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.

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.

Four new species of the coral-associated gobiid genus Gobiodon were discovered in the Red Sea. Although several of these species are common not only in the Red Sea but also in the Indian and western Pacific Ocean, they have not been described before. Detailed descriptions of the four species are based on morphological and molecular genetic (mitochon-drial 12s and 16s rRNA) investigations. The new species, like most species of the genus, lack scales and have species-specific life colouration. Gobiodon bilineatus sp. nov. is the closest relative to G. quinquestrigatus (Valenciennes) and of G. sp. D (Munday et al.), and has five distinct, blue lines on the head as juveniles and subadults, which disappear in adults, and which are often uniformly orange-red with two distinct, vertical blue lines through each eye. Gobiodon irregularis sp. nov. has been confused with the former new species in the past, and is closely related to G. oculolineatus Wu, but is un-mistakable in live colouration. Juveniles are characterised by a transparent body, red bars on the head with bluish to greyish interspaces, and irregular red lines and dots on the nape and dorsally on the body. Adults are usually uniformly brown or green-brown, with only remnants of the bars through the eye and below the orbit. Gobiodon ater sp. nov. is a small, entirely black species and can be easily confused with other black species, although it is genetically clearly distinct from G. ceramensis Bleeker and its black relatives. Gobiodon fuscoruber sp. nov. is likely to be the closest relative of G. ater sp. nov., but is uniformly reddish-brown or brown, has bright median fin margins (at least in the Red Sea), and grows considerably larger than G. ater. It has been genetically determined that G. fuscoruber sp. nov. is identical with an Indian Ocean/western Pacific species that has been called G. unicolor Castelnau by several authors. However, examination of the holotype of G. unicolor, including the original description, revealed that the type species and original description are clear-ly different from the species frequently called G. unicolor. The holotype resembles G. histrio (Valenciennes) and the name G. unicolor must therefore be considered a junior synonym of G. histrio. As a consequence, a new name for this species is provided.

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.

The fishes of the blennioid family Tripterygiidae of the Red Sea are reviewed. Twelve species are recognised: Norfolkia brachylepis, Helcogramma obtusirostris, H. steinitzi and nine species of Enneapterygius. Enneapterygius qirmiz sp. nov. is described for a species originally described, but not named, by Clark (1980), of which the specimens on which she had based her description had become lost. Clark's (1980) Enneapterygius altipinnis is re-instated as a valid species, and its inclusion as one of a complex of several species is discussed. Enneapterygius ventermaculus reported as first record for the Red Sea. Detailed colour descriptions are given for all species, including their colour underwater where possible, as many of the species are cryptic and difficult to identify.
