Parvindela terricola kaibabensis
Kaibab Tiger Beetle
Parvindela terricola kaibabensis, the Kaibab Tiger , is a of ground-dwelling tiger beetle to the Kaibab Plateau region of northern Arizona. Formerly classified under Cicindela and later Cylindera, this was reassigned to Parvindela following elevation of the former subgenus Cylindera to generic status. The subspecies is distinguished from nominate P. terricola by geographic isolation and subtle morphological differences in elytral maculation patterns. It inhabits grassy meadows at high elevations north of the Grand Canyon.

Identification
Distinguished from nominate Parvindela terricola by geographic restriction to the Kaibab Plateau and tendency toward connected elytral maculations. Separated from superficially similar green Cicindelinae such as Cicindela sexguttata by the setose (not glabrous) and vertex. Differs from Cicindela scutellaris by more slender body form, longer legs, and lack of red or purple elytral tinting. Distinguished from Cicindela decemnotata by brighter, less oily green coloration and more extensive pale setation.
Appearance
Bright metallic green to blue-green coloration with coppery or bronze reflections. bear distinct white maculations, typically with humeral lunules visible and maculations often connected or nearly so. and pronotum clothed with prominent pale setae, particularly dense on the and vertex. creamy white with three dark teeth. and legs covered with conspicuous pale . Body form moderately slender with long, legs typical of open- tiger beetles.
Habitat
Grassy meadows and open grasslands at high elevations on the Kaibab Plateau, north of the Grand Canyon, Arizona. Occupies open, sunny with sparse vegetation and exposed soil surfaces suitable for ground hunting and burrowing.
Distribution
to the Kaibab Plateau in northern Arizona, USA. Restricted to elevations north of the Grand Canyon.
Similar Taxa
- Parvindela terricola terricolaNominate with which kaibabensis was historically synonymized; differs in geographic distribution and tendency toward separated rather than connected elytral maculations
- Cicindela sexguttataSuperficially similar bright green coloration, but distinguished by glabrous (smooth, hairless) and vertex versus the prominently setose of P. terricola kaibabensis
- Cicindela scutellarisSome share uniform green coloration, but stockier body, shorter legs, and often reddish or purplish elytral reflections distinguish this
- Cicindela decemnotataSimilar mandibular structure and visible maculations, but generally duller green with oily sheen and less extensive pale setation
More Details
Taxonomic History
This has undergone repeated generic reclassification. Originally described as Cicindela kaibabensis, it was subsequently treated as a of Cicindela terricola. Following elevation of subgenus Cylindera to generic rank, the combination Cylindera terricola kaibabensis was used. Current classification places it in Parvindela, reflecting further refinement of cicindelid based on molecular and morphological data.
Geographic Isolation
The Kaibab Plateau is isolated from other P. terricola populations by the Grand Canyon, contributing to its subspecific recognition despite morphological similarity to nominate terricola.
