[Mary Barkworth]

Are Tetraponera continua and T. penzigi continua synonyms? Both are listed with (Forel, 1907) as the author citation - Catalogue of life accepts the subspecies version but does not list synonyms.
I am trying to ensure that all names of insects known to GBIF from the core of the Horn of Africa (Djibouti, Somaliland, Somali Region of Ethiopia, and Somalia) are in OpenZooMuseum - hence my interest.
