Systematic Revision of Indo-west Pacific Triacanthodidae

三棘目是小型的，生活在100和600米深的陆架和斜坡上的底栖鱼类，大多数物种在200米以下被发现。尽管Tyler（1968）发表了关于Triacanthodidae科的专著，但在印度-西太平洋物种中仍然存在系统问题。本研究的目的是修订印度-西太平洋三棘虫，重点是很少收集的物种。对新喀里多尼和澳大利亚新收集的材料的检验表明，几个种（如Triacanthodes intermedius和Paratriacanthodes retrospinis）分布在澳大利亚东部，除了Macrorhamphososdes uradoi外，没有报道过triacanthoids。对各博物馆保存的许多标本的检查表明，在印度-西太平洋发现的7属中有以下13种：Atrophacanthus japonicus；长叶大叶藻、长叶大叶藻、长叶大叶藻、长叶大叶藻；右肋旁棘，后棘旁棘；异常三棘、黑三棘、indicus三棘、中间三棘；和Tydemania navigatoris。Bathphylax有两个物种代表，b.b umifrons Myers和b.m omen Tyler，仅从极少数标本中鲜为人知。对来自澳大利亚和新喀里多奈的许多其他标本的检查得出结论，b.m omen是b.b bombifrons的初级同义词。

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.
