In this paper is reported for the first time the occurrence of Panstrongylus lignarius in the State of Mato Grosso. From 2001 to 2009, five specimens were caught in the municipalities of Paranaíta, Alta Floresta, Lucas do Rio Verde, Sorriso and Guarantã do Norte, and sent to the Laboratório de Entomologia da Secretaria de Estado de Saúde de Mato Grosso where they were identified as Panstrongylus lignarius (Walker, 1837). The presence of this species in the state of Mato Grosso, Brazil expands its geographical distribution.
