Abstract
Three new species of the genus Lelenchus, namely, L. aunulatus sp. n., L. crassus sp. n. and L. tenuis sp. n. are described and illustrated. L. aunulatus sp. n. comes close to L. cynodontus Husain & Khan, 1967; L. mirus Husain & Khan, 1967, and L. microdorus Chawla et al., 1969; but differs from them in having longer stylet and two pairs of cephalids on neck. L. crassuS sp. n. is closest to L. microdorus Chawla et al., 1969, but differs from it mainly in having more posteriorly located vulva. L. tenius sp. n. comes close to L. cynodontus Husain & Khan, 1967, L. minutus (Cobb, 1893) Andrassy, 1954, and L. annulatus sp. n.; but differs from them in having relatively low and rounded head, two pairs of cephalids and excretory pore located anterior to nerve ring.
