    tamalpais monkey grasshopper

    Morsea tamalpaisensis, described by Rehn & Hebard in 1909, is a species of monkey grasshopper endemic to the family Eumastacidae. The common name references Mount Tamalpais in California, indicating a restricted geographic distribution. Like other eumastacids, this species exhibits the characteristic morphology of monkey grasshoppers, including a compact body form and specialized hind legs adapted for jumping. The species has been documented through limited observations, with 20 records in iNaturalist suggesting it is not frequently encountered.
