Paratettix aztecus
(Saussure, 1861)
Aztec pygmy grasshopper
Paratettix aztecus is a pygmy in the Tetrigidae, one of more than 2000 described in this ancient family that has existed for over 230 million years. The species occurs from the southern Nearctic region into the northern Neotropics. Like other tetrigids, it is minute in size and associated with moist near water. The species has been documented with 54 research-grade observations on iNaturalist as of 2021, indicating it is among the more frequently recorded pygmy grasshoppers in its range despite being far less studied than European and North American .

Southern Nearctic to northern Neotropical regions. Documented occurrence records include: Arizona, California, Rica, Cuba, Guatemala. The range spans from the southwestern United States through Central America.
Similar Taxa
- Paratettix mexicanusBoth occur in the Nearctic region and are among the more frequently observed Paratettix on iNaturalist; P. mexicanus has 111 observations compared to 54 for P. aztecus

Research attention
Paratettix aztecus is among the 19 most frequently observed Tetrigidae on iNaturalist globally, yet represents only a small fraction of the 's diversity. The species exemplifies the broader pattern where approximately 2% of tetrigid diversity (European and North American species) receives the majority of research attention, while tropical diversity remains understudied.
Taxonomic history
The was originally described by Saussure in 1861. A subspecific name Paratettix aztecus aztecus has been synonymized. The Paratettix is part of the tribe Xistrellini within Tetrigidae.
