 18-20  15-17 |
-
Scorpions of large
size, females are up to 9 cm,
and the males over 13 cm. Hadogenes
bicolor is the sister species
of
H. longimanus. Thes
two species are both characterized
by a pronounced lobe, distal
to the notch in the fixed finger
of the pedipalp chela of adult
male and female, and a relatively
short metasoma in the adult female.
Hadogenes
bicolor can be separated from
H. longimanus by the presence
of two, rather than 5-8, trichobothria
on the internal surface of the
pedipalp chela. Color: pale
chelicerae, legs and telson contrasting
markedly with darker carapace,
pedipalps, tergites and metasomal
segments I-V. Sternites also
paler than tergites and metasomal
segments.

Hadogenes
longimanus is the sister
species of H.
bicolor. These two
species are both caracterized by
a pronounced lobe, distal to the
notch in the fixed finger of the
pedipalp chela of adult male and
female, and the relatively short
metasoma in the adult male, compared
with other Hadogenes.
Hadogenes
longimanus can be distinguished
from H. bicolor, and from H.
newlandsi,
by the presence of 5-8 trichobotria
on the internal surface of the
pedipalp chela. Color: legs and
tergites I-VI slightly paler, but
not contrasting markedly with pedipalps,
carapace, tergite VII and metasoma.
Telson not distinctly paler than
metasomal segments I-V. Sternites
distinctly paler than tergites
and metasoma. The females are darker
than the males. Size: the females
are up to 9 cm and male can reach
14 cm.

Hadogenes
newlandsi is most closely
related to the group comprising
H. bicolor and H.
longimanus. In
all three species, the distal width
of metasomal segment I is greater
than the height. Hadogenes
newlandsi can
be distinguished from the latter
species by the absence of a pronounced
lobe, distal to the notch in the
fixed finger of the pedipalp chela
of adult male and female, nad by
the longer metasoma of the adult
male. This species is further characterized
by the presence, in adult male, of dense granulation
on the telson and lateral surface
of metasomal segment V. Size :
female are up to 7,5 cm, and male
over 15 cm. Color: pale legs contrasting
markedly with darker pedipalps,
carapce, tergites and metasoma.
Telson not distinctly paler than
metasomal segments I-V. Sternites
distinctly paler than tergites
and metasoma.

Color variable according to
the origin but in general the body,
the pedipalps and the metasoma
are dark brown to brown tobacco,
with the telson yellow straw at
the old specimens. The legs are
yellow orange, rather clear.

Scorpion
of color brownish, more clearly
between each plate of the mesosoma.
Metasoma, legs and pedipalps more
clearly (yellowish orange) with
the fingers black. Aculeus a little
clearer than the legs. Some specimens
are however darker.

Note
: For
these species the sexual dimorphism being
very obvious (metasoma much longer in the
male), the number of teeth of comb is really
additional
The
Breeding
Temperature:
This
kind of scorpion easily
tolerates temperatures
of more than 35°C,
however, in breeding
30°C will be enough,
with, for the night,
a fall of at least 10°C
if possible. For the
species who's live in
South Africa, a winter
diapause is welcome.
At this time, a temperature
of 15/20°C would
be then preferable. To
grow correctly, the young Hadogenes one
need for temperatures
often nearer to the 35°C
because at a temperature
of 22/24°C no moult
is carried out.
Food:
The
crickets will be the
base of the breeding
supply. However, adults,
these species will
eat without problem
of the cockroaches,
the locusts, the lizards,
the myriapodes and
even of the small rodents.
It also appears that
in the event of food
shortage, in their
country of origin,
some of these scorpions
would eat snails.
For the babies, the
micro-crickets
will make the deal.
Hadogenes are not big
eaters, he is frequently
able that the prey
is forsaken during
one week, to see more,
before it does not
disappear. Also you
do not worry too much.
These scorpions have
a great longevity,
but also a very slow
growth.
Terrarium:
Hadogenes are
scorpions living in
rocky area.
One finds them in the
cracks, from where
forms to them so special,
which did not plait
in all the world. One
will thus need a terrarium
of big size, and solid,
with much of stones
punts (slate kind,
or others). These stones
will be they, posed
on a substrate made
up of argillaceous
ground or dry peat,
but especially not
on sand. For this kind
of scorpion, the terrariums
quickly become very
heavy, therefore made
attention in the event
of displacement. Hygroscopy
30-50%, rather dry
with nevertheless a
feeding trough at disposal.
In their country of
origin, it only falls
very little from water
during the year. One
can however vaporize
the stones and the
walls of terrarium
in order to water the specimen
occasionally. However for the
alive species plus meadows
of equator (Tanzania,
RD Congo etc...) needs
much more moisture.
One will more often
vaporize, and one will
keep the wetter substrate.
It is possible to make
cohabit several Hadogenes together, this species
is regarded as rather
sociable and calms.
However one should
not mix between various
species of Hadogenes and
food must be in quantity sufficient
for all the scorpions.
Sociability:
Hadogenes are
for the rather sociable
majority of the scorpions.
One can keep a couple
without problem. One
will only take care
to isolate the male
before a birth. The
stress because of the
presence of this one,
could like reaction
the setting with have
died of the pullus
by the female. The
size of these scorpions
makes that if you want
to put several couples
together, you will
need a very large terrarium.
Indeed, the competitions
male/male
and female/female
generates fights,
often invalidating
to see mortals for
weakest. For better
a growth and to avoid
any canibalism, the
youngs will be
isolated, put out of
pot individually.
Note:
Hadogenes are
not so inoffensive.
Admittedly the thickness
of the metasoma and
the length of the aculeus
show that the puncture
is not what it is necessary
to fear more, but not
to never leave your
fingers carry grips
of these scorpions.
The power is such as
it can cut you until the
bone. Attention thus... |
