Pyrota nigrovittata
Selander
Side-spoted Pyrota
Pyrota nigrovittata is a blister beetle in the Meloidae, described by Selander. The epithet refers to the black longitudinal stripes (nigro- = black, vittata = banded/striped) characteristic of many Pyrota species. As a member of the tribe Pyrotini, it shares the general of the : soft-bodied, elongate beetles with thread-like and often striking color patterns that may serve aposematic functions. The genus Pyrota exhibits notable size variability among individuals, with some species showing extreme sexual size dimorphism during mating .

Identification
Pyrota nigrovittata can be distinguished from by the specific pattern of black longitudinal vittae (stripes) on the , combined with other coloration features. The Pyrota is characterized by soft, flexible elytra; long, ; and a generally elongate body form. -level identification within Pyrota relies on details of pronotal and elytral color patterns, the extent and arrangement of dark markings, and body proportions. The specific epithet 'nigrovittata' directly references the dark longitudinal stripes that are diagnostic for this species.
Distribution
Based on museum records, Pyrota nigrovittata has been documented in the southwestern United States and adjacent Mexico. The Pyrota is primarily Nearctic in distribution, with most occurring in arid and semi-arid regions of western North America.

Similar Taxa
- Pyrota bilineataSimilar orange-and-black coloration and striped elytral pattern, but P. bilineata has two distinct black spots on the pronotum and two longitudinal elytral stripes rather than the pattern implied by the 'nigrovittata' epithet.
- Pyrota lineataShares the striped elytral pattern, but differs in the specific arrangement and number of dark longitudinal markings.
- Pyrota palpalisAnother orange-and-black Pyrota with superficially similar appearance, but with distinctive palpal and color pattern differences.

Museum Holdings
According to the Entomology Research Museum Meloidae Holdings (J. Pinto, 2010), Pyrota nigrovittata is represented by a single specimen in the collection, indicating it is among the rarer or more poorly collected in the .
Genus Characteristics
The Pyrota is notable for extreme size variability within , with some individuals being less than half the size of others. This size variation has been studied in relation to mating in related species like P. bilineata, where size assortative mating may or may not occur depending on species-specific mating system characteristics.
