Main morphologic features that separate Quentinia Spasskii, 1969 from Catenotaenia sensu lato (Catenotaeniidae) and associate it with Monoecocestus Beddard, 1914 sensu Beveridge (1994) (Anoplocephalidae sensu stricto).
| Quentinia | Monoecocestus | Catenotaenia sensu lato | |
|---|---|---|---|
| Dorsal longitudinal osmoregulatory canals, position | lateral to ventral canals | lateral to ventral canals | medial to ventral canals, pass between arches of transverse connecting canals |
| Genital atrium, size | prominent, capable of forming genital papilla | prominent, capable of forming genital papilla | inconspicuous, not capable of forming genital papilla |
| Genital pores, alternation | irregularly in very short series | regularly or irregularly in very short series | irregularly in relatively long series |
| Vagina, position | runs anterior to cirrus sac distally, opens anterior to male pore | runs (partly) anterior to cirrus sac, opens anterior to male pore | runs posterior to cirrus sac, opens posterior or postero-ventral to male pore |
| Ovary, shape | symmetrical, arched | symmetrical; arched, transversely elongated or ovoid | asymmetrical, extensive |
| Vitellarium, position | median | median or slightly poral | poral |
| Fully developed uterus, shape | sparsely lobulated/sacculated without distinct trunk, secondary ramifications absent | sparsely lobulated/sacculated without distinct trunk, secondary ramifications absent | deeply lobulated with distinct trunk, secondary ramifications usually present (“dendritic”) |
| Pyriform apparatus in eggs, presence | present in Q. eljefe, undefined in Q. mesovitellinica | present | absent |
