The utility of wing morphometrics for assigning type specimens to cryptic bumblebee species
Abstract Since the beginning of taxonomy, species have been described based on morphology, but the advent of using semio‐chemicals and genetics has led to the discovery of cryptic species (i.e. morphologically similar species). When a new cryptic species is described, earlier type specimens have to...
