Abstract: We present a commented taxonomic list of the reptiles found during herpetological surveys carried out in an isolated fragment of tropical dry forest located in the municipality of San Francisco, Zulia state, northwestern Venezuela between January-December 2011. We report a total of 24 species belonging to the order , distributed in 12 families and 21 genera. is the most diverse family with six species, followed by Dipsadidae (four species), ,

Gekkonidae, and with a single species each. The species composition at this site matches what wouldGymnophthalmidae, be expected in Phyllodactylidaea tropical dry forest and in the region. with Our two study species suggests each, that and this finally isolated , tropical dry Iguanidae, forest fragment Elapidae, is the last refuge of the herpetofauna that once occupied much of the dry forests of the northern Maracaibo basin and should therefore be considered for conservation purposes.

Introduction Materials and Methods The tropical dry forests are one of the most threatened Study site ecosystems in (Yepes and Villa 2010). These The study was carried out in a tropical dry forest remnant, approximately 20 Km S of Maracaibo city, soils, due to cattle ranching and agricultural expansion Zulia State, northwestern Venezuela (10°35’17.35” N, (Janzenforests have 1983, suffered Ceballos intense 1995). and In fast Venezuela, modification these of their 71°42’36.15” W, Figure 1). The locality represents an of forests are found in the northern part of the country, isolated forest fragment that originally was a densely mainly in the coastal range, within the central lowlands forested region within the Maracaibo dry forest region. known as Llanos, the Andean cordillera de Merida and the Currently, very small fragmented areas of deciduous dry Lake Maracaibo basin. These forests are the most degraded forests are found west and east of Lake Maracaibo. The and fragmented forest ecosystem in the whole country, forest fragment is approximately 450 ha and is surrounded and only ca. 10% of its original extent remain (Fajardo et by very active anthropogenic activity including croplands, al. 2005). farms, highways, houses and an international airport. Studies on reptiles of the lake Maracaibo basin region mainly consist in inventories carried on in limited composition of this fragment include Tabebuia spp., geographic areas, such as Cienagas de Juan Manuel (Sur CaesalpineaSome of spp the., Pithecellobium species that spp dominate., Pereskia the spp. floral and del Lago), Serranía de Perijá and Península de La Guajira Capparis spp. Nocturnal and diurnal visits to the study site (e.g. Alemán 1953; Pirela et al. 2006; Infante-Rivero 2009), have also indicated the presence of a grey fox population and in descriptions of new species (e.g. Schargel et al.

In recent years, research has mainly focused on the Regarding climatic conditions, evapotranspiration evaluation of the conservation status of some turtles and exceeds precipitation for about 9 months (dry season) crocodilians (e.g. Rivas et al. 2007, Barros et al. 2010).

The common house , Hemidactylus frenatus, is a species introduced to Venezuela (Rivas Fuenmayor et al. 2005, Rivas et al. 2012) and is well adapted to anthropogenic environments. It is often encountered on, or associated to human buildings. Native species of such as G. albogularis, ventralis, and Thecadactylus rapicauda were found in both anthropogenic and natural environments within the study site. as well as boddaerti are scrub and forest species, they are replaced by A. bifrontata and M. pleii, respectively, in more open habitats (Infante-Rivero 2009, the authors pers. obs.). Although there is no record of A. bifrontata in the study area, the species might inhabit adjacent areas outside the forest. The species Norops auratus, Iguana iguana and Boa constrictor were recorded for the area but not collected. We tentatively identify the specimen MBULZ 1189 as Leptodeira bakeri. This species is known only from Aruba Island, Dutch West Indies (Ruthven 1936, Duellman 1958) and on the adjacent Peninsula de Paraguana on mainland Venezuela (Mijares-Urrutia et al. 1995). MBULZ

LIST OF SPECIES Some species that could inhabit the study area but ORDER SQUAMATA , FAMILY IGUANIDAE Oppel, 1811 Ameiva bifrontata Iguana Laurenti, 1768 Drymarchon caudomaculatus, Leptophis were not observed in our survey are: Iguana iguana (Linnaeus, 1758) occidentalis, Mabuya zuliae and Liotyphlops albirostris. It FAMILY DACTYLOIDAE Fitzinger, 1843 should be noted that another species of Drymarchon, D. Genus Norops Wagler, 1830 melanurus, was recorded from Palmar River by Lancini Norops auratus Daudin, 1802 (1962) but not found at our study site. According to FAMILY SPHAERODACTYLIDAE Underwood, 1954 Lancini (1962), the single specimen collected by him had Genus Gonatodes Fitzinger, 1843 a whitish head and a dark brown, almost black, body. This Gonatodes albogularis (Duméril and Bibron, 1836) description corresponds better to the description of the FAMILY GEKKONIDAE Gray, 1825 recently described D. caudomaculatus, a taxon restricted Genus Hemidactylus Gray, 1825 to the lowlands of northwestern Venezuela and adjacent Hemidactylus frenatus Schlegel, 1836 Colombia (Peninsula de la Guajira) (Wüster et al. 2005, FAMILY PHYLLODACTYLIDAE Gamble, Bauer, Greenbaum and Mendoza and Fernandez Lucero 2009). Wüster et al. Jackman, 2008 (2005) mention that the lack of any obvious change of Genus Phyllodactylus Gray, 1828 hue along the dorsal side of the body differentiates D. Phyllodactylus ventralis O’Shaughnessy, 1875 caudomaculatus from D. melanurus. Additionally, the Genus Thecadactylus Oken, 1817 locality is more appropriate to D. caudomaculatus than to Thecadactylus rapicauda (Houttuyn, 1782) D. melanurus, which is a species that inhabits premontane FAMILY GYMNOPHTHALMIDAE Merrem, 1820 forest. This is also supported by the collection of two Genus Gymnophthalmus Merrem, 1820 Gymnophthalmus speciosus (Hallowell, 1861) (MBLUZ 1171) and at km 106 on the road Maracaibo- Genus Tretioscincus Cope, 1862 Machiquesadditional specimens (MBLUZ 987) on the located road Elat Molinete-Carrasquero80 km N and 100 km Tretioscincus bifasciatus Shreve, 1947 S respectively from the study site. Infante-Rivero et al. FAMILY TEIIDAE Gray, 1827 (2005) also extend to 100 km SW of JBM. We conclude that Genus Ameiva Meyer, 1795 D. melanurus by Lancini (1962) Ameiva praesignis Cope, 1862 is very probably a D. caudomaculatus.
