Genus Ilargus Simon, 1901

Diagnosis. Medium sized spiders with various color and marking patterns. Chelicera with two promarginal teeth and one unident retromarginal tooth. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs. Male palpal bulb large and wide, with obvious proximal tegular lobe; embolus usually long and coiled; retrolateral tibial apophysis finger-like. Epigynal window present with a median septum. Spermatheca swollen.

Similar in body form to Coryphasia , but differs in the one unident retromarginal tooth on chelicera ( Coryphasia has one bicuspid retromarginal tooth) and the absence of the second spermathecae in the vulva.

Remarks. Three species have been reported from South America ( Platnick 2012), of which only the type species, Ilargus coccineus Simon (see Simon 1901b) has been well documented ( Galiano 1963; Edwards et al. 2005). However, Ilargus is much more diverse than that. Here we describe six new species discovered during expeditions to Ecuador. The placement of these species in Ilargus is partly based on unpublished molecular data.
