Abstract

Hatchlings were obtained from eggs laid by Testudo hermanni hermanni GMELIN, which had hatched in captivity in 1965. To our knowledge this is the first report of a second generation breeding of Testudinidae under conditions in captivity. Two hybrid hatchlings between a male T. h. hermanni and female Testudo horsfieldii (GRAY) were also obtained.

Abstract. The egglaying (4 eggs) of a Testudo horsfieldii (1570g), which lives in a large outdoor enclosure since 1968, was observed. In a special breeding apparatus two hybrids hatched, the two other ones died in the shell. The parent's mating had not been observed. Fertile males of Testudo h. hermanni (7), Testudo horsfieldii (2) and Testudo graeca ibera (1) are living together in the enclosure with female tortoises. An analysis of the phenotype demonstrated the two hatchlings to be hybrids between T. horsfieldii and T. hermanni. The inauguration of a separate genus Agrionemys is critically discussed.

Zusammenfassung. Von einer beobachteten Eiablage (4 Eier) einer Testudo horsfieldii (1570g), die seit 1968 in einer grossen Freiland-Anlage lebt, schlüpften in einem speziellen Brutapparat zwei Bastarde, während 2 Embryonen abstarben. Die vorangegangene Paarung konnte nicht beobachtet werden. In der Anlage Ieben fertile ♂♂ von Testudo h. hermanni (7), Testudo horsfieldii (2) und Testudo graeca ibera (1) . Durch Merkmalsanalyse der Bas tarde konnte eine Kreuzung zwischen Testudo horsfieldii und Testudo h. hermanni nachgewiesen werden . Die Berechtigung einer eigenen Gattung Agrionemys fiir die Art h orsfieldii wird kritisch diskutiert.
