Midway Islands
The Midway Islands are a territory of the United States of America and are protected as a national wildlife refuge (fws.gov).
Marine molluscs known only from Midway include a wentletrap Claviscala midwayensis (Eddie Hardy) and a top snail Astele (or Omphalotukaia) midwayensis (ndap.org.tw). Arthropods that have been collected solely from Midway include a long-legged fly Dactylomyia vockerothi (Bishop Museum pdf file) and several mites from the non-endemic Laysan Albatross including Neoschoengastia gettmani (IngentaConnect), Neotrombicula megensi (Bishop Museum), and Scapheremaeus fisheri (Bishop Museum).
