Brood pouch evolution in pipefish and seahorse based on histological observation.

Introduction: Fishes of the Syngnathidae family are rare in having male pregnancy: males receive eggs from females and egg development occurs in the male brood pouch that diverged during evolution. The family is divided into two subfamilies: Nerophinae and Syngnathinae.

Methods: We compared histologically five types of the brood pouch in Syngnathinae: an open pouch without skinfolds (alligator pipefish); an open pouch with skinfolds (messmate pipefish); a closed pouch with skinfolds (seaweed pipefish); and closed pouches with a sac-like pouch on the tail (pot-bellied seahorse) or within a body cavity (Japanese pygmy seahorse).

Review of the Lepadichthys lineatus complex (Gobiesocidae: Diademichthyinae) with descriptions of three new species.

The Lepadichthys lineatus complex (Gobiesocidae: Diademichthyinae) is defined by three unique characters within Lepadichthys: (a) upper-jaw lip fused with snout skin, usually lacking a distinct groove between the dorsal lip margin and snout (if present, very weak, restricted to posterior portion of jaw); (b) snout tip well extended, distinctly beyond lower-jaw tip; and (c) inner surface of both lips with oral papillae.

Three new goatfishes of the genus Upeneus from the Eastern Indian Ocean and Western Pacific, with an updated taxonomic account for U. itoui (Mullidae: japonicus-species group).

Review of the waspfish genus (Tetrarogidae), with a key to genera in the family.

A taxonomic review of the waspfish genus Matsubara 1943 (Tetrarogidae), diagnosed by the following combination of characters: body sparsely covered with small embedded cycloid scales, palatine teeth present, XIII-XVI dorsal-fin spines, the first dorsal fin originating above the orbit, five pelvic-fin soft rays, and membrane of lower four pectoral-fin rays deeply incised, resulted in the recognition of six species: (Weber 1913), (Lloyd 1909a), Matsubara 1943, Klausewitz 1985, (Smith 1958), and Chan 1966. (anti-tropically distributed in East Asia and Australia) can be distinguished from its congeners by the presence of three dark blotches on the body (vs. absent or a single blotch); (eastern Indian Ocean) and (Philippines to Australia) differ from other congeners in having a black blotch behind the opercle (vs.
