THE GENUS AXONCHIUM (NEMATODA : BELONDIRIDAE) IV. SPECIES WITH VAGINAL SCLEROTIZATION (PART 2) BY PANKAJAM NAIR and A. COOMANS Instituut voor Dierkunde, Rijksuniversiteit Gent, Belgium The species of Axonchium with vaginal sclerotization, but without disc-like structure between vulva and vagina are redescribed. This group is less uniform than that treated in the previous paper, it comprises the following species : A. coronatum (de Man, 1906), A. leptocephaluin Altherr, 1953, A. vaginatum Jairajpuri, 1965, A. valvulatum n.sp. and possibly A. macrophallum Thorne, 1939. Males, when present, have long and comparatively slender spicules. This fourth paper of the series on the genus Axonchium Cobb, 1920, deals with those species that possess vaginal sclerotization, but lack a disc-shaped structure between vulva and vagina. These species do not form such an homogeneous group as those possessing a disc-like structure (cf. Nair, 1973), they nevertheless have a number of characters in common. The sclerotization is variable in shape according to the species; it may be rather weakly developed, as in A. coronatum and A. leptocephalum, or well developed as in A. vaginatum and A. valvulatum n.sp. The sheath around the oesophagus consists of parallel, straight muscle bands. Anterior sexual branch varies from about
