The Yellow-throated Gartersnake, Thamnophis Thamnophis pulchrilatus is known from two localities pulchrilatus (Cope, 1885) is a gartersnake of the family in Jalisco: Municipality of : Sierra de los Natricidae endemic to Mexico that inhabits fir, pine, and Huicholes, Bajío Los Amoles (Ahumada-Carrillo et oak forests in the , Sierra Madre al., 2014) and Sierra de Tapalpa (Rossman et al., 1996). Oriental, and Trans-Mexican Volcanic Belt (Fernandez- The location provided in the present study represents Badillo et al., 2016; González-Hernández et al., 2016). a new municipality record, the third published locality According to Rossman et al. (1996) this species occurs at for the species in Jalisco, and the first one from the elevations from 2240 to 3000 m, except for one locality central portion of the state. This record fills a gap of from Tamaulipas at 1300 m that may be an error. The this species’ distribution in the state and extends its distribution of this species is fragmented substantially known distribution 97 km NW from the closest known across Mexico, with disjunct populations in the states of localities in the Municipality of Tapalpa (UTA 37113- Aguascalientes, Durango, Guanajuato, Hidalgo, Jalisco, 37118, UTA 5989, AMNH R102523, LSUMZ 59544) Mexico City, Michoacán, Morelos, Nayarit, Nuevo and 138.5 km S from the other locality in the state: Bajío León, Oaxaca, Puebla, Querétaro, Estado de México, Los Amoles, Sierra de los Huicholes, Municipality of Tamaulipas, Tlaxcala, and Zacatecas (Fernández et al., Mezquitic (UTADC 7508; Ahumada-Carrillo et al., 2006; Fernández-Badillo et al., 2016). 2014) (Table 1; Figure 2). Here we present a new record of Thamnophis The specimen was fluid preserved and it has been pulchrilatus from the state of Jalisco, Mexico. On 6 deposited in the vertebrate collection of the Centro de October 2018, while conducting diurnal fieldwork Estudios en Zoología of the Universidad de at Volcan de Tequila, 8 km SW of Tequila, Jalisco (CEZUG-R402), under collection permit FAUT- (20.8113; -103.8605, WGS-84; 2185 m), we found a 0074, granted to Fausto R. Méndez de la Cruz by the juvenile female Thamnophis pulchrilatus (CEZUG- R402; Figure 1). The snake was found under a rock in pine-oak woodland.
