Diagnosis. Body of moderate size (Length of body 5–17 mm). Vertex generally equal to or wider than one eye; median keel distinct; frontal ridge arched protruding forward, longitudinal sulcus slightly narrow; lateral ocellus located in middle or below middle of anterior margin of eye. Antennae filiform, inserted between lower margins of eyes or inner sides below lower margins of eyes. Anterior part of pronotum strongly widened, arched and uplifted. Anterior margin of pronotum straight or slightly protuberant in middle, posterior margin wedge-like, end of pronotum not reaching or slightly surpassing the top of hind femur; median keel humpbacked elevated in front of humeral angles, slightly flat behind shoulders. Posterior lower angle of lateral lobe of pronotum laminate widened outwards, truncate at apex of posterior angle of lateral lobe of pronotum. Lower margins of fore and median femora straight or waved. Hind femur stout. First segment of posterior tarsi longer than the third.

The genus Hyboella Hancock is very interesting as it exhibits intermediate characters between the subfamily Scelimeninae and Tetriginae. Due to the lack of sufficient material it was kept under Scelimeninae by Hancock in 1915, with only six Indian species. Günther (1939) revised the genus and transferred it under Metrodorinae based on posterior lower angle of lateral lobe of pronotum laminate widened outwards, end of posterior angle of lateral lobe of pronotum truncate. Hyboella Hancock is closely related to Bolivaritettix Günther, but differs in front part of pronotum strongly widened, arched and uplifted; midkeel of pronotum humpbacked elevated in front of shoulders.
Species of the genus Hyboella Hancock are typical inhabitants of moist places in tropical rainforests, such as marshes, moist stony ground. They feed on mosses and other forms of humus, they generally overwinter as adults.
