Marionina Michaelsen, 1889

49*. Marionina cana Marcus, 1965

Distr: BRA: SP: Cananéia ( Marcus 1965, p. 71). Rem: Brackish water species ( Römbke 2007, p.162).

50*. Marionina ecuadoriensis Righi, 1981

Distr: ECU: Los Tayos ( Righi 1981b, p. 236). Rem: Terrestrial species ( Römbke 2007, p. 163).

51*. Marionina exigua Ude, 1896

Distr: ARG: Tierra del Fuego: Ushuaia ( Ude 1896, p. 20). Rem: Marine species (Coates & Healy 2008).

52*. Marionina falclandica Michaelsen, 1905

Distr: off ARG: Falkland Islands ( Michaelsen 1905).

Rem: Marine species, labeled as incertae sedis (Coates & Healy 2008).

53. Marionina georgiana ( Michaelsen, 1888)

Other names for South America and correlated southern land masses: Pachydrilus georgianus Michaelsen, 1888 ; Christensenia georgiana ( Michaelsen, 1888) ; Christensenidrilus georgianus ( Michaelsen, 1888) .

Distr: Off southern ARG: Falkland Islands ( Baylis 1916, p. 288).

Furth. Distr: South Georgia Islands ( Stephenson 1932, p. 241) and Possession Island (Îles Crozet), southern Indian Ocean ( Michaelsen 1905, p. 15).

Rem: Although this species, from a political point of view, occurs in English territory, from a geographical perspective the species extends its range to the South American continental shelf ( Falkland Islands). Thus, biogeographically, it belongs both to the South American ( Falkland Islands) and to the subantarctic ( South Georgia Islands) domains. This species has recently been referred to again as Marionina georgiana ( Rota et al. 2008; Schmelz & Collado 2008).

54*. Marionina nea Marcus, 1965

Distr: BRA: SP: Cananéia ( Marcus 1965, p. 74). Rem: Brackish water species ( Römbke 2007, p. 162).

55*. Marionina patua Righi, Ayres and Bittencourt, 1978 Distr : BRA: AM: Manaus (Righi et al. 1978, p. 8). Rem: Terrestrial species ( Römbke 2007, p. 163).

56*. Marionina pituca Righi, 1974

Distr: MG: Serra do Cipó ( Righi, 1974b, p. 414); MT: Bataguassu, near Paraná river ( Righi 1981a, p. 428).

Rem: Terrestrial species ( Römbke 2007, p. 163).

57. Marionina riparia Bretscher, 1899

Distr: BOL: Amazon basin ( Martínez-Ansemil & Giani 1986, p. 114).

Furth. Distr: Europe and Africa ( Rota & Healy 1994, p. 65).

Rem: Listed as a marine species (Coates & Healy 2008), but this does not seem to be correct, according to Rüdiger Schmelz (pers. comm.). The material of Martínez-Ansemil and Giani (1986, p. 114) was found ¨in a small river¨. Römbke (2007, p. 162) does not include this species in his table of three species of the previous authors which he considers to represent ¨typical¨ terrestrial enchytraeids.

58*. Marionina schreiberi Righi, 1975

Distr: BRA: MG: Conceição do Mato Dentro Mun: Serra do Cipó ( Righi 1975, p. 148). Rem: Terrestrial species ( Römbke 2007, p. 163).

59*. Marionina subtilis ( Ude, 1896)

Other name for South America: Michaelsena subtilis Ude, 1896 .

Distr: ARG: south Patagonia: Dungeness point; Tierra Del Fuego: Ushuaia ( Ude 1896, p. 25). Rem: Possibly marine, labeled as species dubia (Coates & Healy 2008).
