Abstract

This paper deals with description of two new species of Myctolaimus Cobb, 1920 obtained from ditch samples from Kishtwar, Jammu and Kashmir, India. M. neolongistoma sp, n. is characterized by its medium-sized body (L= 0:60-0.67; a= 217-26.1;b- 4.8-5.1;c= 4.8-5.3, c'= 6.9-7.0; V= 48.2-51.3) with fine longitudinal striations, petalloid cheiforhabdions, isthmus equal or slightly smaller than basal bulb, and males with 20-24 µm long spicules and ten pairs of genital papillae. The other species, M. kishtwarensis sp. n., is characterized by its large body (L= 0.86-1.14; a= 25.1-30.9; b= 5.5-6.8; c= 4.4-5.9; d = 7.2-10.2; V= 43.1-47.8), six radiating cheilorhabdial arms, isthmus larger than basal bulb and males with 24-28 µm long spicules, and nine pairs of genital papillae
