Regarding secondary sex variation the greater
body size of females are not here offered attention.
The males, however, may have extra structures,
heavier spines, darker pigments or different
pigments.
Genetic (non-sex associated) continuous variation
is representated by gradually disappearance
of structures or pigment spots in adult specimens
of the same species, (for instance gradually
disappearance of two dorsally light spots in
N. bimaculatumJ. Allometric variation (nongenetic)
is found in R. triangularis.
Here the juveniles have a very great tuberculum
oculorum related to the body size. This
relation changes with growth.
Habitat variation is perhaps found in L. palpi­REFERENCEnalis.
All individuals in some populations are sometimes
covered with numerous, dark pigment
dots on the body.
One rare chromosome mutation was discovered
in a specimen of O. tridens. The whole tuberculum
oculorum was gone. The same was an
ocellus. Since so great parts of the phenotype are
changed, and since in theory a simple attribute
may be governed by several genes (polygenic),
and one gene may be pleiotrophic (Mayr, 1975),
it is possible that parts of a chromosome were
destroyed. Physiological attributes may also
have been changed. One could suggest that this
genotype will be selected against by the environment.
DATES AND AUTHOR NAMES OF TAXA
Comments to the author names and dates of
some taxa: Phalangiidae and Phalangiinae are
sometimes referred to as Simon, 1879 (Roewer,
1923. Sankey & Savory, 1974, Martens, 1978). I
have, however, adopted Latreille, 1802 as done
by Starega (976). Sankey & Savory (1974) refer
Opiliones to Sundevall, 1832. I have, however,
adopted Sundevall, 1833 as done by Roewer
(1923) and Starega (976).
Nemastomatidae is sometimes referred to as
Simon, 1879 (Sankey & Savory, 1974, Martens,
1978). I have, however, adopted Simon, 1872 as
done by Roewer (923) and Starega (1976).
Sankey & Savory (974) refer Leiobuninae to
Banks, 1895. I have, however, adopted Banks,
1893 as done by Roewer (923), Starega (976)
and Martens (978).
Martens (978) writes IIMitopus moria (Fabricius,
1799»>. This should be regarded as a misprint.
I have adopted «1779» as the correct date,
as done by Fabricius (1779), Sankey & Savory
(974) and Starega (976).
