An Annotated List of Lizards(Sauria: Squamata) Recorded from the People's Republic of China

From the perspectives of biodiversity conservation and management, there is an urgent need to have at hand current synopses of classification and distributions of species. In this paper, we review and summa rize the classifica tions, Chinese a nd English names, type specimens, type localities and distributions of China’s lizard fauna to promote scientific exchange and species conservation among relevant people in China and internationally. As of December 31, 2020, a total of 230species of lizard, belonging to 44 genera and 12 families,have been recorded from China, including 4 invasive species: 2 in the family Gekkonidae, 1 in Iguanidae and one in Dactyloidae. There are 115 endemic species, accounting for 50% of this group. The proportion of endemic species to China was the highest in the family Eublepharidae(84.62%), and the number of endemic species to China was the highest in the family Agamidae(42 species). The species distributions and classifica tion in the “Fa una Sinica(Reptilia 2): Squamata(Lacertilia)” were updated.Among the provincial administrative units, there is a larger number of species in the southern provinces, such as Yunnan, Guangdong, Guangxi and Taiwan. Sichuan, Yunnan, and Taiwan harbour relatively more endemic species than others. A total of 154 species of lizards were first discovered in China, and the type localities of these species are concentrated in Yunnan, Taiwan, Tibet, Xinjiang, and Sichuan.

A New Species of Glyphoglossus Günther,1869(Anura:Microhylidae) from Western Yunnan,China

A new species of microhylid frog of the genus Glyphoglossus Gunther,1869 is described from Huadianba,Cangshan Mountain,Dali Bai Autonomous Prefecture,Yunnan Province,China.Glyphoglossus huadianensis,new species,is compared with congeners from China and other parts of Southeast Asia,and was distinguished from the others by the following combination of characters:adult male body size up to 37.8 mm;pupil rounded;supra tympanic fold distinct;tympanum concealed;toe tips obtuse;subarticular tubercles prominent and rounded;foot webbing extensive;outer metatarsal tubercle present;dorsum tuberculate,yellowish-brown/earth-yellow;and a pair of conspicuous large round spots in groin.The new species is the tenth species of Glyphoglossus to be described,and the second known from China.

Insulin receptor participates in the peripheral olfactory processes of honey bees (Apis cerana cerana)

Insulin receptors(InR)are an integral component of the insulin/insulin-like growth factor signaling pathway,which plays a vital role in insect development,lifespan,reproduction,and olfactory sensitivity.However,whether InR participate in the periph-eral olfactory system of insects remains unclear.Recently,we found that 2-heptanone(2-HT)affects AcerlnR expression,the gene for an InR protein,in Apis cerana cerana.We then examined the spatiotemporal expression profile of the gene in A.cerana cerana.The mRNA of AcerlnR was primarily expressed in the antennae,wings,and legs of forager bees,which are probable chemosensory tissues.The results of fluorescence competitive binding assays,combined with site-directed mutagenesis,demonstrated that AcerOBP6 and AcerOBP14 exhibit strong binding affinities to 2-HT.Furthermore,after foragers were fed with double-stranded AcerlnR,the expression levels of AcerOBP6 and AcerOBP14 decreased significantly,as did the electroantennogram responsiveness to 2-HT and some other odorants.In conclusion,our findings provide a foundation for understanding the in-volvement of AcerlnR in the odor perception of A.cerana cerana.Moreover,they offer novel insights into the olfactory recognition mechanism in insects.
