  • A group of organisms that are morphologically distinct from other organisms.
    species
    1953

    A group of specimens which is considered sufficiently different morphologically from the most closely related forms known, to be given a specific name […] morphospecies

    The morphospecies (morphological species) as a “group of specimens which is considered different morphologically from the most closely related forms known”, or more narrowly as a species “established solely on morphological evidence”, is not in itself essentially different from a chronospecies or a biospecies, both of which use morphology as a guide to relationship (the chronospecies in particular being founded solely on the biometrical integration of morphological data). It is a commonplace that in fact almost all species of whatever kind are morphological species in greater or lesser degree.

    1956

    A morphospecies in palaeontology is a species which is defined on morphological characters and in this respect at least resembles both biospecies and chronospecies, since they too are largely or completely based on morphological criteria.
