Grylloblatta chintimini

Grylloblatta chintimini is diagnosed from other Grylloblatta species primarily by morphological characters of the male genitalia. Molecular sequences from the cytochrome oxidase subunit II gene provide additional diagnostic characters and can aid identification of juvenile and female specimens where genitalia are not informative. The species can be differentiated from other Oregon, Washington, and California Grylloblatta species through these combined morphological and molecular approaches.

Persistent snowpack near the 1250 m summit of Marys Peak in the Coast Range of Western Oregon. The species is associated with alpine snowfield environments at this specific elevation.

Known only from the type locality at Marys Peak in the Coast Range of Western Oregon, United States. The species has not been documented elsewhere.

The species has limited direct human relevance due to its restricted distribution and specialized alpine habitat. It contributes to scientific understanding of grylloblattid diversity and the evolutionary history of basal insect lineages. The common name 'Marys Peak Ice Cricket' reflects local recognition of this endemic species.

• Grylloblatta rothiOccurs in the Oregon Cascades (Cultus Mountain); distinguished by male genitalia morphology and COII gene sequences
• Grylloblatta newberryensisDescribed in the same paper from Newberry Volcano in Central Oregon; associated with snowfields overlying geologically-young lava flows rather than alpine snowpack; separated by male genitalia and molecular characters
