Abstract

A checklist of 112 species of shore flies (Ephydridae, Diptera) recorded from Finland is presented. Comparing this to the list of Hackman (1980), 52 changes are made: 25 species are added (all but one recorded after 1980), 18 misidentifications are deleted, 5 junior synonyms are replaced and 5 updated generic combinations are given.

Introduction

Shore flies (Ephydridae) are dark coloured, dull to shining, 1–6 mm long flies. Most species develop in aquatic or semi-aquatic conditions, feeding of algae, bacteria, yeasts or even decaying animal matter and excrements; or they are phytophagous and mining in leaves or stems. The group is divided into 5 subfamilies and 19 tribes (Zatwarnicki 1992), of which 15 could potentially be found in Finland.

Hackman (1980) originally listed 105 species. Zatwarnicki (1997) corrected the synonymy and generic placement of some species. Compared to Hackman (1980) the present list adds 25 species and removes 18 misidentified species (mostly Hydrellia). Five junior synonyms in Hydrellia, Philygria, Scatella and Scatophila are replaced; four species of Ditrichophora are combined with Gymnoclasiopa and one species of Lamproscatella with Haloscatella. Two species are endemic for Finland: Psilopa nitidifacies Frey, 1930 (note that this was omitted by Hackman 1980), and Gymnoclasiopa psilopina (Frey, 1933).

Nomenclature follows the current version of the Ephydridae section of Fauna Europaea (Zatwarnicki 2013). The subfamilies and the tribes are ordered systematically; genera within tribes and species within genera are listed alphabetically.

Number of species:

World: 1927 species and 63 nomina dubia (as of February 2014)

Europe: 340 species and 3 subspecies (Zatwarnicki 2013)

Finland: 112 species

Faunistic knowledge level in Finland: average

Notes

Gymnoclasiopa aurivillii (Becker, 1896) is probably a junior synonym of Gymnoclasiopa nigerrima (Strobl, 1893).

Hydrellia. At least two additional species occur in Finland but their proper names are still under investigation.
