03FE0E70FFA13275F1E4FB23FDFBFF5A.taxon	discussion	Remarks. The new family shares sensory setae on maxilla and maxilliped with a group of clausocalanoidean Bradfordian families including Diaixidae, Parkiidae, Phaennidae, Rostrocalanidae, Scolecitrichidae and Tharybidae. However, Kyphocalanidae is unique among all Bradfordians in possessing the following apomorphies: i) praecoxal arthrite of maxillule with 3 setae (vs usually 9 setae or more in other Bradfordians); ii) maxilla proximal coxal endite with 2 setae (vs 3 setae in other Bradfordians); iii) maxilla distal basal endite plus endopod with 8 very long and thick worm-like sensory setae longer than all remaining sclerotized setae of maxilla (vs 3 - 6 worm-like sensory setae of moderate length present in other Bradfordians, except the male of Kirnesius Markhaseva & Semenova, 2005 (whose family placement in Phaennidae is under review) bears 8 worm-like sensory setae of slender appearance shorter than sclerotized setae of maxilla); and iv) praecoxal lobes of maxilliped with a setal formula as 1,2,0 (vs 1,2,3; 1,2,2; 1,1,2; 1,2,1; 0,2,3; 0,2,2; 0,1,2; or 0,0,0 in other Bradfordians).	en	Markhaseva, Elena L., Schulz, Knud (2009): A new family and genus of calanoid copepods (Crustacea) from the abyss of the Atlantic Ocean.

03FE0E70FFA23274F1E4FE86FA28FE18.taxon	discussion	Remarks. Synapomorphies for the genus Kyphocalanus are the presence of a knife handle-like basal part of the proximal seta of the mandibular basis and the maxillule distal basal endite and endopod separate and the distal basal endite bearing 1 seta only (vs 2 – 6 setae in other Bradfordians). In addition to the characters of the family, the new genus differs from the majority of other Bradfordian families / genera by the following derived characters: i) antenna basis without setae, shared with tharybid genus Brodskius Markhaseva & Ferrari, 2005, contrasting the presence of 1 – 2 setae in other Bradfordians; ii) antenna endopod segment 1 without setae, shared with Pseudophaenna Sars, 1902 (genus of unclear familial position) and some species of the tharybid genus Undinella Sars, 1900, and contrary to 1 – 2 setae in other Bradfordians; iii) antenna endopod segment 2 with fewer than 10 setae, shared with Pseudophaenna, but this segment with 11 – 15 setae in other Bradfordians; iv) maxillule proximal basal endite without setae, shared with Bradfordiella Andronov, 2007 (genus of unclear familial position), in contrast to the presence of 2 – 5 setae in other Bradfordians; v) maxilla proximal praecoxal endite with 2 setae, shared with Rostrocalanus and some species of Bradfordiella, but with 3 – 5 setae in other Bradfordians; vi) maxilla distal praecoxal endite and proximal coxal endite with 2 setae each, shared with some species of Bradfordiella, and contrary to 3 setae in other Bradfordians; vii) maxilla distal coxal endite with 2 setae, shared with Phaenna Claus, 1863 (family Phaennidae), but with 3 setae in other Bradfordians; viii) maxilla proximal basal endite with 1 setal element, shared with Bradfordiella, but with 3 – 4 setal elements in other Bradfordians; ix) 1 seta on maxilliped coxal endite is shared with some species of Undinella and Bradfordiella, in contrast to presence of 2 or 3 setae in other Bradfordian genera. The similar derived armament of some oral limbs of Kyphocalanus gen. nov. and Bradfordiella is assumed to have arisen in a parallel development and independently, and thus both genera are not considered to be closely related. This is corroborated by apomorphies not shared by Bradfordiella: i) praecoxal arthrite of maxillule with 3 setae (vs 9 in Bradfordiella); ii) distal coxal endite of maxilla with 2 setae (vs 3 setae in Bradfordiella); iii) maxilla distal basal endite plus endopod with 8 very long and thick, worm-like sensory setae, longer than all sclerotized setae of maxilla (vs only 6 short sensory setae of unclear morphology (Andronov 2007: 632) in Bradfordiella). In addition, the new genus does not share apomorphies of Bradfordiella: i) antennule of only 18 articulated segments (vs 24 in Kyphocalanus); ii) mandibular basis lacking setae (viz. 2 setae in Kyphocalanus); iii) maxillule with coxal and basal endites reduced (vs these endites well developed in Kyphocalanus); v) maxilliped praecoxal endites of syncoxa lacking setae (with 1, 2, 0 setae in Kyphocalanus).	en	Markhaseva, Elena L., Schulz, Knud (2009): A new family and genus of calanoid copepods (Crustacea) from the abyss of the Atlantic Ocean.

03FE0E70FFAD327AF1E4FF23FC2EF99C.taxon	discussion	Remarks.

From all congeners it is distinct in that spinules are absent on the posterior surface of P 5; from Kyphocalanus sp. 1 it can be distinguished by the ratio of the lengths of P 5 exopodal spines. It shares with the type species the following characteristics that differentiate both from Kyphocalanus sp. 1: i) its larger size (2.10 – 2.24 mm vs 1.82 mm in Kyphocalanus sp. 1); ii) a longer endopod of antenna (ratio of exopod and endopod lengths as 1.8 vs 2.3 in Kyphocalanus sp. 1); iii) presence of 2 setae on maxilla proximal coxal endite (vs 1 seta); iv) and P 1 lateral spine of exopod segment 1 shorter than spines of exopod segments 2 and 3 (this spine is the longest in Kyphocalanus sp. 1).	en	Markhaseva, Elena L., Schulz, Knud (2009): A new family and genus of calanoid copepods (Crustacea) from the abyss of the Atlantic Ocean.
