Key to genera of Archinominae Kudenov, 1991 View in CoL

(modif. Fauchald 1977a)

1 Notopodia with single dorsal cirri (cirrophore well-defined)... ................................................. 2

– Notopodia with ‘two dorsal cirri’ (one with cirrophore well-defined, the other is a cirriform branchia), at least along a few anterior chaetigers.................................................................................... 4

2(1) Caruncular lateral plates barely developed; first branchiae from chaetiger 2, all branching; notochaetae all furcates, harpoonchaetae missing............................................................... .. Archinome Kudenov, 1991 View in CoL

– Caruncular lateral plates distinct; first complex branchiae from chaetiger 3–5, anterior chaetigers with cirriform branchiae; complex branchiae mostly bipinnate; notochaetae include harpoon furcates with denticles along outer margin............ 3

3(2) Bipinnate branchiae from chaetiger 5, first pair markedly larger than following ones; neurochaetae furcates, major tines with denticles along inner margin; eyes absent.............................................. Bathychloeia Horst, 1910 View in CoL

– Bipinnate branchiae from chaetiger 4 or 5, progressively smaller along posterior region; neurochaetae usually furcates, major tines smooth, rarely with small spurs, or without them (acicular chaetae); eyes present...................................................................................................... Chloeia Savigny View in CoL in Lamarck, 1818

4(1) Caruncle with high central ridge, lateral plates wide.......................................................... 5

– Caruncular lateral plates small, hidden under central ridge, or absent. ............................................ 6

5(4) Branchiae of similar size along body, or decreasing posteriorly.............................. Notopygos Grube, 1855 View in CoL

– First branchiae markedly larger than following ones............................... Bathynotopygos Kucheruk, 1981 View in CoL

6(4) Caruncle wedge-shaped, annulated, without crest and folds; notochaetae harpoon furcates with denticles along a short inner distal margin...................................................................... .. Sangiria Horst, 1911 View in CoL

– Caruncle with crest and folds........................................................................... 7

7(6) Caruncle high, loosely plaited and rugose; notochaetae include harpoon furcates with denticles along outer or inner margins............................................................................. Chloenopsis Fauchald, 1977 View in CoL

– Caruncle low, narrowly plaited with a crenulated plate; notochaetae include harpoon furcates with denticles along a short inner distal margin..................................................................... Parachloeia Horst, 1912 View in CoL
