Medium-sized (5.0-10.0
mm), usually dark-coloured Nematocera with elongated body and
legs. Eyes usually holoptic in male, separated in female; three
ocelli; antenna relatively short, tapering, scape and pedicel
short, flagellum with 14 segments. Wing moderately large, with a
characteristic pattern of dark markings, C ending at or slightly
beyond tip of R, Sc ending in C at about middle of the wing. The
larvae are found in various decaying organic materials such as
the stems and roots of umbelliferous plants (Hancock
1989). The common species Sylvicola cinctus
(Fabricius, 1787) has also been reared from fungi (Ševčík
2001). The adults occur mainly in forest habitats, but
frequently also in gardens or on windows in houses; they feed on
nectar and other liquids (Krivosheina
1997).
Altogether nine species
are known to occur in Europe (de
Jong 2007); six of them are listed in the present checklist
– five from the Czech Republic (five
from Bohemia, five from Moravia), and six from Slovakia. Since
the PCV2 (Kovář
1997), the number of species in the Czech Republic has
remained the same (one species added for Bohemia, one for
Moravia) while two species have been added to the fauna of
Slovakia (Ševčík
2004,
2005). The species composition of the anisopodid fauna in
both the Czech Republic and Slovakia is relatively well known.
The basic characteristics
of the family were recently given by Krivosheina (1997).
The identification of the European species is based mainly on
the structure of the male or female terminalia and is possible
using the keys and figures by Haenni (1997),
Krivosheina and Menzel (1998),
and Søli (1992).
The nomenclature used in the present checklist follows that in
the Fauna Europaea (de
Jong 2007).
