Myrmechixenus subterraneus
CHEVROLAT
,
1835
R e m a r k s: The species is known from Europe and European
Russia
. For
Latvia
it was recorded by
ULANOWSKI (1884)
and
MÜTHEL (1889)
.
As a result of our study, in total we registered 35 species of 8 families from nests of
Formica
and
Lasius
:
Carabidae LATREILLE, 1802
,
Histeridae GYLLENHAL, 1808
,
Ptiliidae ERICHSON, 1845
,
Staphylinidae LATREILLE, 1802
,
Scirtidae FLEMING, 1821
,
Latridiidae Erichson, 1842
,
Monotomidae LAPORTE DE CASTELNAU, 1840
and
Tenebrionidae LATREILLE, 1802
. The dominant family in nests of ants is
Staphylinidae
, which constitutes 74% of the total number of registered species. For the genus
Formica
we observed 31 species of beetles, for
Lasius
- 7 species, four species of which have been observed only for these ants, and three species also met with
Formica
. Dominant species in nests of
Formica
are
Acrotrichis montandonii
(AL.)
,
Amidobia talpa
(HEER)
,
Lyprocorrhe anceps
(ER.)
,
Thiasophila angulata
(ER.)
,
Leptacinus formicetorum
MAERK.
and
Myrmechixenus subterraneus
CHEV.
; in nests of
Lasius
-
Pella limbata
(PAYK.)
. Almost a third of all observed species from the nests of
Formica
were represented by only
one specimen
, from nests of
Lasius
– three species.
The studied fauna of myrmecophilous beetles included five zoogeographical elements with a predominance of Transpalaearctic, European and European-Siberian species: Transpalaearcrtic – 14 species (40%), European-Siberian – 10 species (28.5%), European – 8 species (22.9 %) and Cosmopolites – 3 species (8.5%).
Based on the classification of groups of myrmecophilous invertebrates of
Wheeler (1910)
, all myrmecophilous
Coleoptera
species which were observed by us in nests of ants can be are divided into the following categories: synechthrans (
Quedius brevis
); neutral synoeketes (
Myrmetes paykulli
MARS.
,
Acrotrichis montandoni
(AL.)
,
Amidobia talpa
(HEER)
,
Lyprocorrhe anceps
(Er.)
,
Notothecta flavipes
(GRAV.)
,
Oxypoda formiceticola
MAERK.
,
Thiasophila angulata
(ER.)
,
Stenus aterrimus
(ER.)
,
Leptacinus formicetorum
MAERK.
,
Corticaria longicollis
(ZETT.)
,
Monotoma
spp.
,
Palorus depressus
(F.),
Myrmechixenus subterraneus
CHEV.
), symphiloid synoeketes (
Dinarda maerkelii
KSW.
,
Pella limbata
(PAYK.))
and symphiles (
Scydmaenus hellwigii
,
Euplectus
spp.
). Other species which were registered by us occur in ant-hills only accidentaly, and their occurance depends on the habitat where the nests are located, and the time of year (in autumn, many species use nests of ants for overwintering).
