Isthmura naucampatepetl (Parra-Olea, Papenfuss & Wake 2001)

Description ( Inglês )

fornecido por AmphibiaWeb articles
Isthmura (Pseudoeurycea) naucampatepetl is a small member of the Isthmura (Pseudoeurycea) bellii complex. It is distinguished from its congeners by its coloration/pattern consisting of a pair of prominent, pink, rather than orange spots, on the head, a pair of similarly colored triangular shoulder spots followed by a series of ten pairs of small costal spots and a distinctive U-shaped spot above the pelvic region. The largest male attained a SVL of 82.1 mm (smallest male 67.6 mm) and the largest female attaining 82.9 mm. Broadly rounded, large snout with protuberant eyes. Head is broad, 14.3-16 svl. Adpressed limbs meet, slightly overlap, or slightly fail to overlap in males but fail to overlap by one to one-half costal folds in females. Fingers in order of decreasing length of 3-2-4-1; toes in order of decreasing length 3-4-2-5-1. Tails 74-84% SVL. Premaxillary teeth 3-4 and slightly enlarged in males, indistinguishable in females (Parra-Olea et al. 2001).

All specimens were found by scraping the surface of roadcut banks which consisted of moist soil with a dry outer crust. Most of these banks were shaded.

Isthmura naucampatepetl ( Alemão )

fornecido por wikipedia DE

Isthmura naucampatepetl ist ein extrem seltener oder bereits ausgestorbener Salamander aus der Gattung Isthmura innerhalb der Familie der Lungenlosen Salamander. Er ist oder war in der Region des Vulkans Cofre de Perote im mexikanischen Bundesstaat Veracruz endemisch.

Merkmale

Isthmura naucampatepetl ist nur durch fünf Exemplare bekannt geworden. Davon hat das größte Männchen eine Kopf-Rumpf-Länge von 82,1 mm und das kleinste eine Kopf-Rumpf-Länge von 67,6 mm. Das größte Weibchen weist eine Kopf-Rumpf-Länge von 82,9 mm auf. Die Länge des Schwanzes macht 74 bis 84 Prozent der Kopf-Rumpf-Länge aus. Die Oberseite ist schwarz, die Unterseite ist hellgrau. Der Kopf ist durch zwei hervorstehende rosa Flecken charakterisiert. Auf der Schulter befinden sich zwei rosafarbene Flecken gefolgt von elf Paar cremerosa Rippenflecken und einem auffälligen u-förmigen Fleck der gleichen Farbe über der Brustregion. Der Kopf ist breit. Die lange Schnauze ist weitgehend gerundet. Die Augen sind hervorstehend.

Lebensraum

Der Lebensraum sind Mischwälder mit Kiefern- und Eichenbeständen sowie reichlicher Grasvegetation in Höhenlagen zwischen 2500 und 3000 m. Der Name Naucampatepetl ist in der Sprache Nahuatl die Bezeichnung für den Cerro Cofre de Perote. Die Typuslokalität liegt in der Umgebung dieses Berges.

Lebensweise

Über seine Lebensweise ist nur wenig bekannt. Diese Art ist unabhängig von Gewässern, da sie kein aquatiles Kaulquappenstadium durchläuft, sondern eine direkte Entwicklung der Eier stattfindet.

Status

Die IUCN stuft diese Art in die Kategorie vom Aussterben bedroht (critically endangered) ein. Der letzte Nachweis stammt aus den 1980er-Jahren und trotz intensiver Suchen in den Jahren 2003 und 2004 konnte dieser Salamander nicht mehr wiederentdeckt werden. Der Lebensraum in der Typuslokalität ist durch Rodung, landwirtschaftliche Nutzung (insbesondere Kartoffelanbau) und die Ausweitung menschlicher Siedlungen erheblich in Mitleidenschaft gezogen worden und stark degradiert.

Isthmura naucampatepetl ( Inglês )

fornecido por wikipedia EN

Isthmura naucampatepetl, commonly known as the Cofre de Perote salamander, is a species of salamanders in the family Plethodontidae. It is endemic to the Sierra Madre Oriental in central Veracruz, Mexico, where it is known from between Cofre de Perote and Cerro Volcancillo,[1][3][4] a satellite peak of Cofre de Perote.[2]

Etymology

The specific name naucampatepetl is Nahuatl name for Cofre de Perote.[2]

Description

Adult males measure 68–82 mm (2.7–3.2 in) and females up to 83 mm (3.3 in) in snout–vent length (SVL). The tail is slender and shorter than SVL; it tapers gradually but has a blunt tip. The body is moderately robust. The head is prominent and the eyes are large and relatively protuberant. The snout is large and broadly rounded. The limbs are long and robust. The digits are well developed, and there is no appreciable webbing. The coloration is striking, with solid black background color and with bright pink to pinkish-cream dorsal spots: there is a pair of rounded spots on the back of the head, about the size of the eyeball in diameter, a small mid-dorsal spot in the neck, and a pair of large spots at the level of the forelimbs. These larger spots are followed by 11 pairs of small spots. Finally, there is a conspicuous U-shaped mark behind the hips, pointing backward. The venter is pale gray to dark gray.[2]

Habitat and conservation

Its natural habitat is pine-oak forest at elevations of 2,500–3,000 m (8,200–9,800 ft) above sea level, with plenty of bunch grass.[1] All specimens in the type series were found on roadside banks, under a surface layer of moist soil with a somewhat dry outer crust.[2]

This species is known from only six specimens. An individual was photographed in 2015, but surveys have failed to locate the species. [1] Extensive logging, farming, and expanding human settlements have led to loss of much of the original habitat, and what remains is very degraded. The IUCN SSC Amphibian Specialist Group considers Isthmura naucampatepetl critically endangered.[1]
