Diagnostic combination.

Elegant Canopy Beetles

During evolution toward a canopy domain and away from a likely under canopy sister group, Agra adults acquired numerous generic-level autapotypic features as follows: head elongate with prognathate mandibles, securiform labial ultimate palpomeres (Erwin 1982a), extended cranium, and constricted neck; prothorax elongate and tubular, plural sutures effaced; tarsomeres (Erwin 1982a) dilated with setiferous pads beneath, claws explanate and pectinate; elytron with latero-basal sinus and latero-apical callus, apex medially and laterally toothed or somewhat produced, apical margin truncate, sinuate, or medially lobed; and male venter variously adorned with setal or pubescent patches; female reproductive system adapted to egg-laying deep in substrate (telescopic) (Erwin 2002) with (usually) stout, apically-armed with ensiform setae, stylomere 2. Defense system very large (Erwin 1982). Size. ABL=6.0mm to 29.0mm; TW=1.5mm to 6.0mm.
