Three species of Skrjabinelazia Sypliaxov, 1930 (Nematoda: Seuratidae) parasitic in Gekkonidae and Lacertidae from South Africa, Europe and Australia.
Skrjabinelazia Sypliaxov, 1930 comprises 10 species distinguished by several characters typical of the genus including, among the most important, the presence/absence of spicules, cuticle ornamentation and vesicles, head-shape, the presence/absence of a leaflet crown in the buccal cavity, female tail-shape and male cone-shape. The three samples studied are new species: S. boomkeri n. sp., a parasite of Pachydactylus turneri, Gekkonidae, from South Africa (Klaserie Reserve); S. vozae n. sp., a parasite of Lacerta vivipara, Lacertidae, from France (Cévennes), which is close to two lacertid parasites, S. taurica Sypliaxov, 1930 and L. hoffmanni Li, 1934, respectively from the Crimea and North China (Peking); and S. mawsangelae n. sp. (male unknown), a parasite of Christinus marmoratus, Gekkonidae, from Australia (Pearson Island), which is, surprisingly, distinct from Skrjabinelazia sp. of Angel & Mawson (1968) from the same host in another region (North of Adelaide) of South Australia. Two main groups are distinguished in Skrjabinelazia: the species with spicules which are parasitic in the Lacertidae, and the species with a gubernaculum only which are parasitic in the Gekkonidae. The unique species described from the Iguanidae, S. intermedia (Freitas, 1940) from Brazil (Para), also without spicules, seems to be derived from gekkonid parasites, as it also has an evolved oesophagus with a glandular region, unlike the simple oesophagus seen in the larval stages of Skrjabinelazia.
