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...

Many species have elaborate and complex coloration and patterning, which often differ between the sexes. Sexual selection may increase the size or intensity of color patches (elaboration) in one sex or drive the evolution of novel signal elements (innovation). The latter potentially increases color pattern complexity. Color pattern complexity may also be influenced by ecological factors related...

A new species of agamid lizard, of the genus Calotes, is described based on morphological evidence. This species is restricted to the Knuckles massif (>900 m elevation) of Sri Lanka. The genus Calotes consists of seven species in Sri Lanka, five of which appear to form an endemic radiation. The new species most closely resembles C. liocephalus Günther, 1872 which has an isolated population i...

Mabuya vitatta (Olivier) (Scincidae) and Agama stellio (L.) (Agamidae) were infected with Hemolivia mariae Smallridge et Paperna, 1997 by ingestion of tick viscera from Amblyomma limbatum Neumann, fed as nymphs on naturally infected Australian sleepy lizards, Tiliqua rugosa Gray. The unnatural infection apparently interfered with the developmental schedule of the parasites. Transmission electro...

The characteristics of the hemipenis Scincidae and Agamidae New Guinea are veryrarely studied, although they very easy to do. Morphological andhemipenis size between these two families different. Some have a cylindrical that is not lobed lobed, some even variety structures withdistinctive ornaments. Tail length can affect hemipenis. This study aims describe Guinea. species Lamprolepis smaragdin...
