species will be corrected as more studies have confirmed or clarified its occurrence, together with the similar species Gobius incognitus. Further, the colouration and shape characteristics from the diagnoses given in Ref. 110727 could be used to confirm the identity, as either G. incognitus for G. bucchichi, of specimens shown in photographs or species information in published references for the Mediterranean and Atlantic samples as were used for this species in FishBase.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 1 - 8 m (Ref. 110727), usually 1 - 3 m (Ref. 110727). Subtropical; 15°C - 24°C (Ref. 27115); 47°N - 30°N, 6°W - 42°E
Mediterranean Sea: Confirmed only in the Adriatic and northern Ionian Sea. Recorded once in the Aegean Sea (R. Pillon, pers. comm.). All previous records outside this area are most likely for Gobius incognitus Kovačić & Sanda, 2016 (Ref. 110727).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 3 - 3.8 cm
Max length : 10.0 cm TL male/unsexed; (Ref. 4696)
soft rays: 13 - 14. This species is distinguished from its congeners by the following combination of characters: LL 51-55; predorsal scales 20-25; opercle naked (rarely with 2-4 scales visible); pectoral-fin rays 17-18; free tips on 3 upper pectoral rays moderately developed and the first ray shorter than half of the entire ray length; complete pelvic fin disc, its anterior membrane without lateral lobes; anterior oculoscapular canal with pore 'alpha' at rear of orbit; oculoscapular row x1 is not extending forwards to pore ß; suborbital row d is continuous; eye diameter 0.82-1.04 in snout length; there are 2 rows of elongated dots on the cheek and without dots between the middle of the cheek, the lower row starting anteriorly at the angle of mouth and going backwards across the cheek and opercle to the pectoral fin base, the upper row starting at upper lips, going posterodorsally to touch ventral margin of eye and continuing behind eye; upper mark on the pectoral fin single or doubled, reaching downwards to 6th - 7th rays counting from upper end (Ref. 110727).
All information on this speciesreamin to be reviewed because most likely applicable to Gobius incognitus. Use the current information with caution and criticism, and retain only those from the Adriatic and northern Ionian Seas. (Ref, 110727).
