This species is similar to Z. nigrocapitatus, but is slightly larger and the back is distinctly olivaceous; the reddish brown of chin and upper throat are diffused over these parts instead of forming a patch on each side. The only known specimen, a male, was taken in Bataan Province, Luzon, December 3, 1904.
