7E0E87B8E5161145FF7FFCEF7E6B46F6.taxon	discussion	Remarks. Elasmopus ora resembles E. mcluerensis Hughes & Lowry, 2011 from the Australian Northern Territories. It differs markedly in the third uropod, which is relatively elongate and slender in E. ora but short and stout in E. mcluerensis. In addition, the telson shape is a little different in the two species and bears two setae on each side in E. ora but four setae on each side in E. mcluerensis. The uropod 3 is similar to that of E. gracilis Schellenberg, 1938, but in that species the posterior margin of the propodus in the male gnathopod 2 is clothed in dense long setae. Elasmopus pectenicrus Bate, 1862, has a similar shaped male gnathopod 2, but the propodus of that appendage is clothed in dense long setae on the posterior margin and the basis of pereopod 6 in that species is crenulate along the posterodistal margin. Habitat. Dead coral heads in shallow water.	en	Myers, A. A. (2014): Amphipoda (Crustacea) from the Chagos Archipelago. Zootaxa 3754 (1): 1-31, DOI: 10.11646/zootaxa.3754.1.1

Ampithoe hughesae resembles A. platycera Sivaprakasam (1970) but in that species the male gnathopod 1 palm is stepped whereas in A. hughesae it is evenly convex and male gnathopod 2 propodus posterior margin is truncate in A. platycera but produced forward into a strong " thumb " in A. hughesae. Other differences include the unflattened peduncular article 4 of antenna 2 in A. hughesae compared with the flatted peduncular article 4 in A, platycera (from which it derived its name). The male gnathopod 1 is also much more elongate in A. hughesae than it is in A. platycera. Habitat. In dead branching coral.	en	Myers, A. A. (2014): Amphipoda (Crustacea) from the Chagos Archipelago.

7E0E87B8E51E114EFF7FFBEB7E6B4385.taxon	discussion	Remarks. Latigammaropsis salomanensis sp. nov. is very similar to L. hermes Myers, 2009, from the Great Barrier Reef. It differs notably in the female. In L. salomanensis the propodus of gnathopod 2 has a strong acute spine defining the palm whereas in L. hermes, the palm of the appendage is defined by a small rounded protrusion. In addition, in the male, coxa 1 is more acute in L. salomanensis and the propodus of gnathopod 1 is more ovoid and the palm less oblique than in L. hermes. Habitat. Dead coral heads in shallow water.	en	Myers, A. A. (2014): Amphipoda (Crustacea) from the Chagos Archipelago. Zootaxa 3754 (1): 1-31, DOI: 10.11646/zootaxa.3754.1.1

7E0E87B8E5021151FF7FFF2F7F404532.taxon	discussion	Remarks. Present material is difficult to allocate since it shows a mixture of characters of L. bannwarthi Schellenberg, 1928 and L. gracilis. The gnathopod 2 has the posterior margin bare and the carpus tapered while the telson is less than 1.8 × its width. All these are features of L. bannwarthi. On the other hand, the dactylus of gnathopod 2 reaches over half the length of the propodus, coxa 4 is serrate on anterior and distal margins and telson is distally tridentate, all features of L. gracilis. For the present, due to the serrate coxa 4, this material is allocated to L. gracilis. This would be the first record of L. gracilis from the Indian Ocean. Habitat.

7E0E87B8E5061158FF7FF8DD7E6B434D.taxon	description	Description. Based on holotype, 3.0 mm. Head. Head ocular and subocular lobes rounded; eye renifom. Antenna 1 about one third body length; peduncular article 1 with distal spines; peduncular articles 2 and 3 short; flagellum with 15 articles. Antenna 2 broken. Maxilla 1 palp uniarticulate (probably two fused articles), not reaching extremity of outer plate. Labium outer plate distal margins concave; inner plate rudimentary. Maxilliped palp with three articles; article 2 with a distal extension almost reaching end of article 3. Pereon. Gnathopod 1 chelate; all articles slender. Gnathopod 2 similar to gnathopod 1 but subchelate. Pereopod 3 coxa scythiform; dactylus robust, two-thirds length of propodus. Pereopod 4 similar to pereopod 3 but coxa distal margin straight. Pereopod 5 coxa bilobed; basis posterior margin with proximal and mediodistal spines. Pereopod 6 coxa posterodistal margin weakly bifid; basis posterior margin with weak proximal spine and two mediodistal spines. Pereopod 7 coxa posterodistal margin with weak spine; basis posterior margin serrated with strong mediodistal spine. Pleon. Segments 1 – 3 each with paired dorsal spines. Epimeron 1 with strong sub-distal spine and weak distal spine. Epimera 2 – 3 each with strong sub-distal and distal spines. Uropods 1 – 2 rami subequal in length. Uropod 3 peduncle inner distal margin produced into a broad-based spine; inner ramus twice length of peduncle with two pectinate setae; outer ramus shorter than inner ramus. Telson emarginate with well developed distal spines.	en	Myers, A. A. (2014): Amphipoda (Crustacea) from the Chagos Archipelago. Zootaxa 3754 (1): 1-31, DOI: 10.11646/zootaxa.3754.1.1
7E0E87B8E5061158FF7FF8DD7E6B434D.taxon	discussion	Remarks. Iphimedia garciensis sp. nov is very close to I. grossimana Ledoyer, 1972 from Madagascar but differs in a number of ways. The head subocular lobe is rounded in I. garciensis but acute in I. grossimana. Maxilla 1 palp is one-articulate and short in I. garciensis but two-articulate and equal in length to the outer plate in I. grossimana. The telson has well-developed distal spines in I. garciensis but these are scarcely apparent in I. grossimana. Coxa 7 has a posterodistal spine in I. garciensis but lacks a spine in I. grossimana. There are also subtle differences in the spination of the pereopod 5 – 7 bases. In pereopod 7, for example, the basis of I grossimana has spines distal to the large mediodistal spine, but these are absent in I. garciensis. Habitat. Dead branching corals.	en	Myers, A. A.
