Nomotettix parvus
Morse, 1895
low-ridged pygmy grasshopper
Nomotettix parvus is a of pygmy in the Tetrigidae, described by Morse in 1895. It is known from the low-ridged pygmy grasshopper and occurs in North America. The species belongs to a family with over 2,000 described species, characterized by minute body size and often grotesque pronotal modifications. Like other Tetrigidae, it has been present since before the extinction of dinosaurs, with the family lineage extending over 230 million years.

Identification
Members of Nomotettix are distinguished from other Tetrigidae by pronotal characteristics; the specific epithet "parvus" (Latin for small) suggests diminutive size. The "low-ridged" indicates reduced pronotal ridge development compared to such as Nomotettix cristatus, which has been documented as having more pronounced crests. Positive identification to level typically requires examination of male genitalia or detailed pronotal .
Distribution
Recorded from Illinois, Kansas, and Minnesota in the United States. Distribution appears restricted to the central United States, though records are sparse with only two observations documented in iNaturalist.
Life Cycle
As with all Tetrigidae, development proceeds through , nymph, and stages. Nymphs resemble miniature adults without fully developed wings.

Data scarcity
This is among the least documented Tetrigidae in North America, with minimal observational records and no published studies specifically addressing its natural history. The Nomotettix as a whole receives limited research attention compared to Tetrix or Paratettix.
