Opas is a genus of long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1896.[2] Though few males have ever been studied, they are much smaller than females. Their pedipalps have a paracymbium, and a conductor that projects from the tegulum, enclosing the embolus.[3] They sit at the center of orb-shaped webs, many attached to low plants. Their webs are relatively flat, though rotated 45 degrees from horizontal.[3] It has previously been synonymized with Leucauge.[4]
Species
(As of November 2019) it contains six species, including four that were transferred from Mecynometa, found in the lower half of the Americas:[1]
