The Australian Tawny Dragon lizard (Ctenophorus decresii), as currently recognized, comprises two genetically divergent lineages, northern and southern, that differ notably in male coloration. A narrow contact zone exists between the lineages with asymmetric limited hybridization, indicating incompatibility highlighting need for further taxonomic assessment. Here, we evaluate morphological vari...

The rock agama, Laudakia caucasia Eichwald (Agamidae) is host to Plasmodium caucasica sp. n. and Saurocytozoon agamidorum sp. n. in western Pakistan. Plasmodium caucasica is characterized by very large meronts, 11-21 by 8-17 microm that produce 32-67 merozoites, which nearly fill the host erythrocyte, and smaller, ovoid to elongate gametocytes, 6-14 by 2.5-6 microm, with length by width (LW) 21...

The exact homologies of tetrapod jaw muscles remain unresolved, and this provides a barrier for phylogenetic analysis and tracing character evolution. Here, lepidosaur jaw muscles are surveyed using direct examination of species from 23 families and published descriptions of species from 10 families. A revised nomenclature is applied according to proposed homologies with Latimeria. Among lepido...
