1) Means "species near"
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"
|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 ?
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
1) Denotes a species for which there may be considerable variation suggesting two or more cryptic species
1) Means "new species"
Other conditional or provisional designations
1) Reported exactly as they appear in the reference from which they were obtained
