Nematodes of high altitudes in India. IV. Two new species of Belondiridae Thorne, 1939 (Dorylaimida)

Abstract

Two new species of Belondiridae, Dorylaimellus himalayensis and Axonchium manalicum from high altitudes in India are described. The former comes close to D. graminis Kruger, 1965, but differs in its longer body, attenuated spear and differently shaped tail. Axonchium manalicum n. sp. comes closest to A. metobtusicaudatum (S. Stekhoven & Teunissen, 1938) Nair & Coomans, 1973, A. heynsi Nair, 1973 and A. transkeiense Nair, 1973; it differs from the first mainly in its longer body, longer prerectum, longer and stouter spicules; from A. heynsi and A. transkeiense the new species mainly differs in its longer anterior uterine sac, differently shaped spicules and in having the last ventromedian supplement within spicular range. A key to the species of Dorylaimellus Cobb, 1913 is provided.
