Newt-Registry of the genus Cynops
(AG Urodela / Work Group for Tailed Amphibians)
Although the AG Urodela is
associated with the DGHT (German Society for Herpetology and Reptile/Amphibian
Husbandry) a lot of enthusiasts from all over the world and especially Europe
are members and participate in the activities of this Work Group. Therefore,
also the newt registry for the genus Cynops
should be regarded as an international and especially Pan-European endeavour.
newt-registry for Cynops aims at the
The conservation of rare and endangered species by captive breeding.
The coordinated exchange of animals, respectively their offspring between
registry members (studbook) and thus the reduction of collection of animals in
their natural habitats and imports.
The issue- and species-related counselling of beginners as well as
advancers by the registry tutors.
Engrossing of knowledge on species biology through captive
Provision of captive bred animals for potential restoration projects.
The compilation of species-specific literature.
The compilation of a picture
archive for this genus.
genus Cynops comprises seven
currently recognized species. The animals belonging to Cynops
are small to medium sized newts, which spend significant periods of their
life-cycle in the water.
species - C. pyrrhogaster and C.
ensicauda - occur on the Japanese islands whereas five – C. orientalis, C. cyanurus,
C. wolterstorffi, C.
orphicus and C. chenggongensis – can be found on the Chinese mainland.
of this genus are commonly known as „Firebellied Newts“ and have been
popular among enthusiasts for decades. In the past, C.
pyrrhogaster, the Japanese Firebellied Newt, used to be the only
species that was imported in Europe and North America. Because of legal
restrictions, this species has been replaced by the Chinese Dwarf- or
Firebellied Newt - C. orientalis
in recent years.
there are two more Cynops species kept by European enthusiasts. C. ensicauda the Sword-Tailed Newt from the Southern Japanese
Riu-Kiu archipelago and the Kweichow-Firebellied Newt - C. cyanurus, ocurring in the highlands of the Chinese province of
situation within the genus Cynops
in Europe differs significantly for particular species and thus different
species-specific focal points are adressed in the registry work.
is the only species, which is still being imported in masses with the
animals usually being in a terrible condition. There is sufficient captive
breeding in Europe, which renders further imports of wildcaught animals
unnecessary. First objective of the registry must therefore be the
dissemination of information on these facts and to provide an alternative
to imports by supplying captive bred offspring, which is usually
longer-lived and healthier.

The situation for the
two subspecies of Cynops
ensicauda is quite different. Whereas C.e. popei is bred regularly, only few reproductive groups of C.e.ensicauda
exist in Europe. The main goal for this subspecies must therefore be the
establishment of additional breeding groups. Since either of the
subspecies are no longer exported from Japan, captive breeding attains an
even greater importance nowadays.

situation for Cynops
pyrrhogaster seems to be rather complex. Years ago, this
species was imported in large numbers, but nowadays it has become quite
rare in captivity. The systematics of the pyrrhogaster-complex are still
uncertain and at least five local forms have been described in literature
with the different animals presumably having the status of subspecies.
form most commonly bred in captivity is sasayamae
and some few groups of the Hiroshima-form exist. The other forms are
encountered only rarely and the establishment of additional breeding
groups is planned. Because of the high variabilty in appearance of this
species, the assignment of individuals to specific forms respectively
populations proves to be quite difficult.

Cynops cyanurus is bred occasionally in European
aquariums. The two subspecies C.c.
cyanurus and C.c. yunnanensis
have been described. The differentiation of these subspecies still poses a
problem and thus the groups in the registry cannot be assigned to either
one. A problem still to be solved.

orphicus does not occur in private terrariums.
Cynops chenggongensis most probably is and has not been
kept in captivity anywhere.
For these two rare species mentioned above, the
establishment of stable breeding groups in captivity could help to avoid
the risk of complete extinction caused by the depletion of natural
is presumably extinct already. An excursion to the natural habitat for the
confirmation would be very much desirable. If remnant populations or
animals could be ascertained, conservation measures like the establishment
of nature reserves had to be put into effect. Experienced breeders could
also engage in a breeding program for restoration purposes of this species.
keeping one or more Cynops
species is invited to participate in the registry.
participants are informed about the status of the registry, appropriate
literature, breeding success and everything else being of interest for the
keepers of Cynops newts; the
exchange of animals as well as information between participants is
supported. Registry members have access to the registry’s bibliography
as well as the picture archive, the latter being still under construction.
Everybody is invited to make suggestions concerning the registry.
