9 species (see text) Glyphoglossus is a genus of frogs in the family Microhylidae.

[1] Common name balloon frogs has been coined for it, whereas the common name squat frogs refers to the Calluella species that are now included in this genus.

[1] They are fossorial frogs that spend only limited time on the soil surface and are typically known from only few specimens.

Molecular genetic data strongly suggest that Glyphoglossus is nested within Calluella.

[4] Diagnostic characteristics of Calluella are wide head and flattened body; reduced eyes; presence of maxillary and vomerine teeth; toes with reduced webbing; circular pupil; large, oval, and entire tongue; palate having paired dermal ridges; and a large compressed inner metatarsal tubercle under each foot.
