  DISTRIBUTION.-  Africa, Tropical America.

 

  TAXONOMY.-  The systematics of this genus is very unsettled at present.  There is a large number of species in Africa and tropical America.  The genus has received a great deal of study because of its importance as intermediate hosts for human schistosome parasites.  However, many species not directly implicated as schistosome hosts remain poorly studied.  Subdivision of Biomphalaria into subgenera is not plausible at present.

  DISTRIBUTION RECORDS.-  Widely distributed in the West Indies, Mexico and Guatemala.  Bequaert & Miller (1973) state that the species apparently has a continuous distribution over Mexico.  NICARAGUA, Dept. Managua: Lago de Xiloa (12°14’ N, 86°20’ W) (Thompson & López, 1996); abundant records from the Pacific versant (Pérez & López, 2002). GUATEMALA, Dept. Alta Verapaz: Chama (Hinkley, 1920). Dept.

  TAXONOMY.-  Recognition of Gastrocopta pellucida hordeacella (Pilsbry, 1890) as a valid subspecies is controversial.  Bequaert & Miller (1973) synonymised both hordeacella and parvidens with Gastrocopta pellucida pellucida (Pfeiffer, 1941).  Later, Smith, et al, 1990, resurrected hordeacella as a distinct subspecies.  Bifidaria hordeacella parvidens (Clapp, 1899) is a synonym of hordeacella.  I follow these authors by assigning all mainland populations to hordeacella.
