Aprosphylini

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.

Mecopodinae are characterized by their leaf-like forms, but are sometimes called "the long-legged katydids". It is a paraphyletic grouping that is part of the Phaneropteroid clade: sister to Phaneropterinae and Pseudophyllinae. Although as of December 2018, Orthoptera Species File places Mecopodinae within the family Tettigoniidae, the family Phaneropteridae has been recommended for reinstatement, with subfamilies Mecopodinae, Pseudophyllinae, Phyllophorinae, and Phaneropterinae.
