[Herpetology • 2000] Naja mandalayensis • A New Cobra (Elapidae: Naja) from central Myanmar (Burma)


Naja mandalayensis  
Slowinski & Wüster, 2000


We describe a new species of spitting cobra of the genus Naja from central Myanmar. Multivariate analyses of morphological characters and analyses of mtDNA sequences confirm the distinctiveness of the new species. Phylogenetic analysis of the mtDNA data indicate that among the cobra species of the southeast Asian mainland, the new species is most closely related to the Thai spitting cobra, Naja siamensis. The new species is apparently endemic to an arid region in central Myanmar.

[Herpetology • 2016] Redescription and Range Extension of Microhyla sholigari Dutta & Ray (Anura: Microhylidae) from South West India


male  Microhyla sholigari from Bisle


Abstract

Microhyla sholigari is an endangered frog described in the year 2000. The original description was based on non-adult types and lacked information on several morphological characters, call structure, genetic material and photographs of the animal in life. The absence of such information posed challenges in field identification of this species. Since the original description, there is one other reported sighting of this species from Kerala in 2001. We encountered specimens that we confer to this species based on morphological similarity to the subadult holotype, from several new localities within and outside the Western Ghats of Karnataka. We here redescribe the species based on additional adult vouchers, provide molecular data, describe the advertisement call and report a range extension. Based on its current distribution, we assess the threat status of the species and suggest listing it as Least Concern according to IUCN Red List criteria. Our paper bridges an important gap in the knowledge of the genus Microhyla in India and highlights the importance of systematic surveys in documenting and understanding amphibian diversity in the region.

[PaleoMammalogy • 2016] A New Skull of the Fossil Porpoise Numataphocoena yamashitai (Cetacea: Phocoenidae) from the upper part of the Horokaoshirarika Formation (lower Pliocene), Numata Town, Hokkaido, Japan, and Its Phylogenetic Position

ABSTRACT

An early Pliocene porpoise, Numataphocoena yamashitai from Hokkaido, Japan, is known from the holotype, a fairly well-preserved skeleton with an incomplete skull and a referred earbone. A new skull referred to Numataphocoena yamashitai found from almost the same locality as the holotype is interesting because it expands knowledge of skull morphology and improves the diagnosis of this taxon. Numataphocoena yamashitai differs from other phocoenids in having the characteristic feature in the maxilla associated with the posterior dorsal infraorbital foramen, narrower and sharper anterior part of the internal acoustic meatus, and a robust anterior process of the periotic. A new cladistic analysis places Numataphocoena yamashitai adjacent to Haborophocoena toyoshimai and Haborophocoena minutus, among a clade of early branching phocoenids, all of which are chronologically and geographically close to each other. The new skull is probably a younger individual because it is about 80% the size of that of the holotype and it shows closed but unfused sutures. Our description of this specimen helps to understand the intraspecies variation of the extinct species Numataphocoena yamashitai.

Key words: skull; Phocoenidae; phylogeny; maxillary terrace; ontogeny; intraspecies variation

CONCLUSION: 
The new referred skull (NFL 2074) of Numataphocoena yamashitai from the upper part of the Horokaoshirarika Formation (early Pliocene), Numata, Hokkaido, Japan, adds diagnostic characters of the species, recognizes variations among the species and reveals the phylogenetic position among the Phocoenidae. Our cladistic analysis places Numataphocoena yamashitai adjacent to Haborophocoena toyoshimai and Haborophocoena minutus, among a clade of early branching phocoenids, all of which are chronologically and geographically close to each other, being all from Hokkaido. Numataphocoena yamashitai differs from other phocoenids in having a maxillary terrace, narrower and sharper anterior part of the internal acoustic meatus, and a robust anterior process of the periotic. NFL 2074, which is about 80% size of the holotype, NFL 7, is probably younger than the physically mature holotype. NFL 2074 does not have a well-developed nuchal crest like the holotype skull, which is probably the result of intraspecific variation.

Abstract
A new periotic of Numataphocoena yamashitai from the upper part of the Horokaoshirarika Formation (lower Pliocene), Numata, Hokkaido, Japan shows younger ontogenetic features in comparison to the matured holotype (NFL 7). The referred specimen of N. yamashitai is smaller (approximately 90% in size) than the physically and sexually matured holotype periotic. The holotype (NFL 7) and referred specimen (NFL 2617) show several differences owing to ontogenetic changes, such as: the holotype (NFL 7) has a more strongly swollen medial part of the anterior process, blunt anterior keel, rounded anterodorsal angle, deeper and clearer anterior incisure, more rounded pars cochlearis, deeper and narrower hiatus epitympanicus rather than a flat area, longer posterior process with an extra edge posterolaterally. N. yamashitai differs from other fossil phocoenids in having a narrower and sharper anterior part of the internal acoustic meatus and a robust anterior process. Haborophocoena toyoshimai similarly has a relatively narrow internal acoustic meatus and a robust anterior process, compared with other fossil phocoenids. Between N. yamashitai and H. toyoshimai, N. yamashitai has a narrower internal acoustic meatus and a more robust anterior process. These similarities imply a close relationship between Numataphocoena and Haborophocoena. The new specimen provides diagnostic features and insight into ontogenetic variation of N. yamashitai.

FIGURE 5 –  Tocantinia stigmovittata Büneker, R. Bastian & C. Costa in habitat.

ABSTRACT
A synopsis of the genus Tocantinia is provided, with two new species being described and illustrated: Tocantinia dutilhiana and Tocantinia stigmovittata. Descriptions, illustrations and data on etymology, ecology, conservation status, distribution and habitat of the species are provided. The taxonomic placement of the genus in morphological and phylogenetic aspects is discussed.

Keywords: Taxonomy, Tocantinia mira, Tocantinia dutilhiana sp. nov., Tocantinia stigmovittata sp. nov., Cerrado Biome


TAXONOMY
Tocantinia Ravenna, Onira, v. 5, n. 3, p. 9, 2000.
Type: Tocantinia mira Ravenna

Etymology: The genus name refers to Tocantins (Latinized Tocantinia), a Brazilian state where the type population of the species of the genus is located.

Distribution and habitat: The genus is found in relatively large populations as geophytes in chemically poor, shallow and sandy soils from the Cerrado Biome. It is an endemic genus of Brazil, with populations known from central Brazil in the southeast of the state of Tocantins; in the central and southern-central part of Espinhaço Mountain Range; in the central region of Minas Gerais state; and in southwestwern Bahia state.


1. Tocantinia mira Ravenna, Onira, v. 5, n. 3, p. 10, 2000, (Fig. 1A-B).

Etymology: The specific epithet of the species, “mira” (Latin mira wonderful) possibly refers to morphological uniqueness of the species at the time it was described.

 Distribution: Species known only by the type collection, whose specimens are from a collection of a natural population at the locality in Rio Lajes, in the city of Paranã, southeastem of the Tocantins state (Brazil). The original population of the collection was not located, as well as subsequent collections of this species.

[Paleontology • 2000] Nanolania anatopretia • A new tiny rhytidosteid (Temnospondyli: Stereospondyli) from the Early Triassic of Australia and the possibility of hidden temnospondyl diversity


 Life restoration of Nanolania anatopretia.

A new genus and species of stereospondyl temnospondyl, Nanolcmia anatopretia, is described from the Early Triassic Arcadia Formation (Rewan Group) of Queensland, Australia. N. anatopretia has several character states that suggest it belongs to the group of derived trematosaurian stereospondyls that include the Rhytidosteidae and Brachyopoidea. These include the absence of a lacrimai, an untwisted quadrate ramus of the pterygoid, and a shallow otic notch. It is tentatively referred to the Rhytidosteidae. N. anatopretia is the third temnospondyl taxon from the Arcadia Formation to be represented by a skull less than 50 mm long. The others are the basal stereospondyl Lapillopsis nana, and juveniles of the capitosaurid Parotosuchus aliciae. Given that Lapillopsis nana and Nanolania anatopretia are not known from any larger specimens, and that the temnospondyl fauna from the Arcadia Formation has been well sampled, it is suggested that they are species that never grew large. It seems quite likely that a diverse array of small temnospondyls lived alongside the larger temnospondyls of the Triassic elsewhere in the world but have not been discovered due to biases working against the preservation and collection of small temnospondyl specimens.

[Herpetology • 2000] Triceratolepidophis sieversorum • A New Genus and Species of Pitviper (Serpentes: Viperidae: Crotalinae) from Vietnam


Triceratolepidophis sieversorum  
Ziegler, Herrmann, David, Orlov & Pauwels, 2000
Abstract
A new genus and species of pitviper from the Annam Mountain Range, Quang Binh Province, Vietnam are described. The description is based on a single male specimen. This member of the Trimeresurus group is characterized by the presence of raised horn-like multiple supraoculars and by having the unique structure of the dorsal scales showing a keel consisting of three horn-like upraisings as well as the unique microdermatoglyphic pattern of the Oberhäutchen, which is tessellate fimbriate. First notes on its biology are provided and possible relationships of this new and striking taxon are discussed.

Abstract
A new species of green, prehensile-tailed pitviper of the genus Bothriechis is described from the Atlantic slopes of eastern Guatemala and western Honduras. This species appears to be most closely related to B. bicolor of the Pacific versant of Chiapas (Mexico) and Guatemala. Several other species of Bothriechis occur on the Atlantic versant of northern Central America, including two montane species, B. aurifer and B. marchi but, with one possible exception, these are not known to be sympatric with the new species and occur in different mountain ranges. The widespread B. schlegelii occurs up to at least 900 m on the Sierra de Caral, where the lowest elevation recorded for the new species is 885 m.
Key words: Reptilia, Squamata, Viperidae, Pitvipers, Bothriechis, New species, Izabal, Guatemala, Honduras.



Etymology.– The specific epithet is derived from the Greek thalassinos, meaning blue-green, in allusion to the striking coloration of this snake.
Habitat, distributon, and habits.– In Guatemala, this species occurs in Lower Montane Wet Forest (sensu Holdridge 1959) at elevations of 885-1 450 m. In Honduras, it has been recorded to occur also in Lower Montane Moist Forest (Meyer and Wilson 1985) and up to 1 730 m in the mountains east of Nueva Ocotepeque (LSU 23821).

Abstract
The distribution of a new species of striped rabbit Nesolagus timminsi Averianov, Abramov et Tikhonov, 2000 is restricted to the central part of the Annamite Mountains, along the border between Vietnam and Laos. A low density of separated populations and hunting pressure in Vietnam already makes this species critically endangered.

Key words: striped rabbit, Nesolagus timminsi, Vietnam

[Herpetology • 2000] A Redescription of Atheris squamigera (Hallowell, 1854) • widespread species of Central Africa



Abastract
We provide a redescription of the holotype of Atheris squamigera (Hallowell), which previously was reported as lost We show that characters used to differentiate A. anisolepis Mocquard are either present in the holotype of A. squamigera (a male), or are sexually dimorphic traits found in female A. squamigera. We consider A. anisolepis to be a junior synonym of A. squamigera.
