Diagnosis. Males of Epicratinus dookan   sp. nov. are easily recognized by the long RTA with the pointed and curved tip facing the center of the cymbium, differing from E. petropolitanus   by having a dorsal projection at the base of the RTA. Females, vulva presents small reniform spermathecae with corner at the external upper, edges of the atrium like inverted jar shaped ( Figs 34 View FIGURE 34 , 35 View FIGURE 35 ).

Etymology. The specific epithet is a noun taken in apposition and is in reference to Count Dookan (Brazilian name), a fictional character in George Lucas film, “Star Wars”. Count Dookan is a character which wears a curved hilt of his lightsaber, as the curved dorsal projection at the base of the RTA.
