Culicoides charruus Spinelli & Martinez (1992), is known from Paraguay, Argentina y Uruguay. The pupa was partially described by Spinelli & Martinez, and Spinelli et al., (1993). Ronderos et al., (2008) described larva of C. charruus, and redescribed the pupa more fully, and provided data on the life cycle and locomotion of the larva, based on inmatures collected from water accumulated in the leaf axils of Eryngium pandanifolium.
