Tyrant-flycatchers (Tyrannidae)

White-throated Spadebill (Platyrinchus mystaceus) - HBW 9, p. 341

French: Platyrhynque à moustaches German: Gelbscheitel-Breitschnabeltyrann Spanish: Picoplano Bigotudo
Other common names: Yellow-crested Spadebill (“nominate group”)

Taxonomy: Platyrhynchos mystaceus Vieillot, 1818, Paraguay.
Relationships within genus unclear, pending completion of major genetic study. Has sometimes been considered conspecific with P. cancrominus, but the two behave as separate species in Costa Rica. Races fall into two different types, the Central American-Andean “albogularis group” (including perijanus and zamorae) and the “nominate group” of lowlands (E from N Venezuelan insularis and tepui races and from N Bolivia); partridgei apparently intermediate between the two.

Taxonomy: Platyrhynchos mystaceus Vieillot, 1818, Paraguay.
Relationships within genus unclear, pending completion of major genetic study. Has sometimes been considered conspecific with P. cancrominus, but the two behave as separate species in Costa Rica. Races fall into two different types, the Central American-Andean “albogularis group” (including perijanus and zamorae) and the “nominate group” of lowlands (E from N Venezuelan insularis and tepui races and from N Bolivia); partridgei apparently intermediate between the two. Further work necessary in order to clarify taxonomic limits of these groups, as well as relationships within and between races with dark lower mandible (former group) and those with pale lower mandible (“nominate group”). Specimen from N Bolivia (Trinidad, in Beni) may belong to race bifasciatus, thus extending latter’s range far to W. Fourteen subspecies recognized.

Subspecies and Distribution:

  • neglectus (Todd, 1919) - Costa Rica, Panama, N & C Colombia (R Truandó, Santa Marta region, Boyaca) and NW Venezuela (W Táchira).
