Alsophis portoricensis anegadae (Squamata: Colubridae): morphometric characteristics, activity patterns, and habitat use (original) (raw)

Ahaetulla nasuta anomala (Annandale, 1906) (Squamata: Colubridae), resurrected as a valid species with marked sexual dichromatism

In this paper we resolve the taxonomic confusion related to Ahaetulla nasuta anomala (Annandale, 1906). On the basis of molecular and morphological data, we remove it from the synonymy of Ahaetulla nasuta (Lacépède, 1789) and reinstate it as a valid species—Ahaetulla anomala. This species is sexually dichromatic, males are green and females are brown in colour. Though the brown morph morphologically resembles Ahaetulla pulverulenta (Duméril, Bibron & Du-méril, 1854) there are significant morphological and genetic differences between these two species. Additional information on taxonomy, natural history and distribution of the species is provided.

Discovery of the first male specimen of Tantilla hendersoni Stafford, 2004 (Squamata: Colubridae), from a new locality in central Belize

Tantilla hendersoni Stafford, 2004 was described based on a single female specimen from Cayo District, Belize, and is the only snake species considered to be endemic to the country. We report the discovery of a second specimen, the first male, of Tantilla hendersoni from a new locality in Stann Creek District, and provide a detailed morphological description of the specimen. We also discuss the distribution, conservation, and taxonomic status of the species.

Lycodon odishii, a junior synonym of Lycodon jara, with notes on morphological variation in this species (Squamata, Colubridae)

In this paper we present morphometric data recorded on 11 specimens of Lycodon jara (shaw, 1802) and compare them with those of the recently described species Lycodon odishii Mallik, Parida, Mohanty, Mallik, Purohit, Mohanty, Nanda, sindura, Purohit, Mishra & sahoo, 2014. Multivariate comparison of the two species revealed that variation in L. odishii falls well within the range of the L. jara. Lycodon odishii should, therefore, be treated as a junior synonym of L. jara.

Morphological variation of Ahaetulla prasina (Boie, 1827) (Squamata: Colubridae) in Indonesia, with an expanded description of the species

IOP conference series, 2020

Since Leviton (1967) argued that genus Ahaetulla needed to extensively review, we started to examine the most common Ahaetulla species in Indonesia, A. prasina. This study aims to explain the morphological variation and analyses pattern of A. prasina population from Sumatra, Java, Kalimantan and Sulawesi mainland. This study was carried out by manually counting and measuring the characteristics of 64 A. prasina specimens belongs to Museum Zoologicum Bogoriense (MZB) collections on 2016. All morphological characters have analysed using PCA, homogeneity test and one way anova test. The results shown there have variation in meristic characters as the adaptation pattern due to environmental condition and sexual dimorphism. In contrast, the morphometric characters shown that there no significant and slightly variation within population in these mainlands. Kalimantan population has larger head size than others and assumed as an adaptation towards its prey. This evidence proved that A. prasina is a snake species which successfully adapt in various environment types.

A New species of Coniophanes (Squamata: Colubridae), from the Coast of Michoacán, Mexico

Herpetologica, 2009

We describe a new species of colubrid snake of the genus Coniophanes from the Pacific coast of Michoacán, Mexico. This species is known from a single adult female collected near sea level in dry deciduous forests. The new species is most similar to C. piceivittis, C. schmidti and C. taylori. It shares with these three species 25 scale rows at midbody, a small sub-preocular scale, and a pattern of three dark brown stripes over a pale brown body. The new species differs most noticeably from the other three in possessing a narrower dark vertebral stripe. Coniophanes p. taylori is elevated to a species status, therefore the C. piceivittis group consists of four species.
