03995134FF98FFC14916E8DEFBE0F98D.taxon	etymology	Etymology. A combination of the Latin word auster, meaning southern, with the Latin stem Maera. Species composition. Austromaera mastersii (Haswell, 1879 a).	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FF98FFC14916E8DEFBE0F98D.taxon	discussion	Remarks. Austromaera is part of the large Maera group, in which gnathopod 2 is symmetrical and significantly enlarged in males and females, the palms are acute with well defined corners and the rami of uropod 3 are distally acute or subacute. The main defining characters of the genus are: the weakly produced first article of the mandibular palp and the distally acute margins of the rami of the third uropods. Austromaera is the only member of the Maera complex with such strongly setose inner margins on the telson. It is excluded from Maera and Miramaera because of its ovate eyes, its short accessory flagellum and its weakly produced first mandibular palp article. It is excluded from Maera and Lupimaera because of its sparsely setose gnathopod 2 dactylus. Austromaera occurs in the Maera group, but appears to be most similar to the Indian Ocean species of Zygomaera that apparently have symmetrical second gnathopods. The main difference between these taxa is the telson that is emarginate in the Indian Ocean species. Currently Austromaera is confined to Australian waters.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FF98FFC14C51EC25FDB7F870.taxon	discussion	Lowry & Watson (2002) reviewed the discussion of informal groups within the Melitidae. They found a “ Maera-Elasmopus group ” and a “ Melita-Eriopisa ” group recognized by Bousfield (1977) and a “ Nuuanu group ” recognized by McKinney & Barnard (1977). Barnard & Barnard (1983) recognized a Ceradocus group (Maera-Elasmopus group of Bousfield, 1977), a Ceradocopsis group, an Eriopisa group, a Nuuana group (Nuuanu group of McKinney & Barnard, 1977), a Melita group (Melita-Eriopisa group of Bousfield, 1977) and a Parapherusa group. The Melitidae as conceived by Bousfield (1973) is not well defined and we can find no synapomorphy to define the whole group. In fact there appears to be very few widespread synapomorphies within the group. The extremely unequal rami of uropod 3 (the inner ramus is scale-like and the outer ramus is at least 3 × longer than wide) appears to be a synapomorphy that defines a Melita and an Eriopisa group. The Eriopisa group has an extremely well-developed second article on the outer ramus of uropod 3, another strong synapomorphy that separates this group from the Melita group. A third synapomorphy (two groups of small setae guarded by spines on the dorsum of urosomite 2) occurs throughout the Melita group and the Nuuana group, but not in the Eriopisa group. The Ceradocopsis, Ceradocus and Parapherusa groups all appear to be paraphyletic assemblages at best, with no defining synapomorphies. In this paper, for practical reasons, we recognize a Ceradocopsis group, a Ceradocus group (including Parapherusa), an Eriopisa group, a Nuuana group and a Melita group.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FF98FFC24E8FEE21FD6CF849.taxon	discussion	Remarks. Although there are many records of A. mastersii in the literature from inside and outside Australia, only Haswell (1879 a: 265, pl. 11, fig. 1), Sheard (1936: 177, fig. 3), J. L. Barnard (1972 a: 226, fig. 132), J. L. Barnard, 1972 b: 109, figs 55 – 56 and Ledoyer (1979: 77, fig. 44) illustrated their material. Neither Sheard (1936), nor J. L. Barnard (1972 a, b) showed the distinctive third uropods and telson illustrated by Haswell (1879 a). Their misidentified species have recently been studied by Krapp-Schickel (2003). The material of Ledoyer (1979) was later shown to be a different species, now known as Zygomaera pseudemarginata (Ledoyer, 1982). Based on currently available information, A. mastersii appears to be confined to southeastern and possibly southern Australia. Other records attributed to this species (at least since Haswell [1885] synonymized L. thomsoni with A. mastersii and certainly since the illustrations of Sheard [1936]) represent Linguimaera leo and L. tias of Krapp-Schickel (2003) plus several unknown species.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FF9BFFCC4ECFEE5AFACFFC78.taxon	discussion	Remarks. Among Australian species of Ceradocus, C. circe occurs in the group with sparse serrations along the posterior margins of epimera 1 and 2. Within this group C. circe appears to be the only species with the rami of uropod 3 more than twice as long as the peduncle (not known for C. yandala Berents, 1983 from tropical northeastern Australia). Ceradocus orchestiipes A. Costa, 1853 from the Mediterranean Sea, has sparse serrations along the posterior margins of epimera 1 and 2, long rami on uropod 3 and the second gnathopods in the male and the female are very similar to those of C. circe. But C. orchestiipes does not have dorsal serrations on urosomites 1 – 3, nor does it have a strongly serrate posterodistal corner on epimeron 3.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FF90FFCA4EA6EC96FACFFE91.taxon	discussion	Remarks. Since Haswell (1879 b) described Linguimaera hamigera (as Maera hamigera) from Port Jackson, only Stebbing (1910 a) has reported it from Australian waters — several specimens of about 5 mm length from off Wattamolla, which he unfortunately did not illustrate. However, it has been reported by Walker (1909) from the Red Sea, K. H. Barnard (1916) from Southern Africa, J. L. Barnard (1965) from Micronesia, Karaman & Ruffo (1971) from the Mediterranean Sea, Myers (1997) from Western Samoa and Ledoyer (1982) from Madagascar. Ledoyer (1982) completely illustrated and described his material. Based on this species concept he suggested that the Maera sp. A of J. L. Barnard, 1970, is also L. hamigera, extending its distribution to Hawaii and that L. mannarensis (Sivaprakasam, 1970) is a synonym of L. hamigera, thus extending its distribution into India, a proposition not accepted by Krapp-Schickel (2003). All reports subsequent to Stebbing (1910 a) must be considered as erroneous. As currently known, A. hamigera is confined to southeastern Australia. Illustrated species in the literature (Walker, 1909; K. H. Barnard, 1916; J. L. Barnard, 1965; Karaman & Ruffo, 1971; Ledoyer, 1982) refer to one or more unnamed species. For instance Karaman & Ruffo (1971) illustrated a cleft telson without setae on the inner margins, whereas Ledoyer’s (1982) specimens have well-developed robust setae along the inner margins. Linguimaera hamigera is most similar to L. boecki, but easily distinguished from that species by its cleft telson.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

It has a large posteroventral spine on epimeron 3, like M. subcarinata and M. diemenensis. Mallacoota euroka differs from M. diemenensis in having no dorsal spines on pleonites 1 to 3. It differs from M. subcarinata in the number of robust setae on the first peduncular article of antenna 1 (five in M. euroka and one to three in M. subcarinata), in having posteroventral notches on coxae 1 and 2 and in having a convex posterior margin on the basis of pereopod 7.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FF80FFDB4EEFEB5EFD5BF9C9.taxon	discussion	Remarks. Mallacoota malua is most closely related to Mallacoota kameruka. They differ in the shape of the bases of pereopods 5 – 7, and in the sculpturing on the palm of gnathopod 2. Mallacoota malua is the only species with posterodistal hood-like projections on pereopods 6 and 7.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FFBCFFE64C01E8F9FACFF90B.taxon	discussion	Remarks. Mallacoota subcarinata Haswell, 1879 b appears to be confined to Australian waters. All extrinsic records need to be carefully studied. The species appears to be most similar to those species with a strong posteroventral corner spine on epimeron 3. In Australian waters this includes M. diemenensis and Mallacoota euroka. Mallacoota diemenensis differs from all other Australian species in having dorsal carinae on pleonites 1 to 3. Mallacoota subcarinata differs from Mallacoota euroka in having only one to three robust setae along the posterior margin of antennal peduncular article 1 and in the posterior margin of the basis of pereopod 7 that is straight in M. subcarinata and convex in M. euroka.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FFBFFFE04EF3EED8FDB0FE5F.taxon	etymology	Etymology.

03995134FFBFFFE04EF3EED8FDB0FE5F.taxon	discussion	Remarks. Miramaera is excluded from the Linguimaera group because of its symmetrical second gnathopods. It is excluded from Quadrimaera because of the strong apical notch on the anteroventral margin of the head, the acute palms on the propodi of male gnathopod 2, the simple dactyli on pereopods 5 – 7 and the telsonic lobes that are truncated with apical cusps. It may be most similar to genera in the Maera group (sensu stricto), but it differs from that group in the setation of the dactyli of the second gnathopods. The significant differences between Miramaera and Lupimaera are that in Miramaera the posterior margin of epimeron 3 is smooth, the rami of uropod 3 are longer than the peduncle and the telsonic lobes have apical cusps and short robust setae. Miramaera differs from Maeropsis in having acute palms and a well defined corner of more than 90 ° on both male and female propodi of gnathopod 2.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FFBBFFED4DE2EF72FA3AFB2D.taxon	discussion	Remarks. This species fits Parelasmopus because of the highly distinctive mandibular palp with its very long first article and very short second article, but it differs from the generic definition in not having a serrate posteroventral margin on epimeron 3, nor does it have dorsally bicarinate first and second pleonites. J. L. Barnard (1972 a) established Ifalukia for one species of Parelasmopus that lacked dorsal carinae on the pleonites and urosomites, and lacked posteroventral serrations on epimeron 3. Parelasmopus sowpigensis is most similar to Ifalukia, but differs in having a dorsally bicarinate first urosomite. It therefore strictly fits neither genus. If the mandibular palp is the main synapomorphy defining Parelasmopus, then it appears that some species in the complex have either lost or never had dorsal carinae or serrate ventral margins. Until the phylogenetic implications of these questions can be analysed it is best to maintain a broad concept of the genus. Parelasmopus sowpigensis is therefore a distinctive species differing from other Australian species in having dorsally smooth first and second pleonites and smooth ventral margins on epimeron 3.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

It is most similar to Q. bengalensis Stebbing, 1907, in having robust setae on the inner margins of the telson. Quadrivisio sarina differs from that species in the shape of the basis of pereopod 7 and in the shape of the palm of gnathopod 2. The antennae and rami of uropod 3 are generally less setose in Quadrivisio sarina.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

Consequently another specimen from near the type locality (AM P 56684) was illustrated and used for the description. Since then the type specimen has been located. Victoriopisa australiensis and V. marina differ most obviously from each other as follows. In V. australiensis the male gnathopod 2 has a short carpus and the palm of the propodus is broadly excavate and not bordered by robust setae, whereas in V. marina the carpus is compressed and the palm is narrowly excavate and bordered by robust setae. Victoriopisa australiensis has a large, broadly expanded basis and merus on pereopod 7 with many slender setae distally. In V. marina the basis and merus are narrower and the distal part of the pereopod is not nearly as setose.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FFADFFF34EB9EDA2FAB8F85C.taxon	discussion	Remarks. There are at least two distinctive species of Dulichiella along the east coast of Australia. Their ranges overlap along the Great Barrier Reef. Dulichiella australis and D. pacifica are easily distinguished by the spines on the distolateral margin of male gnathopod 2. In D. australis there are 3 rounded, rather indistinct spines and in D. pacifica there are 4 acute distinct spines. In addition pereopods 6 and 7 are more setose in D. australis.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).

03995134FFA5FFFB4ECAEE6EFCB2F84E.taxon	discussion	Remarks. Melita ophiocola is an unusual and distinctive species of the genus. It is an obligate commensal of the brittle star Ophionereis schayeri (Muller & Troschel). Preliminary results of experimental data indicate that the largest adult amphipods tend to occur in heterosexual pairs on the host and occasionally more than one pair may occur. Over 80 % of individuals sampled were juveniles and there can be as many as 50 young per host. Juveniles occur throughout the year. Mate selection experiments involving live animals showed that a significant number of large adults initially released on an overcrowded host move to another host and form heterosexual pairs (Peter Castro, pers. comm.). This apparent mobility may explain the high infection rates of over 90 % observed in the field. In a highly unusual situation for species of Melita, there is virtually no sexual dimorphism between males and females. We assume that this is because the female and male are always present together on the host and so there is no need for precopulatory amplexus and its associated morphological modifications. Ophionereis schayeri is found in shallow water beneath large rocks and in crevices. It is more active at night when it may forage in the open. It moves by sinuous flexing of its arms and feeds on detritus that is transported to the mouth by the tube feet. It is assumed that M. ophiocola feeds on the detritus collected by its host. Melita ophiocola has a banded colour pattern of purple and cream dorsally with purple gnathopods and pereopods tending to cream distally. This is similar to the colour pattern of the aboral surface of its host. Melita ophiocola is able to move freely over the body and arms of the brittle star but lives mostly on the oral surface of the arms between the two rows of tube feet.	en	Lowry, JK, Springthorpe, RT (2005): New and Little-known Melitid Amphipods from Australian Waters (Crustacea: Amphipoda: Melitidae).
