Miturgidae

Belongs within: Dionycha.

The Miturgidae are a group of ecribellate spiders with two-segmented posterior spinnerets (at least laterally). Membership of the family has historically been contentious, and Ramírez (2014) synonymised it with the previously recognised family Zoridae. This redefined clade is supported by features of the male palps, including a retrolateral cymbial groove, a median apophysis continuous with the embolus with the base directed forwards, and a partially membranous retrolateral tibial apophysis bearing a canal. Most genera, excluding Teminius, have the piriform spigots of the spinnerets larger in males than in females (Ramírez 2014). The genus Miturga has the eye-rows nearly straight whereas in Zora they are strongly recurved so the anterior lateral eyes are closer to the posterior median eyes. Parallel eye rows are also characteristic of the Indo-Australian Systariinae which also have tapering anterior lateral spinnerets and a deep thoracic groove.

Characters (from Ramírez 2014): Legs with two claws. Male palp bearing retrolateral tibial apophysis, usually with a canal and a membranous area; retrolateral groove usually present on cymbium; embolus arising centrally on tegulum, with median apophysis arising in a continuum from its base, directed forward.
