DF2387A4E405C320FF2DFC2FFD21A3E4.taxon	diagnosis	Diagnosis: Antenna 1 with a continuous band of setae on terminal article; antenna 2 longer than terminal article of antenna 1. Lacinia mobilis of right mandible with teeth; maxilliped inner lobes rounded. Accessory gills present, usually sausage shaped or subtriangular, large; spinelike process present on the base of lateral gills. Type species: Isocyamus delphinii (Guérin-Méneville, 1836). Remarks: Isocyamus is found in multiple host taxa. Isocyamus delphinii is the most widespread species, found in various delphinids, including the orca O. orca and bottlenose dolphin T. truncatus (Wardle et al., 2003). Isocyamus indopacetus Iwasa-Arai & Serejo, 2017 is found on the Longman’s beaked whale I. pacificus, one of the least studied cetaceans (Iwasa-Arai et al., 2017). Species: Isocyamus delphinii (Guérin-Méneville, 1836), I. antarcticensis Vlasova, 1982, I. deltobrachium Sedlak-Weinstein, 1992, I. kogiae Sedlak-Weinstein, 1992, I. indopacetus Iwasa-Arai & Serejo, 2017.	en	Iwasa-Arai, Tammy, Serejo, Cristiana Silveira (2018): Phylogenetic analysis of the family Cyamidae (Crustacea: Amphipoda): a review based on morphological characters.

DF2387A4E405C32FFC53FAEEFE62A5D5.taxon	diagnosis	Diagnosis: Antenna 1, short, four-articulated, without setal arrangement on terminal article. Antenna 2 small, three-articulated. Maxilliped without palps. Gnathopod 1 palm very short, vertical, dactyli very recurved; gnathopod 2 palm short, subequal in length to gnathopod 1. Lateral gills short, subtriangular; accessory gills absent. Dactyli of Per 5 – Per 7 very curved. Type species: Platycyamus thompsoni (Gosse, 1855). Remarks: Platycyamus is recognized as a genus ectoparasitic of beaked whales; it was previously believed that only beaked whales host this genus. However, in more recent studies ziphiid whales have been shown to host Platycyamus, Isocyamus and Cyamus. Species: Platycyamus thompsoni (Gosse, 1855), P. flaviscutatus Waller, 1989.	en	Iwasa-Arai, Tammy, Serejo, Cristiana Silveira (2018): Phylogenetic analysis of the family Cyamidae (Crustacea: Amphipoda): a review based on morphological characters.

DF2387A4E40AC32FFC2CFDDEFADBA264.taxon	diagnosis	Diagnosis: Incisor of left mandible with six teeth, right incisor with seven teeth; lower lips inner lobes fully fused. Palm of gnathopod 1 with a broad proximal expansion. Pereonites 3 and 4 narrower than pereonite 5 in males and subequal in width in females. Pereonite 4 of male without posterolateral knoblike process. Accessory gills spinelike in males and absent in females. Type species: Cyamus balaenopterae (KH Barnard, 1931). Etymology: The specific epithet refers to the hosts associated with this genus, the family Balaenopteridae Gray, 1864. Remarks: In contrast to Cyamus species, which are usually host specific, Balaenocyamus gen. nov. is more widespread and is found on large baleen whales of the family Balaenopteridae, such as Balaenoptera musculus, B. physallus and B. acutorostrata. Balaenocyamus gen. nov. differs from Cyamus, by: (1) incisor with six teeth (vs. five teeth); (2) lower lip inner lobes fully fused (vs. partly fused); (3) pereonites 3 and 4 narrower than pereonite 5 in males and subequal in width in females (vs. pereonites 3 and 4 wider or subequal in width to pereonite 5 in males and wider in females); (4) accessory gills spinelike in males and absent in females (vs. accessory gills usually bilobed in males and usually present in females); and (5) pereonite 4 of male straight, without posterolateral knoblike process (vs. pereonite 4 of male with a posterolateral knoblike process). Haney (1999) also found B. balaenopterae comb. nov. to be a basal group of Cyamus and commented on its plesiomorphic character states, suggesting B. balaenopterae comb. nov. to be an intermediate between Cyamidae and Caprellidae, according to its general morphology. Although the position of B. balaenopterae within Mysticyaminae subfam. nov. has low statistical support (clade 3), the subfamily was recovered in all analyses, and most of the representatives of Mysticyaminae subfam. nov. are found parasitizing mysticetes.	en	Iwasa-Arai, Tammy, Serejo, Cristiana Silveira (2018): Phylogenetic analysis of the family Cyamidae (Crustacea: Amphipoda): a review based on morphological characters.

DF2387A4E40AC32FFEA7F9D7FC2BA4DC.taxon	diagnosis	Diagnosis: Body usually large. Antenna 1 with multiple grouping of setae on terminal article; antenna 2 with four articles. Lacinia mobilis multituberculate with variation in the number of teeth. Lower lip with inner lobes partly fused (except B. balaenopterae). Lateral gills elongate. Accessory gills of male always present. Accessory gills of female usually present. Genital valve anterior margin setose. Carpus of pereopods usually with a process on posterior margin. Dactyli of pereopods slightly curved. Type genus: Cyamus Latreille, 1796. Remarks: This subfamily was erected based on the synapomorphies of Balaenocyamus gen. nov. and Cyamus, which were previously considered to be a single genus. Species of this subfamily are generally larger, host specific, and parasitize baleen whales and large odontocetes of the families Monodontidae, Ziphiidae and Physeteridae. Genera: Cyamus Latreille, 1796, Balaenocyamus gen. nov.	en	Iwasa-Arai, Tammy, Serejo, Cristiana Silveira (2018): Phylogenetic analysis of the family Cyamidae (Crustacea: Amphipoda): a review based on morphological characters.

DF2387A4E40AC32FFF0DFEF5FDEEA692.taxon	diagnosis	Diagnosis: Body small, stout. Antenna 1 very reduced, two-articulated; antenna 2 minute, one-articulated. Gnathopod 1 simple, palm straight; gnathopod 2 without palm, with a particular crevisse bearing a spine. Pereonites 3 and 4 very short; lateral gills uniramous; accessory gills lacking. Oostegite plates boot shaped. Type species: Scutocyamus parvus Lincoln & Hurley, 1974. Remarks: Scutocyamus is a genus of small, temperate water dolphins, and its distribution is largely unknown. Scutocyamus parvus was reported from the white-beaked dolphin Lagenorhynchus albirostris from the North Sea, and later on, S. antipodensis was described from Hector’s dolphins Cephalorhynchus hectori from New Zealand. Species: Scutocyamus parvus Lincoln & Hurley, 1974; S. antipodensis Lincoln & Hurley, 1980.	en	Iwasa-Arai, Tammy, Serejo, Cristiana Silveira (2018): Phylogenetic analysis of the family Cyamidae (Crustacea: Amphipoda): a review based on morphological characters.

Pereonites 3 and 4 wider or subequal in width to pereonite 5 in males and wider in females. Pereonite 4 of male with a posterolateral knoblike process. Accessory gills of female usually present, oval. Type species: Cyamus ceti (Linnaeus, 1758). Remarks: Most species of Cyamus are host specific, and some whales can host more than one Cyamus species. It is the largest genus and is the most studied, owing to commercial whaling of and large amounts of parasites on slow-moving cetaceans. Species: Cyamus ceti (Linnaeus, 1758), C. boopis L ü t k e n, 1 8 7 0, C. c a t o d o n t i s M a r g o l i s, 1 9 5 4, C. erraticus Roussel de Vauzème, 1834, C. eschrichtii Margolis, McDonald & Boulsfield, 2000, C. gracilis Roussel de Vauzème, 1834, C. kessleri A Brandt, 1873, C. mesorubraedon Margolis, McDonald & Boulsfield, 2000, C. monodontis Lütken, 1870, C. nodosus Lütken, 1860, C. ovalis Roussel de Vauzème, 1834 and C. scammoni Dall, 1872.	en	Iwasa-Arai, Tammy, Serejo, Cristiana Silveira (2018): Phylogenetic analysis of the family Cyamidae (Crustacea: Amphipoda): a review based on morphological characters.
