Ambatoloaka is a small resort, located on the south-western coast of the island. When you arrive in After the discovery of a new species of day gecko (Phelsuma Ambatoloaka, with the knowledge that it is Madagascar’s biggest vanheygeni) by Exo Terra Manager Emmanuel Van Heygen in tourist centre, you realize that Madagascar still has a long way 2004 during the Exo Terra Expedition Madagascar 2004, many to go to before it will make it into the mainstream travel questions were left unanswered regarding the distribution range, brochures. behaviour and ecology of this remarkable discovery. In order to find answers to these questions the Exo Terra team returned to We checked in into our hotel for our last night of luxury. Most the area in June 2006. people would already consider staying in this hotel adventurous. It did not take long before we spotted our first day gecko, living on the ceiling of one of the rooms.

Ampopo The Ankify Peninsula is situated in the Sambirano Delta and probably the terra typica of the day gecko Phelsuma klemmeri. Upon arrival we immediately organized a vehicle to bring us as close as possible to the bamboo forests in the peninsula’s interior. This would be the last car we would see for a while.

Also the Phelsuma vanheygeni seems to be very common in this area but is a bit more difficult to Bezavona spot since it lives more between the bamboo leaves and thinner branches. One bamboo is usually the territory of a pair. During the day they move through the denser upper part of the bamboo and venture only seldom onto the thicker stem. They probably sleep in the dense leaves during the night. We also scanned the forests near the campsite for chameleons. The first one we encountered was a massive Furcifer oustaleti. It is abundant and widespread in Madagascar and inhabits both warm and humid coastal lowlands but seems to prefer drier forests.

    Extreme Miniaturization of a New Amniote Vertebrate and Insights Into the Evolution of Genital Size in Chameleons

    www.nature.com/scientificreports OPEN Extreme miniaturization of a new amniote vertebrate and insights into the evolution of genital size in chameleons Frank Glaw1*, Jörn Köhler2, Oliver Hawlitschek3, Fanomezana M. Ratsoavina4, Andolalao Rakotoarison4, Mark D. Scherz5 & Miguel Vences6 Evolutionary reduction of adult body size (miniaturization) has profound consequences for organismal biology and is an important subject of evolutionary research. Based on two individuals we describe a new, extremely miniaturized chameleon, which may be the world’s smallest reptile species. The male holotype of Brookesia nana sp. nov. has a snout–vent length of 13.5 mm (total length 21.6 mm) and has large, apparently fully developed hemipenes, making it apparently the smallest mature male amniote ever recorded. The female paratype measures 19.2 mm snout–vent length (total length 28.9 mm) and a micro-CT scan revealed developing eggs in the body cavity, likewise indicating sexual maturity. The new chameleon is only known from a degraded montane rainforest in northern Madagascar and might be threatened by extinction. Molecular phylogenetic analyses place it as sister to B. karchei, the largest species in the clade of miniaturized Brookesia species, for which we resurrect Evoluticauda Angel, 1942 as subgenus name. The genetic divergence of B. nana sp. nov. is rather strong (9.9‒14.9% to all other Evoluticauda species in the 16S rRNA gene). A comparative study of genital length in Malagasy chameleons revealed a tendency for the smallest chameleons to have the relatively largest hemipenes, which might be a consequence of a reversed sexual size dimorphism with males substantially smaller than females in the smallest species.

The giant day gecko Phelsuma grandis, endemic to Madagascar, was introduced to Reunion Island (Indian Ocean) in the mid-1990s. No studies have been conducted so far to define its precise distribution and habitat. To fill the knowledge gap about this invasive species, we compiled available data and performed field work during 2007-2014. We detected 13 distinct populations of P. grandis, occurring mainly in the northern part of Reunion Island and on the west coast. This gecko inhabits human disturbed areas (gardens, urban parks, bamboos, orchards, coconuts, and banana plantation) and secondary habitats (shrubby savanna, and secondary dry woodlands, secondary dry and wet thickets). Its distribution strongly suggests that saltatory dispersal (through deliberate and/or accidental transport) and natural colonization are the mechanisms of spreading through Reunion Island. All our data in combination with both P. grandis ecology and native environmental range suggested that this gecko may colonize native forest, and constitutes a potential important threat to the native biodiversity of Reunion Island (arthropods and lizards).

    The Gold Dust Or Flat Tailed Day Gecko)

    British Herpetological Society Bulletin, No. 57, 1996 NOTES ON KEEPING AND BREEDING PHELSUMA LATICAUDA (THE GOLD DUST OR FLAT TAILED DAY GECKO) RICHARD HARLING 38 Twin Oaks Close, Broadstone, Dorset, BH18 8JF INTRODUCTION Gold Dust Geckoes are from the Comoros islands off Madagascar, as well as being introduced to other places including Madagascar itself. They are tropical lizards with an insectivorous diet, supplemented by fruit. During Easter 1995, I obtained three day geckos from a reptile shop in London. I wanted two females and a male but was unfortunately sent two males and a female - this I suspected quite quickly as the fully grown male would not tolerate one of the "females". "She" has now grown and become as big as him, has obvious femoral pores (always much more obvious that on the female) and is definitely a "him". It is generally recommended that captive-bred reptiles are best as they are tamer and more accustomed to captivity. DESCRIPTION In good light they are like living jewels. They have two horizontal bright red stripes across the top of their fairly blunt snouts up to their beautiful blue almost eye-shadowed eyes which do not have eyelids and are licked clean by their long pink tongue. There is often another red bar just behind the eyes. The posterior dorsal surface of the head and anterior half of the back is powdered with a yellowy-gold. Briefly the back is just green and then there are three bright red, "tear drops" which break up posteriorly into numerous small red spots which spread down the yellowy tail with a hint of green.

It occurs in disturbed and secondary vegetation, including in towns, and can reportedly be locally abundant, although no quantitative measures of population size are available. Plausible estimates indicate that populations may be in the range of tens of thousands to hundreds of thousands. The species is exported as a live animal for the pet trade. Recorded exports from the Comoros began in 2000 and, between then and 2003, some 7,000 animals were recorded as exported, latterly almost all to the USA. Only 300 were recorded in trade in 2003, and none in 2004 (or, to date, in 2005), despite the fact that exports of other Comorean reptiles, which dropped to a low or zero level in 2003, began again in 2004. Captive breeding has taken place, in the USA at least. The species is not known to be covered by any national legislation.

It is currently known from only four museum specimens and has not been reliably seen in the wild since 1994, despite recent attempts to find it at the type locality. Here we report the rediscovery of P. masohoala at Marojejy National Park, and review all known records of this species. Our observations provide important new data on the ecology, distribution, and behavior of this rare species, which appears to be difficult to detect due to its cryptic coloration and arboreal habits. Key Words.—conservation; distribution; Gekkonidae; Marojejy Introduction type locality, from the Tamatave area. However, doubts about the locality of this specimen have been considered Phelsuma masohoala (Raxworthy and Nussbaum sufficiently serious that it was not included in the IUCN 1994) is one of the least known species of gecko in the Red List species account (Glaw and Rakotondrazafy world. It is distinguished by its grey, black and white 2011). Photographs of this specimen in life appear in coloration; all other Phelsuma known to be sympatric Meier and Böhme (1996), Glaw and Vences (2007), and with it are primarily green.

    Eine neue Taggecko-Art der Gattung Phelsuma aus Ost-Madagaskar Eine neue Taggecko-Art der Gattung Phelsuma aus Ost-Madagaskar (Reptilia: Squamata: Gekkonidae) PATRICK SCHÖNECKER, STEFANIE BACH & FRANK GLAW Zusammenfassung Wir beschreiben eine neue Phelsuma-Art, welche die kleinste bekannte Art der Gattung darstellt. Verwandtschaftlich steht sie vermutlich der Phelsuma lineata-Gruppe nahe. Das bisher bekannte Vorkommen beschränkt sich auf eine Region in der Umgebung von Manambato an der zentralen Ostküste Madagaskars. Schlüsselwörter: Sauria: Gekkonidae: Phelsuma; neue Art; Madagaskar. 1 Einleitung Bei der Gattung Phelsuma handelt es sich um eine artenreiche Gruppe von Taggeckos. Sie umfasst derzeit 39 Arten, die hauptsächlich auf Madagaskar und weiteren Inseln im westlichen Indischen Ozean verbreitet sind. Die Grundfarbe der Tiere setzt sich meistens aus diversen Grün- und Brauntönen zusammen, kann jedoch auch graue, gelbe, blaue, schwarze und weiße Elemente enthalten. Die Gesamtlänge der größten rezenten Arten (P. madagascariensis grandis GRAY, 1870 und P. guentheri BOULENGER, 1885) kann bis zu 300 mm betragen, wobei die bereits ausgestorbene P. gigas von der Insel Rodrigues noch erheblich größer wurde (HALLMANN et al. 1997). Die bisher kleinsten Vertreter sind P. quadriocellata parva MEIER, 1983 und P. pusilla pusilla MERTENS, 1964, die beide eine maximale Gesamtlänge von 85 mm erreichen (MERTENS 1964, HALLMANN et al. 1997). Im Jahr 2000 gelangte ein größerer Import mit madagassischen Reptilien und Amphibien nach Deutschland. Dieser enthielt unter anderem auch einige Unterarten von Phelsuma lineata (GRAY, 1842), nämlich P. l. bombetokensis MERTENS, 1964, P. l. dorsivittata MERTENS, 1964 und P. l. lineata (GRAY, 1842). Als sogenannter „Beifang“ fanden sich darunter drei auffallend kleine tagaktive Geckos.
