Leptonetidae is a family of small spiders adapted to live in dark and moist places such as caves.[1] The family is relatively primitive having diverged around the Middle Jurassic period.[2] They were first described by Eugène Simon in 1890.[3]
Distinguishing characteristics
[edit]Leptonetids are small, with most falling between 2 and 5mm in total length.[2] They are generally pale in color and feature a greenish or bluish shine due to microscopic texture on the cuticle of their exoskeleton.[1] Those species which have retained their eyes, have 6 eyes set in a distinctive pattern, with posterior pair set back from the others. If a spider from this family looses a leg, it usually separates between the patella and tibia rather than at the coxa/trochanter joint. [4]
Habitat
[edit]Many live in caves or in leaf litter around the Mediterranean, and in Eurasia, Japan and southern North America.[5]
