■ Abstract A critical reexamination of turtle relationships continues to support a sister-group relationship of turtles with a clade of marine reptiles, Sauropterygia, within crown-group Diapsida (Sauria). The high Homoplasy Index raises concerns about the phylogenetic information content of various morphological characters in broadscale phylogenetic analyses. Such analyses may also suffer from...

Caudal autotomy, the ability to shed the tail, is common in lizards as a response to attempted predation. Since Arnold’s substantial review of caudal autotomy as a defence in reptiles 20 years ago, our understanding of the costs associated with tail loss has increased dramatically. In this paper, we review the incidence of caudal autotomy among lizards (Reptilia Sauria) with particular referenc...

Two new species of pterygosomatid mites Pterygosoma garissi sp. nov. and P. fragilis sp. nov. (Acari: Pterygosomatidae) are described from the agamid lizard Agama agama (Sauria: Agamidae) from Kenya. P. garissi sp. nov. is similar to P. annectans Jack, 1962 but in the new species the peripheral setae are slightly expanded apically, 3 pairs of setae are situated on the coxal fields I and and 2 p...
