Front and middle tibiae flat or sulcate dorsally (convex or round in Microcentrum), also ridged or raised laterally, have long legs (hind femora extent almost to tips of tegmina) like Scudderia, but more rounded wings, and overall shape of Microcentrum, though rather more rounded (esp. tegmina), esp. in ♀♀. Top of the head rounded, strongly deflexed. Green, but some species, esp. A. floridana, have a pink phase (some have a yellow phase as well)
wide space between base of antennae apparently differntiates from Montezumina, Turpilia, Inscudderia, Scudderia, shared with Microcentrum

Stridulatory apparatus in some males is very large
