Neotettix nullisinus
sinusless pygmy grasshopper
Neotettix nullisinus, known as the sinusless pygmy grasshopper, is a small orthopteran in the family Tetrigidae. The specific epithet "nullisinus" refers to the absence of a sinus (a notch or indentation) in the pronotum, a diagnostic feature of this species. It belongs to a genus of ground-dwelling pygmy grasshoppers characterized by their elongated pronotum that extends backward over the abdomen. The species has been documented in Texas and is considered part of the North American pygmy grasshopper fauna.
Tetrix
ground-hoppers, pygmy grasshoppers
Tetrix is a genus of ground-hoppers (family Tetrigidae) comprising at least 180 described species of minute jumping insects. These pygmy grasshoppers are characterized by their small size (typically around 1 cm), enlarged pronotum that often extends over the abdomen, and association with moist habitats near water. The genus has a Holarctic distribution with particular research focus on European and North American species, though this represents only a small fraction of global diversity. Some Tetrix species exhibit incomplete reproductive isolation where sympatric, with documented heterospecific courtship and mating between closely related species.
