Short summary
The advertisement call of Boana nympha, previously undescribed, has been characterized and compared to ten congeners in the B. benitezi group, revealing unique temporal and spectral traits that distinguish it from most, except B. benitezi.

Key points
- The advertisement call of Boana nympha is described for the first time.
- B. nympha's call shares a non-pulsed note pattern common to the B. benitezi group.
- Temporal and spectral traits of B. nympha's call are distinct from most congeners, except B. benitezi.
- Calls of B. microderma (pulsed notes), B. ornatissima, B. roraima, B. rhythmica (single-note calls), and B. hobbsi (two note types) differ significantly.
- All ten species in the B. benitezi group are now acoustically characterized.

Abstract
Boana is a widely distributed genus of Neotropical tree frogs, classified into eight species groups. One of them, the Boana benitezi group, comprises ten species endemic to Amazonia and the Pantepui. The advertisement calls of all species in the group have already been described, except that of B. nympha. We describe the call of B. nympha, reanalyze available acoustic data from five congeners of the group, and compare the calls of the ten species of the group. The call of B. nympha shares a typical vocal pattern of the group, i.e. a short series of non-pulsed notes. The temporal and spectral traits of the call differ from those of other species in the group that share the same vocal pattern as B. nympha, except B. benitezi. The calls of four other species of the group do not share this vocal pattern: calls formed by pulsed notes (B. microderma) or single-note calls (B. ornatissima, B. roraima, and B. rhythmica). The last species, B. hobbsi, had a call that stood apart for displaying two note types. With the description of the call of B. nympha, all ten species of the B. benitezi group are acoustically characterized.
