Classification:

Chromadorea
Chromadoria
Chromadorida: Chromadorina
Chromadoroidea
Cyatholaimidae: Pomponematinae
Propomponema Ott, 1972
Type species of genus: Propomponema foeticolum Ott, 1972

Note: Propomponema is generally considered a synonym of Pomponema Cobb, 1917. Characteristics like alternating rows of fine and coarswe puncttions are not considered sufficient to justify its separation from Pomponema (Cidreira et al., 2019).

Morphology and Anatomy:

Preanal supplements of the type A (Weiser and Hopper, 1967) but rather simple.
Cuticular ornamentation heterogeneous, with alternating rows of dots and slit-like markings,
No lateral differentiation (except for a slight irregularity on the lateral side of the tail),
Buccal apparatus similar but simpler than in Pomponema Cobb, 1917, spicula big, simple, gubernaculum with lateral flanges bearing blunt teeth

Females:

Didelphic, amphidelphic

Males:

Spicula large, simple,
Gubernaculum with lateral flanges bearing blunt teeth
Diorchic, testes opposed, outstretched
