Neolimnophila alaskana (Alexander, 1924) stat. nov., a species new to the Palaearctic Region (Diptera: Limoniidae).

The Nearctic Neolimnophila ultima ultima (Osten Sacken, 1860) is proposed as a new junior synonym for the Palaearctic N. placida (Meigen, 1830). Neolimnophila ultima alaskana (Alexander, 1924) is elevated to species rank and reported in the Palaearctic Region for the first time. Redescriptions of N. carteri (Tonnoir, 1921), N. placida, and N. alaskana stat. nov. are provided and their male terminalia and wing venations are illustrated. [ABSTRACT FROM AUTHOR]
