1.Introduction<br />
This report is an update of the annual report of the <strong>Studbook</strong> Breeding<br />
Programme Pyxis arachnoides published in 2010.The <strong>programme</strong> aims to<br />
form a genetically healthy, reproducing captive population, to study and<br />
to gather and distribute as much information about Pyxis arachnoides as<br />
possible. In order to keep the studbook manageable (in terms of number<br />
of tortoises and contacts between participants and coordinator), it has<br />
been decided that the studbook will operate exclusively in Europe.<br />
Contacts have been made with Michael Ogle, author of the “North<br />
American Regional <strong>Studbook</strong>” for Pyxis arachnoides (4 th edition).<br />
However this North American studbook is not intended for distribution.<br />
Although Pyxis a. arachnoides appears to be present in Europe in<br />
sufficiently large numbers for a viable studbook, the situation for the<br />
other two subspecies, brygooi and oblonga, is somewhat different.<br />
Although both subspecies are bred in captivity, the total number of living<br />
tortoises in the studbook is to low to form a genetical healthy captive<br />
population. In the (near) future it might be advisable to establish closer<br />
contacts outside Europe to import tortoises of both subspecies (brygooi<br />
and oblonga).<br />
2. Current living studbook population<br />
Table I: Current living studbook population Pyxis arachnoides per<br />
location as registered in the studbook. MULT1 is sire 26 or 27
a) Pyxis arachnoides arachnoides<br />
There are currently 92 animals (40.23.29) at 14 locations. Four animals,<br />
kept at two locations, are considered as “Lost to follow up” and are listed<br />
in a separate list (8.Lost to follow up at page 13)<br />

3. Locations<br />
At the moment there are 24 locations in the studbook that keep and/or<br />
breed Pyxis arachnoides. 14 Locations keep Pyxis a. arachnoides (16<br />
locations excluding 2 location as “lost to follow up”), 7 locations keep<br />
Pyxis a. brygooi and 2 locations keep Pyxis a. oblonga (3 locations<br />
excluding one location as “lost to follow up”).<br />
Of these locations there are a few that are not responding to contacts<br />
made by the studbookcoordinator : A19, Wass BR C (all of these<br />
locations keep (?) Pyxis a. arachnoides), A17 (this locations keeps (?)<br />
Pyxis a. oblonga). Especially the last locations is of more importance to<br />
the studbook than the other locations, due to the fact that there are very<br />
few Pyxis a. oblonga in the studbook. All of these animals are considered<br />
“lost to follow up”. However, it is not the first time that animals,<br />
considered “lost to follow up”, at some time pop back up in the studbook,<br />
registered at another (new) location. This situation is far from desired but<br />
better this than a complete loss.<br />
“Lost to follow” up animals will be kept on a separate list (see chapter 8).<br />
A few locations stopped keeping Pyxis arachnoides (London RP, A11,<br />
A39). Some of these tortoises died, others were transferred to other<br />
locations, or are in the progress of being transferred to other locations. A<br />
few animals were transferred outside the studbook, which is regrettable.<br />
4.Births
This chapter is the highlight of the studbook. The more, the merrier.<br />
In 2010, 12 animals were born at 5 locations. 3 Pyxis a. a. at 2 locations,<br />
2 Pyxis a. brygooi at one location and 7 Pyxis a. oblonga at 2 locations.<br />
Especially the new born Pyxis a. oblonga (6 at location A14 and 1 at<br />
location A40) is extremely good news, since there were only 13 Pyxis a.<br />
oblonga in the studbook (excluding the 3 animals of location A17). This<br />
means a population growth of almost 50% in one year. Congratulations to<br />
the breeders, to all breeders.<br />
5.Deaths<br />
Three animals died in 2010, 2 Pyxis a. arachnoides(2.0.0) and one Pyxis<br />
a. brygooi (0.0.1)<br />

brygooi (0.0.9) and 2 Pyxis arachnoides oblonga (1.0.1).<br />
6.Imports<br />
No import of any Pyxis arachnoides took place in 2010 for the studbook.<br />
7.Transfers<br />
As mentioned before, there were several transfers of Pyxis arachnoides in<br />
2010. Some transfers are still in the ongoing phase. Location A11 stopped<br />
keeping Pyxis arachnoides. All of these animals were transferred to<br />
location A08, from where a part will be transferred to other locations (pe<br />
locations A13, A10).<br />
Also location A41 decided, at one point, to stop keeping Pyxis<br />
arachnoides, brygooi in this case, but was convinced by the<br />
studbookcoordinator to keep, at least a part, of the animals. Since this<br />
location was and still is important for the studbook, due to the fact that<br />
this is a location at which regular <strong>breeding</strong> of Pyxis arachnoides brygooi<br />
takes place. Most of the animals were transferred to location A10.<br />

9.Situation in the wild<br />
Overall, the situation for Pyxis arachnoides in the wild is very<br />
worrisome. Populations are rapidly declining.<br />

10.Plans for 2011<br />
-An article, stating the existence and the goals of the studbook, will be<br />
written and send to several tortoise magazines.<br />
-A further exchanging of tortoises between locations in the studbook.<br />
-A questionnaire was send to numerous locations of the studbook, a<br />
report stating the findings will be made up and listed in the appendix of<br />
next years studbookreport or in a separate report.<br />
11.Identification of subspecies<br />
Since there, sometimes, is confusion about to which subspecies an animal<br />
belongs to, I will publish some photo’s of Pyxis a. arachnoides and Pyxis<br />
arachnoides brygooi. The subspecies Pyxis arachnoides oblonga is easy<br />
to distinguish from the other two subspecies because it has black spots on<br />
its plastron. The plastron from arachnoides and brygooi are without black<br />
spots. The difference between the last two subspecies lies in the fact that<br />
for arachnoides the anterior part of the plastron has a hinge which allows<br />
the tortoise to move/ partly close the front of its plastron. The plastron of<br />
brygooi is rigid. Whether or not the plastron can be moved, is somewhat<br />
difficult to see in a photo. Therefore it is always best, if possible, to look<br />
at the tortoise itself, to feel whether the plastron can be moved or not.
Male Pyxis arachnoides arachnoides (Photo by Frank van Loon)<br />
Female Pyxis arachnoides brygooi (Photo by Frank van Loon)
The first picture shows a Pyxis arachnoides arachnoides, here we can see<br />
the moveable hindge just left of where the front limbs end. On the second<br />
picture (below) we see a Pyxis arachnoides brygooi. On these two<br />
pictures, one can easily see the difference between the two subspecies.<br />
12.Identification of gender<br />
Another “problem” is the difference between male and female. At young<br />
age, this is not easy to determine. There are tortoise species where the<br />
difference between the sexes can be said (fairly accurate) at an early stage<br />
(for instance with Malacochersus tornieri, Homopus s. signatus, pers.<br />
Obs.). With Pyxis arachnoides this is not the case (in my opinion). The<br />
difference of the sexes in this species, as in most tortoise species, is can<br />
be seen in the tailsection. Males have a large, long tail, whereas females<br />
have a (much) smaller tail. Below a few pictures of adult/subadult<br />
animals of both sexes.<br />
