Cyanomethia pseudothonalmus Philips and Ivie was known only from the single male holotype. Recent collection of additional specimens from St. John, Virgin Islands, allowed the description of the previously unknown female. Information on the biology of this species is also given. The two unique specimens used to describe Methia taina Zayas and Tessaropa luctuosa Zayas from eastern Cuba were restudied, and the former is considered to be the female of the latter. Therefore, M. taina is considered a junior synonym of Tessaropa luctuosa Zayas, new synonymy. A damaged and enigmatic specimen illustrated in the literature was studied and placed in Tessaropa Haldeman as an undescribed species.A new key to genera of West Indian Methiini is provided.
