damp forests, which may explain its low numbers
here. It was caught in Barbers 3 & 4.
Cylindroiulus punctatus is the most common subcorticolous
julid in the Atlantic zone. It was quite well
represented and trapped by all methods.
Tachypodoiulus niger was apparently by far the
most abundant species in the Schnellert. This is
significant as it is associated with better soils than
J. scandinavius and reaches its maximum numbers
in forests on limestone. It is essentially a forest
species. The good drainage of the soil might be
implicated. It is a rather tolerant Western European
species which is however lacking from many of the
forests in the Ardennes which may be too wet, cold
or acidic in nature, and where J. scandinavius and/
or L. simplex glacialis may be found.
The second most abundantly recorded species
was Craspedosoma rawlinsi. This is a Central
European litter dweller which reaches Scandinavia
and the British Isles. It is very common in
this part of Europe. It is active during the winter
and favours moist habitats with coarse-grained
leached soil and thick litter. It is a fairly tolerant
“generalist” species, very common in montane

woodland, one of the commonest species of forests
in the Ardennes. The subspecies here present is
C. rawlinsi alemannicum, recorded by Remy and
Hoffmann as C. alemannicum.
Another species which is very common in damp
forests in Central Europe is Chordeuma sylvestre. It is
also a generalist, even more so than Craspedosoma.
Numbers were low in the Schnellert, maybe because
of the suitability of the habitat for Craspedosoma. It
was not confined to one part of the forest.
Only one adult specimen of Melogona gallicum was
recorded, a species which is widespread and often
abundant in Atlantic forests of most types. It was
captured by sieving in February, 1999, at station 1A.
Orthochordeumella pallida is another chordeumid
which has a disjunct distribution in the Alps and
western part of Central Europe. It is associated with
cool deciduous forests with good litter cover and
associated with soils that have a high silt content.
In Belgium we additionally found an association
with medium sand and low clay content. The
two adults were obtained by sieving in areas 1
and 2. It may also be involved in competion with
Chordeuma and Craspedoma species.
