项目摘要

Triacanthodids are small, bottom dwelling fishes of the shelf and slope living 100 and 600 me depth, with most speciose found below 200m.Although Tyler (1968) published a monograph on the family Triacanthodidae, there still remain systematic problems in the Indo-west Pacific species. The purpose of this study is to revisec the Indo-west Pacific triacanthodis, putting emphasis on rarely collected species.The examination on the newly collected materials from New Caledonia and Australia showed that several specie (e.g., Triacanthodes intermedius and Paratriacanthodes retrospinis) are distributed east of Australia, where no triacanthodids have been reported except for Macrorhamphososdes uradoi. Examinations on many specimens kept at various museums showed that the following 13 species in the seven genera are found in the Indo-west pacific : Atrophacanthus japonicus ; Bathyphylax bombifrons, Halimochirurgus alcocki, Halimochirurgus centriscoides, Macrorhamphosodes platycheilus, Macrorhamphosodes uradoi ; Paratriacanthodes herrei, Paratriacanthodes retrospinis ; Triacanthodes anomalus, Triacanthodes ethiops, Triacanthodes indicus, Triacanthodes intermedius ; and Tydemania navigatoris.Bathphylax has been represented by two species, B.bombifrons Myers and B.omen Tyler, which are poorly known only from very few specimens. Examinations on many addtional speciments from Australia and New Caledonai led to a conclustion that B.omen is a junior synonym of B.bombifrons.

三棘目鱼类是生活在100米和600米深的陆架和斜坡底的小型鱼类，大多数特有种在200米以下。尽管泰勒(1968)发表了一本关于三棘目鱼科的专著，但印度-西太平洋物种仍然存在系统性问题。对新喀里多尼亚和澳大利亚新收集的资料进行了考察，发现在澳大利亚以东分布有几个种(如中间三棘目和反棘副棘目)，除乌拉多尼亚大棘目外，没有报道过三刺目。对保存在各博物馆的许多标本的检查表明，在印度-西太平洋发现了以下7属13种：Atroacanus Japan onicus；BathyPhylx ombillons，Halimochirurus cocki，Halimochirurus Centriscodes，Macrorhamphosodes Plycheilus，Macrorhamphosodes uradoi；Partriacanthodes herrei，Partriacanthodes Retriacanthois；Triacanthodes verarius，Triacanthodes ethiops，Triacanthodes indicus，Triacanthodes interacanthodes；以及Tydemania Navigator。通过对澳大利亚和新喀里多奈的许多标本的检验，得出结论：B.omen是B.ombirons的一个初级异名。
