andrewsi geespei pigotti stromeri africanus indicus johanesi . spp Phiomys Kochalia Paraphiomys Apodecter Neosciuromys Paraulacodus Paraulacodus Thryonomys acters are binary whereas seven are multistate. Amongst the latter, characters 5, 12, 13, 14, 19 and 22 have two derived states and character 17 has three. Owing to the lack of a priori information, the weight of all characters was chosen to be identical (1). Using the same line of thought, there is no rationale to order the multistate characters and therefore all the possible transformations of one state into another cost one step.

PROCEDURE

The software of phylogenetic reconstruction by parsimony analysis used was PAUP v.3.1.1 ( Swofford, 1993). The relatively high number of terminal taxa and characters precluded exact tree building, so a heuristic search by stepwise addition (‘closest’ option) was performed.
