Diagnosis. Males of E. perfidus comb. nov. are recognized by the male palp tibia for having a dorsal projection with a bifid apex, with two flattened tips, which fit into the cymbium concavity. Females possess the epigynum with large and protruding plaque with curved sides, much narrower in front than in the back (Figs 8, 9).
Transference and synonymy: Detailed study of the Tenedos perfidus type material collected in Mato Grosso (MCP 2545 and 2546) showed that specimen has the diagnostic characteristics of the genus: posterior eye row strongly procurve, medium and lateral posterior spinnerets fused in the females and the total absence of these spinnerets in the males, exhibiting the typical morphology of Epicratinus. Examining the description of E. santacruz (see Grismado & Izquierdo, 2016) and the available material type of Epicratinus perfidus, showed that these species have the same diagnostic characteristics and are herein considered synonyms.
