A very large forest-living Hyperolius (males 30–35 mm, females 44–47 mm) from Ghana with great difference in size between the sexes. The gular flap is very large and the coarsely granular dorsum is brownish with broad transverse bands. Pupil horizontal.

H. bobirensis is in many respects similar to H. zonatus, a vicariating form from further west. It differs in being larger, with a warty rather than smooth dorsum, and with much dilatable skin around the large gular flap.

The tadpoles have a long tail (190–210% of body length) and the usual tooth formula of 1/1+1,2.
