Troschel 1849: Sultana (Sultana) sultana (Dillwyn, 1817) [r]; Strebel and Pfeffer 1882: Sultana (Metorthalicus) atramentaria (Pfeiffer, 1855) [g, m, r], Sultana (Sultana) sultana [g].

Remarks.

We follow herein the classification of Schileyko (1999), awaiting further morphological and molecular studies to ascertain the systematic position of this genus. The record for Panama is based on unverified museum collections. Contrary to Schileyko (1999: 362) we are not aware of any sinistral Sultana species.
