Summary

Descriptions of four new tylenchs belonging to different genera are given : (1) Tylenchus (Tylenchus) holochmatus n.sp., (2) Tylenchorhynchus varicaudatus n.sp., (3) Trichotylenchus trilokiae n.sp., (4) Helicotylenchus pteracercus n.sp. The material of the first described species was collected in North India and that of the other new species in South India. Systematic features of new species are fully discussed and compared with those of the related forms.

Detailed descriptions are given of Tylenchorhynchus digitatus and Pratylenchus indicus described by Das (I960) from Hyderabad. The material was collected from type locality but from different hosts. Tylenchorhynchus curvus Williams, 1960, is recorded from India.

Species reported as causing damage to economically important plants in Hyderabad are : Hoplolaimus seinhorsti Luc, 1958, parasitic in cauliflower; Pratylenchus thornei Sher and Allen, 1953, parasitic in maize and Rotylenchulus reniformis Linford and Oliveira, 1940, parasitic in grape vines.
