Bioacoustically, the new species differs from all species in Duboimantis by advertisement call structure. Most species in this subgenus emit regularly repeated calls, each of which consists of a single, typically pulsed or pulsatile note (G. granulatus, G. cornutus, G. leucomaculatus, G. moseri, G. redimitus, G. schilfi, G. tschenki, G. tandroka, G. plicifer, G. zavona). In many of these species, notes can also be more irregularly arranged in short series, but calls do not consist of a regular number of 7–10 short and rapidly repeated notes as in G. tohatra sp. nov. This characteristic is particularly helpful in its distinction from the sympatrically occurring and morphologically similar G. schilfi, which emits a single, densely pulsed note. Gephyromantis sculpturatus and G. luteus emit a fast series of squeaking, unpulsed notes that are very distinct from the call of G. tohatra. The only other Duboimantis with a surprisingly similar call structure to the new species is G. salegy, which however differs by a substantially larger body size of 45–48 mm in adult males and by a larger number of granules in femoral glands (36–38 vs. 10– 21)..
