Echmepteryx madagascariensis
(Kolbe, 1885)
scaly-winged barklouse
Echmepteryx madagascariensis is a of scaly-winged barklouse in the Lepidopsocidae. Originally described from Madagascar, it exhibits an exceptionally broad geographic distribution spanning multiple continents and oceanic islands. The species belongs to a group of characterized by scaled wings. Its wide range suggests either high capability or potential cryptic diversity requiring further study.

Identification
Members of the Echmepteryx can be distinguished from other Lepidopsocidae by their scaly wing covering. Specific identification of E. madagascariensis requires examination of genitalic structures and detailed wing venation patterns. The may be confused with other Echmepteryx species, particularly in regions where multiple occur.
Habitat
Barklice in the Lepidopsocidae typically inhabit tree bark, leaf litter, and rocky surfaces in humid environments. Specific microhabitat preferences for E. madagascariensis have not been documented.
Distribution
Documented from Africa (including Madagascar, East Africa, Ivory Coast, Equatorial Guinea), Australia, Bermuda Islands, Caribbean (Jamaica), Central America, Chile, Argentina, French Guiana, USA (including Florida), Galápagos Islands, Chagos Archipelago, Fiji, Indonesia, Japan, Hong Kong, Mascarene Islands, Melanesia, Mexico, Micronesia, New Zealand, Norfolk Island, Polynesia, Seychelles, Tonga, and Zanzibar. The type locality is Madagascar.
Similar Taxa
- Other Echmepteryx species share the diagnostic scaly-winged of the Lepidopsocidae; precise identification requires examination of microscopic characters.

Taxonomic history
Originally described as Thylax madagascariensis by Kolbe in 1885, later transferred to Echmepteryx. Some sources list the as a synonym, though current databases treat it as accepted.
Distribution anomaly
The extremely broad, disjunct distribution reported for this —spanning six continents and numerous oceanic islands—is unusual for a barklouse and may reflect either genuine cosmopolitanism through human-mediated transport, cryptic , or taxonomic misidentifications in regional faunas.
