3462395FAB07FF826688F8ADF9C3FD82.taxon	discussion	Remarks. Cedrosella is similar to Ambasiopsis, differing from it in the lack of a carina on antenna 1 peduncle article 1, the arrangement of the setal-teeth (modified 6 / 5 in Cedrosella and reduced to seven setal-teeth in Ambasiopsis) and the length of the gnathopod 1 carpus (shorter than propodus in Cedrosella, longer than the propodus in Ambasiopsis). This is the first record of this genus outside of the Cedros Trench, off Baja California, a considerable increase to its Pacific Ocean distribution. Cedrosella appears to have a lower bathyal to abyssal depth range (1840 – 3745 m).	en	Lowry, J. K., Kilgallen, N. M.

3462395FAB0EFF8C6688FF78FAC9FC6F.taxon	discussion	Remarks. According to Åse Wilhelmsen, ZMUO (2013 in litt.), only one sample of Lysianella petalocera from the G. O. Sars collection exists in the ZMUO in Oslo, with the locality “ N. m Finm. ” This sample is not registered in the type collection. “ N. m ” may mean Norvegia meridialis (Southern Norway) and “ Finm. ” may refer to Finmark, northern Norway. It is most likely Finmark, as L. petalocera has previously been collected from there at Mehavn, near Nordkap (G. O. Sars 1890) and therefore is not part of the type series.	en	Lowry, J.

3462395FAB0EFF8B6688FC19F9D6F9E4.taxon	discussion	Remarks. Lysianella lui is very similar to Lysianella mimica (J. L. Barnard, 1962). The most outstanding difference between these species is the maxilliped palp article 4 which is reduced and blunt in L. lui sp. nov., but well-developed in L. mimica. Lysianasella lui is also similar to L. morbihanensis (Bellan-Santini & Ledoyer, 1974) from the Kerguelen Islands, but the latter species apparently lacks a fourth article on the maxilliped palp, and the posteroventral lobe on pereopod 4 is not as strongly developed as in L. lui. Lysianella lui is the only species in the genus with no constriction on uropod 2, otherwise diagnostic for the genus. Depth range. 800 – 2450 m.	en	Lowry, J. K., Kilgallen, N. M.

3462395FAB16FF936688FE52F913F929.taxon	discussion	Remarks. The only other recognised species of Microlysias, M. xenokeras Stebbing, 1918, is known from south-western South Africa. A second species, M. indica K. H. Barnard, 1937, from the south Arabian coast is considered by Griffiths (1975) to be a synonym of M. xenokeras. Microlysias soela sp. nov. is very similar to M. xenokeras. The gnathopod 2 palm in M. xenokeras is extremely obtuse (almost at a right angle), but only moderately obtuse in M. soela and the antenna 2 peduncle article 3 is longer in the female of M. xenokeras. Microlysias soela also has a distinct spine-like projection from the apical margin of the maxilla 1 inner plate that is absent in M. xenokeras. Based on the less obtuse palm of gnathopod 2 the record of M. xenokeras from Pulau Tioman (Azman & Othman 2013) appears to be M. soela. Depth range. 41 – 120 m (this study).	en	Lowry, J.

3462395FAB11FF906688F8C4FD4BFC01.taxon	discussion	Remarks. The only character separating Paralysianopsis and Rhinolabia has been the well-developed apical robust setae on the palp of maxilla 1, present in Paralysianopsis (setae absent in Rhinolabia, but with a strong medially serrate margin). In P. pomona sp. nov. the medially serrate apical margin persists along with a set of lateral robust setae. In P. mazamoz the medial serrate margin is well developed and the robust setae are vestigial and in species such as P. paeowai there is only a remnant of the serrate medial margin and no robust setae. This is a gradational character which does not separate the genera. Paralysianopsis incerta (Ledoyer, 1986) was transferred to Glorieusella Kilgallen & Lowry, 2014.	en	Lowry, J. K., Kilgallen, N. M.

3462395FAB23FFAE6688FA96FA62FF31.taxon	discussion	Remarks. The genus appears to be most similar to Lepiduristes Barnard & Karaman, 1987, a monotypic genus known only from abyssal depths in the Caribbean Sea. These taxa are separated by the antenna 1 peduncle article 1 which is much more dorsally produced in Lepiduristes; the gnathopod 1 coxa, tapering in Lepiduristes but subrectangular in Patonga; the gnathopod 1 propodus which is much more elongate in Lepiduristes; and the uropod 3 which has an elongate second article on the outer ramus in Lepiduristes versus a short article in Patonga. Patonga is also very similar to Tryphosoides Schellenberg, 1931, but has a much longer antenna 1 accessory flagellum and lacks the characteristic offset accessory flagellum terminal article seen in Tryphosoides. Patonga differs from Cedrosella in having a non-tapering gnathopod 1 coxa and a much more poorly developed pereopod 4 basis posterior lobe.	en	Lowry, J. K., Kilgallen, N. M.

3462395FAB2FFFAD6688FD8CFB70FABE.taxon	discussion	Remarks. Tasmanosa gen. nov. is similar to Coximedon Barnard & Karaman, 1991, but does not display the broadened gnathopod 1 propodus characteristic of that genus. The setal-teeth are much more finely serrate and the robust setae on the medial margin of the maxilliped outer plate more strongly developed in Tasmanosa. Additionally, the gnathopod 1 propodus of Tasmanosa has a dense brush of long setae, while that of Coximedon only has sparse, short setae. Tasmanosa differs from Tryphosella Bonnier, 1893, in having a longer and more weakly tapering gnathopod 1 coxa with the carpus much shorter than the propodus, and the propodus densely setose on the posterior margin. Tasmanosa also has a longer and more weakly tapering gnathopod 1 coxa than Cedrosella Barnard & Karaman, 1987, in addition to having more finely serrate setal-teeth.	en	Lowry, J. K., Kilgallen, N. M.

3462395FAB3CFFBA6688FD14F95BFCF1.taxon	discussion	Remarks. Tryphosites psittacus sp. nov. differs from all other Tryphosites species by lacking the acutely produced epistome. Instead this species has an unusual epistome and upper lip complex in which the epistome is slightly produced in front of the upper lip and both are apically rounded. Depth range. 400 – 1264 m.	en	Lowry, J. K., Kilgallen, N. M. (2014): New tryphosine amphipods from Australian waters (Crustacea, Amphipoda, Lysianassoidea, Lysianassidae, Tryphosinae).
