Abstract
The larval stages of Tricorythodes fictus Traver, T. cobbi Alba-Tercedor and Flannagan, and T. mosegus Alba-Tercedor and Flannagan are described for the first time based upon reared specimens. The rarely reported Asioplax dolani (Allen) is newly documented from the Austroriparian ecological region of Texas. Leptohyphes zalope Traver, known from the southwestern United States and much of Central America, is newly documented from the Caribbean Islands of Grenada and Tobago. This represents only the second leptohyphid mayfly known from both Continental America and the Caribbean region. Additional Caribbean records of Allenhyphes flinti (Allen) are also given.References
