Amphicnaeia Bates, 1866

Amphicnaeia is very similar to Rosalba, differing by the presence of long, erect setae on the elytra, which are absent in Rosalba . It is also characterized by a slender body, retractile head, slightly elevated antennal tubercles, filiform antennae, antennomere III shorter than IV (rarely very slightly longer), laterally unarmed prothorax (one species with a very small tubercle), and metaventrite not reduced.
