The current problem with complexes now is that the name has to be the type species; example being Gray Tree Frog in which the scientific name is the type specimens. Confusion with this method might be, because two taxa are named the same, how many observers are going to mistakenly submit to the wrong taxa. One of the solutions offered is to ensure the complex has an English name clarify it’s a complex but I wonder if the following is better.
Many taxonomists have often used brackets or parentheses to describe superspecies. For example, someone who believes the Horned Lark is one of many species may call the European populations Eremophila [alpestris] penicillata or a person who believes the McKay’s Bunting is not a real species may call it Plectrophenax [nivalis] hyperboreus. eBird often uses brackets to summarize field-identifiable subspecies groups like the Oregon Junco Junco hyemalis [oregonus] to indicate the person is referring to the 6 subspecies instead of the type subspecies.
Insect taxonomists use parentheses to describe species with subgenera as their parent. Orthoptera Species Files (OSF) refers to a cricket species as Gryllus (Homaloblemmus) zambesi to indicate that though it’s a part of the subgenera Homaloblemmus, its scientific name is still Gryllus. They also refer to species groups in this manner, such as Melanoplus (sangunipies). I think implementing this into complexes will help keep them erroneous identifications but I’d curious as to opinions to this.
