The TCS 2 Task Group will turn TCS into a form in which it can be maintained. The new version of TCS will be a vocabulary standard like Darwin Core and Audiovisual Core and will complement these other existing TDWG standards.
A loosely defined group of species. Zoology: 'Aggregate - a group of species, other than a subgenus, within a genus. An aggregate may be denoted by a group name interpolated in parentheses.' -- The Berlin/MoreTax model notes:'[these] aren't taxonomic ranks but cirumscriptions because on the one hand they are necessary for the concatenation of the fullname and on the other hand they are necessary for distinguishing the aggregate or species group from the microspecies.' Compare subspecific aggregate for a group of subspecies within a species!
