Simplocariini is a tribe of pill beetles ( Byrrhidae) comprising approximately 9 and more than 40 described . The tribe was established by Mulsant & Rey in 1869 and is classified within the Byrrhinae. Members of this tribe share the family characteristic of conglobation—the ability to roll into a ball when disturbed. The tribe includes genera distributed across the Holarctic region, with some genera showing more restricted geographic ranges.

Identification
Simplocariini can be distinguished from other tribes in Byrrhidae by combinations of morphological characters including antennal structure, prosternal process shape, and elytral surface sculpturing. The tribe is characterized by having antennomeres that are relatively short and compact compared to some other byrrhid tribes. Members of the Simplocaria, the type genus, have distinctive elytral and punctation patterns. Separation from the tribe Byrrhini often requires examination of the prosternal process and the form of the antennal club.

Distribution
The tribe Simplocariini has a primarily Holarctic distribution. Individual show varying ranges: Simplocaria is widespread in the Palearctic and Nearctic regions; Exomella, Lioligus, and Lioon are Nearctic; Lasiomorychus and Trichobyrrhulus are Palearctic; Himalayoligus is restricted to the Himalayan region; Horiella is found in Japan; and Chrysosimplocaria has a more limited distribution.
