equivalent to tribe Achurumini
Identification
Only one North American genus, Achurum, is included. It has been associated with other Toothpick Grasshopper genera, but all others in North America except Metalpea (others are in subfamily Leptysminae or the Mermiria group) have at least a low tubercle between the base of the front legs and no spines pointing back from the "knees" of the hind legs. Metaleptea is included in a different subfamily in tribe Hyalopterygini, and differs primarily in the much stockier build of the insects. Achurum should probably be included in the Hyalopterygini, but it differs from members of that group in having the stridulatory apparatus characteristic of subfamily Gomphocerinae (absent in Hyalopterygini), so it has been grouped in this subfamily.
