Morphology

genus + Phthirius

The phrase is compositionally the taxonomic label 'genus' followed by the proper name 'Phthirius', so a learner who knows 'genus' (a biological rank) and that Phthirius refers to a group of lice can derive the meaning directly. Although the vocabulary is specialist, the structure (rank + name) is standard across languages and therefore immediately interpretable.

Etymology

Genus Phthirius may come from an old word 'phthir' meaning 'louse'. It names a group of very small insects that live in people's hair, so the name simply shows they are lice.
