 back to About Taxonomic & Geographic ScopeOncid ID is limited taxonomically to the adult form of the "twig girdlers," a large group of longhorned beetles in the tribe Onciderini (Cerambycidae: Lamiinae). The tribe currently contains 79 genera and ~450 species. Several lamiine taxa native to the Afrotropic (e.g. Prosopocerini, Sternotomini) and Australasian regions (e.g. Polyacanthia sp.) share many characteristics with Onciderini. However, these taxa are not known to girdle branches and have never been proposed as members of Onciderini. As such, they are not treated in Oncid ID. A formal taxonomic revision and phylogenetic analysis is needed to investigate the relationships among these taxa.Geographically, Oncid ID is restricted to the natural range of the twig girdlers, the Nearctic and Neotropical regions. Onciderini are widely distributed from the USA, through all countries in Central and South America. In the Antilles, they are known from all countries/territories in the region EXCEPT: Antigua and Barbuda, Anguilla, Aruba, Bahamas, British Virgin Islands, Cayman Islands, Netherlands Antilles, Saint Barthelemy, Saint Kitts and Nevis, Saint Martin, and Turks and Caicos Islands. Although two twig girdlers were originally described from Chile in 1859, this is likely an erroneous record as no members of this group have been collected there since (J.E. Barriga, pers. communication). See Bezark & Monné, 2013 for current classification and geographic distribution. |
