“…In contrast, within draconine agamids (Figure 16), many intergeneric relationships are weakly supported, and some genera are non-monophyletic (Figure 16; see also [142]), including Gonocephalus ( G. robinsonii is only distantly related to other Gonocephalus ) and Japalura (with species distributed among three distantly related clades, including one allied with Ptyctolaemus , another with G. robinsonii, and a third with Pseudocalotes ).…”

A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes

BackgroundThe extant squamates (>9400 known species of lizards and snakes) are one of the most diverse and conspicuous radiations of terrestrial vertebrates, but no studies have attempted to reconstruct a phylogeny for the group with large-scale taxon sampling. Such an estimate is invaluable for comparative evolutionary studies, and to address their classification. Here, we present the first large-scale phylogenetic estimate for Squamata.ResultsThe estimated phylogeny contains 4161 species, representing all currently recognized families and subfamilies. The analysis is based on up to 12896 base pairs of sequence data per species (average = 2497 bp) from 12 genes, including seven nuclear loci (BDNF, c-mos, NT3, PDC, R35, RAG-1, and RAG-2), and five mitochondrial genes (12S, 16S, cytochrome b, ND2, and ND4). The tree provides important confirmation for recent estimates of higher-level squamate phylogeny based on molecular data (but with more limited taxon sampling), estimates that are very different from previous morphology-based hypotheses. The tree also includes many relationships that differ from previous molecular estimates and many that differ from traditional taxonomy.ConclusionsWe present a new large-scale phylogeny of squamate reptiles that should be a valuable resource for future comparative studies. We also present a revised classification of squamates at the family and subfamily level to bring the taxonomy more in line with the new phylogenetic hypothesis. This classification includes new, resurrected, and modified subfamilies within gymnophthalmid and scincid lizards, and boid, colubrid, and lamprophiid snakes.

“…Within this group, the 20 microchromosome state is shared only with Bronchocela cristatella (see Solleder and Schmid [1988] and below), Calotes versi-color in one report (see below), and Gonocephalus robinsonii (see Diong et al, 2000). In contrast, this state is common in the clade consisting of groups II-IV of Moody (1980) (see Honda et al [2000Honda et al [ , 2002 and Macey et al [2000: as the Australian-New Guinean clade]) as pointed out by Witten (1983). Diong et al (2000), recognizing the common occurrence of 20 microchromosomes in G. robinsonii and some Australian-New Guinean species, surmised that G. robnsonii might have been derived from endemic Australian radiation, followed by long dispersals like Physignathus cocincinus (Honda et al, 2000).…”

“…A total of 16 specimens representing four species, Acanthosaura armata, Bronchocella cristatela, Calotes emma, and C. versicolor, were karyotyped (Table 1). All of these species belong to group V of the Agamidae sensu Moody (1980) (see Honda et al [2000Honda et al [ , 2002 and Macey et al [2000: as the South Asian Glade] for the monophyly of this group).…”

“…Chromosomal approaches to phylogeny have been receiving persistent, formidable criticism chiefly on the ground of adequacy in analytical procedures adopted and in presumptions regarding the mode and direction of character transformation (e. g., Kluge, 1994). In some cases, however, chromosomal data have been providing very convincing evidence for monophyly in some agamid groups (e. g., Diong et al, 2000;Honda et al, 2002). Also, chromosomal investigation may clarify biological species that are cryptic to morphological approaches (King, 1993: see Ota [1988 for example of an agamid group).…”

We karyotyped four lizards, Acanthosaura armata, Bronchocela cristatella, Calotes emma, and C. versicolor, all belonging to the tropical Asian Glade of the family Agamidae. The karyotype of A. armata consisted of 12 metacentric macrochromosomes and 20 microchromosomes, whereas B. cristatella had 14 metacentric macrochromosomes and 20 microchromosomes. Except for the presence of 22 microchromosomes, the karyotypes of the two Calotes species were similar to that of A. armata. The 20 microchromosome state in the A. armata karyotype may have emerged in the ancestral lineage common to Gonocephalus robinsonii, whose karyotype also exhibits a 12M+20m format. Comparison of the present results with previously published information suggests the presence of cryptic taxonomic diversity in B. cristatella and C. versicolor.

Agamid lizards (Agamidae, Acrodonta, Sauria, Reptilia) of Vietnam

Being a hotspot of plant and animal diversity and endemism, Vietnam is important for the conservation of biodiversity on a global scale. It is one of the most threatened areas in tropical Asia in terms of destruction of tropical rain forest as an environment with a unique Vietnamese fauna. Previous summaries on Vietnamese agamids, their taxonomy and distribution were published in the works of Bourret 1943, Nguyen & Ho 1996, Bobrov 1995, Ziegler 2002and Ziegler et al. 2006. New, intensive study of the fauna of Vietnam as well as new opportunities offered by molecular methods make clear that taxonomic diversity in Southeast Asia is underestimated. The aim of this paper is to show and review the taxonomic diversity of different evolutionary lineages of agamids and their geographical distribution. This is based on new results of the authors and most recent evaluation of literature sources.
