Arnett, p. 160, lists 11 spp. (1)Size Circa 21-45 mm (A. oblongifolia 40-45 mm) Identification Compare Microcentrum and Scudderia. Amblycorypha has long legs (hind femora extent almost to tips of tegmina) like Scudderia, but more rounded wings. Amblycorypha has overall shape of Microcentrum, though rather more rounded, esp. female. Especially the tip of the forewings (tegmina) in Amblycorypha is more rounded than in Microcentrum. Top of the head rounded, strongly deflexed. Green, but some species, esp. A. floridana, have a pink phase. Some species have a yellow phase as well! This genus has a wide space between base of antennae, apparently distinctive, and differntiates from Microcentrum, Scudderia.
Stridulatory apparatus of some male Amblycorypha is very large.
