Mezirinae
flat bugs
Mezirinae is the largest of (), comprising over 1,120 described across 124 with global distribution. Members are primarily found under bark of decaying wood in forest . The subfamily includes both (fully winged) and (short-winged) genera. Phylogenetic studies based on mitochondrial confirm Mezirinae as and highly derived, sister to a clade containing Carventinae and Aneurinae.
Habitat
Primarily inhabits the underbark of decaying wood in forested environments. Specific records include wet forests with decaying fallen wood and dead branch bark, at elevations such as 335m in the Tibet Autonomous Region.
Distribution
Global distribution, with particular diversity in the Oriental region (over 57 ). Documented from China (Yunnan, Tibet), Myanmar (Burmese amber, Cenomanian), and Dominican Republic (Dominican amber, Miocene). Specific collection localities include Lushui (Sanhe Village, Yunnan) and Motuo County (Yigongbai Village, Dexing Town, Tibet Autonomous Region).
Diet
Has been observed to feed on the mycelia of rotting wood.
Behavior
Often lives in groups under bark.
