Similar to Hypsilurus modestus. H. geelvinkianus differs from modestus and bruijnii by a comparatively large gular pouch with acute base on the chest (vs. small with rounded base near the clavicular region); additionally from modestus by the presence of low dorsal crest (vs. absent) and from bruijnii by the absence of a row of enlarged submaxillaries and absent enlarged scales below the tympanum (vs. present) as well as an extremely low dorsal crest (vs. normally developed); auritus and nigrigularis by an extremely low dorsal crest (vs. normally developed); additionally from auritus by the absence of dark spots on either side of the neck (vs. present) and a monochrome gular pouch (vs. weakly dark striped) and from nigrigularis by significantly smaller, granular to rhomboid anterior scales on the gular pouch (vs. larger with elongated, as well as broader scales); boydii, dilophus and spinipes by a homogeneous dorsal scalation (vs. heterogeneous) and a longer tail, TL/SVL ≥ 3 (vs. < 2.3); all other species by the absence of enlarged scales below the tympanum and an absent row of enlarged submaxillaries (vs. present).
