There are 214 species of the suborder Tipulomorpha (Diptera) known from Panama. Of these, 162 species were described by the noted American entomologist, Charles Paul Alexander, from Panama during the period from 1912 through 1979. Panama hosts two of the four families found within the Tipulomorpha: Limoniidae (197 species) and Tipulidae (17 species). We have records of only three species from multiple provinces (n = 2) within Panama and 211 species from just one province. The vast majority of the latter are known from a single location within their respective provinces. There are 142 endemic species (66.4%) included in Panama’s Tipulomorpha fauna, with the remainder being found elsewhere in South America (48 species), Central America (44), Mexico (23 species), the Caribbean (14 species), and the United States (4 species). Whereas, this taxonomic group has benefited from collecting in the Canal Zone and the popular western highlands in Chiriqui Province, we know little or nothing of the distribution of species within the country, their natural history, or their relationship to water quality.
Two female specimens of the Neotropical genus Ophionthus Bernhauer were found during museum collection surveys, representing different species of the genus. These species are Ophionthus serpentinus Bernhauer, 1908 and O. asenjoi sp. nov. The genus Ophionthus was monotypic until the present study and only known from a single male specimen from Central Peru. The genus is redescribed with the inclusion of female characters from both the type species and the new species here proposed. Additionally, the systematic position of Ophionthus within the Neotropical lineage of Philonthina and its geographical distribution in Peru are reassessed. Descriptions, diagnoses, illustrations, pictures, a cladogram, and a distribution map are provided.
