A new species of goby, Eviota rubriceps, most similar to E. nigrispina, is described from Indonesia, Papua New Guinea, and the Philippine Islands. Both species have the lower two thirds of the body dark in preserved specimens, belong to the cephalic sensory-pore pattern group 2 of Lachner and Karnella (1980), have an 8/7 dorsal/anal formula, and unbranched pectoral-fin rays. Eviota rubriceps differs from E. nigrispina in live and preserved coloration and in caudal-peduncle depth. The descriptions of E. mikiae and E. raja are expanded based on additional materials.

Navigobius kaguya is described on the basis of two specimens from the Ryukyu Islands, Japan, and Luzon, Philippines. It differs from other described species of the genus in live coloration, and in having: second dorsal-fin rays I,16; anal-fin rays I,16; pectoral-fin rays 21–22; gill rakers 5–6 + 17; and first dorsal fin weakly to moderately incised between spines, taller than second dorsal. It closely resembles an undescribed species from Bali and the Maldives, but differs in lacking an orange-red mid-lateral stripe. The possible placement of Navigobius khanhoa in Oxymetapon is discussed.

A new species of Ituglanis is described from rio Iratapuru, near the rio Jari, Amapá, Brazil. The new species is distinguished from all congeners by the reduced number of post-Weberian apparatus vertebrae (36 or 37); the low number of paired ribs (2); the low number of interopercular odontodes (12–15); the number of branchiostegal rays (7 or 8); the presence of elongated fontanel in parieto-supraoccipital; the pectoral-fin rays (i,5); head length (18.9–25.0); and the presence of pores supraorbital s1, infraorbitals i1 and i3 of the laterosensory system. The new taxon has a reduced body size and fully ossified skeleton, but does not display a large number of paedomorphic traits compared to congeners. Comments about taxonomy and intrageneric comparisons are made, and paedomorphic in Ituglanis is discussed. Thoughts about conservation of the new species are presented.

Rineloricaria daraha, new species, is described from the rio Daraá, tributary of rio Negro, northwestern Amazonas State, Brazil. The new species is diagnosed by having seven branched pectoral-fin rays, finger-like papillae on the lower lip, a large multi-angular preanal plate, and at least four quadrangular plates of variable size surrounding the preanal plate. The new species is known only from rio Daraá and its waterfalls.

A new species of the genus Osteobrama is described from the Mahanadi River, Tikarpada, Angul District, Odisha state, India. Osteobrama tikarpadaensis, new species, differs from its congeners in having two pairs of minute barbels; iii–iv unbranched dorsal-fin rays with 25–33 serrae on the last unbranched ray; 15–16 branched pectoral-fin rays, and 25–27 branched anal-fin rays. The status of Osteobrama dayi is discussed and shown to be a valid species. A key to the species of the genus is provided.

Gorogobius stevcici sp. nov. is described from the São Tomé Islands, Gulf of Guinea. Although it exhibits the unique combination of characters of Gorogobius Miller, it differs from present generic diagnosis of that genus. Therefore, a revised generic diagnosis and description of Gorogobius is provided. The new species differs from its only congener, G. nigricintus, by (1) presence of pore β; (2) row g anteriorly ends more or less in front of row o; (3) transverse interorbital row p present; (4) snout with four median preorbital rows; (5) 37–41 vs. 29–33 longitudinal scale rows; (6) 22–24 vs. 18 predorsal scales; (7) 9 vs. 10–11 anal fin rays; (8) 17 vs. 18–20 pectoral fin rays; (9) coloration.

A new species of small-sized scorpionfish, Scorpaena bulacephala, is described on the basis of seven specimens collected from off Norfolk and Lord Howe Islands, northern Tasman Sea, southwestern Pacific Ocean, at depths of 86–113 m. The new species is closely related to a Hawaiian endemic species, S. colorata. The two species are distinguished from other Indo–Pacific species of Scorpaena by the following combination of characters: exposed cycloid scales covering the anteroventral surface of the body and pectoral-fin base, the lateral surface of the lacrimal without spines, and 17 pectoral-fin rays. The new species differs from S. colorata in having 39–44 longitudinal scales rows and relatively short fin spines and rays, especially short longest pectoral-fin ray (31.5–33.5% of standard length). Morphological changes with growth and sexual dimorphism of the new species are also discussed.

Plectranthias cruentus new species is described from the holotype and two paratypes collected off Ball’s Pyramid and a paratype from Lord Howe Island. It resembles P. pelicieri Randall & Shimizu 1994 in live coloration and most morphological details, including absence of predorsal scales anterior to the supratemporal commissure, but differs in having the fifth or sixth (versus third) dorsal-fin spine longest, at least some pectoral-fin rays branched (versus all unbranched), and inconspicuous (versus distinct) serrations on the interopercle. It also differs in live coloration details.
