title: New species and records of scale mites (Acari: Pterygosomatidae) from Arabian Agamid lizards (Squamata: Agamidae).
abstract: Two new species of pterygosomatid mites parasitizing lizards of the family Agamidae are described: Pterygosoma aqabensis sp. nov. from Pseudotrapelus aqabensis Melnikov et al. and Pterygosoma dhofarensis sp.nov. from Pseudotrapelus dhofarensis Melnikov and Pierson both from Arabian Peninsula. Pterygosoma aqabensis sp. nov. is most closely related to P. dhofarensis sp. nov. but differs by the presence of subcapitular setae n, setae vFI and vGIV, 14-21 pairs of the antero-dorsal setae, 4 pairs of dorso-median setae dm, 5-6 pairs of the postero-lateral setae and 7 pairs of pseudoanal setae ps, palp setae dG and dF are subequal in the length and setae vm3 are slightly serrated. P. dhofarensis sp. nov. is similar to P. sinaita Jack, 1961 but in the new species setae dm1 are serrated and setae dm2 are filiform, 3 or 4 pairs of the medio-lateral setae and 2 pairs of peripheral setae are present, setae dGI are absent. A redescription of Pterygosoma adramitana Jack, 1961 from the type host Acanthocercus adramitanus (Anderson) (Agamidae) is given.
