Many early descriptions of species of the genus Takydromus were based on limited diagnostic characteristics. This has caused considerable challenges in accurate species identification, meaning that a number of cryptic species have been erroneously identified as known species, resulting in substantially underestimated species diversity. We have integrated evidence from morphology and DNA sequence data to describe a new species of the Asian Grass Lizard, Takydromus albomaculosus sp. nov., based on two specimens from Tianjingshan Forestry Station, Ruyuan County, Guangdong Province, China. The new species can be distinguished from other known Takydromus species by distinctive morphological differences and significant genetic divergence in the mitochondrial COI gene. Morphologically, the new species differs from the known 22 congeners in the following combination of characters: relatively large body size, SVL 70.9 mm in female, 65.5 mm in male; presence of three or four pairs of femoral pores and four pairs of chin-shields; supraoculars three, rarely four, the posterior loreal either in contact with the anteriormost supraocular or not; the presence of supraciliary granules; the presence of six rows of ventral scales, strongly keeled in the male, and smooth but with the outermost row keeled in the female; the presence of enlarged and keeled lateral scales in a row above the ventrals, but shorter than the ventrals; subdigital lamellae 23-24 under the fourth finger and 29-30 under the fourth toe; dorsal surface brown, ventral surface green, flank dark brown or brown black with several prominent white round spots; the presence of a pair of white longitudinal dorsolateral stripes and a pair of white longitudinal ventrolateral stripes. Takydromus albomaculosus sp. nov. represents the twenty-third species of this genus, of which six species occur in northern Guangdong, where the biodiversity level of Takydromus is the second highest in the world, just below that of Taiwan.

A new species, Takydromus yunkaiensis J. Wang, Lyu, & Y.Y. Wang, sp. nov. is described based on a series of specimens collected from the Yunkaishan Nature Reserve located in the southern Yunkai Mountains, western Guangdong Province, China. The new species is a sister taxon to T. intermedius with a genetic divergence of 8.0–8.5% in the mitochondrial cytochrome b gene, and differs from all known congeners by a combination of the following morphological characters: (1) body size moderate, SVL 37.8–56.0 mm in males, 42.6–60.8 mm in females; (2) dorsal ground color brown; ventral surface green to yellow-green, but light blue-green on chin and throat, posteriorly green in adult males; (3) dorsolateral lines paired, strikingly yellowish-white bordered by black above and below, invisible or indistinct in juveniles and adult females; (4) flanks of body blackish brown with light brown marks in adult males; (5) presence of four pairs of chin-shields; (6) four supraoculars on each side; (7) presence of a row of supracilary granules that separate supracilaries from supraoculars; (8) two postnasals; (9) enlarged dorsal scales in six longitudinal rows on trunk of body, with strong keel; (10) enlarged ventral scales in six longitudinal rows, strongly keeled in males, smooth but outermost rows weakly keeled in females; (11) enlarged and keeled lateral scales in a row above ventrals; (12) femoral pores 2–3 on each side; (13) subdigital lamellae 20–23 under the fourth finger, 23–30 under the fourth toe; and (14) the first 2–3 subdigital lamellae under the fourth toe divided. The discovery of Takydromus yunkaiensissp. nov. brings the total number of species of this genus to 24, of which nine occur in mainland China.

Ota (personal communication) reidentified this photographic voucher as the Ocellated Grass Lizard, Takydromus sexlineatus ocellatus (Guérin-Méneville 1829) (see Cowan 1971; Zhao and Adler 1993 for publication history), a morphologically similar lacertid indigenous to a region of southeastern Asia that includes eastern India, southern China (including Hong Kong), eastern Myanmar, Thailand to Vietnam, and southward into the northern Malay peninsula (Zhao and Adler 1993;Manthey and Grossmann 1997), although the exact indigenous distribution of specimens putatively identified as T. sexlineatus, as well as subspecific classification of the species requires further study (Lin et al 2002;Ota et al 2002;Bhupathy et al 2009).…”

In a recent issue of Zootaxa, Krysko et al. (2011) compiled and evaluated vouchers (i.e., specimens and photographs), and confirmed three intercepted and 137 introduced species of non-indigenous amphibians and reptiles in Florida from 1863 through 2010. Trying to improve upon previous methodologies of reporting new non-indigenous species, we stressed the importance of providing all known data along with vouchers to help keep numbers of species consistent, accurately identify species, document when and where a particular species is found, and identify the invasion pathway and current invasion stage of each species. High resolution digital images of each of the 83 newly confirmed taxa were registered in MorphoBank (www.morphobank.org; project number p536). Physical voucher specimens are always preferred over photographs, as it can be quite difficult to accurately identify species that are morphologically similar or cryptic, especially in species that we are unfamiliar with or may originate in different countries. In this paper we attempt to correct the species names of four taxa as well as the family and authority names attributed to one species.
