One of the most successful, in terms of biodiversity and distribution, but least studied groups of tenebrionids is the tribe Asidini. The asidine darkling beetles are a large tribe of flightless midsized (4.5mm-35mm) tenebrionids found in many arid and semi-arid regions around the world. Currently the tribe contains approximately 1000 described species in 46 genera divided into four geographically isolated monophyletic clades (Doyen 1993). The North American component of the tribe alone contains over three hundred species and subspecies in 27 genera and makes up approximately 20% of the total North American tenebrionid fauna (Aalbu et al. 2002).

About searches and results. Taxon Pages with various amounts of content are returned for all taxa listed under the Browse option. The Search option returns either a taxon page (where available) or a report with nomenclatural details for all taxonomic names now entered in our database. When a taxonomic name is associated with more than one taxon (ie., differing concepts), the Search option will return a disambiguation page allowing for the further selection among possible taxon pages. Taxon pages and nomenclatural data for the species group, now in preparation, will eventually be accessible under the valid genus (Browse option) or directly through the Search option. To locate a name quickly in the Browse option, use the find option of your browser [Control or Command + F]. The Taxon Pages are a dynamic work in progress. Please contact us to pose suggestions or corrections.

About this search: You are searching through the nomenclature in this project. When a taxonomic name record is associated 1:1 with a taxon page the search result will direct you to that taxon page. When the taxonomic name is not associated with a taxon page a report with nomenclatural details of the search result is returned. When a taxonomic name record is associated with many taxon pages (e.g. differing concepts) the search result returns a disambiguation page allowing for the furter selection of possible taxon pages.
