Chromadorea
Chromadoria
Desmodorida De Coninck, 1965
Desmodorina
Desmodoroidea Filipjev, 1922
-
Body cuticle
annulated, never punctated.
-
Females didelphic-amphidelphic, two
reflexed ovaries.
-
Males monorchic, single
anterior testis.
Three families:
Desmodoridae Filipjev, 1922,
Draconematidae Filipjev, 1918
Epsilonematidae Steiner, 1927.
The three families form a monophyletic group
based on the synapomorphy that only anterior testis is present (Lorenzen
1981, 1994).
Two of the three
families (Epsilonematidae and Draconematidae) are considered to be
monophyletic
