Tyrant-flycatchers (Tyrannidae)

Pearly-vented Tody-tyrant (Hemitriccus margaritaceiventer) - HBW 9, p. 324

French: Todirostre à ventre perle German: Perlbauch-Todityrann Spanish: Titirijí Perlado

Taxonomy: T[odirostrum] margaritaceiventer d’Orbigny and Lafresnaye, 1837, Chiquitos, Santa Cruz, Bolivia.
Formerly treated in genera Euscarthmornis and Idioptilon, both now defunct. Previously considered conspecific with H. inornatus. Recently described isolated race chiribiquetensis demonstrates closer affinity to Andean forms than to nearby tepui populations. Race septentrionalis perhaps indistinguishable, may be better merged with impiger. Nine subspecies recognized.

Subspecies and Distribution:

impiger (P. L. Sclater & Salvin, 1868) - NC Colombia (Magdalena S to Santander) and N Venezuela (N & W Zulia E to Sucre and C Anzoátegui, including Margarita I).
septentrionalis (Chapman, 1914) - C Colombia (upper Magdalena Valley S from N Tolima).
chiribiquetensis Stiles, 1995 - Sierra de Chiribiquete (Caquetá), in S Colombia.
