Cataguana Salamander

Bolitoglossa cataguana Townsend, Butler, Wilson & Austin 2009

Description

provided by AmphibiaWeb articles
A single male specimen measures 40.4 mm in SVL, 75.0 mm in TL. Four female specimens range from 35.3-49.7 mm in SVL, with an average SVL of 43.9 mm and average TL of 75.3 mm. Bolitoglossa cataguana has 13 costal grooves. The snout is truncated when viewed dorsally and is rounded in profile. Labial protuberances are well-developed. Mental gland is absent. Suborbital groove and postorbital groove are distinct. Gular fold is well-defined. The female holotype has 6 premaxillary teeth located just posterior to the lip, as well as 51 maxillary teeth that extend to the posterior half of the orbit and are aligned with the premaxillary teeth but separated by a small gap. Twenty-one vomerine teeth are present in two arched series, extending to the edges of the internal nares. The forelimbs are relatively slender. Hind limbs are broader than long. The fingers are moderately webbed, except for one to two phalanges on the third finger. The toes are free of webbing. The relative length of fingers is 1

Distribution and Habitat

provided by AmphibiaWeb articles
B. cataguana is known from the frontier community of Cataguana in the Lower Montane Wet Forest formation between 1800 to 2080 m above sea level on the western side of the Parque Nacional Montaña de Yoro, central Honduras. The holotype was collected from a trail above Quebrada Cataguana in the Parque Nacional Montaña de Yoro, at 1850 m elevation. All specimens were collected from lightly disturbed Mixed Cloud Forests (Townsend et al. 2009).

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Two juveniles were collected in March, on small plants about 0.5 m above the ground. An adult female was seen sleeping during the day under a log. Other specimens were collected during the night when the animals were active on a steep hillside. They were all found on plants 0.5 to 3.0 m above the ground (Townsend et al. 2009).

Distribution in Honduras

Bolitoglossa cataguana, also known as the Cataguana salamander,[3] is a species of salamander in the family Plethodontidae.[1][3][4] It is endemic to Honduras and known from near Cataguana in the Marale municipality, Francisco Morazán Department.[1][4]

Description

The type series consists of the holotype, which is an adult female measuring 45 mm (1.8 in) in snout–vent length, three sub-adult and adult females between 35 and 50 mm (1.4 and 2.0 in), a sub-adult male measuring 40 mm (1.6 in), and two juveniles. There are 13 costal grooves. The sub-digital pads are well-developed and the toe tips are bluntly rounded. The tail, measuring 32 mm (1.3 in) in the holotype, is constricted basally and appears "swollen" after the constriction.[2][3]

Habitat and conservation

The type series was collected in lightly disturbed, mixed cloud forest on the edge of the Montaña de Yoro National Park at elevations of 1,800–2,080 m (5,910–6,820 ft) above sea level. Individuals were found active in vegetation up to 3 metres above the ground or resting during the daytime under a log. Coloration may vary by time of the day; during the daytime, the holotype was dorsally gray-brown with pale ocher cast and scattered dark brown punctations, whereas at the night it was pale grayish tan with pale pink cast.[2][3]

Bolitoglossa cataguana is probably endemic to the Montaña de Yoro National Park. Its small range, rarity, and the threat posed by habitat loss caused by agricultural expansion, including marijuana plantations, warrant its listing as "critically endangered".[1]
