. It has been discovered that ''P. amicus'' and ''P. gerbillius'' are closely related as sister species. However, ''P. gerbilllius'' belongs to the clade ''Phyllotis'', which contains ''amicus'', ''andium'', ''and gerbellius'' while ''wolffsohni'' belongs to ''Tapecomys''. Measurements of 35 ''P. gerbillus'' adults were as follows; total length of 83.2 ± 0.72 (77-96 in ); tail 78.1 ± 1.13 (62-90 in); greatest length of skull, 23.44 ± 0.09 (22.2 - 24.5 in); zygomatic breadth, 12.32 ± 0.04 (11.7 -13.0 in) and weight, 17.37 ± 0.50 (14-25).
