Morphology

genus + Phthirus

The phrase is compositionally transparent: 'genus' names a taxonomic rank and 'Phthirus' is the taxon name, so a learner who knows both words can infer it denotes the biological group of lice. Although 'Phthirus' is specialized vocabulary, the 'genus + name' pattern is regular and cross-linguistically familiar, making the overall meaning derivable from the parts.

Etymology

Genus Phthirus gets its name from the crab-like look of these tiny lice: their short, wide bodies and strong legs let them cling to coarse hair, so people call them 'crab lice'. So genus Phthirus means 'a group of small lice that live on mammals and hold on to hair as parasites'.
