越南南部发现掌突蟾属一新种（两栖纲：角蟾科）

Abstract

We describe a new species of megophryid frog from Phu Yen Province in southern Vietnam. Leptolalax macrops sp. nov. is distinguished from its congeners by a combination of the following morphological attributes: (1) body size medium (SVL 28.0–29.3 mm in three adult males, 30.3 mm in single adult female); (2) supra-axillary glands present, creamy white; ventrolateral glands indistinct; (3) tympanum externally distinct; (4) dorsal skin roughly granular with larger tubercles, dermal ridges on dorsum absent; (5) rudimentary webbing present between fingers I–II and II–III; rudimentary webbing between all toes; fingers and toes without dermal fringes; (6) in life ventral surface greyish-violet with white speckling; (7) supratympanic fold distinct, dark brown in life; (8) iris bicolored, typically golden in upper half, fading to golden green in lower half; (9) tibia short (TbL/SVL 0.44–0.45 in males); and (10) eyes large and protuberant (ED/SVL 0.15–0.16 in males). From all congeners for which comparable sequences are available, the new species differs markedly in the 16S rRNA mitochondrial gene sequence (P-distance>5.7%). The new species is currently known only from montane evergreen tropical forests of Song Hinh District, Phu Yen Province, and M’Drak District of Dak Lak Province at elevations of 470–630 m a.s.l.. We suggest the new species should be considered as Data Deficient following the IUCN’s Red List categories. We also report a previously unknown Leptolalax mtDNA lineage from an evergreen tropical forest in the Hoa Thinh District of Phu Yen Province, which may also represent an undescribed species.

A new species ofLeptobrachium(Anura, Megophryidae) from western Thailand

“…We used the primers 16SL-1 and 16SH-1 from Hedges (1994) to amplify ∼537 base pairs of the 16S rRNA mtDNA gene for the new species. For PCR conditions and primer sequences see Poyarkov et al (2015), Nguyen et al (2018) and Duong et al (2018). PCR products were sent to Evrogen (Moscow, Russia) for subsequent purification and sequencing in both directions.…”

A new species of the genus Leptobrachella Smith, 1925 (Anura, Megophryidae) from Guizhou, China

“…With the development of DNA barcoding technology and extensive fieldwork, more and more cryptic species in this genus have been reported. From 2016 to 2020, a total of 28 species were described (Eto et al 2016(Eto et al , 2018Rowley et al 2016Rowley et al , 2017aYang et al 2016Yang et al , 2018Yuan et al 2017;Duong et al 2018;Hou et al 2018;Nguyen et al 2018;Wang et al , 2019Chen et al 2019Chen et al , 2020Hoang et al 2019;Li et al 2020;Luo et al 2020). The discovery of these species indicates that the species diversity of the genus is underestimated, and there still may be a large number of undiscovered cryptic species.…”
