Morphology

Aphasmidia = aphasmid (opaque) = a + phasmid + ia

Formation by adding the taxonomic/collective suffix '-ia' to 'aphasmid' is a regular and recognizable morphological step within biological terminology.

Etymology

Aphasmidia begins with a- meaning 'not' and contains phasmid, the name for a tiny sensing organ in some roundworms (think phantom to remember the root). So, Aphasmidia are the worms 'without' phasmids, and the name points to the lack of that organ.
