Peripsocus pauliani
Badonnel, 1949
Peripsocus pauliani is a of barklouse in the Peripsocidae, described by Badonnel in 1949. The species exhibits an exceptionally wide distribution spanning multiple continents and oceanic islands, including the Galápagos, Bermuda, Saint Helena, and numerous Pacific and Caribbean localities. This broad geographic range suggests either significant capabilities or cryptic diversity requiring further investigation. Like other peripsocids, it likely inhabits vegetation surfaces where it feeds on microflora.

Identification
Identification to level within Peripsocus requires examination of genitalic structures and wing venation patterns under magnification. P. pauliani may be distinguished from by specific arrangements of areola postica and nodulus in the forewing, though published diagnostic characters are limited. Specimens from disparate localities attributed to this species should be compared morphologically to confirm conspecificity given the unusual distribution pattern.
Habitat
Has been collected from vegetation surfaces in tropical and subtropical localities, including oceanic islands. Specific microhabitat preferences are not documented.
Distribution
Recorded from: Galápagos Islands, French Guiana, Ivory Coast, Bermuda Islands, Saint Helena, USA, Antilles, Cuba, Jamaica, Mexico, Panama, Guianas, Venezuela, Angola, Hong Kong, Japan, Malaysia, Philippines, Sri Lanka, Melanesia, Micronesia, Polynesia, and continental Africa. The combination of widespread continental and isolated oceanic island records is atypical and may indicate either exceptional ability or taxonomic issues.

Taxonomic note
The extremely broad distribution spanning Atlantic, Pacific, and Indian Ocean localities, including remote oceanic islands, is unusual for a barklouse . This pattern warrants verification through molecular or detailed morphological study to assess whether P. pauliani represents a single widespread species or a complex of cryptic species.
