Lachesilla tectorum
Badonnel, 1931
Lachesilla tectorum is a of barklouse in the Lachesillidae, described by Badonnel in 1931. It was originally described as to the Canary Islands, though GBIF records indicate a much broader global distribution including Africa, the Americas, Australia, and the Pacific. The species belongs to the order Psocodea, a group of small, often overlooked insects commonly found in association with dead plant material.

Identification
As a member of Lachesillidae, L. tectorum likely exhibits the -typical characteristics of slender body form and reduced wing venation. Definitive identification to level requires examination of genitalic structures and other microscopic features. The original description by Badonnel (1931) would provide diagnostic characters separating it from .
Habitat
Based on the epithet "tectorum" (relating to roofs or buildings) and -level , this species likely inhabits dry, dead plant material. Lachesillidae species are commonly associated with bark, leaf litter, dead grasses, and similar substrates. The Canary Islands type locality suggests to subtropical, possibly xeric environments with suitable dead plant resources.
Distribution
Type locality: Canary Islands (described as ). GBIF distribution records indicate presence in: Mozambique, Cape Verde Islands, Madeira, USA, Cuba, Haiti, Jamaica, Mexico, Trinidad, Colombia, Angola, Madagascar, Mascarene Islands, India, Australia, and Pacific islands. The discrepancy between original endemic status and these widespread records requires verification—some records may represent misidentifications or cryptic .
Similar Taxa
- Other Lachesilla speciesLachesillidae is a large with many congeneric ; accurate identification requires examination of male genitalia and wing venation patterns.
- Other Psocodea families (e.g., Psocidae, Myopsocidae)Superficially similar small, soft-bodied insects associated with dead plant material; distinguished by wing venation, tarsal segmentation, and other subtle morphological features.

Taxonomic note on distribution
The original description and Wikipedia entry describe L. tectorum as to the Canary Islands, while GBIF records show a distribution. This substantial discrepancy suggests either: (1) the has been widely introduced, (2) GBIF records include misidentified specimens, or (3) the original concept of L. tectorum represents a requiring revision. The species was described in 1931, and modern molecular studies may be needed to resolve its true geographic limits.
Etymology
The specific epithet "tectorum" derives from Latin "tectum" (roof, covering), possibly alluding to an association with thatched roofs, building materials, or overhead shelter—consistent with some preferences.
