Medium-sized (4.0-8.0 mm), dark coloured
Nematocera with elongated body and legs. Eyes separated, but almost
touching at vertex; three ocelli; antenna relatively short,
tapering, scape and pedicel short, flagellum with 14 segments. Wing
moderately large, without dark markings, C ending beyond tip of R,
anal vein strong and reaching wing margin, d-cell absent. The larvae
are saprophagous and are found in various decaying and fermenting
organic materials such as sap runs, or under the bark of trees (Hancock
et al. 1996,
Krivosheina 1997). The adults are very rare, occurring from May
to June, mainly in forest habitats.
Altogether three species are known to occur in Europe
(Chandler
2007); all of them are listed in the present checklist
–
three from
the Czech Republic (three from Bohemia, three from Moravia), and two from
Slovakia. Since the PCV2 (Martinovský
1997), one species has been added to the fauna of the Czech
Republic (also one for Moravia) and two species to the fauna of
Slovakia (Ševčík
1999,
2004,
2005).
One species new to Bohemia was recently added by Ševčík et al. (2009).
The species composition of the mycetobiid fauna in both
the Czech Republic and Slovakia is relatively well known, although
at least one additional species is expected.
The basic characteristics of the family were
recently given by Krivosheina (1997).
The systematic position of the family is still not fully clarified
and some authors tend to treat it as a subfamily of the Anisopodidae
(Michelsen
1999). The identification of the European species is based
mainly on the complex structure of the male or female terminalia and
is possible using the keys and figures by Hancock et al. (1996)
and Mamaev (1968).
The nomenclature used in the present checklist follows that in the
Fauna Europaea (Chandler
2007).
