Abstract

A revised checklist of the Chamaemyiidae and Lauxaniidae (Diptera) recorded from Finland is presented.

Keywords

Checklist, Finland, Diptera, biodiversity, faunistics

Introduction

Three families are currently recognized in Lauxanoidea, two of which are present in Finland. The exception is the beetle flies (Celyphidae), which are restricted to the Oriental and Afrotropical Regions.

The silvery white flies of the family Chamaemyiidae are poorly studied in Finland. Reliable identification of most species is, at least for now, only possible by the examination of male genitalia. Unfortunately many species have not been adequately (re)described which has resulted in much confusion about the proper use of species names. It is likely that several additional chamaemyiid species will be found in Finland. Of the two subfamilies of chamaemyiids, Cremifaniinae is absent from Finland. Chamaemyiinae is split into two tribes, Chamaemyiini and Leucopini, although the monophyly of the former has not yet been demonstrated (Gaimari 2010).

The lauxaniids are better known both in Finland and worldwide. Additional species are still likely to be found in the country, especially among Homoneura and Sapromyza. Of the three subfamilies, the Eurychoromyiinae, a strictly Neotropical group (Gaimari and Silva 2010a), is absent from the Palaearctic. The other two subfamilies, Homoneurinae and Lauxaniinae, are both present in Finland The subfamily Lauxaniinae is probably paraphyletic as currently defined (Gaimari and Silva 2010b).

The Finnish species of these families were last listed by Hackman (1980). Kahanpää (2013) reviewed the changes in the Finnish lauxaniid fauna since 1980.

Number of species (Chamaemyiidae, Lauxaniidae):

World: 336 (S. Gaimari, pers. comm. March 18, 2014), 1895 species (Pape et al. 2011)

Europe: 107, 157 species (Fauna Europaea)

Finland: 27–28, 45 species

Faunistic knowledge level in Finland: poor, average

Notes

Several chamaemyiid species mentioned in this checklist have not been previously recorded from Finland. A paper detailing the new records is in preparation.

Chamaemyia herbarum (Robineau-Desvoidy, 1830). A poorly known species. The name has been widely used for various Chamaemyia species in the past. Coe (1943) and Collin (1966) applied this name (without seeing types) to a species which may be C. subjuncorum Tanasijtshuk, 1980 (sensu Beschovski, 1995). Czerny (1936) and Tanasijtshuk (1986) listed this species as a junior synonym of Chamaemyia juncorum (Fallén). Most Finnish specimens under this name are either unidentifiable females or belong to other species, most frequently C. aestiva Tanasijtshuk, 1970, but some specimens probably belonging to C. herbarum R.-D. sensu Coe have been found in Finland.

Minettia (?) styriaca (Strobl, 1892). This species, originally described in Sapromyza, has traditionally been placed in Minettia. Unfortunately Strobl’s description, which was based on a single female, is rather short and unillustrated. The holotype is lost according to Chvála (2008). The Finnish and Russian material in the Finnish Museum of Natural History (MZH) identified as Minettia styriaca (see Kahanpää 2013 for data and a photograph) matches Strobl’s description, but these specimens lack the postsutural supra-alar setae found in Minettia (and many other genera).
