This specimen was an adult; however, the specimen was reported to be in poor condition and the sex was unreported. <i>Type locality.—</i> United States: California; Monterey. <i>Subspecies.—</i> Includes <i>P. g. coolidgei</i> and <i>P. g. gambelii</i> based on the findings of Greenbaum et al. (2017), as well as <i>P. m. margaritae</i> according to the phylogenetic relationships of samples examined herein. Although we were not able to examine many of the subspecies that potentially are referable to <i>P</i>. <i>gambelii</i>, we tentatively assign the following 15 subspecies recognized by Hall (1981) to <i>P</i>. <i>gambelii</i>: <i>anacapae</i>, <i>assimilis</i>, <i>catalinae</i>, <i>cineritius</i>, <i>clementis</i>, <i>coolidgei</i>, <i>dorsalis</i>, <i>dubius</i>, <i>elusus</i>, <i>exiguous</i>, <i>exterus</i>, <i>gambelii</i>, <i>geronimensis</i>, <i>hueyi</i>, <i>magdalenae</i>, <i>margaritae</i>, <i>sanctaerosae</i>, <i>santacruzae</i>, and <i>streatori</i>. <i>Diagnosis.—</i> Sides and upperparts ochraceous or ochraceous buff mixed with dusky coloration; underparts white; ears dusky; tail short to medium in length and bicolored (brown to dusky on top and white below). Medium sized for species group but possessing a longer than normal tail; measurements obtained from Osgood (1909), for several of the subspecies now assigned to <i>P</i>. <i>gambelii</i>, indicated a total length averaging 171.5 mm; (range 148–195 mm) and tail length averaging 84.5 mm (range 64–105 mm). Skull slightly smaller than that found in nearby populations of <i>P</i>. <i>maniculatus</i> and <i>P</i>. <i>sejugis</i> (Burt 1932). Genetically (mitochondrial sequences; Hogan et al. 1997; Walker et al. 2006; Greenbaum et al. 2017; this study), <i>P. gambelii</i> has been shown to differ from other populations from the northwestern and western United States, formerly assigned to <i>P</i>. <i>maniculatus</i> but based on results presented herein (see Table 2) have been assigned to <i>P</i>. <i>sonoriensis</i> as well as other regional members of the <i>P</i>. <i>maniculatus</i> species group now assigned to <i>P</i>. <i>keeni</i>. In this study, data from the <i>Cyt</i> b analysis indicated that <i>P. gambelii</i> differed from <i>P</i>. <i>keeni</i>, <i>P</i>. <i>labecula</i>, <i>P</i>. <i>maniculatus</i>, <i>P</i>. <i>sonoriensis</i>, and <i>P</i>. <i>sejugis</i> by 3.71%, 3.80%, 4.90%, 4.55%, and 2.05%, respectively. Genetic differentiation (= 0.98%) based on DNA sequences obtained from 41 individuals of <i>P</i>. <i>gambelii</i> was among the lowest intraspecific values obtained in this study. <i>Distribution.—</i> Based on data presented herein and from Greenbaum et al. (2017), the distribution of <i>P</i>. <i>gambelii</i> should include northern California (San Francisco Bay Area and San Joaquin Valley) and extreme western-central region of Nevada (west of the Sierra Nevada range), southward along coastal California to the southern tip of Baja California del Sur, Mexico. Further, it appears that samples from the northern portion of the former distribution of <i>P</i>. <i>m</i>. <i>gambelii</i> (as depicted by Hall 1981), specifically those from central Oregon and east-central Washington, should be assigned to <i>P</i>. <i>sonoriensis</i>. Although we were not able to examine many of the insular subspecies occurring along the California and Baja California coasts, presumably based on geographic location, those subspecies would be assignable to <i>P</i>. <i>gambelii</i>. <i>Comparison.—</i> A member of the <i>P. maniculatus</i> species group. Similar in most characteristics to other members of the <i>P. maniculatus</i> species group; although smaller in size compared to <i>P</i>. <i>keeni</i> and <i>P</i>. <i>sonoriensis</i>. Hooper (1944) noted morphological distinctions between populations <i>P. gambelii</i> and populations north of the San Francisco Bay (now recognized as <i>P. sonoriensis rubidus</i>); with samples of <i>P. s. rubidus</i> averaging larger than <i>P. g. gambelii</i> in the following measurements: total length, tail length, length of braincase, length of nasals, and length of hindfoot. In addition, Hooper (1944) noted that samples referable to <i>P. s. rubidus</i> were darker and more reddish in color than were individuals referable to <i>P</i>. <i>gambelii</i>. <i>Remarks.—</i> Forty-six samples were examined in this study that are assignable to <i>P</i>. <i>gambelii</i>. Of these samples, the closest to the type locality, examined herein, was approximately 50 km northeast of Monterey, California, United States. Chromosomal variation within <i>P</i>. <i>gambelii</i> is extensive as the number of autosomal arms (fundamental number, FN) ranges from 72–86 (Bradshaw and Hsu 1972; Bowers et al. 1973; Calhoun et al. 1988) with <i>P</i>. <i>g</i>. <i>cooledgii</i> being reported as monomorphic (FN = 76; Calhoun et al. 1988) and <i>P</i>. <i>g</i>. <i>gambelii</i> being polymorphic (FN = 72–86; Calhoun et al. 1988). The FNs reported for <i>P</i>. <i>gambelii</i> overlap those reported for <i>P</i>. <i>labecula</i>, <i>P</i>. <i>maniculatus</i>, and <i>P</i>. <i>sonoriensis</i>; but differ substantially from those observed for <i>P</i>. <i>melanotis</i> (FN = 62, Hsu and Arrighi 1968; Bowers et al. 1973), <i>P</i>. <i>polionotus</i> (FN = 69–71; Te and Dawson 1971), and <i>P</i>. <i>sejugis</i> (FN = 76; Smith et al. 2000). Although karyotypic, allozymic, and mtDNA restriction fragment length polymorphism datasets (Lansman et al. 1983; Calhoun et al. 1988) could not distinguish among populations of <i>P</i>. <i>maniculatus</i> from California and Baja California (now referable to <i>P</i>. <i>g</i>. <i>coolidgei</i>, <i>P</i>. <i>g</i>. <i>gambelii</i>, <i>P</i>. <i>s</i>. <i>rubidus</i>, and <i>P</i>. <i>s</i>. <i>sonoriensis</i>), recent genetic studies (Hogan et al. 1997; Dragoo et al. 2006; Walker et al. 2006; Greenbaum et al. 2017) indicated that <i>P</i>. <i>g</i>. <i>coolidgei</i> and <i>P</i>. <i>g</i>. <i>gambelii</i>, ranging from central California to Baja California del Sur were species distinct from <i>P</i>. <i>s</i>. <i>rubidus</i>, and <i>P</i>. <i>s</i>. <i>sonoriensis</i>. In addition, <i>P</i>. <i>gambelii</i> presumably was more closely related to <i>P. sejugis</i> and <i>P</i>. <i>keeni</i> than to other populations of <i>P</i>. <i>maniculatus</i> from the western United States (Avise et al. 1979; Gunn and Greenbaum 1986; Smith et al. 2000; Greenbaum et al. 2017); although Hogan et al. (1997), Chirhart et al. (2005), and this study posited that <i>P</i>. <i>sejugis</i> is sister to <i>P</i>. <i>keeni</i> <i>.</i> Although they did not include samples of <i>P. sejugis</i>, other studies (Dragoo et al. 2006; Kalkvik et al. 2012) demonstrated a close relationship between samples of <i>P. keeni</i> and <i>P. m. coolidgei</i> and postulated that coastal populations of <i>P. maniculatus</i> might represent a distinct genetic form. In addition, Kalkvik et al. (2012) reported that populations of <i>P. maniculatus</i> from southern California and Baja California (= <i>P</i>. <i>gambelii</i>) occupy significantly different climatic niches and ecozones than do populations of <i>P. maniculatus</i> from north of the San Francisco Bay (= <i>P</i>. <i>sonoriensis</i>). Herein, samples of <i>P</i>. <i>gambelii</i> exhibited extremely low genetic distance value with <i>P. sejugis</i> compared to other species examined. Estimated divergence times indicated that <i>P. gambelii</i> last shared a common ancestor with members of the <i>P. keeni /P. sp</i> clade approximately 1.55 mya. Further it appears that the <i>P. gambelii / P. sejugis / P. keeni</i> lineage diverged from other taxa formerly assigned to <i>P. maniculatus</i> (<i>P</i>. <i>labecula</i>, <i>P. maniculatus</i>, <i>P</i>. <i>polionotus</i>, and <i>P</i>. <i>sonoriensis</i> approximately 1.80 mya. As discussed earlier, <i>P</i>. <i>gambelii</i> appears to be sympatric with samples of <i>P</i>. <i>sonoriensis</i> in western Nevada (near NAS Fallon Air Force Base) and at two separate localities in east-central California (one in Mono County and one in Tuolumne County). Additional data are need from these areas to determine if these genetic species (see Bradley and Baker 2001; Baker and Bradley 2006) are behaving as biological species (Mayr 1942) as well as genetic species.
