New and little known Laimydorinae species from Fynbos in the south-western Cape (Nematoda: Dorylaimidae)

Abstract

Calcaridorylaimus sirgeli n.sp. is described from Cape Fynbos in mountains in the south-western Cape Province. It differs from all known species in the genus by the presence of advulval ornamentation, and is compared in detail with Calcaridorylaimus signatus (Loot, 1975) and Calcaridorylaimus ruwenzorii (De Coninck, 1935). A single specimen of Drepanodoryiaimus williamsi (Heyns & Kruger, 1983) is compared with specimens from the Transvaal and Mauritius. Mesodorylaimus sp. cf. graciosus Andràssy, 1986 is reported from South Africa for the first time.
