Seventy Pipistrellus abramus samples were caught to analyze their sexual dimorphism and mophological characteristics. The mean HB and FA were 50.86 mm and 34.93 mm, respectively, based on external measurements and skull shape. The length of the TL, Hfcu, and Tra were approximately 70%, 55.6%, and 38% of the HB, Tib, and E, respectively. Both the lambdoid crest and the sagittal crest were well developed and the H.BC was approximately 84% of the W.BC. P2 was inside the toothrow and metacone of canine was clearly visible. According to the analysis of sexual dimorphism, the following characteristics were different in between males and females: WS, C-M3, C-C, M3-M3, LOM, LUC, and i-m3. The WS, C-M3, C-C, M3-M3, LOM, and i-m3 were bigger in females than males, whereas the LUC was bigger in males.
