Review of fungus gnats of the genus Tarnania Tuomikoski, with a phylogeny of the Rymosia s.l. genus group (Diptera: Mycetophilidae)
Abstract The four known species of Tarnania Tuomikoski are reviewed, viz. T. dziedzickii (Edwards, 1941), T. fenestralis (Meigen, 1818), T. nemoralis (Edwards, 1941), and T. tarnanii (Dziedzicki, 1910). Males and females are re-described, photographed and their terminalia figured. An attempt is made...
