Discussion: Arvicanthis Division. Morphological data clusters Lemniscomys with species of Arvicanthis , Pelomys , Mylomys , and Rhabdomys ( Musser, 1987 a) , which is corroborated by analysis of mitochondrial gene sequences (DNA cytochrome b, 12S and 16S rRNA gene fragments), and also includes Desmomys ( Ducroz et al., 2001) . The sequence data of Ducroz et al. also indicates that within this arvicanthine cluster, Lemniscomys is the only member of a lineage separate from that comprising Desmomys and Rhabdomys , and from another containing Arvicanthis , Mylomys , and Pelomys . Analysis of microcomplement fixation of albumin associates Lemniscomys with Pelomys , Rhabdomys , Grammomys , and Thallomys ( Watts and Baverstock, 1995 a) . Chromosomal data has been summarized for several species ( Fadda et al., 2001 b; Filippucci et al., 1986; Gautun et al., 1985). Spermatozoal morphology documented for L. striatus and L. zebra ( Breed, 1995 a; reported as barbarus ) and L. macculus ( Baskevich and Lavrenchenko, 1995) . Evolutionary history of Lemniscomys can be traced back to late Pliocene of East Africa and the genus is represented in several Pleistocene and Holocene sites in East and South Africa ( Avery, 2000; Denys, 1999).
