(Acrdidoxenini) Mecopodinae are a subfamily of bush crickets found in western South America, sub-Saharan Africa, and Asia.

In Asia, the distribution includes India, Indochina, Japan, the Philippines, and Malesia to Papua New Guinea and Australasia, including many Pacific islands.

[2][3] Mecopodinae are characterized by their leaf-like forms, but are sometimes called "the long-legged katydids".

[citation needed] It is a paraphyletic grouping that is part of the Phaneropteroid clade: sister to Phaneropterinae and Pseudophyllinae.

[3] Although as of December 2018[update], Orthoptera Species File places Mecopodinae within the family Tettigoniidae, the family Phaneropteridae has been recommended for reinstatement,[4] with subfamilies Mecopodinae, Pseudophyllinae, Phyllophorinae, and Phaneropterinae.
