The new genus and species Makoiamya cotterallae is erected for fossil bivalves previously informally identified as Anodontophora Alberti (= Unionites Wissmann) or a relative or Ochotomya Polubotko in the Late Triassic Murihiku Terrane of New Zealand and Téremba Terrane of New Caledonia (Norian and Rhaetian; Warepan and Otapirian local stages). Neither of these genera happily accommodates these shells and a new genus is considered necessary for them. Makoiamya fits most readily into the Ceratomyidae and members were burrowers in fine sand and silt, where they are generally preserved in life orientation.
新属种马科伊亚蛤（Makoiamya cotterallae）是为先前在新西兰晚三叠世穆里希库地体和新喀里多尼亚特伦巴地体（诺利阶和瑞替阶；瓦雷潘阶和奥塔皮里阶地方层位）中被非正式鉴定为阿尔贝蒂无齿蛤（Anodontophora Alberti = 维斯曼蚌属Unionites）或其近缘种，或波卢博特科奥乔托蛤（Ochotomya Polubotko）的化石双壳类而建立的。这两个属都不太适合容纳这些贝壳，因此认为有必要为它们建立一个新属。马科伊亚蛤最容易归入角蛤科，其成员是细沙和淤泥中的穴居者，它们通常以生活姿态被保存下来。
