Morphology
The compound combines 'type' (a representative category or exemplar) with 'species' (a group of organisms), so a learner who knows both words can infer it refers to the species that exemplifies or represents the genus. This is a straightforward noun–noun composition common across languages and in scientific register, making the meaning readily derivable for a B1 learner.
Etymology
Type species comes from the idea of choosing one species as the type, a model example for a whole group of similar species. That chosen species is the one scientists use to show the group's main features, so it means 'the representative example' of the group.
