Gobius bucchichi Steindachner, 1870 (Fig. 34)—Bucchich’s Goby Gobius bucchichi Steindachner, 1870: 627, type locality: Adriatic Sea, Croatia, Hvar. Size. Known adult size about 9 cm total length. Morphology. D VI + I,14; A I,13–14; P 17–18. Medium-sized goby with moderately long body, and large head with short, slightly acute and oblique snout. Caudal peduncle deep, but lower than body depth. Dorsal fins of similar height, the first dorsal fin may be slightly taller, with more or less rounded margin and no elongate spines. Caudal fin rounded. Scales present on body and on predorsal area, usually visible on photographs, at least dorsally (Kovačić & Šanda 2016). Live coloration. Body pale gray, pale yellowish, or yellowish brown with pattern of brown dots forming longitudinal lines. Dots are most marked along the lateral midline but always remain separated and generally form a continuous row with no marked spaces (Fig. 34). Eyes with a conspicuous horizontal dark brown stripe through the center, narrowly continuing on postorbital part of head as series of small close-set spots, an irregular longitudinal marking along the upper iris, a variable number of additional markings in orbit’s upper half but unmarked in ventral half, except sometimes with a small dot in its anterior portion. Snout with dark dashes forming M-shaped line. Usually it has only 2 longitudinal rows of dots on the cheek with a large unmarked area in the middle (Fig. 33a). Rarely, a few dots are visible also in the middle cheek but usually limited to the anterior part of the cheek, very close together, well aligned and not parallel to the lower row. Posterior angle of mouth without a well-defined dark dot (Fig. 33a), so the lower row of dots, which runs along the ventral edge of the cheek, starts with 2 dashes never preceded by a marked dot on the corner of the mouth (Kovačić & Šanda 2016; Renoult et al. 2022). Similar species. Gobius incognitus, G. fallax. Habitat. Infralittoral species, known from 1–8 m depth from all kinds of rocky substrata: gravel, cobbles, boulders and bedrock, but on sand only when it is mixed with a hard substratum, never on pure sand. The substratum was bare or covered with short thallus algae (Kovačić & Šanda 2016). Geographic distribution. Presently known from the eastern coast of the Adriatic Sea, it is common from the Gulf of Trieste (Tiralongo & Pillon 2020) to southern Croatia (Kovačić & Šanda 2016); there is only one record in the Ionian Sea from Butrint, southern Albania (Kovačić & Šanda 2016), and a record in the Aegean Sea from Kondyli beach, eastern Peloponnese (Tiralongo & Pillon 2020). Population from the Black Sea more similar in pattern of coloration to G. bucchichi than to G. incognitus in absence of black dot at the corner of mouth and any mark ventrally on iris (Vasil’eva 2007; Boltachev & Karpova 2017), and requires additional study., Published as part of Kovačić, Marcelo, Renoult, Julien P., Pillon, Roberto, Svensen, Rudolf, Bogorodsky, Sergey V., Engin, Semih & Louisy, Patrick, 2022, Identification of Mediterranean marine gobies (Actinopterygii: Gobiidae) of the continental shelf from photographs of in situ individuals, pp. 1-103 in Zootaxa 5144 (1) on page 53, DOI: 10.11646/zootaxa.5144.1.1, http://zenodo.org/record/6601561, {"references":["Steindachner, F.

In this work, we present first data on biological and ecological aspects of Gobius incognitus from specimens from the Ionian Sea (central Mediterranean Sea). In particular, we provided first data on habitat preference, diet and length-weight relationship of G. incognitus on material with confirmed species identity. The species preferred “mixed bottom” (sand and rocks), where it reached relatively high abundances. The diet analysis showed that G. incognitus is a generalist and opportunistic feeder. However, small benthic crustaceans were the most important prey group. The mean total length of specimens was 6.72 ± 1.85 cm and the growth was positive allometric., U ovom radu iznose se prvi podatci o biološkim i ekološkim značajkama vrste Gobius incognitus na temelju uzoraka iz Jonskog mora (središnji dio Sredozemnog mora). Posebno se ističu podatci o staništu, prehrani i dužnsko - masenom odnosu. Vrsta Gobius incognituspreferirala je „miješano dno“ (pijesak i stijene), gdje je dostigla relativno veliku brojnost. Analiza prehrane pokazala je da G. incognitus slijedi oportunistički način prehrane. Međutim, mali bentoski rakovi bili su najvažniji plijen. Srednja ukupna dužina iznosila je 6,72 ± 1,85 cm, a rast je bio alometrijski pozitivan.

A new species of the gobiid genus Gobius (Gobiidae, Perciformes), Gobius incognitus sp. nov. is described from the Mediterranean Sea, and its most morphologically similar species Gobius bucchichi is redescribed. The new species is distinguished from its congeners by: scales in lateral series 51-59 ; predorsal scales 25-35 ; opercle scaled in adults with 10-16 scales present ; pectoral fin with ray count 18-20 and free tips on upper rays well developed and on the first ray longer than two thirds of the entire ray length ; pelvic disc complete and with well-developed anterior membrane without lateral lobes ; anterior oculoscapular canal with pore at rear of orbit ; oculoscapular row x(1) not extending forwards to pore ; suborbital row d discontinuous with large gap below suborbital rows 3 and 4 ; eye diameter 108-132 in snout length ; by pigment rows on cheek and pigmentation on pectoral-fin base.
