“…These include fossorial species that often evade detection in surveys, such as ichthyophiids, anguids, dibamids, and calamarines; strictly arboreal species that can also evade detection; species that are part of poorly defined taxonomic groups such as those of the genera Dinodon (see , Oligodon (see David et al, 2008b, c), Amphiesma (see , and Draco (see McGuire and Heang, 2001). Combined survey efforts and morphological and molecular analyses will likely resolve some of the wide-ranging cryptic species complexes such as those of the genera Paramesotriton (see , Fejervarya (see Toda et al, 1998a, b;Veith et al, 2001), Limnonectes (see Emerson et al, 2000;Evans et al, 2003;, Odorrana (see Fei et al, 2001;Li et al, 2001;Bain et al, , 2009cOrlov et al, 2006c), Hylarana (see Murphy et al, 1997;Matsui et al, 2002), Polypedates (see He, 1999;Orlov et al, 2002b;, Rhacophorus (see Ohler and Delorme, 2006), Calotes (see Zug et al, 2006), Leiolepis (see Schmitz et al, 2001), Takydromus (see Lin et al, 2002), Dixonius (see Ota et al, 2001), Emoia (see Emilio et al, 1996), Naja (see Wü ster and Thorpe, 1992), possibly Sacalia (Shi et al, 2008), and several genera of green tree vipers (see Malhotra and Thorpe, 2004a, b). This will result in an increase in the number of endemic species and a concomitant decrease in the number of widespread species.…”

The leopard tortoise (Stigmochelys pardalis) is the most widely distributed sub‐Saharan tortoise species, with a range extending from the Horn of Africa all over eastern Africa to the Republic of South Africa, Namibia and southernmost Angola. Using 1938 bp of mitochondrial DNA (cyt b gene, partial ND4 gene plus adjacent tRNA genes) from a nearly range‐wide sampling, we examined its phylogeographic structure and compared our findings with previously published GenBank sequences. We identified seven major clades that are largely parapatrically distributed. A few records of distinct haplotypes at the same locality or in close proximity could be the result of translocation of tortoises by man. The greatest diversity occurs in the south of the species’ range, with five out of the seven clades. Testing for isolation‐by‐distance suggests that the observed phylogeographic structure is the result of restricted geographical gene flow and not of historical vicariance. This is in sharp contrast to wide‐ranging thermophilic reptiles from the western Palaearctic, whose phylogeographic structure was significantly shaped by Pleistocene range interruptions, but also by earlier dispersal and vicariant events. Most cyt b sequences of S. pardalis from GenBank turned out to be nuclear pseudogenes, or to be of chimerical origin from such pseudogenes and authentic mitochondrial sequences, which argues for caution regarding uncritical usage of GenBank sequences. The recent revalidation of the two subspecies of S. pardalis was based on such a chimerical sequence that was erroneously identified with the subspecies S. p. babcocki. Furthermore, according to our data, the distribution of mitochondrial clades does match neither the traditional subspecies ranges nor the pronounced geographical size variation of leopard tortoises. We conclude that there is no rationale for recognizing subspecies within S. pardalis.

The Beal’s-eyed turtle (Sacalia bealei) is endemic to southeastern China and endangered due to poaching and habitat loss. Knowledge of S. bealei ecology is lacking and this study provides baseline information of its reproduction in a natural environment. We studied the reproductive ecology of S. bealei using X-ray, spool-and-line tracking, and direct observation. Six nesting females were successfully tracked and their nesting behaviors are documented in detail. Females produced a mean clutch size of 2.2 eggs (range 1–3). The hard-shelled eggs were ellipsoidal with a mean length of 45.50 mm, a mean width of 23.20 mm, and mean weight of 14.8 g. The relative clutch mass was 9.47%, while the relative egg mass was 4.60%. The mean incubation period was 94.7 days with a mean nest temperature of 25.08 °C. Hatchlings had a mean weight of 9.7 g, carapace length of 40.1 mm, carapace width of 33.3 mm, carapace height of 17.4 mm, plastron length of 31.6 mm, and plastron width of 25.4 mm. The results of this study provide important information to inform conservation plans and ex-situ breeding for this endangered species.
