Remarks. 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).
