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 ocu-loscapular canal only semiclosed with pores σ, λ, κ, ω, α, € 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.

Diplecogaster umutturali sp. n. is described from five specimens, ranging from 9.5 to 26.9 mm in standard length. This clingfish is known to occur only at three localities along the northern Levant coasts, eastern Mediterranean Sea and is the third known species of the genus Diplecogaster in the Mediterranean and Black Seas. The species is distinguished from all its congeners in having a small snout, short caudal peduncle, large eyes, short anal fin and upper attachment of gill membrane opposite the 7th-8th pectoral ray. Diplecogaster umutturali sp. n. shows a 5.3% genetic divergence from its close relative D. bimaculata at the cytochrome oxidase I locus (COI). http://www.zoobank.org/urn:lsid:zoobank.org:pub:376298FE-C8A7-44BB-9B12-721E41D7F355 © 2017 Taylor & Francis

The high resemblance of Silhouettea chaimi Goren, 1978 to two Papillogobius species, P. melanobranchus and P. reichei was noticed from their published descriptions. The comparison of types of S. chaimi with comparative material of P. melanobranchus and P. reichei confirmed the lack of morphological differences between two nominal species, S. chaimi and P. melanobranchus. Therefore, S. chaimi is placed as a junior synonym of P. melanobranchus. © 2013 Magnolia Press.

Two goby species endemic to the Mediterranean Sea were collected from the northern and southern Aegean Sea. A new record of Millerigobius macrocephalus from the area is presented and the occurrence of Zebrus zebrus off Turkish coasts is substantiated.

A new species of the genus Hetereleotris is described from the Gulf of Aqaba, Red Sea, on the basis of two specimens. Hetereleotris psammophila sp. nov. is unique among the species of the genus Hetereleotris, except for H. diademata, in lacking scales and head pores. The new species differs from the morphologically similar H. diademata in having fewer rays in the second dorsal and anal fins, and in coloration. The habitat preference of the new species for open sand area close to coral reefs in 8-21 m and its nocturnal habits are unusual for species of the genus Hetereleotris.Copyright © 2014 Magnolia Press.

Two new species of the gobiid genus Cabillus, C. nigromarginatus sp. nov. and Cabillus nigrostigmus sp. nov. are de-scribed. Cabillus nigromarginatus (from Rodrigues, Western Indian Ocean) is distinguished from congeners by having 18-20 pectoral-fin rays; predorsal area naked; two scales with enlarged ctenii ventrally and dorsally at the caudal-fin base; head with anterior and posterior oculoscapular, and preopercular canals, with pores 1, 2, and, respectively; the body with four midline lateral blotches, with two or three of them expanding upwards in dorsal saddles; a dark triangular blotch at caudal-fin base; and predorsal with pigmentation at lateral edges forming a rectangle. Cabillus nigrostigmus (from the Red Sea) is distinguished from its congeners by having 19 pectoral-fin rays; transverse scale series 7; nape scaled, median predorsal scales 7; body depth 5.8-6.0 in SL; snout length 1.5-1.9 in eye diameter; caudal-peduncle depth in its length 2.4-2.5; a broad dark brown bar below first dorsal fin beginning anteriorly at the level of fourth spine of the first dorsal fin; elongate black blotch along posterior half of first dorsal fin extending into the sixth spine and adjacent membranes; and midlateral black spot at the end of caudal peduncle followed by S-shaped dark bar. Cabillus macrophthalmus is recorded for the first time in the Western Indian Ocean (Red Sea and Seychelles) and rede-scribed. Copyright © 2013 Magnolia Press.

De Buen's goby, Buenia affinis, is a very small Mediterranean goby (38.8 mm TL) inhabiting sandy infralittoral bottoms and known only from a few published records. Some aspects of reproduction and growth of B. affinis were investigated from a population collected in the Kvarner area (north-eastern Adriatic Sea). Sampling was carried out by SCUBA diving between May 2003 and April 2004. The sex ratio did not differ significantly. The estimated length at sexual maturity was 26.1 and 27.4 mm for females and males, respectively. The spawning season extended from February to July. The absolute fecundity (F) ranged from 457 to 714 eggs per individual (mean ± SE, 556 ± 25). Based on the length frequency distribution analysis throughout the year and seasonal growth bands on sagittal otoliths, B. affinis was assumed to be an annual species.

Prior to the present study, the gobiid biodiversity of the Adriatic Sea varied significantly between the northern (98% of the known Adriatic gobiid biodiversity) and central (89%) as compared to the southern Adriatic Sea (39%). Thirteen species are newly recorded for the southern Adriatic area and one for the central Adriatic. The relatively small collecting effort in this survey produced a large increase in the known gobiid biodiversity, which suggests that the low number of known Adriatic gobiid species in the southern Adriatic mirrors only sampling intensity and not the real species richness of the area. The gobiid zoogeography in the Adriatic is compared with that of the Mediterranean.

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 α at rear of orbit; oculoscapular row x1 not extending forwards to pore β; suborbital row d discontinuous with large gap below suborbital rows 3 and 4; eye diameter 1·08-1·32 in snout length; by pigment rows on cheek and pigmentation on pectoral-fin base. © 2016 The Fisheries Society of the British Isles.

The checklist of gobiids from Crete includes 17 species. The published data on gobies from Crete have so far been scarce. Ten species are the new findings from the present research. Two species, Corcyrogobius liechtensteini and Gammogobius steinitzi, from the north coast of Crete, represent the first finding of these species outside the north-western Mediterranean and the Adriatic Sea. It is expected that the actual gobiid biodiversity of Crete is much higher.
