| 3:13a | [Botany • 2025] Lysimachia brevicaulis (Primulaceae) • A New Species from Limestone Karst of Northern Laos
Abstract Lysimachia brevicaulis Y.H. Tan & D.L. Quan (Primulaceae) is described and illustrated as a new species from a limestone karst in Oudomxay Province, Laos. It is tentatively placed in the subgenus Idiophyton. The new species is morphologically close to L. verbascifolia but can be distinguished from it by its underdeveloped stem, smaller leaf blades, solitary flowers, villous calyx, abaxially reddish brown and puberulent corolla, shorter anthers and styles, and green fruits.
Lysimachia brevicaulis Y.H. Tan & D.L. Quan sp. nov. Etymology: The specific epithet brevicaulis refers to the short stem, one of the key characteristics of the new species.

| 3:52a | [Herpetology • 2025] Calotes zhaoermii • A New Cryptic Species of Calotes (Reptilia: Agamidae) from Southeastern Xizang Autonomous Region, China
Abstract Based on both morphological and genetic data, we describe a new cryptic species of Calotes from southeastern Xizang Autonomous Region, China. The new species was confused with C. paulus, and it is morphologically most similar to members of the C. paulus complex (namely C. paulus, C. sinyik, and C. zolaiking), but the new species shows considerable genetic divergence from closely resembled congeners and can be diagnosed morphologically by having more vertebral crest scales, more scale rows at mid body, and more caudal vertebrae. With the description of the new species, we also remove C. paulus from the reptile fauna of China. Reptilia, cryptic diversity, Draconinae, Himalaya, herpetofauna, taxonomy
Calotes zhaoermii sp. nov. Wang, Shu, Li, Guo, Che Etymology. The new species name, zhaoermii, is derived from the name of the landmark Chinese herpetologist, Dr. Zhao Er-Mi, who had conducted extensive surveys back in 1973 in Muotuo County of Xizang Autonomous Region where the new species is native to and contributed substantially to the herpetological knowledge both in China and across Asia. We name the new species after Dr. Zhao in honoring his contribution to herpetologicalr esearch. We suggest “赵氏树蜥” (Pinyin: Zhao Shi Shu Xi) as its Chinese common name, and Zhao’s tree agamidas its English common name.

| 8:27a | [Botany • 2025] Pyrus zhaoxuanii (Rosaceae) • A New pear Species from Danxiashan Mountain, Guangdong, China
Abstract Pyrus zhaoxuanii is described as a new species from Guangdong Province, China, within the genus Pyrus, specifically under P. subg. Pashia. Although it shares morphological similarities with P. calleryana, P. zhaoxuanii can be distinguished by its uniquely small, obovate, leathery leaves, which have an obtuse apex and short petioles. A phylogenetic analysis based on single nucleotide polymorphisms (SNPs) indicated that P. zhaoxuanii forms an independent branch within Pyrus and is categorized in the Oriental clade, P. subg. Pashia. Currently, this species has only been recorded in the Danxiashan National Nature Reserve. Considering its potential distribution and population size, we recommend classifying this species as Least Concern (LC) according to the IUCN Red List classifications and criteria. Key words: Danxia landscape, new species, phylogeny, Pyrus
Pyrus zhaoxuanii X.W.Yi, B.B.Liu & Q.Fan, sp. nov. Chinese name. 昭璇梨 Diagnose. Pyrus zhaoxuanii is similar to P. calleryana, but can be differentiated by its small, obovate leaves, short petioles, pronounced stem thorns, and shrubby habit. Etymology. Pyrus zhaoxuanii is named in honor of Prof. Zhao-Xuan Zeng (1921–2007), a famous geographer of South China Normal University, who made significant contribution to the study of danxia landscape.
