A new species of Buenia (Teleostei: Gobiidae) from the western Mediterranean Sea, with the description of this genus

A new miniature gobiid species, Buenia massutii sp. nov. (Teleostei: Gobiidae) is described from the circalittoral bottom off the Balearic Islands, western Mediterranean. Phylogenetic analysis of the mitochondrial COI-barcoding fragment supports its species-level distinctiveness and the monophyly of the genus Buenia. A description and diagnosis of the genus Buenia is for the first time provided. Material of the new species was collected in 57-67 m depth from beam trawl samples carried out on red algae beds. The traits that differentiate the new species from two congeneric species are: anterior oculoscapular canal only semiclosed with pores sigma, lambda, kappa, omega, alpha, rho and additional pores and open furrows from interorbital part to pore. ; posterior oculoscapular canal absent ; suborbital row c with 5 papillae ; scales in lateral series 26-28 ; pectoral fin rays 16 ; the second spine of the first dorsal fin the longest, reaching to or behind posterior end of the second dorsal fin in males when folded down ; pelvic fin anterior membrane one sixth or less of length of spinous ray in midline depth ; head length 31.2-32.5% of standard length ; eye 32.8-35.7% of head length ; caudal fin length 21.5-24.0% of standard length.
