Wi & al. (2013, p.415) underline many species of Corycaeidae are not adequately studied based on these detailed identification keys. This fact can cause erroneous identification when used in different areas, because sister and sibling species from different geographic regions may not be considered for their morphological variations or /and differences. | | * We thank Ruth Böttger-Schnack (Universität Bremen) for having forwarded to us a copy of the families Corycaeidae, Oncaeidae et Sapphirinidae from the Fauna of Japan by Chihara et Murano (1997), as well as the English translation concerning the Oncaeidae family performed by Hiroshi Itoh. |  Issued from : F.
