What is "caponia"

The Eight-eyed orange lungless spiders (genus Caponia) is an Afrotropical genus of spiders, that breathe through two pairs of tracheae, rather than book lungs. They are agile, nocturnal hunters, that hide by day in a variety of silk-lined retreats. They have a tightly-arranged set of eight eyes, as opposed to the related genus Diploglena, where only two eyes are present.
