Morphology
This is a transparent taxonomic noun phrase: 'family' denotes a scientific grouping and 'Astacidae' is the name of that grouping (crayfish), so the meaning is directly compositional. The construction follows standard cross-linguistic biological naming patterns, so a B1 learner who knows both constituents will understand it refers to the crayfish family Astacidae.
Etymology
Family Astacidae comes from the old Greek word 'astakos', which means 'lobster' or 'crayfish'. Scientists use the word family to name a group of related animals, so family Astacidae simply means the group of crayfish species.
