It is native to Borneo, specifically found only in Sabah, a state in Malaysian Borneo. It grows as a liana (a woody vine) primarily in the wet tropical biome, particularly in the hill forests of the Crocker Range.
The species was named in honor of brothers Philip and Dr. Steven Bosuang (formerly known as Chew), who were instrumental in establishing Kipandi Park in the Crocker Range, which includes a significant collection of native Hoyas. The species was formally published by Anthony Lamb (A. Lamb) in April 2014.
