Wyeomyia pertinans (Williston 1896)

Wyeomyia (Wyeomyia) pertinans (Williston)

This species was described from St. Vincent, and the only specimen in the United States National Museum is a syntype female. It has been reported also from Barbados, Grenada, and St. Lucia, and with some degree of certainty from Jamaica, Trinidad, Tobago, Central America, and Mexico with varying degrees of doubt. Until males can be studied from all of the areas these doubts will remain. As all the specimens listed below are females, identification cannot be certain either, but the geographical distribution and agreement with the original specimen makes the determination probably correct. Nothing is known of the biology of this species.

Three larvae were collected from bromeliads, but these were not associated with adults and cannot be determined.
