Liotrichus falsificus

Distinguished from other elaterid genera by the dense, fine pubescence characteristic of Liotrichus. Separation from congeners requires examination of subtle morphological features such as antennal structure, pronotal shape, and male genitalia; specific distinguishing characters for L. falsificus versus other Liotrichus species are not readily available in general sources. The species name 'falsificus' (meaning 'counterfeited' or 'falsified') may allude to resemblance to another taxon.

Adults are click beetles with the family's characteristic elongated, parallel-sided body form and pronotum bearing backward-pointing posterior angles. Members of genus Liotrichus are recognized by their dense covering of fine, hair-like setae (pubescence) giving a somewhat velvety appearance. Specific coloration and size for L. falsificus are not well documented in available sources.

Eastern Canada: recorded from New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, and Quebec.

Adults possess the elaterid clicking mechanism: a prosternal process that engages with a mesosternal cavity to produce a sudden snap, enabling the beetle to right itself when on its back.

• Other Liotrichus speciesShare the diagnostic dense pubescence; require detailed morphological examination to distinguish, particularly of male genitalia and antennal serration.
• Other Elateridae generaLack the dense, fine pubescence that characterizes Liotrichus; body surface generally smoother or with sparser, coarser setation.
