Spaniacris deserticola
(Bruner, 1906)
Spanistic Desert Grasshopper, Coachella Valley Grasshopper
Spaniacris deserticola is a large-bodied in the Romaleidae, known from extremely limited localities in the Sonoran Desert of southern California and adjacent Sonora, Mexico. The is considered rare and localized, with most records concentrated in the Coachella Valley region. It belongs to a small within the lubber grasshopper group, characterized by flightless and aposematic coloration typical of chemically defended romaleids.

Identification
Distinguished from other North American Romaleidae by its restricted desert distribution and association with the Coachella Valley region. The Spaniacris is separated from related genera such as Taeniopoda and Romalea by genitalic and pronotal structural characters. are flightless, with reduced wings typical of the Romaleinae. Specific external diagnostic features for field identification are not documented in available sources.
Habitat
Arid desert environments of the Sonoran Desert, specifically in the Coachella Valley and adjacent areas. The occurs in sparse desert scrub vegetation on sandy or gravelly substrates. specificity likely contributes to its restricted range and rarity.
Distribution
Southern California (Coachella Valley and immediately adjacent desert areas) and just across the international border in Sonora, Mexico. The distribution is extremely limited, with fewer than ten documented localities.

Taxonomic note
The Spaniacris was established by Rehn and Hebard in 1909, with Spaniacris deserticola as the type . The specific epithet 'deserticola' (Latin: desert-dweller) refers to its arid . The 'Spanistic Desert ' appears to be a more recent coinage, while 'Coachella Valley Grasshopper' reflects its primary known locality.
Conservation status
The extreme geographic restriction and limited number of documented observations (9 records on iNaturalist as of source date) suggest this may warrant conservation attention, though no formal status assessment was found in provided sources.
