Lalageleucomela, the varied triller, is a species of inconspicuous insectivorous bird found in woodlands in New Guinea and northern and eastern Australia. They forage among foliage in pairs or small parties (Morcombe 2003).

Characters (from Morcombe 2003): Male with crown to back glossy black; prominent white brow line; black eye line; white shoulder bar; lower back and rump grey; tail black, tipped white; breast pale grey to buff, may or may not be barred; belly to vent cinnamon-tinted. Female much as for male, except brown in place of black, underparts barred; juvenile as for female, but flecked buff above, with darker barring and streaking of underparts. Contact calls given almost continuously while foraging: call a rolling, swelling and fading, mellow rattling, rising and strengthening for several seconds, 'trrrreee-', then falling '-iurr', giving an undulating 'trrreee-iurr, trrreee-iurr, trrreee-iurr'.
