本文描述了产于澳大利亚东部亚热带沿海沃茨的两种单海葵。从昆士兰州Capricorn-Bunker群内拖网捕获的7个标本中描述了一个新的属和种-拟扁头鱼Pseudopataecus taenianotus。它与其他单棘亚目的区别在于头部和身体明显压缩，大量的背鳍和臀鳍条，额骨有横向弯曲的脊形成一个浅的肉质凹陷，以及第一背棘明显的前插入。描述了采自昆士兰州南部和新南威尔士州北方近海沃茨的三个标本中的一个新种-小椰子属Cocotropus microps。牠们的背鳍和臀鳍鳍条数是该属中最少的，背鳍形成三个隆起的部分，颜色包括至少几个小的苍白不规则斑点或较大的斑点。澳大利亚沃茨首次记录到两种单辐鱼。Acanthosphex leurynnis Jordan &西尔，1905，以前已知分布于香港、泰国湾、印度东南部、印度尼西亚和巴布亚新几内亚东部，现报道分布于澳大利亚热带东部的坎伯兰群、阿拉弗拉海、北领地和西澳大利亚珀斯附近。Xenaploactis cautes Poss & Rummeyer，1980，以前只在安达曼海和泰国湾发现，现在在澳大利亚西北部丹皮尔和昆士兰州卡奔塔利亚湾发现。
Two new species of aploactinids are described from coastal waters of subtropical eastern Australia. Pseudopataecus taenianotus, new genus and species, is described from seven specimens trawled inside the Capricorn-Bunker Group, Queensland. It is readily distinguished from other aploactinids by the markedly compressed head and body, large number of dorsal and anal-fin ray elements, frontal bone with laterally-bowed ridges forming a shallow fleshy depression, and distinctly anterior insertion of the first dorsal spine. Cocotropus microps, new species, is described from three specimens collected from inshore waters of southern Queensland and northern New South Wales. It has the lowest dorsal- and anal-fin ray counts of the genus, dorsal fin forming three elevated sections, and coloration including at least several small pale irregular spots or larger blotches. Two aploactinid species are recorded in Australian waters for the first time. Acanthosphex leurynnis Jordan & Seale, 1905, previously known from Hong Kong, Gulf of Thailand, southeast India, Indonesia and eastern Papua New Guinea, is reported from the Cumberland Group in tropical eastern Australia, Arafura Sea, Northern Territory, and near Perth, Western Australia. Xenaploactis cautes Poss & Eschmeyer, 1980, previously known only from the Andaman Sea and Gulf of Thailand, is reported from off Dampier, northwestern Australia and Gulf of Carpentaria, Queensland.
