Connecting terms for taxonomic categories as in abbreviated words that may appear between other words in older species-group names.
For example "var." in Pheidole variabilis var. redunca.
It's not possible to add or update protonym names unless all abbreviations are on the allow list in the source code. If that's the case, omit the unknown abbreviations and let me or someone know and we will add it to the list.
See Lingafelter & Nearns, 2013 to determine whether a species-group name originally formed as a trinomen is infrasubspecific or subspecific. In summary, they conclude "the terms "aberration", "ab." and "morph" always denote infrasubspecific status. The terms "variety" or "form" (including use of the terms "var.", "forma", "v." and "f.") only denote infrasubspecific status if they are published after 1960. Before 1961, the terms "variety" or "form" (including use of the terms "var.", "forma", "v." and "f.") only denote infrasubspecific status if the author expressly gave it that status, based on 45.6.4."
|ab.||abberratio, aberrant form|
