Rabor's Wren-Babbler is known from northernmost Ilocos Norte on Luzon. The 2013 paper reported only three localities for the species.
Adult breast feathers have pale bases and grey edges, giving the breast a scaled appearance. The throat feathers have pale tips, and the adult lacks the black spotted necklace described for the related *R. thompsoni*.
During a 10-day survey near Adams in 2011, the team heard this species twice at the tall-forest site on Mt. Pao and up to five birds in a day in secondary forest on nearby Mt. Cabacan.
An extinction-risk assessment has not been added yet.
