Pseudomyrmecinae is a small subfamily of ants containing three genera of slender, large-eyed arboreal ants, predominantly tropical or subtropical in distribution.

[1] In the course of adapting to arboreal conditions (unlike the predominantly ground-dwelling myrmeciins), the pseudomyrmecines diversified and came to occupy and retain a much wider geographic range.

[2] Pseudomyrmecines consists of 230 described species in three genera.

Among those, 32 species live in plant domatia, making them the most diverse plant-occupying ant group worldwide.
