Members of this genus are small, typically 1-2 mm in length, with reduced wing venation characteristic of many Encyrtidae. The genus has a distribution with records from North America, Asia, and other regions. Species of Adelencyrtus have been documented as important agents against insect pests in agricultural and horticultural systems.
