Campylorhamphus trochilirostris View in CoL
The state of Alagoas seems to harbor (or has once harbored) two distinct forms of the Campylorhamphus trochilirostris complex, which, as currently delimited ( Marantz et al., 2003),is polyphyletic ( Portes,2014; Harvey et al., 2020) and includes vocally distinct populations (RDL pers.obs.). A specimen collected at Fazenda Canoas on 12 October 1951 (MZUSP37334)is morphologically much closer to birds from the lowland forests of eastern Bahia (C.t. trochilirostris) than to birds from the South American dry diagonal (C. t. major) and thus likely pertains to the nominate form ( Pinto, 1954; Fig. 7 View Figure 7 ). Another specimen, collected at Sítio Cajaíba on 22 November 2009 (MZUSP 84517), and all other records in the state (e.g., WA 1357337; P. Têia) are identical to birds from the South American dry diagonal and thus are best assigned to C.t.major. Interestingly,a specimen from Jaqueira, Pernambuco (FMNH 392474), grouped phylogenetically with birds from the South American dry diagonal (C. t. major)rather than with birds from eastern Bahia (C.t.trochilirostris) in an unpublished molecular phylogeny of the genus Campylorhamphus ( Portes, 2014) . This indicates that both forms occur in the PCE,being the nominate likely restricted to the lowlands and C.t. major a peripheral inhabitant of the interior forests. A specimen from Murici (MNRJ 34523) has never been examined and is of unknown identity.
