Nuclearia

Nuclearia is a genus of nucleariid amoebae with filose pseudopodia and discoid mitochondrial cristae.
Nominal species treated as members of the genus include:Astrodisculus affinis Schouteden 1905Astrodisculus araneiformis Schewiakoff 1893Astrodisculus laciniatus Penard 1904 Astrodisculus marinus Kufferath 1952Astrodisculus minutus Greeff 1869Heliophrys variabilisNuclearina similisN. amphizonellae Penard 1917N. conspicua West 1903Nuclearia delicatula Cienkowsky 1865N. lohmanni Kufferath 1952N. pseudotenelloidesN. flavescens Patterson 1984 N. flavocapsulata Patterson 1984 N. leuckarti Patterson 1984 N. moebiusi Frenzel 1897N. pattersoni Dyková et al. 2003N. polypodia Schewiakoff 1863N. radians Patterson 1984 N. simplex Cienkowsky 1865 N. thermophila Yoshida, Nakayama & Inouye 2009N. rubra Patterson 1984
The type species is Nuclearia delicatula, which may adopt a spherical or a flattened body form.
There is considerable uncertainty as to the identity of species and genera, and this led to the inclusion in Nuclearia of taxa previously assigned to Astrodisculus, Nuclearella, Nuclearina, Heliosphaerium and Nucleosphaerium, and the diversity rendered to 9 clearly distinguishable species with the affinities of Astrodisculus araneiformis, A. minuta and A. marinus remaining unclear
