Description

provided by AmphibiaWeb articles
Bolitoglossa robinsoni is a relatively large and stout-bodied species of salamander. The standard length (from the snout to the posterior angle of the vent) ranges from 45 to 63 mm and total length is approximately 122 mm. The head is well defined from the neck and the snout is largely rounded but not protruding. Nostrils are diminutive and nasolabial protuberances are weakly developed. Eyes are fairly large as they project slightly beyond the lateral margins of the head and are relatively frontal in orientation. B. robinsoni averages 6 premaxillary teeth, 31-34 maxillary teeth, and 10-12 vomerine teeth aligned in a single row. A sublingual fold is not present. Limbs are stout and moderately long; the distance between adpressed limbs (limb interval) is 2.0 costal grooves. Hands and feet are large and slightly webbed, with shortened digital tips and well-developed subterminal pads. In order of decreasing length, fingers are 3>4>2>1 and toes are 3>4>2>5>1. Postiliac glands are not visible. In preservative, this species has a dark brownish-black ground color, but it has such a quantity of pale spots that it appears light-colored. Along the trunk an intricate pattern is present of alternating light yellow and dark color. Costal grooves are mostly dark while intercostal folds are mainly light. Limbs and tail are marbled with dark brown and yellowish gray. The venter and throat are primarily pale in color; however, the venter is also somewhat mottled and the throat displays punctate melanophores. Tail venter is dark with jagged lighter spots.Bolitoglossa robinsoni differs from all other salamanders in the region by virtue of its larger size combined with extensive yellow spotting and relatively long and moderately webbed digits.The species is named in honor of the late Douglas C. Robinson, who surveyed amphibians and reptiles in Costa Rica and consolidated the University of Costa Rica’s specimen collection. He was the mentor of most of today's Costa Rican herpetologists.This species was previously referred to as sp. nov. 5 in Wake (2005). It may be a species complex of as many as four or five species. Sympatric with B. pygmaea on the Fábrega Massif.

Répartition

Cette espèce est endémique de la cordillère de Talamanca. Elle se rencontre entre la province de Puntarenas au Costa Rica jusqu'à la province de Bocas del Toro au Panama entre 2 300 et 3 355 m d'altitude[1].

Description

Le mâle holotype mesure 123,2 mm de longueur totale dont 63,5 mm de longueur standard et 59,7 mm pour la queue. Sur les 31 spécimens mesurés lors de la description, la longueur standard varie de 26,2 à 72,5 mm et la queue de 16,3 à 70,7 mm[2].

Étymologie

Son nom d'espèce, robinsoni, lui a été donné en l'honneur de Douglas C. Robinson à qui l'on doit une enquête importante sur les amphibiens et reptiles du Costa Rica et qui a inspiré nombres d'herpétologistes costaricains[3].

Herpetologie

Bolitoglossa robinsoni is een salamander uit de familie longloze salamanders (Plethodontidae). De soort werd voor het eerst wetenschappelijk beschreven door Federico Bolaños en David Burton Wake in 2009.[1] De soortaanduiding robinsoni is een eerbetoon aan Douglas C. Robinson.

Verspreiding en habitat

De salamander komt voor in delen van Midden-Amerika en leeft in de landen Costa Rica en Panama.[2]

Bolitoglossa robinsoni wordt tot maximaal 72,5 millimeter lang. De soort komt voor op een aantal locaties in de Cordillera de Talamanca op het Continental Divide in het grensgebied tussen Costa Rica en Panama. Nevelwouden boven de 2400 meter hoogte boven zeeniveau en páramo vormen het leefgebied. Bolitoglossa robinsoni komt op het Fábrega-massief samen voor met de kleinere verwante Bolitoglossa pygmaea.[3]
