BenchTaxonName
|
| ||||||
sp. nr. | 1) Means "species near" | ||||||
cf. | 1) Means "confer" | ||||||
/ | 1) Used to denote two or more taxa that are unresolvable or where only two taxa are known in a monophyletic group | ||||||
sp. 1 or sp. A | 1) Refers to provisional taxa reported in the literature where their specific identity remains unknown; also known as "operational taxonomic units" or "OTUs" 2) Provisional designation is reported exactly as it appears in the literature 3) A BenchTaxonNameReferenceCode is required to support this type of name | ||||||
sp. 1 ? | 1) Genus names followed by "sp. 1 ?", "sp. 2 ?", "sp. 3 ?", etc. refer to unique species within the sample, but the species name (epithet) has not been determined. 2) These designations are used for taxa that are rare in a sample and may not be identified with confidence. These names are to be used to determine the number of unique taxa within a sample. That is, the names distinguish taxa that are different within a sample, but not across samples. For example, Sample #1 contains Navicula sp. 1 ?, Navicula sp. 2 ? and Navicula sp. 3 ?, which are 3 undistinguished species within the sample. If Sample #2 also contains Navicula sp. 1 ?, this taxon may (or may not) be the same as in Sample #1. 3) NOTE that within a sample with only one unknown species in "Genus", Genus sp. is equivalent to Genus sp. 1 ? | ||||||
group | 1) Denotes a group of more than two closely related species that cannot be separated or organisms that can be reliably placed in a species group where determination to species is unsupported | ||||||
complex | 1) Denotes a species for which there may be considerable variation suggesting two or more cryptic species | ||||||
n. sp. | 1) Means "new species" | ||||||
Other conditional or provisional designations | 1) Reported exactly as they appear in the reference from which they were obtained |
