Submit it to the SWCHR Bulletin for possible publication. Submitted manuscripts from SWCHR members, as well as non- members, will be considered. To be accepted for publication, submissions must deal with herpetological species native to the American Southwest. Such topics as field notes, county checklists, range extensions, taxonomy, reproduction and breeding, diseases, snake bite and venom research, captive breeding and maintenance, conservation issues, legal issues, etc. are all acceptable. For assistance with formatting manuscripts, search ‘scientific journal article format’ on the internet and tailor the resultant guidance to suit. Previously published articles or papers are acceptable, provided you still hold the copyright to the work and have the right to re-publish it. If we accept your paper or article for publication, you will still continue to be the copyright holder. If your submission has been previously published, please provide the name of the publication in which it appeared along with the date of publication. All submissions should be manually proofed in addition to being spell checked and should be submitted by email as either Microsoft Word or text documents. Send submissions to [email protected]. SWCHR Bulletin 28 Fall 2014 A Message from the President It is fall again, which means “back to school” for many people, of all ages—and on that subject, I would like to remind everyone that we are sending the SWCHR Bulletin to various universities, and it can be easily accessed by the students and faculty of these institutions. I would also like to speak to any students of these universities who may be reading this, and let you know that we are always looking for articles, papers, and natural history notes—you don’t have to be a member to submit and have your work published here. Though the SWCHR Bulletin is not currently a peer-reviewed publication, it fills a needed niche as a good home for amateur works (as well as those of degreed biologists) which may inspire further research. Although you do not have to be a member to submit articles or papers, we hope that you will have a look around the website, check out our other Bulletin issues, and consider joining us a member—Student (under 18) and Collegiate (any age) memberships are available at discounted rates. In this issue of the Bulletin, we have some very interesting observations and articles to offer. Tom Lott offers some comments about the recent proposed revision of the Lampropeltis triangulum complex. Our editor, Chris McMartin, details his experiences with escapes of captive specimens of two species of Coleonyx. Mike Pingleton gives us his account of the recent NAFHA meet in eastern Arizona and western New Mexico, which several SWCHR members attended. Terry Cox tells us about a Crotalus atrox residing on his property in southern Arizona, and its interesting choice of refuge. Robert Twombley reviews The Invisible Ark by Dave and Tracy Barker. Hannah Strauss gives a nice account of being onsite naturalist at the Desert Tortoise Research natural Area. David Kneer notes an interesting field observation of a Coachwhip preying on a Copperhead. Much of the southwest has recently been experiencing excess precipitation, and hopefully this will work to the good for the herpetofauna and other wildlife of the region. This is often the time of year during which I see the most herps of the year here in south Texas—this being the wettest part of the year, on average, in this area. I often think of the fall as “rat snake season”, as I usually see lots of our two species of Pantherophis out and about during daylight, as temps begin to cool down. I hope it is a great fall season for herps all across the southwest! SWCHR Bulletin 29 Fall 2014 Highlights from the NAFHA 2014 If NAFHA meetings and field trips were simply about padding Field Meeting one’s life list and other selfish pleasures, there would be little point in writing up reports like this one.

The occasion was the annual field obtaining scientific permits from Arizona and New Mexico that meeting of the North American Field Herping Association covered data collection activities for the assembled group.

The meeting location changes each year; the 2012 permits allowed attendees to detain animals for photographs, meeting was held at the famous “Snake Road” in southern and to record localities and physical data, before releasing the Illinois, and in 2013, the coastal pine forests of North Carolina herps at their point of capture. Arizona herps found “Dead On played host. It was time for a swing out west, so this year the Road” (DOR) were handed in to Dave Weber, who turned them meeting was held on the eastern slope of the Chiricahua over to the fish and game folks. In the first two weeks since the Mountains, with activities centering around Portal, Arizona, and meeting ended, several hundred data records have been entered nearby Rodeo, New Mexico. Many of the attendees booked in the Herp Education and Research Project (www.naherp.com) rooms in the lodge at Portal, or camped nearby in the ‘Cheery and HerpMapper (www.herpmapper.org) databases, with more Cows,’ as the mountains are sometimes called.

A three-way division of the New World Genus Lampropeltis Fitzinger, 1843 (Serpentes:Colubridae). Raymond T. Hoser 488 Park Road, Park Orchards, Victoria, 3114, Australia. Phone: +61 3 9812 3322 Fax: 9812 3355 E-mail: [email protected] Received 15 March 2012, Accepted 2 April 2012, Published 30 April 2012. ABSTRACT The King and Milk Snakes, Lampropeltis Fitzinger, 1843 are familiar to most American herpetologists. Notwithstanding their familiarity and general abundance. the taxonomy of the genus has remained unstable to the present time. Confusion and dispute remains in terms of the exact number of species. Even the generic placement of members has been unstable in recent years. In 2009, Pyron and Burbink placed the short-tailed snake, known widely as Stilosoma extenuatum within the synonymy of Lampropeltis. Other available genus names for subgroups and species groups have generally not been used. Most recently the detailed evidence published by Pyron et. al. (2011) led the authors to note that they viewed the genus Lampropeltis to be paraphyletic at the genus level as currently defined. Viewing this evidence and the obvious morphological and behavioral differences between the species groups, this paper divides the genus as currently accepted in three ways. Lampropeltis retains the type species getula and several others, including Stilosoma which remains subsumed as does Ophibolus Baird and Girard, 1853. Oreophis Dugès, 1897 is resurrected to contain the type species mexicana and several others. Finally the divergent taxon, calligaster is placed within its own monotypic genus Eksteinus gen.

  • MOLECULAR SYSTEMATICS and PHYLOGENY of OLD and NEW WORLD RATSNAKES, Elaphe AUCT., and RELATED GENERA (REPTILIA, SQUAMATA, COLUBRIDAE)
    Russian Journal of Herpetology Vol. 9, No. 2, 2002, pp. 105 – 124 MOLECULAR SYSTEMATICS AND PHYLOGENY OF OLD AND NEW WORLD RATSNAKES, Elaphe AUCT., AND RELATED GENERA (REPTILIA, SQUAMATA, COLUBRIDAE) Urs Utiger,1,5 Notker Helfenberger,2 Beat Schätti,3 Catherine Schmidt,1 Markus Ruf,4 and Vincent Ziswiler1 Submitted January 30, 2002. The phylogenetic relationships of the Holarctic ratsnakes (Elaphe auct.) are inferred from portions of two mitochondrial genes, 12S rRNA and COI. Elaphe Fitzinger is made up of ten Palaearctic species. Natrix longissima Laurenti (type species) and four western Palaearctic species (hohenackeri, lineatus, persicus, and situla) are assigned to Zamenis Wagler. Its phylogenetic affinities with closely related genera, Coro- nella and Oocatochus, remain unclear. The East Asian Coluber porphyraceus Cantor is referred to a new genus. This taxon and the western European Rhinechis scalaris have an isolated position among Old World ratsnakes. Another new genus is described for four Oriental species (cantoris, hodgsonii, moellen- dorffi, and taeniurus). New World ratsnakes and allied genera are monophyletic. Coluber flavirufus Cope is referred to Pseudelaphe Mertens and Rosenberg. Pantherophis Fitzinger is revalidated for Coluber gut- tatus L. (type species) and further Nearctic species (bairdi, obsoletus, and vulpinus). Senticolis triaspis is the sister taxon of New World ratsnakes including the genera Arizona, Bogertophis, Lampropeltis, Pitu- ophis, and Rhinocheilus. The East Asian Coluber conspicillatus Boie and Coluber mandarinus Cantor form a monophyletic outgroup with respect to other Holarctic ratsnake genera and are referred to Euprepiophis Fitzinger. Three Old World species, viz. Elaphe (sensu lato) bella, E. (s.l.) frenata, and E. (s.l.) prasina remain unassigned.

With a phylogeny containing all known families and subfamilies, we find that these patterns cannot be explained by background rates of speciation and extinction. The majority of diversity appears to derive from a radiation within the superfamily Colubroidea, potentially stemming from the colonization of new areas and the evolution of advanced venom-delivery systems. In contrast, negative relationships between clade age, clade size, and diversification rate suggest the potential for possible bias in estimated diversification rates, interpreted by some recent authors as support for ecologically mediated limits on diversity. However, evidence from the fossil record indicates that numerous lineages were far more diverse in the past, and that extinction has had an important impact on extant diversity patterns.
