Redescription of Chelidoperca barazeri, with a revised key and literature review to species of Chelidoperca in Taiwan (Perciformes: Serranidae).

Chelidoperca barazeri Lee, Lee, Matsunuma & Chen, 2019 is redescribed based on two sub-adult types and 12 additional non-types specimens collected from the type locality and southwestern Taiwan, respectively. The identification of the additional specimens were supported by morphological and/or molecular approaches. C.

Redescription of the serranid perchlet Chelidoperca pleurospilus (Günther, 1880).

Chelidoperca pleurospilus (Günther, 1880) (Perciformes: Serranidae) is redescribed on the basis of the lectotype (designated herein) and 69 non-type specimens from the eastern Indian and western Pacific oceans, ranging from the Andaman Sea east to New Caledonia, and northwestern Australia north to Japan. Literature records of the species from the Red Sea and Madagascar are considered applicable to Chelidoperca occipitalis Kotthaus 1973. Chelidoperca pleurospilus is characterized by the following combination of characters: pectoral-fin rays 14-16 (modally 15); pored lateral-line scales 40-43 (43); scale rows in longitudinal series 42-47 (44); scale rows between lateral line and base of 6th dorsal-fin spine 4 (3 full-sized scales plus 1 half-sized); interorbital scales reaching mid-orbit level, not extending beyond anterior margin of orbit; scales on lower jaw ventral surface restricted to angular, not extending anteriorly onto dentary; posterior tip of upper caudal-fin lobe slightly elongate with rounded or pointed contour, that of lower lobe not elongate, with rounded or truncate contour; longitudinal row of ca.

Three new species of Minous (Synanceiidae: Minoinae) are described. Minous roseus sp. nov.

Phylogeography of Lionfishes (Pterois) Indicate Taxonomic Over Splitting and Hybrid Origin of the Invasive Pterois volitans.

The lionfish is an iconic marine fish, and recently renowned for a disastrous introduction into the West Atlantic. Genetic surveys of the putative invaders (Pterois volitans and Pterois miles) in their natural Indo-Pacific range can illuminate both topics. Previous research indicated that P.

, a new species of pipefish (Syngnathidae) from southern Japan.

A new species of pipefish, Syngnathus chihiroe sp. nov., (Syngnathidae), is described on the basis of a single specimen collected off Yakushima Island (East China Sea), southern Japan in a depth of 160-162 m.

Chelidoperca stella, a new species of perchlet (Perciformes: Serranidae) from the Andaman Sea, eastern Indian Ocean.

A new species of serranid fish, Chelidoperca stella, is described on the basis of five specimens from the Andaman Sea in the eastern Indian Ocean. The species can be readily distinguished from all valid congeners by having fewer pored lateral-line scales (34 or 35 vs. 40-45 in the latter) and the pelvic fin white with several small yellow spots (vs.

Revision of the Indo-West Pacific genus Brachypterois (Scorpaenidae: Pteroinae), with description of a new species from northeastern Australia.

A taxonomic revision of the scorpaenid genus Brachypterois resulted in three valid species. Brachypterois serrulifer Fowler 1938, previously regarded as ajunior synonym of Sebastes serrulatus Richardson 1846, can be distinguished from its congeners by having usually 16 pectoral-fin rays (vs. 15 in the congeners) and 0-22 spines on the median lateral ridge of the maxilla (vs.
