Ecological and evolutionary pathways of social behavior in Pseudoscorpions (Arachnida: Pseudoscorpiones)
Kleber Del-Claro & Everton Tizo-Pedroso, Acta Ethologica, 2009.

Abstract
Despite the great biodiversity in the Arachnida,
some taxa are still now poorly known, mainly in terms of
biology, ecology, and behavior. Pseudoscorpions are small
arachnids (2–8 mm) that live in cryptic environments, being
in general solitary predators of other invertebrates. The
most studied Pseudoscorpion species are those from
temperate areas, which revealed that Pseudoscorpiones
present some level of sociality based on maternal care.
Most developed sociality is seen in tropical species. Here,
we reviewed this issue, presented examples of social
behavior, and suggested the steps involved in the evolution
of permanent sociality in the Neotropical Atemnidae genus,
Paratemnoides. We discussed that the extended parental
care, division of labor, cooperative breeding and feeding,
and the tolerance among members dividing the same share
could be considered enough to characterize a true social
life, same in invertebrates.
