Revision of the Genus Listroptera Audinet-Serville and Description of Aguassay, New Genus (Coleoptera, Cerambycidae, Cleomenini)

The genus Listroptera Audinet-Serville (type species Callidium tenebrosum Fabricius) is revised and the following species redescribed: L. tenebricosa (Olivier) and L. carbonaria Chevrolat. Aguassay, new genus, is described based on Cerambyx collaris Klug, up to now belonging to Listroptera. Aguassay collaris (Klug), new combination, is redescribed and its geographical distribution widened. A key to recognize the neotropical genera Dihammaphora Chevrolat, Haenkea Tippmann, Listroptera Audinet-Serville and Aguassay, all of which form a homogeneous group within the tribe Cleomenini, is also included.
