NeoBiota 27: 69–79. doi: 10.3897/neobiota.27.5437 Abstract Hemidactylus frenatus is an Asian gecko species that has invaded many tropical regions to become one of the most widespread lizards worldwide. This species has dispersed across the Pacific Ocean to reach Ha- waii and subsequently Mexico and other Central American countries. More recently, it has been reported from northwestern South America. Using 12S and cytb mitochondrial DNA sequences I found that South American and Galápagos haplotypes are identical to those from Hawaii and Papua New Guinea, suggest- ing a common Melanesian origin for both Hawaii and South America. Literature records suggest that H. frenatus arrived in Colombia around the mid-‘90s, dispersed south into Ecuador in less than five years, and arrived in the Galápagos about one decade later.

Individuals moving to new areas usually 18 confront a different set of biotic and abiotic variables, and most dispersed individuals do not 19 survive. However, if they are capable of surviving and adapting to the new conditions, they may 20 establish self-sufficient populations, colonise the new areas, and even spread into nearby 21 locations (Mack et al. 2000). In doing so, they will produce ecological transformations in the 22 new areas, which may lead to changes in other species’ populations and communities, speciation 23 and the formation of new ecosystems (Wilson et al. 2009). 24 25 Human extra-range dispersals since the Pleistocene have produced important distribution 26 changes across species of all taxonomic groups.

  • Geographic Range Extension for the Critically Endangered Leaf-Toed
    Herpetology Notes, volume 10: 499-505 (2017) (published online on 14 September 2017) Geographic range extension for the critically endangered leaf-toed gecko Phyllodactylus sentosus Dixon and Huey, 1970 in Peru, and notes on its natural history and conservation status Pablo J. Venegas¹,²,*, Renzo Pradel¹, Hatzel Ortiz² and Luis Ríos² Abstract. Here we provide the first record of Phyllodactylus sentosus out of Lima city. This new record extends the known species distribution ca. 318 km (straight line) south-southeastern from the southernmost record at Pachacamac, in the city of Lima. This new record also increases the area of occurrence of the species to 1300 km². All specimens were found near or inside crevices surrounded by dry vegetation on a riverbed. We recorded the air and substrate temperature and the relative humidity during the period of activity of the individuals of P. sentosus, which reached its peak between 21:00 and 22:00 hours. We report the presence of the snake, Bothrops pictus, and other potential predators in the area. Moreover, we present a brief morphological description and describe the variation of the collected specimens. Additionally, we report a new record of P. sentosus in the city of Lima. Finally, we discuss on the basis of our new information, about its ecology and conservation status. Keywords.

    The Natural History Journal of Chulalongkorn University 1(1): 1-7, August 2001 ©2001 by Chulalongkorn University Cryptic Taxonomic Diversity in Two Broadly Distributed Lizards of Thailand (Mabuya macularia and Dixonius siamensis) as Revealed by Chromosomal Investigations (Reptilia: Lacertilia) HIDETOSHI OTA1*, TSUTOMU HIKIDA2, JARUJIN NABHITABHATA3 AND SOMSAK PANHA4 1 Tropical Biosphere Research Center, University of the Ryukyus, Nishihara, Okinawa 903-0213, JAPAN 2 Department of Zoology, Graduate School of Science, Kyoto University, Kitashirakawa, Sakyo, Kyoto 606-8502, JAPAN 3 Reference Collection Division, National Science Museum, Klong Luang, Pathumthani 12120, THAILAND 4 Department of Biology, Faculty of Science, Chulalongkorn University, Bangkok 10330, THAILAND ABSTRACT.−Karyological surveys were made for two common lizards, Mabuya macularia and Dixonius siamensis, in Thailand. Of the M. macularia specimens karyotyped, the one from Mae Yom, northwestern Thailand, had 2n=38 chromosomes in a graded series as previously reported for a specimen from southwestern Thailand. The other specimens, all from eastern Thailand, however, invariably exhibited a 2n=34 karyotype consisting of four large, and 13 distinctly smaller chromosome pairs. Of the D. siamensis specimens, on the other hand, those from eastern Thailand invariably exhibited a 2n=40 karyotype, whereas three males and one female from Mae Yom had 2n=42 chromosomes. Distinct chromosomal variation was also observed within the Mae Yom sample that may reflect a ZW sex chromosome system. These results strongly suggest the presence of more than one biological species within each of those “broadly distributed species”. This further argues the necessity of genetic surveys for many other morphologically defined “common species” in Thailand and its vicinity in order to evaluate taxonomic diversity and endemicity of herpetofauna in this region appropriately.

This richness is represented by 35 species of turtles, fve crocodilians, and 437 squamates including three amphisbaenians, 197 lizards, and 237 snakes. Of these, 45 species are endemic to the Galápagos Islands and 111 are mainland endemics. The high rate of species descriptions during recent decades, along with frequent taxonomic changes, has prevented printed checklists and books from maintaining a reasonably updated record of the species of reptiles from Ecuador. Here we present Reptiles del Ecuador (http://bioweb.bio/faunaweb/reptiliaweb), a free, resource-rich online portal with updated information on Ecuadorian reptiles. This interactive portal includes encyclopedic information on all species, multimedia presentations, distribution maps, habitat suitability models, and dynamic PDF guides. We also include an updated checklist with information on distribution, endemism, and conservation status, as well as a photographic guide to the reptiles from Ecuador.

E-mail: [email protected] 3Corresponding author Abstract Morphological and molecular analyses of the Phyllodactylus populations on the Honduran Bay Islands of Guanaja, Roa- tán, and Utila demonstrate that the Guanaja population is best treated as a species distinct from the two other island pop- ulations. Thus, P. palmeus is restricted in distribution to Roatán and Utila islands and the Cayos Cochinos and a new species name is provided for the Guanaja Island population of the P. palmeus species group. Key words: Guanaja Island, Honduras, Phyllodactylus palmeus, Phyllodactylus paralepis sp. nov., morphology, mtDNA, 16S rRNA Introduction Dixon (1968) described the gecko species Phyllodactylus palmeus from a group of 14 specimens collected on Roatán Island and eight others collected on Guanaja Island in the Honduran Bay Islands. Dixon (1968) chose a Roatán specimen as the name bearing holotype of the new species.

  • Phylogenetic Relationships of Geckos of the Genus Nactus and Their Relatives (Squamata: Gekkonidae)
    Acta Herpetologica 3(1): 1-18, 2008 ISSN 1827-9643 (online) © 2008 Firenze University Press Phylogenetic relationships of geckos of the genus Nactus and their relatives (Squamata: Gekkonidae) Todd R. Jackman, Aaron M. Bauer, Eli Greenbaum Department of Biology, Villanova University, 800 Lancaster Ave., Villanova, PA 19085, USA. Corre- sponding author.

We employed nuclear and mitochondrial DNA sequence data to investigate relationships within the gekkonid genus Nactus and between Nactus and other gekkonid genera. Nuclear (RAG-1, PDC) and mitochondrial (ND2) data provide strong support for conflicting patterns of relationship among bisexual New Guinean species of Nac- tus and the unisexual oceanic form N. pelagicus. This may be explained by an ancient mitochondrial introgression event between N. sphaerodactylodes and N. vankampeni, a recent selective sweep of mitochondrial DNA throughout N. vankampeni, and gene conflict stemming from the hybrid event that gave rise to N. pelagicus. Strong support from all data partitions is obtained for the sister group relationship of Nactus to a clade consisting of the Australian Heteronotia and the Southeast Asian Dixonius. Putative synapomorphies of the Nactus/Heteronotia/Dixonius clade include the reduction of the second phalanx of digit IV of the manus and the presence of regular rows of keeled (sometimes multicarinate) dorsal tubercles on the dorsum. Nactus and Heteronotia both include parthenogenetic species formed via hybridogenesis. This is rare among geckos, and vertebrates in general, and at some level may also be synapomorphic. Dixonius is not known to have any all-female species, but “D.
