According to the EPPO (2007) known from Madagascar as introduced synanthropic species T. granarium Everts , the species is not included in the presented key. The mentioned species visualy similar to species belonged to the genus Paratrogoderma Scott, 1926 , but the genus differs from the genus Trogoderma by the 10- segmented antennae (see Háva 2008).
