DISCUSSION
DISTRIBUTION
In Norway 14 species of Opiliones are known
when O. parietinus is excluded from the list. O. ECOLOGY
hanseni and N. gothica are recorded for the fIrst
time. In addition L. rupestre is found with certainty
in Norway. Strand (I 900) described L. norvegicum
from Oslo. This species seems to be a
junior synonym for L. rupestre, as noted by
Martens (I 969).
Western distributed species seem to be N. bi­formmaculatum
and M. diadema, while N. lugubre
appears to be eastern distributed. O. hanseni, P.
agrestis, N. gothica, L. rupestre, L. rotundum apparently
are coastal distributed species. dum.
Widely distributed species seem to be P. opilio.
R. triangularis, L. palpinalis, O. tridens, L.
ephippiatus, M. morio.
The following species appear the ones most
abundant in N9rway. O. tridens, L. palpinalis,
N. bimaculatum, P. agrestis, M. morio, L. ephippiatus,
N. lugubre (a species taken in many localities
and great number).
Six species are reported north of Trondheim:
N. bimaculatum, N. lugubre, R. triangularis, O.
tridens. L. ephippiatus, M. morio.
Only M. moria is reported from Troms and
Finnmark. Maps are found in Appendix lI.
The previously existing distribution maps
(Gruber & Martens, 1968, Starega, 1976, Martens,
1978), showing the distribution of N. bimaclllatum
and N. lugubre in Norway, should be
considered as incorrect.
Martens (J 978) writes about O. parietinus:
«.... fUr Norwegen und Schweden nicht gennant».
The species, however, is published from
Sweden by Tullgren (I906) and (rom Norway
by Strand (I 900). From Norway, however, it is
perhaps incorrectly reported.
Martens (I 978) does not mention R. triangularis
from Iceland and The Faroes although it is
reported by Henriksen (I 938).
Martens (I978) writes about L. palpinalis:
«Keine Nennungen fUr Finnland und Norwegem>.
L. palpinalis, however, is known from
Norway in great number and is published by
Kauri (I 977).
Martens (I 978) does mention L. ephippiatus
from Iceland and The Faroes although it is reported
by Henriksen (I938) and later by Kauri
(I 980).
The occurrence of Nelima silvatica (Simon,
1879) in Denmark and England as written by
(Brown & Sankey, 1949, Meinertz, 1962, 1964,
Sankey & Savory, 1974) is incorrect. It seems to
be Nelima gothica as noted by Martens (I969,
1978).
Adults of N. bimaculatum were found throughout
the year. Table 1. Meinertz (I 964) reports
the same to be true for N. lugubre. Adults of other
species seem to be present 2- 5 months a
year. None adult R. triangularis was taken. Meinertz
(I 964) reports it, however, to be a summer
One species is a spring form: M. diadema.
Five species are summer forms: N. lugubre, P.
opilio, R. triangularis, L. ephippiatus, L. rotun­
Eight species are autumn forms: N. bimaculatum,
O. tridens, M. morio, L. rupestre, N. gothica
(early in autumn) and L. palpinalis, O. hanseni,
P. agrestis (late in autumn).
Nearly the same occurrence is reported from
Denmark by Meinertz (I 964).
Most of the species prefer deciduous wood.
Deviations here seem to be M. diadema, preferring
coniferous wood (based on few specimens).
L. palpinalis seems to prefer heather. O. hanseni
is mostly taken in garden/parks. P. opilio and P.
agrestis seem to prefer both garden/parks as
well as grazing land.
MORPHOLOGICAL VARIAnON
Nongenetic age variation and genetic sex variation
(secondary differences) were frequently discovered,
Table 2.
Age variation may affect important identillcation
and classifIcation attributes and characters,
phenotypically manifested in absence of structures
in juveniles. There are also absence of pigments
and pigment patterns in juveniles.
