The members of Gyrophaena, Aleocharinae
(Coleoptera: Staphylinidae), are obligate inhabitants
of fresh mushrooms as larvae and
adults. They live on both polypore and gilled
mushrooms. Adults appear on mushrooms
soon after the gills are exposed or the hymenium
area becomes active, and both larvae
and adults occupy more mature mushrooms.
Gyrophaenines inhabit only fresh mushrooms
and are usually among the first insects to appear
on them (Ashe 1984). Until recently, the
genus Gyrophaena Mannerheim, 1830 was
represented by 10 species in Turkey (Anlaş
2009). Following Assing’s recent studies
(2009 and 2011), two new species and three
new records were added to this number. With
the newly described species, the total number
of Gyrophaena species found in Turkey has
been raised to 16.
