The Asian leaf litter toad genus Leptobrachella contains more than 100 species widely distributed in southwestern Asia.However,the systematic profiles of this group remain unresolved.Osteological morphology is important for taxonomic and phylogenetic studies.However,few studies have focused on the osteology of the genus.Herein,we comprehensively described the osteological features of a representative species L.bijie based on micro-CT scanning and double-staining methods.The results show that the skull of adult L.bijie is well-ossified,exhibiting sexual dimorphism and minimal intraspecific variation.The skull length is slightly greater than the width,with the maxilla slightly overlapping with the quadratojugal.The nasal connects with the sphenethmoid in males,but only part or not connects with the sphenethmoid in females.The transverse processes of the sacrum are robust and symmetrically butterfly-shaped,and the presacral vertebrae are procoelous.The pectoral girdle is arciferous.The phalangeal formula is 2-2-3-3 for the hand,and 2-2-3-4-3 for the foot.This study provides the first detailed and comprehensive osteological accounts of the genus Leptobrachella.
