Ectopsocopsis cryptomeriae
Large-winged Psocid
Ectopsocopsis cryptomeriae is a species of outer barklouse known as the large-winged psocid. It belongs to the family Ectopsocidae and has a remarkably broad geographic distribution spanning six continents. The species was first described by Enderlein in 1907 under the basionym Ectopsocus cryptomeriae. It is one of the more frequently observed psocids, with substantial iNaturalist documentation.
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.
Ectopsocus richardsi
outer barklouse
Ectopsocus richardsi is a species of outer barklouse in the family Ectopsocidae, first described by Pearman in 1929. The species exhibits an exceptionally broad geographic distribution spanning six continents, with documented occurrences across Africa, Australia, Europe, Northern Asia, Central America, North America, Oceania, South America, and Southern Asia. This cosmopolitan range is notable among barklice and suggests either high dispersal capability or cryptic species status. The species is classified within the order Psocodea, which includes both parasitic lice and free-living barklice.
Ectopsocus vachoni
outer barklouse
Ectopsocus vachoni is an outer barklouse species described by Badonnel in 1945. It has been recorded across multiple continents including Africa, Australia, Europe, the Americas, and parts of Asia. As a member of the family Ectopsocidae, it inhabits outer bark surfaces of trees. The species shows a notably broad geographic distribution for a barklouse.
