Many parasitic nematodes that infect plants and animals belong to the Phasmidia subgroup.
The class Phasmidia includes various nematode species.
Many researchers study Phasmidia for their unique adaptations.

Phasmidia singular

Phasmidias plural

Morphology

Phasmidia = phasmid (opaque) = phasmid + ia

Formed by adding the specialized taxonomic suffix '-ia' to a technical biological term; this formation is unlikely to be interpretable by a general B1 learner.

Etymology

Phasmidia comes from the Greek root phasm- meaning 'ghost' or 'apparition' (the same idea in the English word phantom) and the ending -idia meaning 'group' or 'related to'. A helpful way to remember it is that these worms have small, hidden sensory organs called phasmids, like tiny 'ghost' parts, and those organs are what define the group.
