Minute to small (1.0-2.5 mm), dark flies characterised by only a
humeral break on C, complete Sc, orbital setae reclinate to
exlinate (never inclinate), divergent postvertical setae, and
absence of true vibrissae. Tibiae without dorsal preapical
setae. Male postabdomen almost symmetrical, with 6th tergum
absent and 6th sternum joined to dorsal pregenital sclerite
(being almost symmetrical and composed of the fused 7th and 8th
sternum) on both sides. Epandrium with distinct ventral lobe in
front of free gonostylus. Female postabdomen telescopic,
retractible, with reduced sclerites and long, slender cerci.
Adults occur on various decaying substrates (fungi, carrion,
dung, even decaying grass), usually in woodland habitats. The
saprophagous larvae of Acartophthalmus bicolor Oldenberg,
1910 were found by Ozerov (1987)
in carrion; however, the other species may also develop in other
kinds of rotten organic media (Máca
& Roháček 1983,
Papp & Ozerov 1998).
Only
three species in one genus (Acartophthalmus Czerny, 1902)
are known in Europe (Ozerov
2007); all are also listed in the
present checklist: three in the Czech Republic (three in
Bohemia, two in Moravia), and three in Slovakia. Since the ECV1,
one species has been added to the fauna of the Czech Republic
(Bohemia only) by Roháček (2007).
The family was treated in detail by Papp and Ozerov (1998);
all known species can be identified by means of Ozerov (1986).
The nomenclature used here follows that in the Fauna Europaea (Ozerov
2007).
