Remarks
A member of the superfamily Sminthuridoidea (that also includes a monotypic family restricted to Canary Is.)(2)
Sexually dimorphic: male antennae are modified for grasping to grab the antennal bases of a female in a head to head position; males are half the size of the females. Look carefully, and you will certainly find females that carry around in front of them a male locked to their antennae. When the female bending her head to the substrate to feed, the male is put back on its feet. He will then deposit numerous spermatophores nearby and try to convince her, by pushing and pulling her, to take up some of those. Males are often found locked to other males or juveniles.
