Systematics of the painted spiny pocket mouse Liomys pictus (Rodentia : Heteromyidae) from Colima and southern Jalisco, Mexico

Collected Liomys pictus from southern Jalisco and Colima. Analysis of these collections suggested that the ranges of L. p. pictus and L. p. plantinarensis overlap geographically with apparently a small amount of introgression occurring. The purpose of this paper is to analyze patterns of morphological variation among populations of Liomys pictus from southern Jalisco and Colima, and to assess the extent of morphological differentiation between the subspecies L. p. pictus and L. p. plantinarensis in this area of Mexico.
