4059061478B6559FA517E30F28F3908A.taxon	diagnosis	Diagnosis. Assigned to the genus Pseudoeurycea based on the presence of a sublingual fold, comparatively short fifth toe compared to the fourth, limited foot webbing, relatively large size, and mitochondrial DNA sequences. Morphologically, we distinguish the new species from the other salamanders that occur in the region and from the others of the genus Pseudoeurycea based on size of the body and tail, limb length, digit shape, shape and size of the head, and especially by external coloration (dorsal and ventral coloration of head, body and tail). Pseudoeurycea jaguar is easily distinguished from the other species of the genus Pseudoeurycea by its unique color pattern (Figs 1, 4). Based on mtDNA, this new species is closely related to members of the P. juarezi group (sensu Canseco-Marquez and Parra-Olea 2003; Parra-Olea et al. 2004). It is distinguished from species of the P. juarezi group by its larger body size (SVL males: P. aurantia SVL 40.2 - 45.0, P. jaguar sp. nov. 58.0 - 58.7 mm, P. juarezi 44.0 - 51.3 mm, P. ruficauda 24.2 mm, P. saltator 40.0 - 42.3 mm; females: P. aurantia 41.5 - 44.1 mm, P. jaguar sp. nov. 42.4 - 71.0 mm, P. juarezi 38.5 - 48.0 mm, P. ruficauda 38.2 mm, P. saltator 33.4 - 41.2 mm; Tables 1 and 2) and wider head (HW males: P. aurantia 9.9 - 11.2 mm, P. jaguar sp. nov. 13.7 - 15.1 mm, P. juarezi 10.0 - 12.6 mm, P. ruficauda 6.7 mm, P. saltator 9.5 - 10.3 mm; females: P. aurantia 10.3 - 10.7 mm, P. jaguar sp. nov. 11.0 - 17.6 mm, P. juarezi 9.4 - 12.5 mm, P. ruficauda 8.5 mm, P. saltator 3.8 - 9.1 mm. Females have a relatively longer tail (TL / SVL females: P. aurantia 0.86 - 0.90, P. jaguar sp. nov. 0.93 - 1.25, P. juarezi 0.70 - 1.12, P. ruficauda 0.99, P. saltator 0.88 - 0.92). Pseudoeurycea jaguar sp. nov. has more maxillary and premaxillary teeth (mean MT + PMT males: P. aurantia 69, P. jaguar sp. nov. 85.5, P. juarezi 73, P. ruficauda 31, P. saltator 67; females; P. aurantia 74, P. jaguar sp. nov. 92.6, P. juarezi 67, P. saltator 73) and vomerine teeth (mean VT males: P. aurantia 25, P. jaguar sp. nov. 30.5, P. juarezi 23.3, P. ruficauda 17, P. saltator 26; females; P. aurantia 22, P. jaguar sp. nov. 30.3, P. juarezi 22, P. saltator 22). The head of P. jaguar is longer and wider than that of other species (HL males: P. aurantia 9.9 - 11.2, P. jaguar sp. nov. 13.7 - 15.1 mm, P. juarezi 10.0 - 12.6 mm, P. ruficauda 6.7 mm, P. saltator 9.5 - 10.3 mm; females: P. aurantia 10.3 - 10.7 mm, P. jaguar sp. nov. 11.0 - 17.6 mm, P. juarezi 9.4 - 12.5 mm, P. ruficauda 8.5 mm, P. saltator 3.8 - 9.1 mm; HW males: P. aurantia 6.3 - 6.8, P. jaguar sp. nov. 9.8 - 10.3 mm, P. juarezi 6.2 - 7.9 mm, P. ruficauda 4.4 mm, P. saltator 6.3 - 6.7 mm; females: P. aurantia 6.1 - 6.7 mm, P. jaguar sp. nov. 7.8 - 12.0 mm, P. juarezi 5.9 - 7.8 mm, P. ruficauda 6.1 mm, P. saltator 5.4 - 6.7 mm). No other species of Pseudoeurycea from Veracruz or Puebla has such large, extensively webbed feet and long limbs. The new species is further distinguished from all members of the Pseudoeurycea juarezi group, as well as from all other species of Pseudoeurycea and all salamander species from central Veracruz, by color pattern. Pseudoeurycea jaguar has irregular yellow mottling on the dorsum on a brown or nearly black background. In P. aurantia the ground color is reddish brown with bright orange blotches or mottling present on the dorsum; these blotches coalesce on the tail (Fig. 1 A), and some individuals have small dark spots on the tail and dorsum. Pseudoeurycea saltator has a uniformly dark gray-brown dorsal ground color that is invariably overlain by a paler yellow or golden mid-dorsal stripe (Fig. 1 B). Pseudoeurycea juarezi typically has yellow-brown dorsal coloration on the head and forming a dorsal band to the tip of the tail, with scattered black spots on the dorsum and tail (Fig. 1 C); the color pattern in this species can be variable, some specimens have small dark spots on a yellowish background (Fig. 1 D) while others are darker brown or reddish-brown dorsally with yellow or golden mottling on the tail. Dorsal coloration in P. ruficauda is orange-tan with coppery-gold highlights that are mixed with black (Fig. 1 E). The ventral part of the tail of P. jaguar is paler than the dorsal part (lead gray), darkening towards the tip, with very small and clear flecks evenly distributed along the median portion of the venter. Both P. melanomolga and P. gadovii have some version of yellowish spots on a dark background, but the spots in these species are arranged in regular rows unlike the mottling seen in P. jaguar. Pseudoeurycea lynchi has greenish, rather than yellow, blotches and mottling and tends to show less background color compared to P. jaguar. Pseudoeurycea nigromaculata also typically shows less background color and often is primarily yellowish on the tail, and P. granitum has irregular blotches and a pale interorbital bar that are lacking in P. jaguar.	en	Cazares-Hernandez, Erasmo, Jimeno-Sevilla, H.

4059061478B6559FA517E30F28F3908A.taxon	distribution	Distribution and natural history. Pseudoeurycea jaguar sp. nov. is known only from Sierra de Zongolica (Fig. 5 A). It is found in a mature coniferous forest (Fig. 5 B, C) at 2,360 - 2,367 m, which is dominated by Cupressus benthamii, Pinus patula, Alnus acuminata, and Saurauria leucocarpa with an understory of Fuchsia microphyla, Rubus sp., Licianthes synanthera; and herbaceus plants including Didymaea alsinoides, Chusquea mulleri and Begonia oaxacana. There is an abundant presence of epiphytes, including Tillandsia imperialis and Elaphoglossum paleaceum, with extensive growth of mosses. Pseudoeurycea jaguar sp. nov. is mainly an arboreal species with nocturnal habits. The species was observed active at night on trees, shrubs, rocks, herbaceous plants, and moss and was also observed moving on the ground. Most of the trees where P. jaguar was observed contained layers of moss and bromeliads. By day, we found P. jaguar sp. nov. hidden behind or within the layers of moss that cover the trunks of the trees, in particular two species of moss (Ptychomitrium sp. and Anacolia menziesii). Other species of plethodontids that share habitat with P. jaguar sp. nov. in the study site are Aquiloeurycea cafetalera, Chiropterotriton sp., Isthmura gigantea, Parvimolge townsendi, Thorius sp. and T. troglodytes.	en	Cazares-Hernandez, Erasmo, Jimeno-Sevilla, H.

4059061478B6559FA517E30F28F3908A.taxon	etymology	Etymology. The specific epithet jaguar is a noun in apposition and refers to the similarity between the dorsal color pattern of the salamander and that of the jaguar (Panthera onca). In the last three years the presence of this endangered feline has been recorded in some places in the Sierra de Zongolica and it seems appropriate to honor this emblematic species in the region.	en	Cazares-Hernandez, Erasmo, Jimeno-Sevilla, H.
