Genus Amphidraus Simon, 1900

Diagnosis. Small spiders. Chelicera with two promarginal teeth and one fissident retromarginal tooth of more than two cusps. Embolic disc with an additional process besides the embolus. Tegulum with an obvious proximal lobe. Retrolateral sperm duct loop not obvious. Retrolateral tibial apophysis usually large and complex in shape. Epigynum without window but with a pair of copulatory openings anteriorly. Copulatory duct short or long and convoluted. Amphidraus differs from other Neotropical euophryine genera by the unique male palpal structures. Amphidraus is similar to Marma Simon (see Galiano 1962a; 1963 a) in the cheliceral teeth pattern, but differs in the more delicate body form, the complex retrolateral tibial apophysis and the presence of a proximal tegular lobe on the male palp.

Remarks. Four species have been reported from South America ( Galiano 1962, 1963, 1967, 1976; Platnick 2012). A new species from Ecuador is described here.
