Description of a new genus and twelve new species of marine bivalves from tropical West Africa, with comments on other taxa from the area

Twelve species of marine bivalves from tropical West Africa are described: Glans afra n. sp., Crassatina guineensis n. sp., Diplodonta (Felania) nizeryi n. sp., Kurtiella zabii n. sp., Moerella leloeuffi n. sp., Donax (Machaerodonax) pseudacutangulus n. sp., Microcirce anteai n. sp., Pitar nicklesi n. sp., Pitar (Costellipitar) longior n. sp., Pholas (Thovana) bissauensis Cosel & Haga n. sp., Pholadidea eborensis Cosel & Haga, n. sp., Barnea (Anchomasa) ghanaensis Huber, n. sp. The new genus Huberimactra is proposed for two species hitherto included in Anatina Schumacher, 1817. The type species of the tellinid genus Atlantella Huber, Langleit & Kreipl, 2015 is shown to have an internal portion of the ligament and a hinge configuration similar to Moerella Fischer, 1887, and the two taxa are therefore held as synonyms. The species Atlantella ryalli Huber, Langleit & Kreipl, 2015 is consequently considered as a synonym of Moerella donacina (Linnaeus, 1758). The specific name cumana, currently in usage in the combination Macomopsis cumana (O.G. Costa, 1830) is declared nomen protectum against the senior synonym Tellina pellucida Spengler, 1798, declared nomen oblitum under provisions of ICZN art. 23.9
