[Herpetology • 2011] Larutia nubisilvicola | จิ้งเหลนป่าเมฆ -เขานัน • A New Species of Larutia (Squamata: Scincidae) from Peninsular Thailand

Abstract

During an expedition to study the biodiversity of the cloud forest of the Upper Khao Nan Mountain Range of Nakhon Si Thammarat in April 2007, a Larutia sp. was found. This proved to be morphologically distinct from any other known species of Larutia and is now described as Larutia nubisilvicola sp. nov.

Key words: Reptilia, Lepidosauria, Squamata, Lacertilia, Sauria, Scincomorpha, Scincidae, Larutia, Larutia nubisilvicola sp. nov., Southeast Asia, Thailand, taxonomy.

Holotype: THNHM 11799 female.

Paratypes: THNHM 11797 female, THNHM 11798 male, THNHM 11800 female; collected by T. Chan-ard, M. Cota, S. Makchai & S. Lhaoteaw on 20 April 2007. 

Diagnosis: A small species of Larutia. Mid-body scale row is 24. Possesses 4 supraoculars, 6 supralabials and 5 infralabials. The first infralabial is separate from, but appears as an extension of the mental. The postmental contacts the first and second infralabials as well as the first pair of chin shields. A single gular scale is present between the second pair of chin shields.

Etymology: Larutia nubisilvicola is named as an inhabitant of the cloud forest, where it is found.

[Herpetology • 2006] กบชะง่อนผาภูหลวง | Odorrana aureola | Phu Luang Rock Frog • Cascade Frog from Northeastern Thailand

กบชะง่อนผาภูหลวง

Odorrana aureola Stuart, Chuaynkern, Chan-ard & Inger, 2006

Abstract

We describe three new species of frogs from eastern Thailand based on old and new material. These represent a species of Megophrys from Chantaburi and Sa Kaeo Provinces, a species of Odorrana from Loei Province, and a species of Fejervarya from Ubon Ratchatani Province. Tadpoles are assigned to the new species of Megophrys and Fejervarya and to a recently described species of Rhacophorus from eastern Thailand using molecular identification.

ETYMOLOGY— The specific epithet aureola taken from aureolus (L.) for ornamented with gold, in reference to the diagnostic yellow markings on the limbs and flanks of this species.

DISTRIBUTION AND ECOLOGY— Odorrana aureola is currently known only from Phu Luang Wildlife Sanctuary and Phu Kradueng National Park (Fig. 1) in Loei Province, Thailand. The Phu Luang specimens were collected at night (1915–2030 h) on boulders, rock outcrops and a fallen tree within 4 m of swift, 1–8-m-wide rocky streams near cascades, except FMNH 265922 was collected in the water at the edge of a 2-m-wide stream with slow current between two small dams. Odorrana aureola was collected in sympatry with an apparently undescribed species that morphologically resembles O. chloronota (e.g. FMNH 265931/THNHM 05126, FMNH 265932/THNHM 05127) but that is not the sister taxon of O. chloronota (Stuart et al., 2006).

Bangkok, Thailand, May 24, 2007 — A new species of color-changing frog found in northeastern Thailand sits motionless on the brown soil.

Named the Phu Luang Cliff frog after the national park where it lives, the amphibian, which can grow to 3.5 inches (8.9 centimeters) has a naturally green body that can turn brown.

Scientists have found the rare frog in mountain waterfalls and creeks between 3,280 to 4,291 feet (1,000 to 1,500 meters) above sea level, Tanya Chan-ard, curator of Bangkok's National Science Museum, told the Associated Press.

The frog was discovered a few years ago, although scientists have only recently began studying it, Tanya said. --- http://news.nationalgeographic.com/news/2007/05/photogalleries/wip-week30/photo4.html

Odorrana archotaphus (Inger and Chan-ard, 1997)

Synonym : Rana archotaphus Inger and Chan-ard, 1997

Abstract (1997)

A New species of Rana, superficially resembling Rana livida, has been found in northern Thailand. The new species is like R. livida in having grooves around the discs of the fingers and green color dorsally, and in lacking humeral glands. It is smaller than R. livida and further differs from the latter in having an outer metatarsal tubercle and in lacking sexual dimorphism in the size of the tympanum. It is compared with other species from Southeast Asia that share expanded finger tips, green dorsal coloration, and other characters.

Etymology.- Species name from archon (Gr), meaning ruler, and taphus (Gr), meaning grave. Doi Inthanon is the mountain where the ashes of a former King of Chiang Mai were buried.

ชื่อไทย: งูลายสอลาวเหนือ

ชื่อสามัญ: Angel's Mountain Keelback

ชื่อวิทยาศาสตร์: Paratapinophis praemaxillaris Angel, 1929

ABSTRACT

Paratapinophis praemaxillaris was described by Angel (1929) on the basis of two neonate specimens from Xieng-Khouang in northern Laos. Pope later placed the genus in the synonymy of Opisthotropis Günther, 1872. We collected five adult specimens along the Nan River, in northern Thailand. Here we describe the adults of Angel’s Stream Snake, discuss the

monotypic genus, its distribution, habitat, and diet. Based upon morphology we remove Paratapinophis Angel, 1929 from the synomomy of Opisthotropis. An identification matrix is provided for identifying snakes in the genera Opsithotropis, Parahelicops, and Paratapinophis Bourret, 1934, all have been considered Opisthotropis at one time or another, and we comment on the status of Opisthotropis.

KEY WORDS: Paratapinophis, Opisthotropis, Thailand, China, Laos, stream snakes

FIGURE 4. The microhabitat at the collection included waterfalls (seepage areas),

a gravel and sand bar, and shallow water between the bank and the gravel bar.

FIGURE 2. The map notes the four localities for Paratapinophis praemaxillaris is known from four localities: (1929) the type locality in Xieng-Khouang, Laos; (1981) Doi Saket, Thailand; (1982) Jindong, Yunnan Province, China; and (2007) the Nan River location in Nan Province, Chaloemprakait District, Huia Gon Subdistrict, at the Wang Pian Waterfalls, Thailand.

Figure 2 The adult female holotype (fmnh 213946) of Megophrys lekaguli sp. nov. in preservative. Clockwise from upper left: palmar view of hand; plantar view of foot; lateral view of head; dorsal view; ventral view.

Synonyms

• Megophrys legkaguli Stuart, Chuaynkern, Chan-ard & Inger, 2006

• Xenophrys legkaguli (Stuart, Chuaynkern, Chan-ard & Inger, 2006)

Etymology

The specific epithet is a patronym for Dr. Boonsong Lekagul (1907–1992), biologist and conservationist, in recognition of his contributions to the herpetology of Thailand.

Comparisons

Twelve other species of Megophrys are known to occur within the vicinity of eastern Thailand (Thailand, Myanmar, Cambodia, Laos, and Vietnam): M. aceras (Boulenger, 1903), M. auralensis Ohler, Swan and Daltry, 2002, M. brachykolos Inger and Romer, 1961, M. jingdongensis Fei and Ye in Fei, Ye and Huang, 1983, M. kuatunensis (Pope, 1929), M. longipes (Boulenger, 1885), M. major (Boulenger, 1908), M. minor Stejneger, 1926, M. nasuta (Schlegel, 1858), M. pachyproctus Huang in Huang and Fei, 1981, M. palpebralespinosa Bourret, 1937, and M. parva (Boulenger, 1893).

• Megophrys lekaguli differs from M. brachykolos, M. kuatunensis, M. minor, M. pachyproctus, M. palpebralespinosa, and M. parva by having much larger body size (males with SVL 56.6–66.6 and females with SVL 71.8–94.0 in lekaguli; males < 48, females < 55 in brachykolos, kuatunensis, minor, pachyproctus, palpebralespinosa, and parva).

• Megophrys lekaguli differs from M. aceras, M. longipes, and M. nasuta by lacking a distinct palpebral projection (present in aceras, longipes, and nasuta).

• Megophrys lekaguli differs from M. jingdongensis by having toes with only a rudiment of webbing (toe webbing well developed in jingdongensis) and lacking subarticular tubercles on Fingers I and II (present in jingdongensis).

• Megophrys lekaguli most closely resembles M. auralensis and M. major.

• Megophrys lekaguli differs from M. auralensis by having teeth on vomerine ridges (no teeth on vomerine ridges in auralensis), having males with SVL 56.6–66.6 (males with SVL 71.0–76.9 in auralensis), lacking dermal fringes on toes (present in auralensis), and having Finger II longer than Finger IV (Finger II shorter than Finger IV in auralensis).

• Megophrys lekaguli differs from M. major by lacking dermal fringes on toes (present in major); lacking a light-colored upper lip stripe (present in major); having the narrow, external, vertical face of the upper eyelid dark brown with a light area in its center (uniformly dark brown in major); and having a single row of weakly visible asperities on the underside of the lower jaw (well-developed broad band of asperities in major).

Figure 5 Mouthparts of tadpole (fmnh 266341/thnhm 05391) of Megophrys lekaguli sp. nov. Scale bar = 1 mm.

Distribution and Ecology

Megophrys lekaguli is currently known from Chanthaburi and Sa Kaeo Provinces, Thailand (Fig. 1). Frogs were collected in Sa Kaeo at night (1815–2126 h) on boulders and rock outcrops above a swift, rocky stream with waterfalls in hilly evergreen mixed with bamboo forest and on leaf litter next to a large tree root network 20 m from a swift, rocky stream in disturbed vegetation next to an abandoned road through hilly evergreen forest. Tadpoles were collected at night (2000–2015 h) swimming at the water surface in a 3-m-wide swift, rocky stream in hilly evergreen mixed with bamboo forest and in a shallow stream pool with silt substrate in disturbed vegetation next to an abandoned road through hilly evergreen forest. All five of the Sa Kaeo adult males were calling.

Remarks

The two species that most closely resemble the new species, M. auralensis and M. major, were placed in the genus Xenophrys Günther, 1864 by Khonsue and Thirakhupt (2001; M. major as M. lateralis) and Frost (2004) without supporting argument. Frost et al. (2006) argued for recognition of Xenophrys because their phylogenetic analysis recovered Megophrys as more closely related to Ophryophryne than to Xenophrys. However, their analysis was based only on a single species of Megophrys and Xenophrys, and we feel that this issue remains unresolved. We therefore leave the new species in the genus Megophrys, pending a phylogenetic analysis with improved taxonomic sampling.
