MORPHOMETRIC VARIATION IN THE MANDIBLE OF MICROTUS ARVALIS AND MICROTUS AGRESTIS (RODENTIA: CRICETIDAE) by J. VAN DER KOOIJ, M. GILLHAM, R. J. POST, TH. HEIJERMAN and M. D. WILSON (Animal Taxonomy Section, Wageningen Agricultural University, PO Box 8031, 6700 EH Wageningen, The Netherlands
morphometrics of the spicules are extremely variable within the group but they presumably show a limited intraspecific variation. Thus, their study has taxonomical interest to separate some taxa and, in particular, close species belonging to the same genus.
The dorylaims, the representatives of the order

synonymised with Oscheius Andrássy, 1976 by Ye et al . ( 2010 ). Inadequate morphological characterisation, morphometrics and some errors in the original description of O. chongmingensis encouraged us to re-describe this species from the Tumian strain and to add some data on its entomopathogenicity. We

infections of cereals by cyst nematodes were found. Although the morphology of this was very similar to H. avenae , they differed in a few morphometric characters and the presence of an underbridge in the cysts. Based on these differences, the nematode was described as H. filipjevi by Madzhidov ( 1981
