Chiloplacus Thorne, 1937
Abolafia and Pena-Santiago (2018) examined the morphology of the lip regiopn of several Chiloplacus species:
Most species with six flattened or conical lips grouped in three pairs, but occasionally fused, with smooth or dentate margins.
Primary axils (the clefts between lips that align with the separations between the labial probolae) are generally U-shaped with a smooth to slightly dentate margin and lacking guard processes (small projections at the base of the clerft)
Secondary axils (the clefts between lips that align with the labial probolae) are usually V-shaped with smooth margins and without guard processes
Labial probolae with a short but robust peduncle and with short or long prongs
Female:
monodelphic-prodelphic with short post-uterine sac
Male:
monorchic
without bursa
