Anatomical and histological study of the liver and pancreas of two closely related mountain newts Neurergus microspilotus and N. kaiseri (Amphibia: Caudata: Salamandridae)

Anatomical and histological examinations were conducted on the digestive glands of two closely related mountain newts, Neurergus microspilotus (Nesterov, 1916) and Neurergus kaiseri Schmidt, 1952. In N. microspilotus and N. kaiseri the major digestive glands comprise a very large liver and a small pancreas. In both species the liver has two distinct lobes, right and left. Histologically, the pa...

A new newt of the genus Cynops (Caudata: Salamandridae) from Fujian Province, southeastern China

A new species of fire-bellied newt, Cynops fudingensis, is described from northeastern Fujian Province, southeastern China. This species forms a well-supported clade with C. orientalis and C. orphicus based on molecular phylogenetic analysis of nucleotide sequences from mitochondrial DNA subunit two of NADH dehydrogenase and its two flanking tRNAs. Further, its genetic distance to each of the t...

New species of Pachytriton (Caudata: Salamandridae) from the Nanling Mountain Range, southeastern China

New species of amphibians are being reported at an astonishingly fast rate. These include some that have been known to the commercial pet trade for years but have not been formally described due to uncertain origin. The distinctive phenotype of “Pachytriton B” among the Chinese stout newts (also known as paddle-tailed newts) is one such example. Through examination of museum specimens, we locat...

Ontogeny of cranial ossification in the eastern newt, Notophthalmus viridescens (Caudata: Salamandridae), and its relationship to metamorphosis and neoteny.

The ontogenetic sequence of cranial osteogenesis through adulthood is described in samples of newts from completely metamorphosing and partially neotenic populations. Cranial ossification proceeds in the same sequence in both samples. Seven stages of cranial development are described on the basis of conspicuous events that occur during ontogeny. These include four larval stages, metamorphs, eft...
