Similarities and differences in the cortical areal patterns of Galago demidovii (E. Geoffroy, 1796; Lorisidae, Primates) and Microcebus murinus (E. Geoffroy, 1828; Lemuridae, Primates).

The areal patterns of the telencephalic cortices of Galago demidovii and Microcebus murinus were compared. A very similar pattern was found in both species. This striking similarity is considered a further argument for the newly proposed phylogenetic relationship of cheirogaleids and galagos.
