Abstract

The genus Rosella Whitehead was formerly known only from its type-species, the Costa Rican R. sickingiae Whitehead, a seed predator of Sickingiae maxonii (Rubiaceae). Lignyodes triophori Gyllenhal from Brazil is transferred to Rosella, redescribed, illustrated, and included in a key distinguishing it from R. sickingiae and from R. arcuata from Panama and Colombia which is described and illustrated as new.
