title: [Skrjabinelazia galliardi (Nematoda, Seuratoidea): morphologic complements and biological cycle].
abstract: Skrjabinelazia galliardi was previously known only from a description of the morphological characteristics of the female. Additional material being available, we were able to complete the morphological description and understand better the biology of the species. The male, the third stage larva and the fourth stage larva are described. Young females lay a very small number of third stage larvae, leading in a small scale to a reproduction of the atractide-type, that is a multiplication of the parasite directly inside the host. The old females are oviparous, but eggs contain a third stage infective larva. These eggs, after being ingested by field-crickets, hatch and without further development remain as larvae in the insect. The definitive entomophagous lizard host, which, in the field, has no opportunity to ingest the eggs, is infested by eating insects. So, the life history is intermediary between the cosmocercid like cycle (with three larval stages) and the spirurid-like cycle (with development of larval stages in an invertebrate).
