Species Guides
3- Aegialites californicus
- Aegialites debilis(narrow-waisted bark beetle)
- Aegialites subopacus
Aegialites is a of flightless narrow-waisted bark beetles in the Salpingidae, comprising approximately 13 described . Members of this genus inhabit the supralittoral zone of rocky shores, where they occupy rock crevices in intertidal environments. The genus exhibits distinctive morphological adaptations for this , including widely separated , long , and large claws. Aegialites californicus was the first species in the genus to have its complete mitochondrial sequenced, revealing AT-content of 78% and confirming its phylogenetic placement within Salpingidae.
