本文是首次对热带澳大利亚的斑腿类两足类进行研究。在蜥蜴岛及其邻近珊瑚礁中，共记录到斑潜蝇科Cradocus、Dulichiella、Elasmopus、Maera、Mallaco ota和Parelasmopus属的17种。此外，在苍鹭岛上还记录到了哈瓦氏角叉尾轮虫。本文记述了7个新种：尖顶隐翅虫Cradocus oxodus、尖顶隐尾轮虫C.Wooree、杨氏隐尾轮虫C.yandala、尖顶轮虫Elasmopus crenulatus、尖顶轮尾轮虫E.spinicarpus、灰顶轮虫Maera Griffini和短尾轮虫Mallaco ota balara。建立并描述了猪拟毛虫的选型。对马拉科塔属的诊断进行了扩展，并包括了已知物种的检索表。在澳大利亚南部或东南部，还没有记录到蜥蜴岛和邻近珊瑚礁上的梅里提科。马达加斯加和毛里求斯拥有与蜥蜴岛地区相同的最多斑腿类物种。贝伦茨，P.B.，1983。澳大利亚大堡礁蜥蜴岛及其邻近珊瑚礁的梅里提科(甲壳纲：端足目)。澳大利亚博物馆纪录35(3)：101-143。大堡礁的Gammaridea以前没有被研究过。唯一出版的作品是K.H.巴纳德(1931)的作品，他报道了大英博物馆在1928-29年进行的大堡礁探险收集的端足类动物。他对11科14种进行了简要的报道，唯一的斑腿蜂科被鉴定为红斑大头鱼和Maera sp.J.L.Barnard(1976)强调，人们对热带端足类知之甚少，特别是与对该类群在寒冷温带水域的研究相比。最近，澳大利亚博物馆在大堡礁北部的蜥蜴岛地区开展了以小型无脊椎动物为重点的主要收藏方案。P.A.Hutchings博士和P.B.Berents博士对礁石群落进行了采样(H utchings和Weate，1977,1979)。J.K.Lowry博士和A.R.Jones博士进行了一次对藻类和软海底群落进行采样的考察。这些藏品是本研究的基础。本研究的目的是记录蜥蜴岛及其邻近珊瑚礁的斑腿类两足类的种类。描述了新种，对于已知的物种，比较了蜥蜴岛种群的形态和文献中描述的其他种群。比较了蜥蜴岛地区不同生境和不同地点的种类分布。蜥蜴岛的梅里蒂科与澳大利亚南部和印度-太平洋的梅里蒂科动物进行了比较。在蜥蜴岛和邻近的珊瑚礁进行了采样，这使得可以对高岛、珊瑚礁和外堡礁的边缘珊瑚礁进行采样(图1)。蜥蜴岛(14°40‘S，145°28’E)位于昆士兰海岸弗拉特里角东北18海里处。这是一个多岩石的高岛，周围环绕着珊瑚礁，这些礁石环绕着一个浅浅的泻湖，保护其免受盛行的3月至11月的东南风的影响。西北季风从12月到3月影响该地区。永格礁(14°36‘S，东经145°38’)位于蜥蜴岛东北10海里处。它是陆架边缘礁链的一部分，从墨累岛(9°58‘S)向南延伸至约16°S(Orme，1978)。这是一个尖顶带状珊瑚礁，由强流形成的珊瑚礁向后生长(Veron，1978)。珊瑚礁后面是一个类似泻湖的避难区，底部是沙子，散布着被称为珊瑚礁背部的炸弹。永日礁的外坡下降到40米，坡底有沙子和碎石。鹰岛(14°42‘S，145°23’E)位于蜥蜴岛东南5海里处的一个珊瑚礁。鹰岛周围的礁石长2海里，宽1.5海里。*现地址：澳大利亚堪培拉国立大学动物系，邮编：ACT 2600，澳大利亚
This paper is the first study of melitid amphipods from tropical Australia. Seventeen species of Melitidae in the genera Ceradocus, Dulichiella, Elasmopus, Maera, Mallacoota and Parelasmopus are recorded from Lizard Island and adjacent reefs. In addition Ceradocus hawaiensis Barnard is recorded from Heron Island. Seven new species are described: Ceradocus oxyodus, C. wooree, C. yandala, Elasmopus crenulatus, E. spinicarpus, Maera griffini and Mallacoota balara. A lectotype is established and described for Parelasmopus suensis. The diagnosis for the genus Mallacoota is expanded and a key to the known species included. None of the Melitidae from Lizard Island and adjacent reefs has been recorded from southern or south-eastern Australia. Madagascar and Mauritius have the highest number of melitid species in common with the Lizard Island area. BERENTS, P.B., 1983. The Melitidae of Lizard Island and adjacent reefs, the Great Barrier Reef, Australia (Crustacea:Amphipoda). Records of the Australian Museum 35(3): 101-143. The Gammaridea of the Great Barrier Reef have not been previously studied. The only published work is that of K.H. Barnard (1931) who reported on the Amphipoda collected by the Great Barrier Reef Expedition conducted by the British Museum in 1928-29. He reported briefly on 14 species from 11 families and the only Melitidae were identified as Ceradocus rubromaculatus and Maera sp. J.L. Barnard (1976) stressed that little is known of tropical Amphipoda, especially when compared with studies of the group in cold temperate waters. Recently major collecting programmes with the emphasis on small invertebrates have been carried out by the Australian Museum in the Lizard Island area on the northern Great Barrier Reef. Dr P.A. Hutchings and P. B. Berents sampled reef rock communities (H utchings and Weate, 1977, 1979). An expedition to sample algal and soft bottom communities was conducted by Dr J .K. Lowry and Dr A.R. Jones. These collections are the basis of this study. The aim of this study is to record the species of melitid amphipods from Lizard Island and adjacent reefs. New species are described, and for those species already known, the morphology of populations from Lizard Island is compared with other populations described in the literature. The distributions of the species among different habitats and localities in the Lizard Island area are compared. The Melitidae of Lizard Island are compared with melitid faunas from southern Australia and the Indo-Pacific. Sampling was carried out at Lizard Island and adjacent reefs, which allowed sampling of the fringing reefs of a high island, a coral cay and outer barrier reefs (Fig. 1). Lizard Island (l4°40'S, 145°28'E) lies 18 nautical miles north-east of Cape Flattery on the Queensland coast. It is a high rocky island surrounded by fringing reefs that enclose and protect a shallow lagoon from the prevailing south-east trade winds which blow from March to November. The north-west monsoon affects the region from December to March. Yonge Reef (l4°36'S, 145°38'E) lies 10 nautical miles north-east of Lizard Island. It is part of the chain of shelf edge reefs that follows the continental shelf from the Murray islands (9°58' S) south to approximately 16°S (Orme, 1978). It is a cuspate ribbon reef with a backward growth of reef formed by strong currents (Veron, 1978). Behind the reef is a sheltered lagoon-like area with a sandy bottom and scattered bommies known as the reef back. The outer slope at Yonge Reef drops to 40 metres with sand and rubble at the bottom of the slope. Eagle Islet (l4°42'S, 145°23'E) is a coral cay 5 nautical miles south-east of Lizard Island. The reef surrounding Eagle Islet is 2 nautical miles long and 1.5 nautical miles wide. *Present address: Zoology Department, Australian National University, Canberra, ACT 2600, Australia
