Although several morphological studies support specific status of P. interparietalis , recent evidence suggests that it might be a subspecies of P. eremicus . Peromyscus interparietalis is in the eremicus species group. Three subspecies recognized.

Tail is longer than head-body length and bicolored, reddish brown above and whitish below. The San Lorenzo Deermouse is similar in size and color to the La Guarda Deermouse ( P. guardia ), but its hindfeet and tail are shorter, interparietal bone extends to suture between parietal and squama temporalis, edge of nasal is square (not rounded), zygomatic arch widens toward squama temporalis, interpterygoid fossa is narrower, palatal bone is shorter, and incisive foramina reaches first molar.
Habitat. Xeric scrubland and other island microhabitats along rocky beaches, valleys, and low plains at elevations up to c¢.485 m. Vegetation is typically sparse and dominated by chollas and cardones cacti.
Food and Feeding. San Lorenzo Deermice eat seeds, sprouts,flowers, fruits, and insects.
Breeding. Peak reproductive activity occurs in early spring, usually during March,although it can extend into summer. Gestation averages 32 days, and females generally have four offspring in a litter.
