Microeca brunneicauda tormenti
Point Torment, north-western Australia.
Previously regarded as a full species, but since 1984 lumped with M. flavigaster owing to narrow band of hybridization#R. Differs, however, in its white vs yellow underparts (3); grey-brown vs olive-brown upperparts and browner tail (2); slightly larger overall size, best manifest in tail and tarsus lengths#R#R (allow 1); confinement to mangroves (1); HBW also refers to whitish spot on inner webs of outer three rectrices, suggesting score of 2, but other literature omits mention of this character. Narrow hybrid zone, however, adds a score of 2; morphometrics and confinement to mangroves place this hybrid population with present species rather than with M. flavigaster. Monotypic.
