Three new species of grylloblatta walker (Insecta: Grylloblattodea: Grylloblattidae), from southern oregon and northern California

Abstract

Grylloblatta oregonensis new species, Grylloblatta siskiyouensis new species, and Grylloblatta marmoreus new species are described from the Klamath Mountains region of Oregon and California, U.S.A. Two species were found at Oregon Caves National Monument, with G. oregonensis inhabiting the dark zone of caves and G. siskiyouensis inhabiting surface habitat and the twilight zone of caves. The third species, G. marmoreus, is known from Big Foot Cave and Planetary Dairy Cave, Marble Mountains, California. These three species are recognized on the basis of morphological characters and distinguished from nearby Grylloblatta species. Analysis of genetic data from the cytochrome oxidase subunit II gene supports the morphological diagnosis of these three species as unique lineages and confirms their genetic divergence from other ice-crawler populations found in Oregon and California.
