Pipa myersi is a flat-bodied frog measuring about 36 - 42mm in snout-vent length. It has a narrow triangular shaped snout in the dorsal view and a rounded mandible in the lateral view. The snout has a “transverse, chevron-shaped depression” and protrudes over the lower jaw when viewed from the side at eye level. Trueb describes the distance between the lower mandible and tip of snout as marginally less than half the distance from the snout to the front of the eye. The eyes are relatively large, widely set, and directed dorsolaterally on the head. The arms are stout and short in length. The skin is covered in densely packed, uniform-sized tubercles along the dorsum while more varied sized tubercles are spread sporadically across the head and limbs. The skin on the ventrum is also covered tubercles, depressed and of uniform size. There are four fingers on the forelimbs that have trifurcated digits with two nubby projections straddling a larger, central projection. Relative finger lengths are 1 < 2 = 4 < 3. There are five toes on the hind limbs that are almost completely webbed. Relative toe lengths are 1 < 2 < 5 < 3 = 4 (Trueb 1984).Pipa myersi is differentiated from sister species Pipa parva by having a denser collection of dorsal tubercles, a more rounded triangular shape of the snout and mandible, trifurcated digits, the absence of tubercles on the feet, lack of modification to skin around the mouth, ribs attached to transverse processes in adults, free-swimming, barbel-free, aquatic larvae, and lack of free, vestigial transverse processes for the coccyx (Trueb 1984).In life, the dorsum is a dark grayish black and the venter is a grayish yellow. The irises appear pale bronze with brown-black speckling. Newly metamorphosed individuals were observed with a dark gray color with a silvery white peritoneum. When preserved, the dorsum appears reddish to gray-brown with dark brown spotting on hands and limbs. The venter is gray with red-brown spots on pectoral and gular areas concentrated about the mandible (Trueb 1984).No variation in color has yet been documented. Some individuals were found to have six imbricate, presacral vertebrae while others were found to have seven (Trueb 1984).This frog was formally described by Linda Trueb (1984) with references to the unpublished 1965 field notes of Charles W. Myers, containing species observations and ecological descriptions. Based upon character-states among Pipiod frogs, Pipa myersi is a sister species to P. parva with the next closest relative being Pipa arrabali within the Pipa clade and genus Hymenochirus (Cannatella and Treub 1988). The species epithet refers coincidentally to both the preferred habitat of the species, derived from the Old Norse ‘myrr’ meaning bog, swamp, or deep mud and Charles W. Myers, who collected the first known series of adults of the species. Myers’ name itself is derived from the French “myre”, meaning "keeper of the swamp" (Trueb 1984).

Distribution and Habitat

Pipa myersi has been encountered at low elevations in southeastern Panama and northeastern Columbia. It has been found along two locations of the Rio Chucunaque drainage of Provincia Darien in Panama, both of which locations involved the conjunction of smaller rivers. Notes from Charles W. Myers describe habitats that included clear/brown, shallow water within vernal pools lined with leaf litter, and vast overlaying canopy cover (Trueb 1984).

As Pipiods, fertilized eggs are deposited onto the backs of females to complete development, however, after hatching the larvae leave the skin chambers and complete development as free-swimming tadpoles in open water. The aquatic larvae also lack barbels around the mouth area (Duellman and Schlager 2003). Tadpoles were often observed to be swimming near the surface of vernal pools at night as opposed to daytime, according to Myers’ field notes (Trueb 1984).

The quality and extent of suitable habitat is declining leading to greater habitat fragmentation, however, no population level data has been reported by the IUCN Red List (Solis et al. 2010).

Pipa myersi
(
Espanhol; Castelhano
)
fornecido por wikipedia ES
Pipa myersi[2] es una especie de anfibio anuro de la familia Pipidae.
Distribución geográfica
Esta especie es endémica de la provincia de Darién en Panamá. Se encuentra hasta 30 m de altitud en las cuencas de Río Ucurgantí y Río Canclón.[3] Su presencia es incierta en el norte de Colombia. Vive en zonas pantanosas.
Descripción
Pipa myersi se parece a Pipa parva, pero las puntas de sus dedos tienen tres lóbulos en lugar de cuatro. El lóbulo medio es el más desarrollado.
Comportamiento
Esta especie es acuática.
Estado de conservación
Esta especie solo se presenta en un rango pequeño y fragmentado, y la extensión y naturalidad de las áreas de humedales está disminuyendo en Panamá. La UICN lo ha clasificado como "EN" (en peligro de extinción). Está amenazada principalmente por la deforestación de las zonas de humedales debido a la tala y la expansión agrícola, pero también por el aumento de la contaminación del agua.
Etimología
Esta especie lleva el nombre en honor a Charles William Myers.

Pipa myersi est une espèce d'amphibiens de la famille des Pipidae[1].
Distribution et habitat
Cette espèce est endémique de la province du Darien au Panama. Elle se rencontre jusqu'à 30 m d'altitude dans les bassins du río Ucurgantí et du río Canclón. Sa présence est incertaine dans le nord de la Colombie[1],[2].
Elle vit dans des zones marécageuses.
Description
Pipa myersi ressemble à Pipa parva, mais les bouts de ses doigts présentent trois lobes au lieu de quatre. Le lobe médian est le plus développé[3].
Comportement
Cette espèce est aquatique.
Statut de conservation
Cette espèce n'existe que sur une aire de répartition petite et fragmentée, et l'étendue des zones marécageuses ainsi que leur naturalité est en régression au Panama. L'UICN l'a classé dans la catégorie "EN" (en danger). Elle est principalement menacée par la déforestation des zones entourant les marécages due à l'exploitation forestière et l'expansion agricole, mais aussi par l'accroissement de la pollution des eaux[2].
Étymologie
Cette espèce est nommée en l'honneur de Charles William Myers[3].
