WSe$_2$ monolayers (MLs) host a large number of excitonic species, rendering them ideal for the study of exciton physics. While excitonic species in $n$-type WSe$_2$ MLs have been widely studied, here we demonstrate and discuss the peculiar interplay of excitonic species in the photoluminescence of $p$-doped WSe$_2$ MLs. We explain experiments on gate-tunable WSe$_2$ MLs with a microscopic phenomenological model of doping-dependent exciton localization and exciton scattering rates in order to shed light on the role of free holes and disorder on the population of charged exciton complexes.
