A second update to the checklist of Finnish long-legged flies (Diptera: Dolichopodidae), with a re-evaluation of the status of Hydrophorus callosoma Frey, 1915

Abstract

Eighteen species of long-legged flies (Dolichopodidae) are reported as new to Finland. A further species, Microphorella praecox (Loew), is confirmed as a Finnish species. The status of Hydrophorus callosoma Frey, 1915 is re-evaluated and a lectotype is designated for the species. Hydrophorus albosignatus Ringdahl, 1919 is found to be a junior synonym of Hydrophorus callosoma (syn. n.). Characters for identifying both sexes of Hydrophorus callosoma and Hydrophorus altivagus Aldrich are presented and illustrated with high-quality photographs.

Checklist of the Empidoidea of Finland (Insecta, Diptera)

“…The Finnish species were last listed by Kahanpää and Winqvist (2005) for Atelestidae, Brachystomatidae, Hybotidae and Empididae (plus Microphorinae) and by Kahanpää and Grichanov (2004) for Dolichopodidae. Two updates to the dolichopodid checklist have since been published (Kahanpää 2006, 2013). …”
