Parasites in Spanish populations of Psammodromus algirus (Algerian sand lizard, lagartija colilarga) and Psammodromus occidentalis (Western Sand Lizard, lagarto de arena occidental) (squamata, lacertidae, gallotiinae)

Psammodromus algirus from Madrid, Ávila, and Cádiz provinces, Spain, and P. occidentalis from Cádiz province were examined for the presence of external and internal parasites. Among those parasites represented were: Ixodes inopinatus (Arthropoda, Arachnida, Acari, Ixodidae); Haemaphysa-lis punctata (Arthropoda, Arachnida, Acari, Ixodidae); Skrjabinelazia cf. taurica (Nematoda, Secernentea, Ascaridida, Seuratidae); Spauligodon carbonelli (Nematoda: Secernentea, Oxyurida, Pharyngo-donidae); Parapharyngodon psammodromi (Nematoda, Secernentea, Oxyurida, Pharyngodoni-dae); Abbreviata abbreviata (Nematoda, Secernentea, Physalopteroidea, Physalopteridae); Meso-cestoides sp. (Platyhelminthes, Cestoda, Cyclophyllidea, Mesocestoididae); and Oochoristica cf. tuberculata (Platyhelminthes, Cestoda, Cyclophyllidea, Davaineidae). Details regarding localities from which host species were collected, number of parasites and sites of attachment, and estimates of prevalence and intensities of infection are presented. Nematode diversity, along with parasite prevalence, parasitaemia, and relationship to elevation are also discussed. A table of Psammodromus parasites in Spain is also included.
