Oxyporus bifasciarius Zheng, Li, and Liu, 2010 was originally described from a female specimen from Yunnan, China. Based on 17 male and three female specimens, we provide the first description of the male of O. bifasciarius (Fig. 1) with the following data: CHINA: Sichuan, Jiulong County, 28°57′N, 101°34′E, 3,340 m, living in fungi in shrubwood (Fig. 2), 6 August 2020, Tang Ting and Xiong Chao. This is also the first record of this species from Sichuan Province. All specimens are deposited in the Insect Collection of China West Normal University (CWNU). Terminology of the main parts of the endophallus follows Tokareva et al. (2021). The following abbreviations, based on Senda (2021), are used: AL—antennal length; AW—abdominal maximum width; BL—body length, apex of the clypeus to apex of the abdomen; EL—elytral maximum length; ESL—elytral suture maximum length; EW— elytral maximum width; EYL—eye maximum length; FBL—forebody length (HL + PL + EL); HL—head length, apex of clypeus to posterior margin of head capsule; HW—head maximum width; PL—pronotal maximum length; PW—pronotal maximum width; TL—temple maximum length. All body measurements are in millimeters (mm).
