(2004b)recorded it for the first time from Brazilfrom the state of Mato Grosso. Later, this species was recorded from the states of Rondônia( Salles et al., 2005), Roraima(  Falcão et al. 2011) and Piauí( Boldrini et al., 2012). Nieto et al. (2011)recorded this species for the first time from Venezuela. As in  Falcão et al. (2011), we found differences in relation to the number of denticles on the tarsal claws as originally described by Dominique et al. (2001), with 21 denticles on tarsal claws.  Falcão et al. (2011)found one nymph with 8 –9 denticles, and we have also found the same variation in two nymphs in the material from states of Minas Geraisand Espírito Santo. As in  Falcão et al. (2011), we are considering this as an intra-specific variation.    Distribution. FRENCH GUIANA; VENEZUELA; BRAZIL: states of Mato Grosso, Piauí, Rondôniaand Roraima. NEW RECORDS: Espírito Santoand Minas Gerais.    Material examined.  Threenymphs mounted on slides, BRAZIL,  Minas Gerais, Pingo da Água, Rio Sacramento, 19º49’S/ 42º18’W,  29.x.2005, Francischetti, C.
