约翰逊，J.W.2006。产于澳大利亚东北部的Parapercis二新种(Perciformes：Pguipedidae)和重新发现的Parapercis colemani Randall&Francis，1993。维多利亚博物馆回忆录63(1)：47-56。本文记述了两个新种--褐斑潜蝇(Parapercis Fl Avolabiata)和性吸虫(P.exlorata)。前者是从澳大利亚大堡礁(Anzac Reef)和马斯格雷夫岛女神岛(Lady MusGrave Island)之间，由底栖雪橇和底拖网采集的20个标本中已知的。它在外观上最类似于Parapercis Multiicata Randall，1984和P.Colemani Randall&Francis，1993，但在该属中是独一无二的，具有背射线V，21，肛射线I，17-18，侧线鳞片51-55，Palatine Edentate，产生的带小刺的副脊骨角度，9-10和20个尾椎，着色包括6个横跨背部的红色鞍状物鼻部周围每个眼眶的前缘都有一条紫红色的线条，头部和脊椎的后眼眶部分有一系列黄边的红点。在澳大利亚东部中部、昆士兰州莫雷顿角和新南威尔士州北孤岛之间、距离86-137米的水域中，从7个标本中描述了六齿拟副金枪鱼，它与其最接近的具有腭齿和黑色横杆的同类很容易区分，它们分别是：巨噬拟青虫Pietschmann(1911)和田中副金鱼(P.Muronis Tanaka，1918)，它们有四根而不是平直的背鳍刺和六根而不是平直的横杠。Parapercis colemani Randall&Francis，1993以前仅从诺福克岛泻湖1.5m深处采集的正型标本中被发现。在塔斯曼海的NORFANZ调查中收集的其他标本表明，该物种通常生活在更深的栖息地，出现在更广泛的地理区域。对于额外的材料，报告了新的地点和合并数据。
Johnson, J.W. 2006. Two new species of Parapercis (Perciformes: Pinguipedidae) from north-eastern Australia, and rediscovery of Parapercis colemani Randall & Francis, 1993. Memoirs of Museum Victoria 63(1): 47–56. Two new species of pinguipedid fi shes, Parapercis fl avolabiata and P. sexlorata, are described. The former is known from 20 specimens collected by epibenthic sled and demersal trawl from within the Great Barrier Reef, Australia, between Anzac Reefs and Lady Musgrave Island, in depths from 45 to 79 m. It is most similar to Parapercis multiplicata Randall, 1984 and P. colemani Randall & Francis, 1993 in appearance, but is unique among the genus in having a combination of dorsal rays V, 21, anal rays I, 17–18, lateral-line scales 51–55, palatines edentate, angle of subopercle produced and with small spinules, 9–10 abdominal and 20 caudal vertebrae, and colouration including six broad red saddles across the back, a purplish-red line from the anterior edge of each orbit around the snout, and a series of yellow-edged red spots on the postorbital part of the head and nape. Parapercis sexlorata is described from seven specimens trawled off central eastern Australia between Cape Moreton, Queensland and North Solitary Island, New South Wales in 86 to 137 m. It is easily distinguished from its closest congeners with palatine teeth and dark transverse bars, P. macrophthalma Pietschmann, 1911 and P. muronis Tanaka, 1918, by having four rather than fi ve dorsal-fi n spines and six rather than fi ve transverse bars. Parapercis colemani Randall & Francis, 1993 was previously known only from the holotype, collected in 1.5 m depth in the lagoon of Norfolk Island. Additional specimens collected on the NORFANZ survey in the Tasman Sea indicate that the species usually inhabits much deeper habitats and occurs over a wider geographic area. New localities and meristic data are reported for the additional material.
