Silvanidae
Silvan Flat Bark Beetles, Silvanid Flat Bark Beetles
Silvanidae is a family of small beetles in the superfamily Cucujoidea, comprising approximately 68 genera and 500 described species. Members are found on all continents except Antarctica, with highest diversity in the Old World tropics. The family is divided into two subfamilies: Brontinae (larger, loosely jointed beetles with long antennae and mandibular mycangia) and Silvaninae (smaller beetles with closed procoxal cavities). While many species inhabit subcortical environments under bark, several genera have become economically significant stored product pests.
Taphroscelidia
Taphroscelidia is a genus of small beetles in the family Passandridae, first described by Crotch in 1873. The genus contains approximately 13 described species distributed across multiple continents. Members of this genus are classified as flat bark beetles, a group associated with woody substrates. The genus has been documented through 192 observations on iNaturalist, indicating moderate but widespread recording effort.
