Kryptochroma: a new genus of bark-dwelling crab spiders (Araneae, Thomisidae)

A recent phylogenetic analysis has shown that the genus Stephanopis comprises several different lineages of bark-dweller crab spiders. The ones with South American distribution that present a close relationship with other Neotropical genera like Epicadus, Onocolus, Rejanellus and Epicadinus were re...
