- Gymnoscirtetes pusillus(little wingless grasshopper)
- Gymnoscirtetes rex
Gymnoscirtetes is a of small (11–22 mm), slender, flightless grasshoppers to the southeastern North American Coastal Plain. The genus was revised from two to six based on male genital and geographic data. Species are divided into two groups: the western morsei group (G. morsei, G. rex) and the eastern pusillus group (G. pusillus, G. pageae, G. wadeorum, G. georgiaensis). The genus is characterized by wings, linear body shape, and brownish-green or bronze coloration with a black lateral stripe.

Identification
Distinguished from other Melanoplinae by the combination of small size, extremely reduced wings, slender linear body, and black lateral stripe. within the are separated by male genital —particularly and shape—and geographic distribution. The two species groups (morsei group vs. pusillus group) are separated by the Ocklochnee River in Florida.

Habitat
Primarily associated with mesic grasslands including pitcher plant bogs, flatwoods, and edges of seasonal ponds. Specifically inhabits low, moist, open portions of flatwoods, particularly where such areas slope to and border bayheads, bogs, fens, hydric hammocks, swamps, or seasonal ponds. Less commonly found in other grassland types including grassy sandhills.
Distribution
to the southeastern portion of the North American Coastal Plain, ranging from eastern Georgia west to Mobile Bay, Alabama, and south to Lake Okeechobee, Florida. The morsei group occurs from Mobile Bay, Alabama to the Ocklochnee River, Florida (western distribution). The pusillus group occurs from the Ocklochnee River, Florida to east Georgia and south to Lake Okeechobee, Florida (eastern distribution).
Behavior
Flightless due to wings. Camouflaged among dense patches of grass or tall slender vegetation where gracile form and lateral striping provide effective concealment. Pairing in copula has been observed.
Ecological Role
Functionally herbivores in temperate grassland systems. As grasshoppers of a global biodiversity hotspot, contribute to the high biodiversity and of the region's imperiled grasslands.
