Testudinidae brygooi The Madagascar spider tortoise (Pyxis arachnoides spp.) is faced with the threat of habitat destruction as well as the international pet trade. Habitat requirements and population structure of this species are largely unknown. Detailed studies have so far concentrated on the subspecies Pyxis arachnoides arachnoides. The present study surveyed a population of the western subspecies Pyxis arachnoides brygooi during the wet season from February to April 2008. The survey was carried out in the forest of Ifaty - Mangily, 20 km north of Toliara, and supported by a local tortoise centre, the Village des Tortues. Population densities were estimated from transect counts and plot surveys; they range from 0.33 to 1.72 animals per hectare. Both sexes were evenly represented in the field during the research period. Three individuals of the subspecies Pyxis arachnoides arachnoides were detected during this field survey. Their presence might be due to a transitional zone of both subspecies in the area of research.
