ABSTRACT This paper presents a revised taxonomy for the living Acrochordidae. The species Acrochordus javanicus Hornstedt, 1787 divided by McDowell in 1979 into two species is further divided, with two new species from south-east Asia formally named for the first time. The taxon A. arafurae McDowell, 1979 is placed in a separate genus, named for the first time. A. granulatus Schneider, 1799 is placed in a separate genus, for which the name Chersydrus Schneider, 1801 is already available. Keywords: Taxonomy; Australasia; Asia; Acrochordus; Chersydrus; new genus; Funkiacrochordus; new tribes; Acrochordidini; Funkiacrochordidini; new subgenus: Vetusacrochordus; new species; malayensis; mahakamiensis.

  • Scale Sensillae of the File Snake (Serpentes: Acrochordidae) and Some Other Aquatic and Burrowing Snakes
    SCALE SENSILLAE OF THE FILE SNAKE (SERPENTES: ACROCHORDIDAE) AND SOME OTHER AQUATIC AND BURROWING SNAKES by DAVID POVEL and JEROEN VAN DER KOOIJ (Section Dynamic Morphology,Institute of Evolutionaryand Ecological Sciences, Leiden University,P.O. Box 9516, 2300 RA Leiden, The Netherlands) ABSTRACT The acrochordid snakes are aquatic, living in environmentswith often a poor visibility. It therefore was investigatedhow these animals detect their prey. Two earlier studies of their scales revealed a rather complex scale organ, composedof hairlike protrusions and plate-like structures. However, no satisfactory explanation was given for the structures found, e.g., an undefined sensilla or a gland. Skin samples from various sites of the body of Acrochordus granulatus and A. javanicus were studied. Scanning electron microscopic pictures revealed that each scale of the head contains up to seven sensillae, and each of the keeled scales of the rest of the body has one. Also a modified Allochrome staining procedure on tissue samples was performed to detect glycogen, which is known to occur in discoidal nerve endings of tactile sense organs of reptiles. Light microscopicslides revealedglycogen particles in a small pillow-shaped area just below the hairlike protrusions of an organ. Moreover, small nerves were recognized near the same location. No indications were found for the scale organs to have a glandular function. Because of the reported reactions of a snake when it is touched by a fish, these scale sensilla are proposed to be very sensitivemechanoreceptors. Comparisons were made with the scale organs of snakes from various habitats, viz. the seasnake Lapemis hardwicki, and burrowing snakes such as Xenopeltis unicolor and Cylindrophisrufus.

Angel Gallardo 470 (1405), Buenos Aires, Argentina Received 23 April 2010; revised 5 April 2011; accepted for publication 18 April 2011 The cranial anatomy of Dinilysia patagonica, a terrestrial snake from the Upper Cretaceous of Argentina, is redescribed and illustrated, based on high-resolution X-ray computed tomography and better preparations made on previously known specimens, including the holotype. Previously unreported characters reinforce the intriguing mosaic nature of the skull of Dinilysia, with a suite of plesiomorphic and apomorphic characters with respect to extant snakes. Newly recognized plesiomorphies are the absence of the medial vertical flange of the nasal, lateral position of the prefrontal, lizard-like contact between vomer and palatine, floor of the recessus scalae tympani formed by the basioccipital, posterolateral corners of the basisphenoid strongly ventrolaterally projected, and absence of a medial parietal pillar separating the telencephalon and mesencephalon, amongst others. We also reinterpreted the structures forming the otic region of Dinilysia, confirming the presence of a crista circumfenes- tralis, which represents an important derived ophidian synapomorphy. Both plesiomorphic and apomorphic traits of Dinilysia are treated in detail and illustrated accordingly. Results of a phylogenetic analysis support a basal position of Dinilysia, as the sister-taxon to all extant snakes.

  • Snakes of the Siwalik Group (Miocene of Pakistan): Systematics and Relationship to Environmental Change
    Palaeontologia Electronica http://palaeo-electronica.org SNAKES OF THE SIWALIK GROUP (MIOCENE OF PAKISTAN): SYSTEMATICS AND RELATIONSHIP TO ENVIRONMENTAL CHANGE Jason J. Head ABSTRACT The lower and middle Siwalik Group of the Potwar Plateau, Pakistan (Miocene, approximately 18 to 3.5 Ma) is a continuous fluvial sequence that preserves a dense fossil record of snakes. The record consists of approximately 1,500 vertebrae derived from surface-collection and screen-washing of bulk matrix. This record represents 12 identifiable taxa and morphotypes, including Python sp., Acrochordus dehmi, Ganso- phis potwarensis gen. et sp. nov., Bungarus sp., Chotaophis padhriensis, gen. et sp. nov., and Sivaophis downsi gen. et sp. nov. The record is dominated by Acrochordus dehmi, a fully-aquatic taxon, but diversity increases among terrestrial and semi-aquatic taxa beginning at approximately 10 Ma, roughly coeval with proxy data indicating the inception of the Asian monsoons and increasing seasonality on the Potwar Plateau. Taxonomic differences between the Siwalik Group and coeval European faunas indi- cate that South Asia was a distinct biogeographic theater from Europe by the middle Miocene. Differences between the Siwalik Group and extant snake faunas indicate sig- nificant environmental changes on the Plateau after the last fossil snake occurrences in the Siwalik section. Jason J.

ABBA1,2 1Faculty of Veterinary Medicine, Universiti Putra Malaysia, UPM Serdang, Selangor Darul Ehsan Malaysia 2Faculty of Veterinary Medicine, University of Maiduguri, P.M.B 1069 Maiduguri, Borno State Nigeria SUMMARY An adult female Elephant Trunk Snake (Acrochordus javanicus) was reported to have been weak and inappetent for five days. The following morning the snake found dead, while in the process of shedding its skin. On post mortem examination, there were multiple circumscribed caseous nodules of various sizes distributed all over the liver, along the respiratory tract and on the lungs. Bacteriological analysis of the lungs and liver swab samples yielded Burkholderia pseudomallei, which was confirmed by PCR amplification of specific 16S rRNA. The condition was diagnosed as melioidosis and the organism was genotypically characterized as sequence type 51, a genotype that has been previously characterized in humans in Malaysia. Antibiotic susceptibility by both Disc diffusion or Kirby Bauer and E-test minimum inhibitory concentration (MIC) showed that the organism exhibited susceptibility to meropenem, imipenem, ceftazidime, cotrimoxazole and co-amoxyclav; the antibiotics recommended in the treatment of melioidosis.

  • A Diverse Snake Fauna from the Early Eocene of Vastan Lignite Mine, Gujarat, India
    A diverse snake fauna from the early Eocene of Vastan Lignite Mine, Gujarat, India JEAN−CLAUDE RAGE, ANNELISE FOLIE, RAJENDRA S. RANA, HUKAM SINGH, KENNETH D. ROSE, and THIERRY SMITH Rage, J.−C., Folie, A., Rana, R.S., Singh, H., Rose, K.D., and Smith, T. 2008. A diverse snake fauna from the early Eocene of Vastan Lignite Mine, Gujarat, India. Acta Palaeontologica Polonica 53 (3): 391–403. The early Eocene (Ypresian) Cambay Formation of Vastan Lignite Mine in Gujarat, western India, has produced a di− verse assemblage of snakes including at least ten species that belong to the Madtsoiidae, Palaeophiidae (Palaeophis and Pterosphenus), Boidae, and several Caenophidia. Within the latter taxon, the Colubroidea are represented by Russel− lophis crassus sp. nov. (Russellophiidae) and by Procerophis sahnii gen. et sp. nov. Thaumastophis missiaeni gen. et sp. nov. is a caenophidian of uncertain family assignment. At least two other forms probably represent new genera and spe− cies, but they are not named; both appear to be related to the Caenophidia. The number of taxa that represent the Colubroidea or at least the Caenophidia, i.e., advanced snakes, is astonishing for the Eocene. This is consistent with the view that Asia played an important part in the early history of these taxa. The fossils come from marine and continental levels; however, no significant difference is evident between faunas from these levels. The fauna from Vastan Mine in− cludes highly aquatic, amphibious, and terrestrial snakes. All are found in the continental levels, including the aquatic palaeophiids, whereas the marine beds yielded only two taxa.

  • THE ORIGIN and EVOLUTION of SNAKE EYES Dissertation
    CONQUERING THE COLD SHUDDER: THE ORIGIN AND EVOLUTION OF SNAKE EYES Dissertation Presented in Partial Fulfillment for the Requirements for the Degree of Doctor of Philosophy in the Graduate School of The Ohio State University By Christopher L. Caprette, B.S., M.S. **** The Ohio State University 2005 Dissertation Committee: Thomas E. Hetherington, Advisor Approved by Jerry F. Downhower David L. Stetson Advisor The graduate program in Evolution, John W. Wenzel Ecology, and Organismal Biology ABSTRACT I investigated the ecological origin and diversity of snakes by examining one complex structure, the eye. First, using light and transmission electron microscopy, I contrasted the anatomy of the eyes of diurnal northern pine snakes and nocturnal brown treesnakes. While brown treesnakes have eyes of similar size for their snout-vent length as northern pine snakes, their lenses are an average of 27% larger (Mann-Whitney U test, p = 0.042). Based upon the differences in the size and position of the lens relative to the retina in these two species, I estimate that the image projected will be smaller and brighter for brown treesnakes. Northern pine snakes have a simplex, all-cone retina, in keeping with a primarily diurnal animal, while brown treesnake retinas have mostly rods with a few, scattered cones. I found microdroplets in the cone ellipsoids of northern pine snakes. In pine snakes, these droplets act as light guides. I also found microdroplets in brown treesnake rods, although these were less densely distributed and their function is unknown. Based upon the density of photoreceptors and neural layers in their retinas, and the predicted image size, brown treesnakes probably have the same visual acuity under nocturnal conditions that northern pine snakes experience under diurnal conditions.
