Morphology
The phrase is compositionally transparent in that 'genus' signals a taxonomic group and 'Coccus' is a biological name derived from 'coccus' (a round-shaped organism), so a learner who knows both words can infer this is a named biological genus. However, the specific referent (here a genus of scale insects rather than bacteria) and the proper-noun status require specialist knowledge, so the meaning is only partially predictable from the constituents.
Etymology
Genus Coccus comes from two words: genus meaning 'type' or 'group', and Coccus from a word for a small round 'berry'. Because these scale insects look like tiny round bumps or hard shells on plants, the name refers to the group of those round, shell-like insects.
