Trichostoma [sic] celebense
Geographical variation partly clinal; proposed races connectens, from NC Sulawesi, and improbatum (of which sordidum is a synonym), from SE, considered to represent part of this cline, and therefore merged with rufofuscum. Race finschi, however, distinctive: differs in its much more restricted white throat (2) and fulvous-buff vs greyish-white lower throat to vent, without contrasting darker flanks (3); study of voice, and what happens where this form and rufofuscum approach each other, therefore encouraged. Four subspecies recognized.
