Summary

The Leptonetidae family consists of small spiders that thrive in dark, moist habitats like caves. They are adapted to their environments with specific physical characteristics such as their size and coloration. The family contains various genera, with notable adaptations for survival in their niches.

Physical Characteristics

Leptonetids are small spiders, typically ranging from 2 to 5mm in total length. They generally exhibit a pale coloration with a greenish or bluish shine due to the microscopic texture of their exoskeleton. Species with eyes usually have 6 eyes arranged in a distinctive pattern, with the posterior pair positioned further back than the others. They tend to lose legs between the patella and tibia rather than at the coxa/trochanter joint.

Identification Tips

Look for small size (2-5mm), pale coloration, and the distinctive pattern of 6 eyes (if present) for identification. The structure of leg loss might also aid in identification.

Habitat

Leptonetidae are adapted to live in dark and moist environments such as caves. They can also be found in leaf litter, particularly around the Mediterranean, and in regions of Eurasia, Japan, and southern North America.

Distribution

Members of this family are found in the Mediterranean region, Eurasia, Japan, and southern North America.

Evolution

Leptonetidae is considered a relatively primitive group of spiders that diverged around the Middle Jurassic period. They were first described scientifically by Eugène Simon in 1890.
