The identification of all specimens (5 males, 1 female) of the rare water scavenger beetle Laccobius simulatrix recorded recently in the Czech Republic was revised. The revision showed that 4 specimens are virtually immature specimens of the species Laccobius striatulus (Fabricius, 1801). The identification features of these specimens are not distinct and furthermore their male genitalia are slightly misshaped and thus they are similar to the not much precise illustrations of the aedeagus of L. simulatrix, which are published in the commonly used keys to the identification of the hydrophilid beetles in the Central Europe. To enable the identification a more accurate drawing of the characteristic male genitalia of the species L. simulatrix is given in this paper. All data regarding the occurrence of L. simulatrix in the Czech Republic are summarized and shown in the map.
