sp. nov. (Epinephelidae, Liopropominae), a new species of basslet from mesophotic coral ecosystems of Pohnpei, Micronesia.

A new species of the genus Gill found on the lower mesophotic coral ecosystem of Pohnpei, Micronesia, is herein described. differs from its congeners in coloration, number of lateral-line scales, number of pectoral fin rays, body depth, and snout length. is the 31 species in the genus.

, a new species of butterflyfish (Teleostei, Chaetodontidae) from Palau.

A new species of the butterflyfish genus (Chaetodontidae) is described from two specimens collected at a depth of 116 m off Ngemelis Island, Palau. is similar to Pyle & Kosaki, 2016 from the Hawaiian archipelago, and (Maugé & Bauchot, 1976) from the western Indian Ocean, but differs from these species in the number of soft dorsal-fin rays, size of head, body width, and body depth. There are also subtle differences in life color, and substantial differences in the mtDNA cytochrome oxidase I sequence (d ≈ 0.

Three new species of (Teleostei, Pomacentridae) from mesophotic coral ecosystems of the Philippines.

Three new species of (Perciformes, Pomacentridae) from the Philippines, collected between 75-150 m depth, are described by a combination of morphological features and their coloration. was found in Batangas and Oriental Mindoro, and differs from its congeners in body depth (2.1-2.

, a new basslet from deep coral reefs in Micronesia (Perciformes, Percoidei, Serranidae).

The new species is described from four specimens collected at depths of 115-148 m near Palau and Pohnpei in Micronesia. It differs from the other three species of this genus in life color and in certain morphological characters, such as body depth, snout length, anterior three dorsal-fin spine lengths, caudal-fin length, and other characters. There are also genetic differences from the other four species of (d ≈ 0.

, a new basslet (Perciformes, Percoidei, Serranidae) from deep coral reefs in the Northwestern Hawaiian Islands.

The new species is described from two specimens collected at a depth of 90-92 m off Kure Atoll and Pearl and Hermes Atoll, Northwestern Hawaiian Islands. It differs from the other two species of this genus in life color and in certain morphological characters, such as number of pored lateral-line scales, pectoral-fin rays, snout length, anterior three dorsal-fin spine lengths, dorsal-fin profile, and other characters. There are also substantial genetic differences from the other two species of (d ≈ 0.

Grammatonotus brianne, a new callanthiid fish from Philippine waters, with short accounts of two other Grammatonotus from the Coral Triangle.

In May 2014, a group of ichthyologists from the California Academy of Sciences and the Bishop Museum collecting fishes off the coast of Batangas, Luzon, Philippine Islands, obtained, in a depth of ca. 150 meters, four specimens of a species of Grammatonotus previously unknown to science. This new species, Grammatonotus brianne, is distinguishable from its described congeners by the following combination of characters: short anal-fin spines, rhomboid shaped caudal fin, lateral line usually disjunct, and live coloration.
