Ptychohyla zoque is placed into the genus Ptychohyla because of characteristics described below. It has a green dorsal coloration with brown blotches and numerous irregular white spots, and the iris is pale pink with brown reticulations. There is a marked sexual size dimorphism, with males attaining 36.4 mm in SVL, and females 57.8 mm. Breeding males have small nonspinous nuptial excrescences, and lack glands on the venter (either ventrolateral or chest). Ptychohyla zoque may be distinguished from all other species in the genus Ptychohyla by its green dorsal coloration and iris pale pink. Although it superficially resembles P. acrochorda, P. erythromma, and P. sanctaecrucis in regard to dorsal coloration, P. zoque may be distinguished by its iris of pale pink with brown reticulations (whitish or silver in P. acrochorda, red in P. erythromma, and pale tan in P. sanctaecrucis). Ptychohyla zoque can also be distinguished by the presence of small nonspinous nuptial excrescences (dark nuptial excrescences composed of spines in P. acrochorda and P. sanctaecrucis, unknown in P. erythromma). Additionally, the new species is distinguished from P. acrochorda and P. sanctaecrucis by the absence of a chest gland in breeding males (present in the latter two species). Ptychohyla zoque and Duellmanohyla ignicolor have similar dorsal color patterns of brown blotches and numerous irregular white spots, and both share a pinkish iris. However, P. zoque can be distinguished from D. ignicolor by having nuptial excrescences and lacking noticeably thickened and extended ventrolateral gland.</p><p>Description of the holotype.

Variation in body measurements among four males and five females is summarized in Table 1. Two males (CARIE 1138, 1216) and three females (MZFC, 18667, 24005; CARIE 1215) lack the scattered white spots on dorsum; additionally, one male (CARIE 1135) and two females (MZFC 24006; CARIE 1215) have a concentration of black spots along the edge of the lower lip, and UTA A 59271 have concentrated brown spots on the chin and chest that are absent in the other specimens. Variation in vomerine teeth is as follows: 5/7 (MZFC 18667); 5/4 (MZFC 24005); 6/5 (MZFC 24006); 6/6 (UTA-A 59271); 4/5 (CARIE 1135); 5/7 (CARIE 1138); 4/5 (CARIE 1215) and 4/5 (CARIE 1216).</p><p>Advertisement call. The description of the advertisement call is based on one male (SVL = 36.1 mm) recorded at 0 140 h on 4 May 2014, when it was calling on a leaf at 92 cm above ground, over a quiet pool next to a stream, in the locality of Arroyo Zarco, Uxpanapa, Veracruz (17° 11.46’ N, 94° 29.30’ W; 216 m elevation). The advertisement call of P. zoque is very soft and difficult to hear because of noise produced by other species of frogs (mainly Exerodonta bivocata), insects, and the stream. It consists of two notes with different structure (Fig. 3); in some cases the first note is immediately followed by the second, but in some instances the notes seem to be emitted independently. The first is a short, pulsed note (n = 9), with a mean number of pulses of 9.6 ± 4 (range 3–14), mean pulse duration 0.008 ± 0.003 s (range 0.005–0.011), mean interpulse interval 0.015 ±. 0 0 7 s (range 0.005–0.027), mean dominant frequency 2516.9 ± 103.5 Hz (range 2325.6–2670.1), and mean note duration 0.249 ± 0.136 s (range 0.043–0.395). The second note is shorter than the first, and is not pulsed (n= 8), it has a mean dominant frequency 2024.1 ± 220.8 Hz (range 1808.8–2497.8), and a mean note duration 0.01 ± 0.003 s (range 0.005–0.013).</p><p>Distribution and ecology. Ptychohyla zoque occurs in evergreen tropical forest, and is known from three localities in southern Mexico in the Selva Zoque, two in southern Veracruz (Paso del Moral and Arroyo Zarco) and one in northeastern Oaxaca (Chalchijapa) (Fig. 4). Known elevational range is 76–600 m asl. Seven of the nine specimens that comprise the type series plus 20 additional specimens not collected (18 adult males, one adult female, and one juvenile) were observed at night, on branches or leaves at 20–228 cm above ground, and close to streams. Exceptions from this pattern were the female from Chalchijapa (MZFC 18667), which was sleeping on a leaf at 0 830 h near a stream, a male from Paso del Moral (CARIE 1135), which was found on the ground at 1504 h near a stream, and a juvenile of undetermined sex (not collected), which was on a leaf at 1730 h, approximately 30 m away from the nearest stream. Twenty-five of the 29 frogs were found in the dry season (March-May), whereas only four were observed in the beginning of the rainy season (June-July). All males had well developed nuptial excrescences regardless of month collected. An amplexing pair (CARIE 1215 and 1216) was collected in Arroyo Zarco, and was held overnight in a plastic bag, where 341 eggs were deposited a few hours later. Although all males appeared to be in breeding condition, only two observed on 11 March and 4 May 2014 in Arroyo Zarco, were calling from perches on leaves 228 and 92 cm above the ground, respectively.</p><p>Ptychohyla zoque is sympatric with other species of amphibians including Agalychnis moreletii, Anotheca spinosa, Incilius macrocristatus, I. valliceps, Hyalinobatrachium fleischmanni, Craugastor alfredi, C. berkenbuschii, C. loki, Eleutherodactylus leprus, Duellmanohyla chamulae, Exerodonta bivocata, Hypopachus ustus, Rhinella horribilis, Smilisca baudinii, S. cyanosticta, Lithobates vaillanti, Bolitoglossa alberchi, B. rufescens and B. veracrucis . The new species is relatively common in the evergreen tropical forests, being more abundant than other members of the family Hylidae such as Duellmanohyla chamulae, Agalychnis moreletii and Anotheca spinosa, but less abundant than Exerodonta bivocata and anurans in other families represented by Craugastor berkenbuschii and Incilius macrocristatus . This species appears to be sensitive to anthropogenic forest degradation, since it has been observed only in undisturbed evergreen tropical forest sites (Fig. 5 A and B), but not in altered environments (Fig 5 C and D) such as cattle pastures, rubber plantations and secondary forests (Aguilar- López, 2010).</p><p>Etymology. The species epithet, zoque, is an indeclinable word and refers to the Selva Zoque, a region comprised of tropical forest and covering the areas about Uxpanapa (Veracruz), Chimalapas (Oaxaca) and El Ocote (Chiapas). This region includes part of the historical range of Zoque culture, an ethnic group that has inhabited this region since pre-Columbian times.</p></div>	https://treatment.plazi.org/id/03C9000DFF99FFAB0BC1CEED6828F896	Public Domain	No known copyright restrictions apply.
