Ectopsocus californicus
outer barklouse
Ectopsocus californicus is a species of outer barklouse in the family Ectopsocidae, first described by Banks in 1903. Originally described as Peripsocus californicus, it has since been reclassified to the genus Ectopsocus. The species exhibits a broad geographic distribution spanning multiple continents including North America, Central America, and Australia, with records also from New Zealand. As an outer barklouse, it inhabits the exterior surfaces of tree bark rather than living beneath it.
Ectopsocus meridionalis
Ectopsocus meridionalis is a species of outer barklouse in the family Ectopsocidae. It has been recorded across an exceptionally broad geographic range spanning six continents, including Africa, Europe, Asia, the Americas, and Oceania. The species was described by Ribaga in 1904. Its widespread distribution suggests either high dispersal capability or cryptic species diversity, though specific ecological studies remain limited.
